The new Mercedes-Benz F 125! research vehicle
Redefinition of automotive luxury:emission-free driving in First Class
As a highlight marking 125 years of the automobile, Mercedes-Benz is presenting a visionary outlook on future technical developments in the luxury segment. The F 125! research vehicle anticipates future trends and prepares the way for implementation of an innovative premium concept for large, luxurious automobiles.
In the F 125! Mercedes-Benz rigorously follows its vision of emission-free driving with hydrogen power, underlining the potential of H2 as an energy source for the future. While previous Mercedes-Benz research vehicles have "looked ahead" by roughly one vehicle generation - seven to eight years - the F 125! as the latest technological visionary goes a whole step further, by more than two generations to the year 2025 and beyond.
"With the F 125! we want to show that large, comfortable and safe saloon cars have an excellent future, partly because they are able to operate with no emissions. The legend that is the S-Class will continue into the future thanks to intelligent solutions that always have the customer's needs in mind," says Prof. Dr. Thomas Weber, member of the Board of Management of Daimler AG, responsible for Group Research and Mercedes-Benz Cars Development. "The new research vehicle illustrates and underlines this claim to leadership with innovative ideas and traditional Mercedes strengths in the areas of design, safety, comfort and performance."
Innovative ideas reaffirm the claim to leadership in the luxury segment
The F 125! demonstrates how completely emission-free, individual mobility might be realised in the luxury segment in the future. The researchers and developers at Mercedes-Benz have incorporated already well-proven concepts and technologies which are not yet available today, but for which basic
research has shown great future promise, and therefore a realistic chance of implementation in future series-production cars. The decisive innovations are:
On this basis the F 125! was created as an innovative four-seater luxury saloon with a powerful, emission-free electric drive system based on the fuel cell technology developed to series production maturity by Mercedes-Benz. This study combines pioneering and highly efficient storage, drive and bodyshell technologies with unique control and display concepts. The research vehicle also presents itself with an expressive design which transfers the classic Mercedes design idiom into the future.
Highlights of the F 125!:
Revolutionary: structural integrated hydrogen composite storage unit
To store the hydrogen as the fuel of the future, Mercedes engineers adapted a technology which is still the object of basic research. This opens up completely new perspectives with respect to the vehicle architecture and operating range. "The structural integrated hydrogen composite unit of the F 125!represents a real technological revolution, as it allows the hydrogen tank to be fully integrated into the bodyshell structure for the first time. In the future, vehicles with emission-free fuel cell drive systems could achieve the operating ranges of current diesel models with no loss of interior space," says Prof. Dr. Thomas Weber. Based on the current level of know-how, Mercedes specialists consider it possible that they may develop this technology to series production level from 2025.
The tank integrated into the floor assembly has a capacity of around 7.5 kg of hydrogen. Compared to the high-pressure tanks in use today, the H2 tank potentially requires less installation space. This is because to withstand a pressure of up to 700 bar, current tanks need to be cylindrical in shape, and owing to this round cross-section there are inevitably "cavities" between tanks installed next to or above each other. In contrast, tanks that can be filled at a pressure of 30 bar or less can be better integrated into the bodyshell. At the same time they are able to act as "structural" components.
Lithium-sulphur battery: compact and powerful
A highly advanced, very powerful lithium-sulphur battery is envisaged for the F 125!. It has a storage capacity of 10 kWh and is installed behind the rear seats. Combining the fuel cell drive system with the innovative lithium-sulphur battery makes a total operating range of up to 1000 km possible, of which up to 50 km can be under battery-electric power alone. It can be inductively charged at "intelligent" charging stations, and the convenient charging process can be monitored by smartphone. When designing the F 125!, the developers worked on the assumption that by the time of its introduction into series production, this battery type will be capable of energy densities up to 350 Wh per kg. This would represent roughly a doubling of current performance. The real potentials of this technology are however the subject of basic research, and are still difficult to assess at present.
Further development of the fuel cell as an energy source
At the heart of the drive system lies a particularly powerful further development of the Mercedes-Benz fuel cell stack which has demonstrated its efficiency and day-to-day suitability e.g. in the successful B-Class F-CELL World Drive this year.
On 29 January, marking the 125th birthday of the automobile, Mercedes-Benz commenced the first circumnavigation of the globe with fuel cell powered electric cars in Stuttgart - covering more than 30,000 kilometres on four continents and through 14 countries. The three fuel cell powered B-Class cars and their backup vehicles returned safely to Stuttgart 125 days later.
The stack in the F 125!, which is further improved with respect to performance, consumption and practical suitability, provides the power for four powerful electric motors installed near the wheels, which ensure sporty, superior performance figures. All in all the modular e4MATIC system, which also uses improved drive components from the SLS AMG E-CELL, generates a continuous output of 170 kW (231 hp) and a peak output of 230 kW (313 hp).
This accelerates the F 125! to 100 km/h in 4.9 seconds, with a top speed of 220 km/h. Nonetheless, NEDC fuel consumption is only 0.79 kilograms of hydrogen per 100 kilometres (= 2.7 litres diesel equivalent).
Always online, always connected: "@yourCOMAND"
With the visionary infotainment system"@yourCOMAND", the F 125! provides an outlook on future Mercedes-Benz telematic systems. Its trailblazing features include:
In Natural Handling, operation is substantially by natural speech supplemented with touch and intuitive hand-gestures. In the interests of maximum driver-fitness and operating safety, the F 125! becomes the perfect, always alert companion for its driver and passengers. The possibilities go well beyond those of current systems. The driver can e.g. request news items that are tailored to his personal needs, and make specific, contextual enquiries, without removing his hands from the wheel. The COMAND of tomorrow also becomes proactive.
In the future, the driver will be able to start with the traffic report or retrieve personal messages before the selected music programme begins. The weather report will then automatically come on before the journey ends, for example. Thanks to the mood-based configuration function "Moods", such individual adjustments will be completed in a matter of seconds in future. The F125! also opens up completely new dimensions when it comes to external communication and the use of social networks. With the help of the Social Community Assistant, the driver alone can decide who is allowed to "disturb" him, or who receives information.
Thanks to the Seamless Experience functions, the multimedia systems of the F 125! are seamlessly and cross-functionally networked, socially interactive and non-distracting.The exchange of information is no longer impeded or interrupted on journeys, but is an integral part of the concept. Because of constant connectivity with the Cloud, the driver has seamless access to all the media he normally uses. The tedious synchronisation of different communication and entertainment devices is also completely eliminated. The so-called "digital lifestyle" of many customers can therefore be continued both seamlessly and safely when on board.
Sensory Perfection in the F 125! means high-end sound and high-resolution screens with brilliant, individual displays. If required, the autostereoscopic 3D display for spatial representation of the instrument cluster is able to show relevant information in clustered form. The 3D image adapts natural visual habits, allows a better overview and thus relieves the driver of stress. The head unit in the upper section of the centre console uses projector-beam technology, and is controlled via a touchpad with 3D fingertracking located within easy reach of the driver.In addition to the head unit, the integrated selection bar enables the instrument cluster and rear-view display to be selected. Activated in this way, these displays can also be centrally operated. A further, retractable 17-inch display is installed on the front passenger side, and this is fully controlled by hand gestures. In this way a rear passenger can select his personal film programme with no physical contact.
A high-resolution wide-image display allows the entire traffic situation behind the vehicle to be conveniently monitored, and makes exterior mirrors unnecessary. The image is adapted to human perceptive powers at all times, and once again provides a much clearer overview with more rapid and intuitive registration of the relevant traffic situation.
The vehicle and its multimedia system, as well as all applications and contents, can be completely remote-controlled using the Remote Convenience functions. This e.g. means that via the vehicle's specific homepage, authorised individuals have access at all times to information such as the fuel level, next scheduled service or fuel consumption. Just as easily, a home PC or of course a smartphone can be used for remote configuration of the onboard navigation or entertainment system, and to select individual interior temperature settings for each seat.
New assistance systems: recognising dangers, travelling in style
With the help of innovative driver assistance systems, the touring saloon of the future defuses even "invisible" hazards and relieves driver stress in many standard situations. If the driver requires, the F 125! is able to carry out frequently occurring driving manoeuvres autonomously.
Advanced Driving Assist allows lane-changes on multi-lane, one-way roads, and in a further development stage even automatic overtaking manoeuvres. Thanks to radio-based networking with the environment, so-called Car-to-X communi-cation, the F 125!is also able to exchange information with other vehicles, a specially equipped infrastructure incl. traffic lights or warning signs and traffic control centres. Specific applications might include a warning of approaching emergency service vehicles, well before the driver can see or hear them, a reminder that other vehicles have the right of way at obscure road junctions, or obstacles on the road.
Mobility of the future – Utopias shaping our tomorrow
It was visionaries and dreamers who prepared the way for "automobility". The first tentative steps were taken at the end of the 19th Century – in a techno-logical environment where the steam engine dominated the world of power generation. The steam locomotive added motion to this machine, and tracks were laid everywhere.
The idea of fitting coach-like vehicles with compact, fast-running internal combustion engines to make individual, easy and comfortable mobility possible beyond the railway tracks was seen as "utopian" at the time – i.e. synonymous with "science fiction" or "fantasy".
Visionary engineers and utopians such as Carl Benz, Gottlieb Daimler, Wilhelm Maybach or Rudolf Diesel refused to be daunted, however. With the F 125! Mercedes-Benz is once again demonstrating this pioneering spirit.
F 125! – a specific outlook on the vision of emission-free driving
With the new Mercedes-Benz research vehicle, the vision of emission-free driving with large, luxurious automobiles takes on a concrete form. The F 125! shows that the mobility of the future is emission-free and sustainable, comfortable and visually very appealing. It embodies technical and design innovation, and shows the way towards a society able to cope without fossil fuels.

Compact sports tourer: the new B-Class from Mercedes-Benz
Heralding a new era in the compact class
Substantially more agile and efficient, but as comfortable and spacious as ever – the new B-Class from Mercedes-Benz is a winner on all fronts. The vehicle's lower height and more upright seat position provide for a first impression that hints at the compact sports tourer's dynamic credentials.
With a new four-cylinder petrol engine featuring direct injection and turbocharging, a new diesel engine, a new dual clutch transmission, a new manual transmission and new assistance systems, the front-wheel-drive car also rings in a new technological era for compact cars from Mercedes-Benz.
"No model change in the history of Mercedes-Benz has ever seen so many new developments introduced in one fell swoop," stresses Prof. Dr. Thomas Weber, Member of the Board of Management responsible for Group Research and Mercedes-Benz Cars Development. "Future B-Class customers will benefit from this quantum leap in terms of exemplary low fuel consumption and CO2 emissions combined with driving pleasure, plenty of space and the highest standard of safety that has ever been available in this class."
The new B-Class (length/width/height: 4359/1786/1557 millimetres) will be making its way to European dealers in November 2011.
The exterior design: perfect space in a most attractive guise
The new B-Class is a typical Mercedes sports tourer, offering plenty of space combined with impressive dynamic performance as a hatchback saloon. The characteristic lines of the exterior design indicate both of these attributes: front and rear sport a width-emphasizing design, with a wide, prominent grille and headlamps extending along the sides at the front while the rear end features a wide rear window, two-piece tail lights with horizontally offset meander and a large tailgate with low loading sill.
The new sportiness and the outstanding aerodynamics are particularly evident in the side line: the bonnet flows seamlessly into the A-pillar and the roof line descends sleekly to the striking roof spoiler. The roof features a swage line which lends the vehicle a longer appearance. The pronounced wheel arches offset by dynamic feature lines under the beltline are a sporty interpretation of the current design line from Mercedes-Benz. The bottom edge of the body features dynamic side skirts which add a light touch to the vehicle's appearance. Refined details such as the exquisitely designed headlamps with the new spotlight element confirm the brand's unmistakable premium credentials which shine through in the compact segment, too.
Outstanding aerodynamics: astounding cd value despite station wagon rear end
An outstanding drag coefficient of cd = 0.26 places the new B-Class at the forefront of its market segment. Apart from the aerodynamic exterior design, numerous optimisation measures on points of detail such as the air flow around the front wheels, the underbody design and the cooling air flow are also crucial contributory factors to this excellent aerodynamic performance. Patents are pending for innovative details such as the serrated wheel arch spoiler. With the optional ECO Technology package which will be available in due course, the B-Class is even on a par with the world-class aerodynamic credentials of the E-Class Coupé, attaining a drag coefficient of cd = 0.24 which is nothing short of sensational for a vehicle with a station wagon rear end.
New concept: lower overall height but more space inside
The new vehicle concept underscores the dynamic aspirations of the new B-Class. The most striking aspect is the reduced height: at 1557 millimetres, the new model crouches almost five centimetres lower on the road than its predecessor. The seat height in relation to the road has also been reduced (minus 86 mm) in order to facilitate boarding, while maintaining a clear overview of the vehicle's contours.
In response to requests from many customers, the sitting position is more upright, however. At the same time, the headroom has been further improved. With maximum headroom of 1047 mm at the front (without sliding roof), the B-Class is among the most spacious cars in its segment in this discipline, too. The ergonomically expedient more upright sitting position in combination with a lowering of the vehicle's floor leads to a segment-leading degree of legroom (976 mm) at the rear which even surpasses that of the S- and E-Class.
The B-Class is optionally available with the so-called EASY-VARIO-PLUS system. This enables simple reorganisation of the interior so as to enable the transportation of bulky items. Features of the EASY-VARIO-PLUS system include fore/aft adjustment of the rear seats by up to 140 millimetres (thereby increasing the luggage compartment volume from 488 to 666 litres) and a front passenger seat whose backrest can be folded forward onto the seat cushion.
The interior design: superior quality in a new dimension
High-quality materials and finely structured surfaces, stylish details, precision workmanship and a new spaciousness – the interior of the B-Class defines a whole new benchmark in the compact segment.
Many features have been the reserve of higher classes of vehicle to date and embody Mercedes-Benz's special definition of quality and aesthetics. The dashboard is optionally available in ARTICO man-made leather finish and features stitching, for example. Four equipment packages (Chrome, Sports, Exclusive and Night package) enable individualisation according to personal tastes.
In the interior, the large, three-dimensional trim covering the entire dashboard first strikes the eye. It is available in four variants, covering a broad spectrum from modern through sporty to classic. Common to all versions is a high-class appeal combining an attractive look and feel with easy care and durability.
The three large round vents in the middle and their uniquely designed cruciform nozzles add a sporty attribute to the interior's emotional design idiom. The display, which is available in two sizes (5.8- and 7-inch) appears to hover over the vents. With its stylish design – the trim frame with galvanised finish contrasting with the piano black of the front panel – and slender lines, the colour display (TFT) is a highly attractive feature in the cockpit.
The 3-spoke steering wheel, which always incorporates a silver chrome insert in the middle spoke, the instrument cluster with four analogue round dials and suspended pointers in6 o'clockposition and the seats with contrasting stitching underscore the sporty character.
The drive: designed for maximum efficiency
The new B-Class features new petrol and diesel engines as well as new manual and automatic transmissions. All transmissions and engines have been developed in-house, with production taking place at the plants in Stuttgart-UnterÂtürkheim and -Hedelfingen, Rastatt/Baden, Gaggenau/Baden and KÃ¶lleda/ Thuringia. The simultaneous development process enabled perfect coordination of engines and transmissions, e.g. with regard to implementation of the ECO start/stop function which features as standard on all B-Class models.
Common features of the new drive systems are the use of state-of-the-art technologies for maximum efficiency, very smooth running, high tractive power right from low revs, sustainability in terms of impending emissions standards and low weight. For the purposes of transverse installation the engines, all of which are turbocharged, and the two transmissions are very compactly designed, providing the B-Class with an exemplary small turning circle for a front-wheel drive vehicle of eleven metres. The engine and transmission suspension disposes of a four-point mounting system comprising engine mount, transmission mount and two self-aligning supports. This suspension system has been designed specifically to meet the requirements of the high-torque engines with regard to minimum noise levels. The hydraulic damping integrated in the transmission mount is a key contributory factor to the exceptionally high ride comfort.
The new four-cylinder petrol engines (internal designation M270) mark the launch of a completely new engine series. The combustion process is based on the third-generation Mercedes-Benz direct injection system which was introduced last year with the BlueDIRECT V6 and V8 engines. Its use in the B‑Class marks this technology's debut in the compact segment. The new four-cylinder engines have been designed for both transverse and longitudinal installation. In the new B-Class they are initially available with a displacement of 1.6 litres, as the B 180 rated at 90 kW (122 hp) and the B 200 with an output of 115 kW (156 hp). Their maximum torque of 200 and 250 Nm respectively is available from an engine speed of 1250 rpm.
The new four-cylinder diesel engine is a further development of the OM651 deployed in the C- to the S-Class, a common rail direct-injection engine of the third generation. With its displacement scaled down to 1.8 litres and numerous optimised points of detail, this is the first time that the compression-ignition engine has been mounted transversely in a Mercedes-Benz car. The B 180 CDI generates 80 kW(109 hp) of power, while the B 200 CDI has an output of 100 kW (136 hp). The maximum torque stands at 250 Nm from 1400 rpm for the 80 kW variant and 300 Nm from 1600 rpm for the 100 kW variant.
Another Mercedes-Benz premiere is the new 7G-DCT dual clutch transmission in the B-Class. This transmission is extremely compact, extremely variable with regard to adaptation of the engine speed thanks to seven gears, features an electric oil pump for start/stop capability, shifts gear without any interruptions in tractive power and combines the comfort of an automatic with the efficiency of a manual transmission.
The new 6-speed manual transmission designed along similarly compact lines as a three-shaft transmission is a close relative of the DCT. Extremely easy gear shifting, low shift forces, low internal friction and a low weight are among its most important characteristics.
Chassis and suspension: refined sportiness now for the sports tourer, too
"Fascinatingly agile" is the assessment of all test drivers who have put the new B-Class through its paces to date. Three factors are instrumental to the substantially enhanced dynamic performance in comparison to its predecessor, which does not come at the cost of any compromises on comfort: the lowered centre of gravity, the new four-link rear axle and the upgraded ESP®Electronic Stability Programme. A sports suspension is optionally available for further enhanced agility. The centre of gravity has been lowered by a further 20 mm and the suspension additionally features sports dampers with amplitude-selective damping and a Direct-Steer system to emphasize the car's sporty character.
Steering: mechanical with electric assistance
The electromechanical steering of the B-Class has been redesigned. The electric motor of the servo assistance system is now located directly on the steering gear as a dual pinion EPS system, thereby optimising the package as a whole. A Direct-Steer system is available in combination with the sports package. The steering ratio becomes noticeably more direct at greater steering angles, enhancing the vehicle's handling and agility substantially.
The electromechanical steering system makes an important contribution to the vehicle's overall efficiency, as the steering assist function only requires energy when steering actually takes place.
New assistance and braking system reduces the risk of rear-end collisions
As a world first in the compact segment, the B-Class features a radar-based collision warning system with adaptive Brake Assist as standard, which lowers the risk of rear-end collisions. The COLLISION PREVENTION ASSIST system outputs a visual and acoustic warning to alert a possibly distracted driver to identified obstacles, and prepares Brake Assist for the most precise possible braking response. This is initiated as soon as the driver emphatically operates the brake pedal.
In contrast to systems currently on the market in the compact class, the new COLLISION PREVENTION ASSIST brake assist feature is not merely a system intended to minimise minor damage in urban traffic. Rather, this innovative solution is aimed at protecting motorists from typical rear-end collisions in dangerous traffic situations. Mercedes-Benz expects the new safety system to have a significant positive effect on accident statistics.
The democratisation of safety also encompasses an array of other assistance systems which have been adopted into the B-Class from the larger model series. These include:
Premiere in the compact class: PRE-SAFE® available for the first time
The PRE-SAFE® preventive occupant protection system which features in the B-Class is available for the first time in this vehicle category. This represents a further step in the ongoing democratisation of this innovation, which was premiered in the S-Class in 2002. Core features of PRE-SAFE® are reversible belt tensioning, the closing of side windows and sliding sunroof in case of critical lateral dynamics and adjustment of the fully electric front passenger seat with memory function to an ideal position for maximum effectiveness of the restraint systems. PRE-SAFE® is always activated in response to critical longitudinal and lateral dynamics and may also be triggered upon intervention by certain assistance functions.
The scope of restraint facilities takes special account of the B-Class' use as a family car. Great importance has been attached to the safety of the rear occupants. Belt tensioners, belt-force limiters and belt height adjusters come as standard on the outer seats. Rear sidebags are optionally available. Integrated child seats and automatic child seat recognition are available as in the predecessor. Driver and co-driver are provided with new pelvis bags which are able to cover the pelvis and the entire upper part of the body. For head protection, a windowbag is fitted as standard.
COMAND Online multimedia system with internet access
Internet access, the convenient LINGUATRONIC voice control system, two navigation solutions tailored to different budgets, connection for mobile audio devices and an intuitive operating concept – the information and communication systems in the B-Class offers excellent user-friendliness and a superior level of functionality which has been the reserve of higher categories of vehicle to date. It is the new multimedia generation from Mercedes-Benz which delivers these standards. The operating concept featuring the turn/push control in front of the armrest and the control knob on the head unit is also familiar from other Mercedes model series.
The COMAND Online multimedia system offers internet access. Customers can either surf the web as they wish while the car is stationary or call up a Mercedes-Benz app whose particularly fast page loading and simple operation make it suitable for use while driving. Integrated apps include Google™ Local Search and Weather, and the facility for downloading a route which has previously been configured on a PC using Google Maps and transmitted to the car.
All set for the future: modular "Energy Space" concept
The modular "Energy Space" concept means that the new B-Class is already designed to accommodate versions with an alternative drive: appropriate interfaces in the body shell enable the main floor panel to be modified and a step to be produced for the versions with alternative drive. An underfloor compartment covering part of the area under the rear bench seat offers space for alternative energy accumulators.
Mercedes-Benz Concept B-Class E-CELL PLUS
The future shape of the new compact car range: Mercedes-Benz presents electric car with Range Extender
Mercedes-Benz will be presenting its first electric vehicle with Range Extender at the 2011 Frankfurt International Motor Show in the guise of the Concept B-Class E-CELL PLUS. The combination of electric drive and petrol engine ensures excellent suitability for both everyday use and long journeys. The energy accumulator takes the form of a lithium-ion battery from Deutsche Accumotive, which enables local emission-free driving up to a range of 100 kilometres. Thanks to the additional three-cylinder petrol engine, the Concept B-Class E-CELL PLUS has a total range of up to 600 km. The concept vehicle presented at the 2011 Frankfurt International Motor Show provides a foretaste of the series which is to go into production in 2014. The Concept B-Class E-CELL PLUS adds an all-purpose battery-powered vehicle with Range Extender to Mercedes-Benz's range of electric vehicles.
A new addition to Mercedes-Benz's portfolio of electric cars is the near-series Concept B-Class E-CELL PLUS – a compact model that meets all the needs of daily motoring with a total range of up to 600 kilometres. As such, this electric vehicle is also ideally suited to long journeys and offers its driver unrestricted mobility. This is made possible by the combination of a powerful electric drive generating a peak power output of 100 kW and a continuous output of 70 kW with a 50 kW petrol engine. The latter performs a dual role: at low vehicle speeds it charges the battery via a generator. At higher speeds – on prolonged motorway stretches, for example – it additionally serves as a driving engine, acting on the front wheels together with the electric motor via a newly developed automatic transmission.
In all-electric, local emission-free mode the Concept B-Class E-CELL PLUS has a range of up to 100 kilometres. This covers over 80 percent of daily driving needs. The total range of up to 600 kilometres allows the vehicle to be used for long journeys, too. This means that the electric vehicle with Range Extender is fully suitable for everyday use and can be relied upon to reach its destination, even with a fully discharged battery. In combined driving mode the vehicle emits 32 grams of CO2 per kilometre.
"The Concept B-Class E-CELL PLUS shows that our new range of compact cars is all set for the future. The variant involving a battery-electric vehicle with Range Extender further broadens the range of alternative drive concepts from Mercedes-Benz," notes Prof Dr Thomas Weber, Member of the Board of Management at Daimler AG, responsible for Group Research and Mercedes-Benz Cars Development. "This innovative and highly flexible concept meets our customers' wish for emission-free driving coupled with a large range."
The vehicle concept – the best of two worlds
The Concept B-Class E-CELL PLUS is an electric vehicle meeting all daily motoring needs which combines the best of two worlds: all-electric driving and driving with a tried and tested high-tech combustion engine. This combination allows long journeys which to date have been the reserve of vehicles powered by a combustion engine alone or electric cars fitted with a fuel cell. The two drive units are extremely compact and are accommodated in the engine compartment at the front together with the transmission and the generator. The powerful lithium-ion battery and the fuel tank are located in a false floor at the rear – the so-called "Energy Space" – which has been developed specially for alternative drives. For other drive variants it is also possible to install gas or hydrogen tanks here, for example.
Intelligent control of the drive system for unrestricted mobility
The intelligent electronic control system of the Concept B-Class E-CELL PLUS ensures perfect handling in every driving situation. Activation and deactivation of the combustion engine take place fully automatically and go unnoticed by the driver. Electric motor and combustion engine work so intelligently together that the drive unit is able to select the most fuel-efficient mode in every driving situation in a fraction of a second – from stop and go in the city to speedy driving on the open road. With the Concept B-Class E-CELL PLUS there are basically two operating modes, depending on the battery charge status:
Highly efficient lithium-ion battery with long service life
The energy accumulator is accommodated in a false floor system at the rear of the vehicle – the so-called "Energy Space" – which has been developed by Mercedes-Benz specifically for alternative drives. The energy accumulator employed here is a particularly powerful state-of-the-art lithium-ion battery designed specifically for automotive applications. It is produced by Deutsche Accumotive GmbH & Co. KG, a joint venture of Daimler and Evonik.
The battery can be charged using any standard domestic power outlet or at a public charging station, by means of the charge socket integrated in the rear bumper and the 3.3 kW on-board charger.
When the car goes into production, convenient remote checking and remote configuration of the vehicle will be possible by means of the so-called Vehicle Homepage. The driver will be able to access his vehicle via the internet, using his PC or smartphone. In this way, it will be possible to check the current charge status of the lithium-ion battery or to verify the vehicle's current range on a map. A further feature is smart charging. This involves the customer selecting a desired time for the beginning of his journey. The system then ensures that the battery is fully charged and, if desired, that the vehicle is air‑conditioned at this point in time. The facilities offered by the Vehicle Homepage are rounded off by further convenience functions, such as a route planner designed specifically for electric vehicles.
Comfort and safety to the highest standard
In terms of safety and comfort, the Concept B-Class E-CELL PLUS meets Mercedes-Benz's high standards in every respect. The vehicle combines compact exterior dimensions with a spacious and variable interior and luggage compartment. Five full-size seats make it an all-round electric car for the family, leisure and general motoring. The new electromechanical steering and enhanced driving dynamics provide for refined sportiness in the field of electric mobility. A striking feature of the Concept B-Class is the copper-coloured linear graphic design which accentuates the vehicle and lends it a dynamic appearance. High-quality black nappa leather and copper-coloured double lap seams have been used in the interior.
The concept vehicle is a match for its siblings when it comes to active and passive safety features, too. Like all models of the new compact car generation, the Concept B-Class E-CELL PLUS also comes with COLLISION PREVENTION ASSIST, a new assistance system which will help to avoid rear-end collisions in future. In keeping with the ongoing democratisation of safety, the B-Class E‑CELL PLUS will also feature a number of additional assistance systems adopted from the larger model series.
As such, the Concept B-Class E-CELL PLUS sets new standards in the areas of compact electric vehicles with regard to comfort, safety and agility.

A generation ahead: the new Mercedes-Benz M-Class
Refinement meets efficiency
The third generation Mercedes-Benz M-Class scores particularly highly on outstanding energy efficiency, and on average the new model range consumes 25 percent less fuel than the previous models. One true champion in terms of fuel consumption is the ML 250 BlueTEC 4MATIC, which boasts an NEDC consumption of just 6.0 l/100 km (158 g CO2/km) and has a range of up to 1500 kilometres on a full tank. Further strengths of the premium SUV with permanent all-wheel drive include exceptional safety and well-balanced ride comfort as well as excellent driving dynamics both on and off the road. What's more, the ML features an array of new chassis developments and innovative dynamic handling control systems which further enhance both driving enjoyment and handling safety. A characteristic body design and a variable interior with a high wellness factor add to the richness of the driving experience in the new M-Class.
Prof. Dr. Thomas Weber, member of the Board of Management of Daimler AG with responsibility for Group Research and Mercedes-Benz Cars Development, puts it in a nutshell: "With the M-Class, it's always been a case of combining the comfort and luxury of a saloon car with the off-road characteristics and the emotiveness of an SUV." The fact that the new M-Class is as fuel-efficient as the economical saloon cars displaying the Mercedes star makes the all-wheel-drive model even more desirable. A range of state-of-the-art engines, a class-leading cd figure (drag coefficient) of 0.32 and extensive BlueEFFICIENCY measures lay the foundations for outstanding energy efficiency.
Complete and attractively priced model range
Despite the substantially upgraded equipment and appointments, prices for the ML 350 BlueTEC 4MATIC remain practically the same as for its predecessor (an increase of just 50 Euros). The prices at a glance:
|incl. 19% VAT|
|ML 250 BlueTEC 4MATIC||€46,200||€54,978,00|
|ML 350 BlueTEC 4MATIC||€49,350||€58,726.50|
|ML 350 4MATIC BlueEFFICIENCY||€47,700||€56,763.00|
According to Dr. Joachim Schmidt, Board Member of Mercedes-Benz Cars, Sales & Marketing: "The M-Class is a story of success. With more than 1.2 million vehicles sold, it is the best-selling SUV in its segment and also enjoys the loyalest customer base. We will be continuing this success with the new M‑Class, which will make an important contribution to our sales growth over the coming years."
To mark the launch of the new M-Class, there will be a limited special-edition model available in the shape of the Edition 1. This exclusive model includes an AMG Exterior Sports package and features an impressive and particularly exclusive interior. Prices start at €55,700 (€66,283 incl. 19% VAT) for the ML 250 BlueTEC 4MATIC Edition 1. Delivery of the M-Class to customers will commence in November this year.
A model of success: the M-Class sets new standards in the world of SUVs BlueTEC diesel units and the new generation of BlueDIRECT petrol engines ensure excellent economy and an outstanding life cycle assessment of the new M-Class. As Dr. Schmidt explains further: "The new M-Class has the potential to set standards in the SUV world once again: one average it consumes one quarter less fuel than its predecessor and as such will be the most economical vehicle in its segment – whether fitted with or without a hybrid drive."
As far as the diesel engines are concerned, now available solely as BlueTEC units with SCR emissions technology, the focus is firmly on downsizing and on the new version of the V6 CDI engine:
Thanks to AdBlue® emission control technology both diesel models comfortably meet the EU6 standard slated for introduction in 2014.
The ML 350 4MATIC BlueEFFICIENCY petrol-engine model, on the other hand, delivers a convincing performance thanks to the technical details of the new BlueDIRECT engine generation. The key here is the third-generation direct petrol injection system with spray-guided combustion and new piezo injectors that have an injection pressure of 200 bar, together with multi-spark ignition (MSI) and a new stratified combustion process. In this case, the NEDC consumption of 8.5 l/100 km is 25 percent lower than that of the previous ML 350 4MATIC model. The ML 350 4MATIC BlueEFFICIENCY meets the requirements of the EU5 standard, currently the strictest standard in force
for petrol models.
Long-distance champion: a high level of efficiency ensures a long range
The range calculated for a full tank of fuel is particularly impressive. With an NEDC consumption of 6.0 l/100 km, the ML 250 BlueTEC 4MATIC with the standard 70-litre tank can cover around 1170 kilometres before needing to stop for fuel. If the vehicle is fitted with the optional 93-litre tank, the car can even cover up to 1500 kilometres between refuelling stops.
|NEDC combined (L/100 km)||6.0||6.8||8.5|
|Tank capacity (litres)||70/93||70/93||78/93|
|Range per full tank ( km)||1170/1500||1030/1370||920/1090|
The excellent fuel economy is underpinned by a comprehensive package of BlueEFFICIENCY measures as well as by this state-of-the-art engineering. In addition to the ECO start/stop function that comes as standard, these measures include the new seven-speed 7G/TRONIC PLUS automatic transmission with a new fuel-economy converter, friction-optimised bearings and a transmission oil thermal management system. Low-friction axle drives, electric steering, the optimised belt drive with decoupler, the on-demand control of all ancillary components and pumps, and tyres with low rolling resistance also play their part in reducing fuel consumption. What's more, intelligent lightweight design has stopped the weight from spiralling upwards.
With a drag coefficient, or cd figure, of 0.32, the new M-Class (ML 250 BlueTEC) also sets a new best figure for this vehicle class. Intensive simulations undertaken with the digital prototype, along with final touches added in the wind tunnel, ensure a perfect flow of air around the vehicle. The key factor determining the low wind resistance is the aerodynamic efficiency of the basic body shell, including the optimised design of the front bumper, of the A-pillars and of the roof spoiler, plus numerous other detailed improvements.
The result: a high level of comfort and outstanding driving dynamics on and off the road
Even the standard version of the new M-Class offers a high level of comfort, dynamic on-road handling and outstanding off-road capabilities. For the first time, the M-Class chassis with steel suspension features selective damping. The driver is assisted by electric steering, which ensures the optimum level of steering assistance for the current driving situation. In addition to this, the SUV impresses with the smallest turning circle in its market segment.
For driving off the beaten track, the ML 350 BlueTEC 4MATIC and ML 350 4MATIC BlueEFFICIENCY models are equipped with extensive off-road features as standard, including 4MATIC permanent all-wheel drive, 4ETS electronic traction control and an off-road button which activates a special off‑road driving mode. Furthermore, the start-off assist system makes hill starts easier, while the Downhill Speed Regulation (DSR) automatically keeps the M‑Class at the speed set using the cruise control stalk.
The optional ON&OFFROAD package for the new M-Class has six driving modes for optimising driving dynamics and handling safety, as the optimum drive system control is provided for an extremely wide range of on-road and off-road operating conditions. The driver can select from one automatic mode, two special off-road modes and three on-road modes using a rotary control in the centre console. In terms of "hardware", the ON&OFFROAD package comprises an underguard, a two-stage transfer case with reduction gear, an inter-axle differential lock and enhanced AIRMATIC functionality that allows a maximum ground clearance of 285 millimetres as well as a fording depth of 600 millimetres.
Active roll stabilisation in the form of the ACTIVE CURVE SYSTEM can be optionally combined with both the AIRMATIC air suspension with Adaptive Damping System (ADS) and the ON&OFFROAD package. This system uses active anti-roll bars on the front and rear axles and compensates for the roll angle of the body through bends, increasing agility and driving pleasure in the process. The system has the additional effect of increasing handing stability and therefore safety, particularly at higher speeds. Further benefits of the ACTIVE CURVE SYSTEM include superb ride comfort both when cornering and driving in a straight line, together with enhanced off-road abilities.
Gently does it: attention to detail ensures comfort
The new M-Class promises relaxed and, therefore, safe driving in all possible conditions. By paying close attention to detail every step of the way, the development engineers in the Mercedes Technology Center have significantly improved what they call the NVH comfort level (Noise, Vibration, Harshness). This is an important factor contributing to the general sense of wellbeing on board, whilst also playing its part in driver-fitness safety, especially on long journeys. The basis for the high level of NVH comfort is provided by the very rigid bodyshell of the M-Class. Further improvements have also been made to the drive system and chassis. This is all topped off by aero-acoustic refinements and the intelligent use of new-style insulation.
Well thought-out: safety at its best
In line with the Mercedes-Benz brand philosophy, the new M-Class represents the embodiment of the Mercedes-Benz holistic safety concept of Real Life Safety, which is derived primarily from what happens in a real accident situation. The extremely robust occupant compartment of the M-Class, together with the front and rear deformation zones, forms an effective basis for the occupant protection system. Up to nine airbags, activated on demand in accordance with the accident type and accident severity, can reduce the loads exerted on the occupants. In addition to active safety systems such as the standard-fit Brake Assist (BAS) or the optional BAS PLUS, which can help to prevent an accident or reduce the severity of an accident, the new M-Class features further enhanced passive-safety measures to help protect pedestrians, including an Active Bonnet as standard.
Both active safety and driver-fitness safety in the new M-Class are further improved by assistance systems that will already be familiar, primarily from the S- and E-Class. The standard equipment package includes the drowsiness detection system ATTENTION ASSIST, the anticipatory safety system PRE‑SAFE® and a tyre pressure loss warning system, as well as adaptive brake lights and Brake Assist (BAS). Active assistance systems such as Active Lane Keeping Assist and Active Blind Spot Assist are available as additional equipment options:
Impressive credentials: the design
The new generation is instantly recognisable as an M-Class by its characteristic body design with the hallmark C-pillar shape. It combines high levels of design, appeal and ease of use to create a powerful presence. The front of the vehicle is dominated by the powerfully self-confident design of the radiator grille with its centrally positioned Mercedes star, giving it that typical M-Class look. Seen from the side, the elongated lines give formal emphasis to the on-road credentials of this vehicle, whose compact proportions are defined by a large wheelbase and short overhangs. The C-pillar that is so characteristic of this model series takes its cue from earlier generations of the M-Class and differentiates it very clearly in stylistic terms from its competitors. At the same time, the way the roof line slopes down to the rear underlines the sporty appeal of the new M-Class. No pillar is visible in the transition from the rear side window through to the rear windscreen. This, together with the similarly wrap-around effect of the two-part rear light unit with LED fibre-optic technology, and the lowered roof with its large roof spoiler, add up to an overall harmonious design. The rear bumper, which features an integrated chrome-effect load sill guard in a new "wing design", defines the characteristic appearance of the SUV's rear end. The available wheels range from light and aerodynamically optimised 43.2 cm (17-inch) wheels through to 50.8 cm (20‑inch) wheels with an elegant, high-quality appeal. As an option, 53.3 cm (21‑inch) AMG wheels can be fitted to emphasise the sporty look of the new M‑Class.
Upgrade as standard: interior with a first-class ambience
The interior design concept clearly combines an authentic SUV experience with a sense of wellbeing that is usually the reserve of top-class Mercedes-Benz saloons. While an expressive dome shape embodies the power of an SUV, the gently sloping contours of the dashboard in the front passenger area afford an outstanding sense of space, thereby highlighting the vehicle's suitability for long journeys. The spacious, bright interior offers substantially more elbow room than its predecessor (an extra 34 millimetres in the front and an extra 25 millimetres in the rear), thus enhancing spaciousness. Eye-catching features on the dashboard include a large trim element that matches the trim used for the doors and therefore creates a harmonious wrap-around effect. The seats in the new M-Class have been designed to offer high long-distance comfort and optimum lateral support. All of the key settings can be adjusted electrically. New features include rear seat backrests adjustable for angle and the through-loading feature via the armrest for transporting skis. Folding both backrests as well as the seat cushions forward creates a level load compartment with a capacity of 2010 litres up to the roof lining – a record in this segment.
The new M-Class comes as standard with the Audio 20 CD system, which comprises a radio with twin-tuner, a colour display with a 14.7 cm screen diagonal, an MP3/WMA/AAC-compatible CD player, a USB interface with CD Cover Art display (if saved on the storage medium), an AUX-IN socket in the centre armrest and a telephone keypad. The Bluetooth interface also allows hands-free telephony and Audio Streaming for the transfer of music.One of the particularly interesting features on offer is the Becker® MAP PILOT, a fully integrated navigation module with a 2-D/3-D map display for Europe. The device is housed in a cradle in the glove compartment and is operated using the central controller for the Audio 20 CD system. The COMAND Online multimedia system with a high-resolution 17.8 cm colour display provides internet access in the M-Class for the first time. Customers can either browse freely when the vehicle is at a standstill or use a Mercedes-Benz App with pages that load extremely quickly and are also easy to use when the vehicle is on the move. As an option, COMAND Online is available with a 6-disc DVD‑changer. This system's standard features include Speed Limit Assist, which recognises traffic signs and displays them in the instrument cluster.
The new SLK 250 CDI
Sports car performance with the fuel economy of a sub-compact
For the first time, Mercedes-Benz is offering the sporty SLK Roadster with a diesel engine. The 150 kW (204 hp) four-cylinder power unit puts the two-seater at the top of its class in numerous respects. With a fuel conÂsumption of 4.9 litres per 100 kilometres, it is the most economical roadster in its segment. Thanks to its enormous torque of 500 newton metres it accelerates from zero to 100 km/h in 6.7 seconds, and delivers a top figure for acceleration from 80 to 120 km/h. The result is superior driving enjoyment both on winding country roads and on long motorway stretches. Like the other models in the latest SLK family, which was presented in January this year, it combines lively sportiness with high-quality appointments and excellent comfort.
Diesel drive and roadster excitement do not go together – or so a common misconception would have it. Mercedes-Benz impressively demonstrates the contrary with the new SLK 250 CDI. Its four-cylinder diesel engine with a displacement of 2143 cc generates an output of 150 kW (204 hp) and 500 newton metres of torque – as much as a petrol engine with twice the displacement would normally generate. This makes the new SLK 250 CDI the most powerful diesel model in its class, and gives the roadster the potential for extremely sporty performance.
Equipped with the standard 7G-TRONIC PLUS automatic transmission (a six-speed manual transmission will follow in the second quarter of next year), the diesel SLK sprints from zero to 100km/h in 6.7 seconds and achieves a top speed of 243 km/h. Moreover, the flexibility of the SLK 250 CDI is nothing short of phenomenal. Thanks to its enormous diesel torque it accelerates from 80 to 120 km/h in just 4.3 seconds – easily the best figure in this class, making for safe and effortless overtaking. Apart from this, the SLK 250 CDI is the most economical and therefore environmentally compatible roadster in its segment. It is happy with 4.9 litres of diesel fuel per 100 kilometres (NEDC combined consumption), which corresponds to CO2 emissions of 128 g/km. In other words, the diesel SLK combines thoroughbred sports car performance with the fuel economy of a sub-compact. This guarantees great driving pleasure with great fuel efficiency.
The diesel engine achieves its exemplary output, torque, fuel consumption and emissions figures, as well as its highly impressive smoothness for a diesel unit, thanks to an extensive package of innovative technologies. These include fourth-generation common-rail injection with a rail pressure of 2000 bar and precise injection timing, as well as two-stage turbocharging. Like all SLK models, the SLK 250 CDI also features a start/stop system as standard.
The frugal fuel consumption makes the SLK 250 CDI a car with superior long-distance qualities. Using the European motorways, it is e.g. quite possible to drive from the North Sea to a beach on the Mediterranean non-stop. Very comfortable sports seats, a comfortable suspension setup and the largest luggage capacity in this segment also do their bit to create the right conditions.
As it shares the same genes with the other members of the successful SLK family, the SLK 250 CDI combines lightfooted sportiness with stylish comfort, a striking sports car design and absolute day-to-day suitability, while delivering top performance with exemplary ecology. This means that the diesel version too provides open-top driving enjoyment at an extraordinarily high level.
The SLK 250 CDI is likewise available with a choice of three versions of the famous vario-roof – one of them the panoramic vario-roof with MAGIC SKY CONTROL. This glass roof can be changedark to transparent at the touch of a button. There are also three suspension versions available: a conventional steel suspension, a sports suspension with a stiffer spring and damper setup or a suspension with an electronically controlled, fully automatic damping system. The latter is part of the Dynamic Handling package, which also includes the Direct-Steer system and the Torque Vectoring Brake developed by Mercedes-Benz for particularly agile and predictable handling characteristics.
Externally the new SLK 250 CDI is no different in appearance from the petrol models. It even retains the twin exhaust system, and therefore has the same exciting look for which all the SLK models are known. The new SLK 250 CDI can be ordered from 13 September 2011. The price including VAT is € 41,828.50.
Luxury van Viano Vision Pearl
Yacht on four wheels
With the Viano Vision Pearl showcar, which will be presented at this year's International Motor Show (IAA), Mercedes-Benz demonstrates what is possible in the van sector. A full leather interior in white/grey, wood floor, brushed aluminium trim, chromatically tinting windows and the Bang &Olufsen high-end sound system "BeoSound Viano" make a journey in the Viano Vision Pearl a memorable experience for up to six occupants. The generous interior has space for the very latest technologies and exclusive design features.
The design concept takes its inspiration from that of modern sporting yachts, with the theme of travel as an experience. The onboard W-LAN connectivity caters for the needs of modern, mobile individuals. For the exterior design, Mercedes-Benz has for the first time in the MPV sector used the paint finish "magno pearl grey", a matt, pebble-grey colour. The stylistically revised front end of the Viano with its integrated LED daytime running lamps gives the van a more sporty, powerful appearance.
The way is the goal: driving experience meeting the highest expectations
Mobility is nowadays more experience-oriented. Most people no longer travel somewhere just to relax and enjoy themselves. Car or motorcycle tours, cruises, sailing trips or trekÂking Âtours – the travelling time itself becomes part of the experience. Mercedes-Benz reflects this trend with the Viano Vision Pearl. "We want to show what can be done with the Viano. The Viano Vision Pearl is not merely a functional van, but also a stylishly designed living space," says Volker Mornhinweg, Head of Mercedes-Benz Vans. "We have created a vehicle which combines generous spaciousness with an impressive design. Anybody who attaches importance to stress-free and at the same time stylish travel will find that the Viano Vision Pearl is the ideal companion. The interior design and technical features make the Viano Vision Pearl the S-Class among vans."
Impressive listening experience with Bang & Olufsen "BeoSound Viano" high-end sound system
The Viano Vision Pearl is rounded off by the Bang & Olufsen sound system. Mercedes-Benz has worked together with this world-renowned manufacturer of audio systems since 2009, and integrates the high-end sound systems into passenger cars such as the S-Class.
Thanks to the very high output of 1320 watts and 18 integrated, specially hand-built loudspeakers, the vehicle occupants are treated to an outstanding listening experience.
The Viano Vision Pearl is stylishly discreet where the outside world is concerned: as the loudspeakers are located in their own housings, very little sound volume escapes to the outside.
Mercedes Concept A-CLASS
The first heartbeat of a new generation
In 1993 Mercedes-Benz ventured into a completely new vehicle class with the revolutionary concept of the Vision A 93. Now the brand is once again presenting a car that might have come from another planet: the Mercedes Concept A-CLASS is the first heartbeat of a new generation whose expressive design stands for concentrated dynamism. The technical highlights of this front-wheel drive concept car include a new, turbocharged four-cylinder petrol engine developing 155 kW (210 hp), a dual clutch transmission and a radar-based collision warning system with adaptive Brake Assist.
A long bonnet, low silhouette and slim window areas: the proportions of the Concept A-CLASS stand for concentrated dynamism. Its sporty appearance is given particular depth by the interplay between lines and surfaces. "The Concept A-CLASS introduces the new Mercedes-Benz design idiom into the compact class in a sculptured, light and expressive interpretation," says Professor Gorden Wagener, Head of Design at Mercedes-Benz. "We use the term 'captured energy' to express the sheer dynamism exuded by the Concept A-CLASS. Our formal sources of inspiration were the wind and waves, as well as aviation engineering, resulting in this "cool" look."
New turbocharged petrol engine, seven-speed dual clutch transmission
But it is not only visually, but also technologically that the Concept A-CLASS is ushering in a new compact class era at Mercedes-Benz. This front-wheel drive model is powered by a four-cylinder petrol engine from the new M270 series. It was designed for transverse installation, and thanks to direct injection and turbocharging it offers a high performance potential together with minimal emissions and fuel consumption. Other highlights of the all-aluminium engine include injection pressures of up to 200 bar and fast-responding piezo injectors.
The Concept A-CLASS is equipped with the two-litre variant of the new engine, developing 155 kW (210 hp). This BlueEFFICIENCY unit is combined with the new Mercedes-Benz dual clutch transmission. As a three-shaft transmission, this has seven forward gears which are shifted automatically with no interruption in tractive power. The new transmission is therefore particularly economical, sporty and comfortable.
Exterior design with defined edges and a free interplay with the body surfaces
One major characteristic of the new design idiom at Mercedes-Benz is the expressive interplay between lines and surfaces – which the designers refer to as a "clean" concept. Thanks to concave and convex surfaces with the resulting light modulation, this creates a unique sculpture-like presence. The Concept A‑CLASS emphatically continues this theme of defined edges and interacting surfaces, which Mercedes-Benz first showed in the F 800 Style. The side view is structured by three prominent lines: the front structural edge forms a dropping line towards the rear, while the pronounced shoulder muscle over the rear axle emphasises the car's coupé-like character. A further line extends upwards in front of the rear wheel arch in a sweeping curve. These lines lend more depth and dynamism to the side profile. The door handles are recessed into the doors, and emerge electrically at the touch of a button.
The unusual, wing-like structure of the exterior mirrors is suggestive of flow and lightness. Another prominent feature is the open side skirt, which creates an unusual light-and-shadow effect. Reminiscent of a turbine rotor, the large 20-inch wheels reinforce the impression that the Concept A-CLASS has been shaped by the wind.
The front end of the Concept A-CLASS is a real eye-catcher. The brand logo appears to be surrounded by a starry sky. Where there are usually apertures or louvres, the radiator grille consists of numerous metallic silver "dots" on black stems. This theme is reflected in the design of the wheels.
The visually wide rear end exudes power and athleticism, and is likewise enlivened by an interplay between convex/concave surfaces and pronounced edges. The tail light clusters continue the lines of the muscular shoulders towards the rear, emphasising the car's width with their horizontal orientation. The aerodynamic spoiler lip in the tail lights improves efficiency, while the diffuser creates a downforce to aid roadholding.
Interior dominated by associations with aviation engineering
The interior of the Concept A-CLASS, which is flooded with light from the large panoramic roof, likewise appears to be from another planet. Many of the unusual features were inspired by aircraft engineering, at the same time reflecting ideas from the "Mercedes-Benz Aesthetics No. 2" interior sculpture. Various component groups have been reduced to a minimum, for example the dashboard and centre console are merely brushed aluminium structures. The result is a transparent, light, bionic design effect.
As an extremely eye-catching detail inside the Concept A-CLASS, the dashboard takes the form of an aircraft wing and has a translucent, stretchable textile lining. Thanks to this sophisticated fabric, which is vapour-coated with chrome particles, the bionic cellular structure of the dashboard remains visible – its design is reminiscent of a canvas-covered aircraft wing whose underlying struts are discernable. Dramatic backlighting makes this instrument carrier appear particularly futuristic. Thanks to the translucent high-tech lining and lack of a conventional support structure, the dashboard appears to be free-floating. Its lines continue into the door panelling like vapour trails from the winglets of a jet.
The form of the air vents in the dashboard is likewise inspired by the engines of a jet aircraft. The translucent, backlit vents change their colour depending on the temperature the occupants have selected for the climate control system: they are blue if cool, fresh air is vented into the interior, but red if the airflow is heated. The prominent displays in the instrument cluster, which were inspired by the afterburner of a jet engine, are likewise in red. The central control unit is designed as a high-tech flight panel with a shift lever in the shape of a "thrust control". With their moulded-over head restraints and very pronounced lateral support, the seats call the pilot seat in a jet fighter to mind.
Titanium and silver tones are combined with a light, elegant beige in the interior. Magenta is used to produce highlights that contrast with the car's alubeam silver paint finish, which follows the dynamic contours of the exterior like liquid silver.
The Concept A-CLASS makes use of modern materials such as the high-tech lining on the dashboard, or metallised leather where semi-aniline is dyed with metallic pigments and embossed, and also high-grade nubuk leather. This builds a bridge between 125-year tradition of the Mercedes-Benz brand and its claim to progressiveness.

A smartphone is fully integrated into the operating systems of the Concept A‑CLASS. When the phone is inserted into the recess provided in the centre console, it is automatically synchronised with the COMAND multimedia system. All the functions of the smartphone, including internet radio, email and social networks such as Twitter or Facebook, are shown as applications on the 17.8 cm display and can be operated via the rotary/push control.
The visual presentation of the screen elements is unique, with a deep, three-dimensional look created by laser-like, magenta-coloured lines. This near-series display concept was designed and realised by designers and engineers at the Mercedes-Benz development laboratory in Palo Alto, USA. The menus in the Concept A-CLASS are in both Mandarin and English.
Headlamps with optical fibres produce a unique effect
A very special effect is created by the lights of the Concept A-CLASS, as the innovative full-LED high-performance headlamps repeat the starry sky motif of the radiator grille with numerous lighting points. The daytime running lamps consist of 90 optical fibres with aluminium sleeves, and they are arranged in a wing-shape within the headlamp. The tentacle-like fibres form individual, diffused light sources to create a dramatic contrast between soft and harsh.
From any perspective an unusual effect is also created by the LED indicators, which appear to float freely within the headlamps like an enclosed air bubble in a perfume bottle. The indicators are mounted in six chambers at the top of the perspex headlamp unit, and their vapour-coated reflectors remain invisible.
As already brought to series production maturity in the Mercedes CLS, the LED high-performance headlamps of the Concept A-CLASS combine the Intelligent Light System with LED technology. The projection module of these LED headlamps is no longer round, but rather flatter and sportier. This sporty impression is reinforced by the matt carbon-fibre housing, which contrasts with the aluminium surround of the projection module.
Optical fibres with aluminium sleeves are also used in the tail lights. 120 optical fibre lighting points form each C-shaped tail light cluster to create a unique visual effect with their subtle glow. They are appropriately lit up for the brake light function. When braking, the continuous light band between the two tail light clusters also lights up to make the Concept A-CLASS appear even wider. The indicators are self-contained elements in the centre of the tail lights. The base unit of the tail light is of carbon-fibre, with the numerous red elements ensuring visual depth.
New assistance and braking system reduces the risk of rear-end collisions
In the Concept A-CLASS, safety pioneer Mercedes-Benz is showing another milestone in the democratisation of automotive safety technology: the concept car is equipped with a radar-based collision warning system with adaptive Brake Assist – a world first in the compact class. This system gives a visual and acoustic warning to a possibly inattentive driver, and prepares Brake Assist for an absolutely precise braking response which is initiated as soon as the driver emphatically operates the brake pedal.
In contrast to other systems available in the market for the compact class, the new Brake Assist COLLISION PREVENTION ASSIST is not merely an urban driving system designed to minimise the effects of minor collisions. Instead this innovative solution aims to provide protection against typical rear-end collisions in all driving situations. Mercedes-Benz expects the new safety system to have a significant, positive effect on accident statistics. Following detailed analyses of accident data, Mercedes-Benz safety specialists estimate that this radar-based technology can help to prevent around 20 percent of all rear-end collisions, and mitigate the severity of a further 25 percent.
The Mercedes-Benz SLS AMG Roadster
Open sensuality: roadster performance in its perfect form
The performance brand within Mercedes-Benz Cars is presenting a new dream-car: the SLS AMG Roadster. This super sports car thrills with a perfect synthesis of open-top driving pleasure, outstanding driving dynamics and systematic lightweight construction. The overall visual appearance of the new two-seater is marked by its purist design.
The technological highlights of the SLS AMG Roadster read like an A-B-C of modern sports car engineering: the combination of an aluminium spaceframe body, an AMG 6.3-litre V8 front-mid engine with dry sump lubrication developing a peak output of 420 kW (571 hp) and 650 newton metres of torque, a seven-speed dual clutch transmission in a transaxle arrangement and a sports suspension with aluminium double wishbones is guaranteed to make the hearts of sports car enthusiasts beat faster – while ensuring outstanding driving dynamics and roadster motoring pleasure.
The compact fabric soft top of the SLS AMG Roadster opens and closes in just eleven seconds, and can be operated on the move at speeds up to 50 km/h. The new AMG RIDE CONTROL sports suspension with electronically controlled damping is available as an attractive optional extra. It enables the damping characteristics to be modified at the touch of a button. Using the AMG DRIVE UNIT, the driver of the SLS AMG Roadster is therefore able to choose his own suspension setup. Three modes are available: "Comfort", "Sport" and "Sport plus".
"AMG Performance Media" is a unique new feature: this innovative multimedia system inspired by motorsport offers an unrivalled combination of numerous telemetric displays such as lateral and linear acceleration, various engine data and lap times on a racetrack, and also features high-speed mobile internet access.
Dr Dieter Zetsche, Chairman of the Board of Management of Daimler AG and CEO of Mercedes-Benz Cars: "The SLS Roadster is a super sports car, cruiser and highly desirable dream-car all in one. It its distinctive way, it continues the succession of iconic and exciting sports cars from Mercedes-Benz."
Ola KÃ¤llenius, Chairman of Mercedes-AMG GmbH: "Systematic lightweight construction, outstanding performance and a breathtaking design combined with sensuous open-air driving pleasure – the new SLS AMG Roadster perfectly embodies the AMG philosophy of German engineering and craftsmanship. The gull-wing model has already thrilled sports car fans all over the world, and now the open-top version is bound to cause a sensation."
Purist roadster design with perfect proportions
The new Roadster adds a second exciting dream-car to the AMG model family. Head of Design at Mercedes-Benz, Gorden Wagener: "As in the gull-wing model, the purist, athletic design immediately captures the attention. Whether with the roof open or closed, the SLS AMG Roadster is an impressive visual delight!" The perfect proportions are particularly memorable: a long bonnet, the greenhouse positioned well to the rear and a short rear end. Plus the automatically extending rear aerofoil, long wheelbase, wide track and short overhangs – in short, the open-top SLS AMG likewise exudes effortless dynamism and an authentic charisma. The pronounced shoulder sections are reminiscent of tensed muscles, and suggest sheer power in combination with the large wheels in size 265/35 ZR 19 (front) and 295/30 ZR 20 (rear). The attractive metallic paint finish AMG Sepang brown and weight-optimised forged wheels in a 10-spoke design, painted in matt black with a high-sheen rim flange, are available as new optional extras.
Features reminiscent of the 300 SL Roadster, the classic dream-car from the 1950s, include not only the wide radiator grille with its large Mercedes star and the wing-shaped cross-fin, but also the fins on the bonnet and on the vehicle flanks. Like the SLS AMG Roadster, the 300 SL Roadster appeared slightly later than the original gull-wing 300 SL, but unlike in the former case both AMG dream cars are available at the same time.
Interior atmosphere as in an aircraft cockpit
The interior continues the breathtaking design idiom of the exterior, and awakens associations with an aircraft cockpit: prominent stylistic features include the dashboard in the shape of a wing section and the air vents with adjustable, cruciform nozzles reminiscent of jet engines. The extended centre console of matt, solid metal and the new E-SELECT lever in the shape of an aircraft's thrust control are also design features adopted from the world of aviation. Another discreet, fine detail is the embossed AMG emblem on the leather-lined selector lever.
The AMG DRIVE UNIT – which like numerous other interior features is available in real carbon-fibre – is the central control unit in the centre console: it allows the driver to choose a personal vehicle setup, including adjustment of the AMG RIDE CONTROL sports suspension (optional). The AMG Performance steering wheel with its high-grade nappa leather lining and flattened lower rim section allows perfect vehicle control. The shift paddles and lower steering wheel bezel are of solid metal.
Fully automatic, weight-optimised soft top
The sensual experience in the SLS AMG Roadster is enhanced further when the soft top is open, and the powerful, naturally aspirated eight-cylinder engine with 420 kW (571 hp) and 650 newton metres of torque asserts itself and makes the heart beat faster with its typical AMG eight-cylinder sound. The fabric soft top can be opened and closed while on the move at up to 50 km/h; the fully automatic opening/closing process takes only eleven seconds. The driver only needs to operate the roof control unit conveniently integrated at the front of the centre armrest. When open, the soft top is space-savingly deposited behind the seats in a folded Z-configuration. Three soft top colours – black, red and beige – are available to suit the nine exterior and eight interior colours.
The three-layered fabric soft top is a weight-optimised magnesium/steel/ aluminium construction, and contributes greatly to the car's low centre of gravity. The soft top has a seamlessly bonded rear window of heated single-layer safety glass. The flush, gap-free transition between the outer roof skin and the rear window keeps wind noise at a low level. A continuous, flexible water pocket running under the soft top catches rainwater and directs it to the underbody via two apertures on each side. The boot capacity is 173 litres with the roof either open or closed, and therefore roughly equal to that of the SLS AMG Coupé (176 litres).
Outstanding material quality and standard of finish
The finest leather, matt-finished solid metal or optional, real carbon-fibre trim create an exclusive ambience and correspond with the authentic feel of the cockpit. Precisely executed decorative and contrasting stitching enhances the visual impression, heightens the hand-crafted look and reflects the attention to detail which is the hallmark of Mercedes design.
The standard appointments of the SLS AMG Roadster include black designo leather, AMG sports seats with heating, a slot-in glass draught-stop, COMAND APS with DVD player, anti-theft alarm system with tow-away protection and interior monitoring, THERMOTRONIC luxury automatic climate control and the KEYLESS-GO starting function. The optionally available AIRSCARF® system exclusive to Mercedes-Benz acts like an invisible scarf warming the head and neck areas of the occupants. It is integrated into the backrests of the AMG sports seats, and blows warm air from vents in the head restraints. The airflow can be adapted for different occupant sizes by means of adjustable louvres, and the level of warmth can be selected in three stages at the touch of a button.
Leather-lined roll-over bars with integrated mesh in a "Silver Shadow" look are available in conjunction with the optional designo Exclusive leather to reduce turbulence in the cockpit. Ambient lighting is integrated into the optionally available, electrically folding exterior mirrors.
Single-tone or two-tone designo leather in espresso brown is available as a new interior colour – this dark shade of brown perfectly matches the new metallic paint finish AMG Sepang brown.
AMG Performance Media and Bang & Olufsen as optional highlights
Another optional highlight is available in addition to the Bang & Olufsen BeoSound AMG surround sound system, which provides exclusive musical enjoyment at the highest level: AMG Performance Media. In an unprecedented way, this system inspired by motor racing combines numerous telemetric displays such as engine data, lateral and linear acceleration and lap times on a racetrack, as well as providing high-speed mobile internet access. AMG Performance Media is activated by pressing the AMG key in the AMG DRIVE UNIT, and operated using the COMAND Controller. Key functions at a glance:
The different functions of AMG Performance Media are shown by the colour display integrated into the dashboard. Three displays are shown at any one time, with the most important information positioned in the centre. Digitally simulated dial instruments with red needles ensure outstanding legibility.
High-speed mobile internet access
AMG Performance Media also provides high-speed mobile internet access: when the car is stationary, the driver and passenger are able to surf the web, download and install apps, and send or receive emails – this unrivalled system has functions comparable to those of a PC, notebook or smartphone. AMG Performance Media uses the widespread, high-performance Android operating system. This exclusive new development will also be installed in other AMG high-performance cars in the future.
Specifically reinforced aluminium spaceframe, low DIN kerb weight
In addition to a high level of occupant comfort, the key factor for driving pleasure in the new SLS AMG Roadster is of course the outstanding performance. The basis for this is the innovative body design: the chassis and body are of aluminium, a design combining intelligent lightweight construction with high strength. With a DIN kerb weight of 1660 kilograms, the Roadster is only 40 kilograms heavier than the Coupé. The result is a remarkable power-to-weight ratio of 2.9 kilograms per hp.
To achieve the same level of driving dynamics despite the lack of a fixed roof, the SLS AMG Roadster has features specifically designed to rigidify the bodyshell, for example side skirts with greater wall thicknesses and more chambers. The dashboard cross-member is supported against the windscreen frame and centre tunnel by additional struts, and a curved strut between the soft top and the tank reinforces the rear axle. The omission of the Coupé roof and gull-wing doors means that the open-top SLS AMG has a reinforcing cross-member behind the seats to support the fixed roll-over protection system. This also accommodates the 250 watt subwoofer of the Bang & Olufsen BeoSound AMG high-end sound system.
All this prevents unwanted vibrations right from the start, and makes it unnecessary to use the additional, weight-increasing vibration dampers that are often found in open-top sports cars. The weight-optimised aluminium spaceframe weighs 243 kilograms, tipping the scales at just two kilograms more than the gull-wing model.
Intelligent material mix and low centre of gravity
50 percent of the intelligently designed, weight-optimised aluminium spaceframe is of aluminium sections, 26 percent of sheet aluminium, 18 percent of cast aluminium and 6 percent of steel. Maximum occupant safety requires the use of ultra-high-strength, heat-formed steel in the A-pillars.
The entire vehicle concept has been designed to achieve the lowest possible centre of gravity. This applies both to the low connection of the powertrain and axles, as well as to the arrangement of the rigidity-conducive bodyshell structure, which has been kept as low as possible. Examples include the rigid flexural and torsional connections between the front and rear section and the safety passenger cell, which have been realised consistently using force paths that are as low as possible. This results not only in a low centre of gravity but also in a harmonious and therefore efficient force path in the vehicle structure.
Passive safety at a high level
The aluminium spaceframe provides the basis for outstanding passive safety. The extensive safety features include the fixed roll-over protection system, three-point seat belts with belt tensioners and belt force limiters, and eight airbags: adaptive front airbags and kneebags, two seat-integrated sidebags and two windowbags deploying from the door beltlines.
The optionally available Blind Spot Assist helps the driver with a visual warning symbol and acoustic alert if the danger of a collision with another vehicle is detected when changing lanes.
Powerful AMG 6.3-litre V8 engine with 420 kW (571 hp)
The SLS AMG Roadster has the same, muscular engine as the gull-wing model. The 6.3-litre V8 with a peak output of 420 kW (571 hp) at 6800 rpm makes the open-top SLS one of the most powerful sports cars in its segment. Its power-to-weight ratio is 2.9 kg/hp. This naturally aspirated engine generates its maximum torque of 650 newton metres at 4750 rpm. The open-top SLS AMG accelerates from zero to 100 km/h in 3.8 seconds, and the top speed is 317 km/h (electronically limited) – which means that the Roadster has a performance comparable to the gull-wing variant.
The high-revving V8 engine with a cubic capacity of 6208 cc has the typical characteristics of powerful racing engines. It responds immediately to accelerator movements and is extraordinarily willing. The use of a dry sump lubrication system makes for a considerably lower installed position in the vehicle. The resulting, lower centre of gravity allows high lateral acceleration and ensures thrilling driving dynamics.
Achievement of demanding fuel consumption targets
Despite its uncompromisingly sporty character, very ambitious fuel consumption targets have been met. The SLS AMG consumes 13.2 litres per 100 kilometres (NEDC combined), corresponding to CO2emissions of 308 grams per kilometre. Efficiency-enhancing measures include the familiar AMG-exclusive, friction-optimised twin-wire arc-sprayed coating on the cylinder walls as well as the on-demand, map-optimised oil supply and intelligent generator management: during the engine's overrun phases, kinetic energy is used to charge the battery rather than being wasted by simply generating heat. Conversely, the generator is switched to no-load operation during acceleration, thus reducing the load on the engine. Sophisticated catalytic converter technology enables current and future emission standards such as Euro-5, LEV 2 and ULEV to be met.
Double-clutch transmission with transaxle configuration and torque tube
The AMG 6.3-litre V8 engine delivers its abundant power to the rear axle via an ultra-light carbon-fibre driveshaft – similar to the setup used in the DTM C‑Class racing touring car. The double-clutch transmission is mounted at the rear (transaxle principle), and connected to the engine housing via a torque tube. A carbon-fibre shaft rotates at engine speed in the torque tube. The advantages of this sophisticated solution lie in the rigid link between the engine and transmission and, in turn, the optimum support for the forces and torque generated.
The AMG SPEEDSHIFT DCT 7-speed sports transmission boasts fast gear changes with no loss of tractive force – in as little as 100 milliseconds. The driver has a choice of four different driving modes: "C" (Controlled Efficiency), "S" (Sport), "S+" (Sport plus) or "M" (Manual). In the Sport, Sport plus and Manual modes the automatic double-declutching function is active; all the modes can be selected conveniently via the rotary control in the AMG DRIVE UNIT. The RACE START function provides optimum traction -- as does the mechanical differential lock, which is integrated into the compact transmission housing.
Sophisticated suspension layout with double-wishbone axles
The chosen solution with a front-mid-engine plus transaxle configuration ensures an ideal front/rear weight distribution of 47 to 53 percent. Mounting the engine behind the front axle has created the ideal conditions for consummate driving dynamics with precise steering, first-class agility, low inertia with spontaneous directional changes and outstanding traction. All four wheels are located on double wishbones with a track rod, a technology that has proven itself in motor racing right through to Formula 1. With a double-wishbone axle, the wheel location and suspension functions remain separate; the spring/ damper struts are supported on the lower wishbone. The double-wishbone concept with its high camber and track rigidity positively locates the wheel with minimal elastic movements, providing the driver with an optimum sense of road contact when driving at the limits.
Wishbones, steering knuckles and hub carriers at the front and rear are made entirely from forged aluminium – substantially reducing the unsprung masses; this configuration also notably improves the suspension response. The long wheelbase of 2680 millimetres not only results in outstanding straight-line stability but also low wheel load shifts, significantly reducing the vehicle's tendency to dive and squat when braking and accelerating. The broad track width – front 1682, rear 1653 millimetres – ensures lower shifts in the wheel loads from the inner to the outer wheel when cornering, enabling the tyres to retain more grip.
New AMG RIDE CONTROL sports suspension on request
The new AMG RIDE CONTROL sports suspension with electronically controlled damping is available as an attractive optional alternative to the AMG sports suspension. It enables the damping characteristics to be modified at the touch of a button. Using a button in the AMG DRIVE UNIT, the driver of the SLS AMG Roadster is therefore able to choose his own suspension setup. Three modes are available: "Comfort", "Sport" and "Sport plus". The current mode is shown in the instrument cluster.
"Comfort" delivers a sensitive response with soft damping characteristics, while in "Sport" mode the shock absorbers have a much stiffer response depending on the driving situation. This not leads to better road contact, but also effectively suppresses body roll and pitching. "Sport plus" is ideal for challenging laps on a racetrack: in addition to the higher damping force, this mode comes with specific control algorithms that have been tailor-made for a decidedly sporty driving style on level road surfaces. The new, variable suspension will also be optionally available for the SLS AMG Coupé in future.
Direct steering, differential lock and 3-stage ESP®
The rack-and-pinion steering gear provides a consistently direct steering feel with a constant mechanical ratio of 13.6:1, in tune with the high expectations placed on a super sports car. The power steering provides speed-sensitive assistance and improves feedback for the driver as the road speed increases: an indispensable factor for high-speed straight-line driving. Mounting the steering gear in front of the engine on the integral subframe enables the engine to be set down very low. The SLS AMG comes with 3-stage ESP® as standard, providing the driver with access to the three "ESP ON", "ESP SPORT" and "ESP OFF" modes at the touch of a button. In "ESP OFF" mode too, operating the brake pedal restores all the normal ESP® functions.
The acceleration skid control (ASR) system's traction logic is active in all three ESP® modes. If one of the drive wheels starts to spin, specific brake pressure is applied to improve traction significantly – especially in conjunction with the standard-fit mechanical multi-disc limited-slip differential. This means that the engine power is transferred to the road even more effectively when driving in a particularly dynamic style.
AMG ceramic high-performance composite braking system as an option
The AMG high-performance braking system with composite brake discs at the front ensures extremely short stopping distances even under enormous loads. From now on, red-painted brake callipers all-round are available on request. The newly developed, optional ceramic composite brakes with even larger brake discs guarantee even better braking performance. The ceramic brake discs perform reliably at even higher operating temperatures thanks to their greater hardness, all combined with an impressive weight reduction of around 40 percent. Reducing the unsprung masses has further improved both comfort and grip, and the reduced rotating masses at the front axle ensure a more direct steering response.
Lightweight construction was also key when it came to the wheels: AMG light‑alloy wheels based on the innovative flow-forming principle reduce the unsprung masses while improving driving dynamics and suspension comfort. In addition to the standard-fit AMG 7-spoke light-alloy wheels, 5-twin-spoke wheels and weight-optimised 10-spoke forged wheels are available as an option. 265/35 R 19 (front) and 295/30 R 20 (rear) tyres developed exclusively for the SLS AMG ensure optimum performance. A tyre pressure monitoring system is fitted as standard to permanently monitor tyre pressure in all four wheels, with an individual display for each tyre.
Production in Sindelfingen, market launch in autumn 2011
The SLS AMG Roadster was designed and developed in parallel with the Coupé under the autonomous aegis of Mercedes-AMG GmbH. The open-top super sports car will be produced at the largest Mercedes-Benz production plant in Sindelfingen. The AMG 6.3-litre V8 engine comes directly from the AMG engine workshop in Affalterbach, where it is hand-assembled according to the traditional "One man, one engine" philosophy.
The Mercedes-Benz SLS AMG Roadster market launch commences in autumn 2011. The selling price is € 195,160 (incl. 19% VAT).
The new SLK 55 AMG
Top marks in all disciplines
The Mercedes-Benz SLK 55 AMG is the most powerful SLK of all time. Its new AMG 5.5-litre V8 engine featuring cylinder shut-off combines the ultimate in performance with the lowest possible fuel consumption. With a peak output of 310 kW (422 hp) and maximum torque of 540 Nm, the SLK 55 AMG outperforms all of its direct competiÂtors. Its fuel consumpÂtion of 8.4 litres per 100 kilometres (combined) and CO2 emissions of 195 g/km are around 30 percent lower than those of its predecessor. High levels of driving dynamics are ensured thanks to the AMG sports suspension with Direct-Steer system, Torque Vectoring Brakes and 3‑stage ESP®, as well as the AMG high-performance braking system. A particularly appealing addition to the range is the "Edition 1".
Forming part of the third-generation of the SLK launched in March, the new top-of-the range AMG model already demonstrates its individuality even at first glance: distinctive AMG light-alloy wheels, specific AMG bodystyling with AMG spoiler lip and two chrome-plated twin tailpipes at the rear complement the classic roadster proportions, while adding a markedly athletic touch. The expressive design of the SLK 55 AMG is both eye-catching and unmistakable.
The SLK 55 AMG is the perfect embodiment of the new AMG brand claim of "Driving Performance": in the compact high-performance Roadster segment there is nothing to compare to its combination of tangible driving dynamics, superior sportiness, unique high-technology and low fuel consumption. The SLK 55 AMG accelerates from zero to 100 km/h in 4.6 seconds, and reaches a top speed of 250 km/h (electronically limited). Key figures at a glance:
|SLK 55 AMG|

* provisional figures; ** electronically limited
The world's most fuel-efficient V8 engine combines the lowest consumption figures with the superior power delivery and the typical sound experience which only a large-displacement eight-cylinder engine can provide.
In line with its "AMG Performance 2015" strategy, with the new V8 unit Mercedes-AMG is meeting its promise to continue to reduce both the fuel consumption and emissions of new models over the next few years – while reaching new heights with the central brand claim of "Driving Performance". At the same time, AMG is also demonstrating its social responsibility with the M152.
New naturally aspirated eight-cylinder closely related to the V8 biturbo
The new M152 is based on the AMG M157 5.5-litre V8 biturbo engine presented in 2010, which powers the E 63 AMG, CLS 63 AMG, S 63 AMG and CL 63 AMG. Numerous design features are identical, such as the displacement, bore/stroke, distance between cylinders, start/stop system and direct petrol injection technology. Distinguishing features versus the M157 include the new intake air ducting, new cylinder heads, the modified valve drive, an adapted oil supply system and an optimised crankcase.
Exclusive combination of advanced technologies
The high-tech M152 powerpack enthrals with a combination of advanced technologies which is unequalled anywhere in the world. No other petrol engine features direct injection at a pressure of 200 bar, spray-guided combustion and piezo injectors, all in conjunction with map-controlled cylinder shut-off, an all-aluminium crankcase with "spectacle" honing, four-valve technology with continuous camshaft adjustment, a high compression ratio of 12.6 : 1, a start/stop system and generator management – while revving to a maximum speed of over 7000 rpm. All of these measures lead to high thermodynamic efficiency, which is a precondition for high fuel efficiency and low exhaust emissions. Moreover, deciding in favour of a large-displacement, naturally-aspirated eight-cylinder unit with cylinder shut-off resolves the conflict of aims between high output/torque delivery and low fuel consumption figures.
AMG Cylinder Management
It is the AMG Cylinder Management cylinder shut-off system in particular -completely newly developed by Mercedes-AMG - that significantly improves efficiency: cylinders two, three, five and eight are cut off under partial load, which lowers fuel consumption considerably . In similar form this technology is also used in the approx. 750-hp V8 engines used in Formula 1. As efficiency also plays a major role at the pinnacle of motor racing, two or four of the eight cylinders are cut off e.g. when cornering at slow speed, in the Safety Car phases or for pit stops. With a fuel consumption of 8.4 litres per 100 km and CO2 emissions of 199 grams per kilometre (NEDC combined), the naturally-aspirated AMG V8 engine comes in at or below the level of its competitors, however these are unable to match either the output or torque of the SLK 55 AMG – and above all, they do not use large-displacement eight-
The cylinder shut-off function is available over a wide engine speed range from 800 to 3600 rpm if the driver has selected transmission mode "C" - Controlled Efficiency. The AMG main menu in the instrument cluster informs the driver whether cylinder shut-off is active, and whether the engine is currently running in four or eight-cylinder mode. No less than 230 Nm of torque is still available in four-cylinder mode – enough power to ensure plenty of acceleration in most driving situations. As soon as the driver has a need for more power and leaves the partial load range, cylinders two, three, five and eight are activated. The switch from four to eight-cylinder operation is immediate and imperceptible, leading to no loss of occupant comfort whatsoever. At an engine speed of 3600 rpm the activation process takes no more than 30 milliseconds.
Valves closed, fuel delivery and ignition deactivated
This is made possible by intelligent interaction within the highly effective engine management system, with 16 hydraulically compensating elements and a complex oil supply system in the cylinder head. The compensating elements are integrated into the cylinder head, and keep the intake and exhaust valves of cylinders two, three, five and eight closed when cylinder shut-off is active. At the same time their fuel supply and ignition are deactivated. This not only enables the load-change losses of the four deactivated cylinders to be reduced, but also increases the efficiency of the four remaining cylinders. This is because the operating point is transferred to the higher load range. The compensating elements are compact and lightweight, allowing taut valve train operation and engine speeds up to 7200 rpm.
All-aluminium crankcase with Silitec cylinder liners
The crankcase of the new AMG 5.5-litre V8 engine features a diecast all-aluminium construction. The low (dry) engine weight of just 187 kilograms is the result of uncompromising lightweight construction methods. The bearing covers for the main crankshaft bearings are of grey cast iron, and are bolted
to the crankcase, as well as on the sides, for high rigidity.
The piston rings are carbon-coated to minimise internal friction and optimise the wearing characteristics. Cast-in Silitec cylinder liners ensure low friction for the eight pistons. So-called "spectacle" honing is another measure to reduce friction and therefore fuel consumption: in this sophisticated and complex process, the cylinder liners receive their mechanical surface treatment when already bolted in place. As honing would no longer be possible with the cylinder head installed, a jig resembling spectacles is bolted to the crankcase. The cylinder liners distort as if the cylinder head were in place, and are only then given their mechanical surface treatment. As a result, any static distortion of the cylinder liners caused by tightening the cylinder head bolts can be completely eliminated.
Other measures to optimise efficiency:
The forged crankshaft of high-grade 38MnS6BY steel alloy rotates in five main bearings, has eight counterweights and has been optimised with respect to torsional rigidity, inertia, low rotating masses and a long operating life. A two‑mass viscous damper mounted at the front reliably eliminates vibrations. Each connecting rod journal on the crankshaft carries two forged, cracked connecting rods.
Four-valve technology with variable camshaft adjustment
Perfect charging of the combustion chambers is ensured by large intake and exhaust valves, of which there are four per cylinder. The exhaust valves, which are subject to high thermal loads, are hollow and sodium-cooled. Four overhead camshafts operate the 32 valves via low-maintenance, low-friction cam followers. The infinitely variable camshaft adjustment within a range of 40 degrees on the intake and exhaust sides depends on the engine load and engine speed, leading to high output and torque values. This also results in consistent idling at a low speed. Depending on the engine speed, valve overlap can be varied for the best possible fuel/air supply to the combustion chambers and efficient removal of the exhaust gases. The variable camshaft adjustment is carried out hydraulically via four pivoting actuators. These are electromagnetically actuated and controlled by the engine control unit. The camshafts are driven by three high-performance silent chains, which have considerable advantages in terms of noise comfort compared with cylinder roller chains.
Controlled Efficiency start/stop function as standard
The Controlled Efficiency start/stop function further contributes to the low fuel consumption. This system is standard equipment on the SLK 55 AMG, and active in the fuel economy transmission mode "C". Once the driver comes to a halt e.g. at a red traffic light, the V8 engine is automatically switched off. Once the brake pedal is released or the accelerator is depressed, the engine
is immediately restarted and the car is able to move off quickly. Intelligent technology guarantees a comfortable and immediate starting procedure: a crankshaft sensor which recognises the direction of rotation registers the resting position of all eight pistons. For an automatic engine start, the cylinder with the most favourable piston position receives an injection of fuel into its combustion chamber. The precise piezo-electric injectors greatly assist this process, as they make particularly fast starts possible. The M152 always starts in eight-cylinder operation.
A framed "ECO" symbol in the AMG main menu shows the driver that the Controlled Efficiency start/stop function is active. When cylinder shut-off is active, the driver is informed by the symbol "ECO4", while "ECO8" stands for eight-cylinder operation. In the two more performance-oriented driving modes "S" (Sport) and "M" (Manual), the start/stop function is always deactivated. If required, the driver can also switch it off while in "C" mode as well. In this case neither a "start/stop" nor an "ECO" symbol appears.
Generator management helps to save fuel
A generator management system makes a further contribution to fuel economy: whenever the V8 engine is on the overrun or when braking, kinetic energy is used to charge the battery rather than being wasted as heat in the usual way. In all other operating modes a combination of onboard network and generator management enables the generator to be kept at a low voltage. This reduces the load on the engine and makes for fuel savings of around 0.15 litres per 100 kilometres according to the NEDC standard, and up to 0.2 litres per 100 km in city traffic with its frequent overrun and braking phases.
New AMG sports exhaust system with integrated exhaust flaps
For the first time AMG is using a sports exhaust system featuring an exhaust flap on each side. This technology resolves the conflict of aims between an emotional sound when driving in a sporty manner and a more discreet engine note in the partial load range. The main focus of the sound design was on achieving a perfect synthesis of perceptible dynamism and the long-distance comfort that is a hallmark of Mercedes.
Each of the two rear silencers has a flap which is variably activated on a logic-controlled basis depending on the driver's power requirement and the engine speed. At low loads and engine speeds below 2000 rpm the flaps remain closed. This causes the exhaust gases to cover a longer distance and flow through an additional damping element, so that the engine sound is pleasantly subdued and irritating frequencies are effectively suppressed – resulting in a harmonious sound impression especially in four-cylinder operation when cylinder shut-off is active.
When the driver accelerates, the flaps open at an angle of 15, then 30 and up to 50 degrees so that some of the exhaust gases cover the longer, acoustically dampened distance and some the shorter distance. This produces a sonorous engine note. Under full load at higher engine speeds in eight-cylinder mode, both flaps are fully opened so that the occupants are able to enjoy the decidedly muscular sound typical of an AMG V8. In short, they are left in no doubt about the performance potential of the 310 kW (422 hp) naturally aspirated AMG eight-cylinder engine.
The two-pipe AMG sports exhaust system with two chromed twin tailpipes has a pipe diameter of 65 millimetres from the manifolds to the pre-silencer. The diameter is reduced to 60 millimetres from the pre-silencer to the rear silencers.
Effective emissions technology with new catalytic converter boxes
Low exhaust emissions, compliance with country-specific standards and a characteristic engine sound – the requirements for the exhaust system of the new, naturally aspirated AMG 5.5-litre V8 engine were manifold and complex. The SLK 55 AMG complies with the current Euro-5 emission standard, as well as meeting all the requirements of the US market (LEV-III standard, On-Board Diagnosis II).
Air gap-insulated manifolds ensure a rapid catalytic converter response. For efficiency and to save space, this concept has a tandem catalytic converter housing on each side of the vehicle: adjacent to the firewall, two thin-walled ceramic substrates are grouped into each housing. This solution makes the previous, additional underbody catalytic converters unnecessary. The two ceramic substrates differ to ensure rapid and efficient emissions control: the front one is coated with palladium, while the rear one has a bimetal coating of palladium and rhodium. One lambda sensor per row of cylinders is located in front of each catalytic converter housing, and there is a lambda diagnostic sensor between each of the two thin-walled substrates.
Highly variable: the AMG SPEEDSHIFT PLUS 7G-TRONIC
Power is transferred to the rear wheels by means of the AMG SPEEDSHIFT PLUS 7G-TRONIC automatic transmission which features three transmission modes: "Controlled Efficiency" (C), Sport (S) and Manual (M). The automatic double-declutching function when downshifting as well as the brief, precisely defined interruption of ignition and injection when upshifting under full load shorten shifting times and increase emotional appeal when adopting a sporty driving style. A double turbine torsional damper with centrifugal pendulum which adapts to engine speed helps to minimise vibrations in four-cylinder operation and enhances the impression of comfort experienced by the vehicle occupants.
Perfect combination: dynamic driving style and comfortable cruising
The AMG sports suspension with Torque Vectoring Brakes and AMG Direct-Steer system provides both impressive lateral dynamics as well as agile handling. Looking for a highly dynamic driving style or comfortable cruising? The new SLK 55 AMG is able to offer both. Independent suspension struts with stiffer spring/damper tuning, torque strut bearings on the front axle featuring higher rigidity, stiffer stabilisers all round as well as a more negative camber on the rear axle result in high cornering speeds and a low body roll in fast S‑shaped bends.
In critical cornering conditions, the Torque Vectoring Brakes produce a defined rotational movement of the vehicle about the vertical axis in fractions of seconds, through selective brake actuation at the rear wheel on the inside of the bend. This results in the SLK 55 AMG steering into the bend precisely and under full control, without any compromises where dynamism is concerned. Complementing this feature perfectly is the AMG Direct-Steer system: it enhances handling and agility compared with the standard steering, whilst also reducing the amount of physical effort required when parking. A new power steering pump helps to reduce fuel consumption. The reason behind this: the power assistance for the steering only requires energy when the driver is actually steering. In addition, the AMG Direct-Steer system has a parameter function adapted to match the AMG sports suspension. This results in optimum response from the central position, outstanding road feel and dynamic handling in all driving situations.
The AMG-exclusive 3-stage ESP® gives individual control strategies at the touch of a button: the ESP®button in the centre console allows the driver to choose between "ESP ON", "SPORT Handling Mode" and "ESP OFF". The AMG high-performance brake system has internally ventilated and perforated brake discs on all wheels, measuring 360 x 36 mm at the front and 330 x 22 mm at the rear. The system is characterised by outstanding responsiveness, short stopping distances and excellent fatigue strength.
Optional AMG Handling package for even greater driving dynamics
The optionally available AMG Handling package enhances the vehicle's sportiness even further. It comprises an AMG Performance suspension with stiffer tuning, an AMG rear axle differential lock, composite brake discs at the front and a three-spoke AMG Performance steering wheel finished in nappa leather with Alcantara® inserts in the grip areas.
Unmistakable: uniquely styled design and appointments
Classic roadster proportions with typical AMG design characteristics as well as a hint of the SLS AMG – these are the striking visual highlights of the new SLK 55 AMG. The AMG designers have complemented the exciting basic forms of the long bonnet, the greenhouse positioned well to the rear and crisp rear section with typical AMG styling at the front, sides and rear. The new AMG front apron has large air inlets and AMG-specific LED daytime driving lights. Inspired by the SLS AMG super sports car, the wide radiator grille features a large, centrally-positioned Mercedes star. In the case of the SLK 55 AMG, the slats in the radiator grille and the lower cross strut on the front apron are painted in a high-gloss black finish. Darkened clear-lens headlamps and darkened bicolour tail lamps also come as standard exclusively on the top-of-the-range V8 model. The Intelligent Light System (ILS) is also available as an optional extra.
The vent grilles with chrome-plated fins in the front wings are not only reminiscent of the SLS AMG, but also evoke memories of the famous Mercedes-Benz 300 SL Roadster from the 1950s. The "V8 AMG" lettering beneath the grilles points to the top-of-the-range eight-cylinder model from the SLK model series. AMG-specific, distinctively styled side sill panels continue the design of the front apron through to the new rear apron. With its own unique shape, black diffuser insert with three fins as well as the two chrome-plated twin tailpipes of the AMG sports exhaust system, it gives a distinctive finishing touch to the vehicle. The spoiler lip on the boot lid, painted in the vehicle body colour, reduces lift at the rear axle and thereby increases driving stability at high speeds.
Inspired by the SLS AMG: high-quality, stylish interior
Functional, stylish, high-quality: the interior design of the SLK 55 AMG is also reminiscent of its bigger brother, the SLS AMG Roadster. Associations with the super sports car are evoked courtesy of the four air vents in the style of jet engines, as well as the centre console finished in brushed aluminium. An optional addition to the centre of the dashboard is an AMG-specific analogue watch featuring an IWC design. The AMG Performance steering wheel, with its flattened top and bottom sections, also boasts metal trim, aluminium shift paddles and grip areas finished in perforated leather. The clearly-arranged AMG instrument cluster is positioned perfectly in the driver's field of vision and features four circular instruments, distinctive dials and the AMG main menu. The switch for the transmission modes C, S and M is also located in the centre console.
The AMG sports seats with individual seat upholstery layout and optimised lateral support come as standard with the upholstery combination ARTICO man-made leather/black fabric and high-quality AMG badges in the backrests. Nappa leather and Exclusive nappa leather are both available as optional extras. As in the previous model, the AIRSCARF neck-level heating system is also available as an optional extra. This creates a flow of warm air around the neck and shoulder areas of the occupants from a vent in the front of each head restraint.
Magical: the panoramic vario-roof with MAGIC SKY CONTROL
The standard vario-roof opens and closes in less than 20 seconds, transforming the open-top Roadster into a closed-top Coupé with rigid roof at the touch of a button. Alternatively, a panoramic vario-roof in tinted polycarbonate can also be chosen. The third variant is a world premiere – the panoramic vario-roof with MAGIC SKY CONTROL. This glass roof switches to light or dark as required at the press of a button. When light it is virtually transparent, offering an open-air experience even in cold weather. In its dark state the roof provides welcome shade and prevents the interior from heating up when the sun’s rays are very intense. In other words: a feel-good atmosphere at the touch of a button
The frames of the three roof variants are made of magnesium. This makes each roof around six kilograms lighter than in the previous model, giving the car a lower centre of gravity - which benefits its agility. A comfortable alternative to the standard draught-stop is the new AIRGUIDE pivoting draught-stop. It consists of pivoting transparent plastic layers which are attached to the reverse of the roll-over bars. This is the world's first draught-stop system that enables different comfort levels to be selected for two occupants, as the driver and passenger can individually pivot the units to the centre of the vehicle in a flash, thus taming turbulent air flow from the rear. The advantage: no installation or removal effort required.
More individuality: designo and the AMG Performance Studio
Designed to meet the needs of those with even more individual tastes are the optional appointments "designo leather" and "designo Exclusive leather", offering eleven single-tone and ten two-tone upholstery variants. With designo the AMG sports seats feature a specific design which distinguishes them from the standard sports seats. Available matching elements include "AMG carbon-fibre trim" and "designo trim in black piano lacquer" for the centre console. The designo Alcantara® windscreen frame, seat belts in silver or red and also five attractive paint finishes – including two matt paint finishes – round off the stylish appearance perfectly.
Other attractive optional appointments are also exclusively available for the SLK 55 AMG from the AMG Performance Studio:
For those with very special tastes: the SLK 55 AMG "Edition 1"
Similar to the C 63 AMG Coupé and CLS 63 AMG, a particularly appealing complete package is also available in the guise of the SLK 55 AMG "Edition 1". This model variant features a whole host of specially designed high-quality exterior and interior details. There are three different paint finishes to choose from: designo magno cashmere white, diamond white BRIGHT metallic and obsidian black metallic. To add that perfect touch to the overall appearance there are also multi-spoke AMG light-alloy wheels painted in matt black with a high-gloss finish on the rim flange. To match the exterior design, the interior of the Edition 1 is available exclusively in two-tone "designo Exclusive leather" in platinum white pearl. The windscreen frame in Alcantara®, AMG carbon-fibre trim, the AMG Performance steering wheel with Alcantara® inserts in the grip areas as well as white illuminated AMG door sill panels all help to create some attractive contrasts. Further visual highlights include platinum white contrasting stitching for the upper part of the dashboard, the door beltlines,
the AMG Performance steering wheel and the shift lever gaiter.
Exceptional position: modern assistance systems on board
The SLK 55 AMG sets new standards when it comes to safety: a whole host of the latest assistance systems support the driver and have helped to secure the new AMG Roadster's exceptional position in its segment. Standard equipment includes new, fibre-reinforced roll-over bar, two-stage driver and front passenger airbags, headbags, thorax airbags, seat belt tensioner with degressive belt force limiters, NECK-PRO crash-active head restraints, automatic child seat recognition, three-stage ESP® and also ATTENTION ASSIST drowsiness detection.
Further assistance systems are available on request:
Three generations: the SLK made by AMG
The new SLK 55 AMG is already the third generation of the exclusively dynamic Roadster model made by AMG. It all started in 2001 with the SLK 32 AMG. Its AMG V6 supercharged engine with a displacement of 3.2 litres produced 260 kW (354 hp) and maximum torque 450 Nm – as such, the SLK 32 AMG was the most powerful vehicle among the competition.
At the end of 2004 this was followed by the SLK 55 AMG. With its AMG 5.5‑litre V8 engine, which developed 265 kW(360 hp) and 510 Nm of torque, it also assumed the leading position in its segment. No other vehicle in this class offers a large-displacement eight-cylinder engine – and Mercedes-AMG has remained consistently true to this philosophy with the successor model. The new SLK 55 AMG will celebrate its market launch in January 2012.
The following is a brief overview of pricing (all incl. 19% VAT):
The new Mercedes-Benz C 63 AMG Coupé Black Series
The most powerful C-Class of all time
Spectacular design, technology transfer from the world of motorsport and driving dynamics at the highest level; the new Mercedes-Benz C 63 AMG Coupé Black Series embodies the new AMG brand claim, Driving PerformÂance, like no other AMG model. The new high-performance vehicle is the most powerful C-Class of all time, boasting a maximum output of 380 kW (517 hp) and a maximum torque of 620 newton metres. The AMG 6.3-litre V8 engine impresses with its hefty torque, tremendous pulling power and responsiveness, and ensures high-calibre performance: the C 63 AMG Coupé Black Series accelerates from zero to 100 km/h in 4.2 seconds. Exclusive fun at the wheel comes courtesy of the adjustÂable AMG coil-over sports suspension, the AMG high-performance comÂpound braking system and the functional standard equipment. The AMG Track Package is available as an option to enhance driving dynamics even further. It boasts sports tyres and active rear-axle transmission cooling, plus the AMG Aerodynamics package including flics, a functionally tuned front splitter and an adjustable carbon-fibre rear aerofoil.
Broad, low, brawny and ready to pounce from a standstill – the C 63 AMG Coupé Black Series makes a mighty impression. It’s clear right from the first time you set eyes on it that the C 63 AMG Coupé Black Series is made for ambitious laps on a closed-off race track. In visual terms the new high-performance vehicle is reminiscent of the SLS AMG GT3 customer sports car and symbolises the transfer of technology from the sphere of motorsport, which has been part of the corporate philosophy of Mercedes-AMG GmbH for 44 years now.
With its new C 63 AMG Coupé Black Series, AMG is presenting an exciting sports car for enthusiasts who are passionate about sports cars which are big on horsepower, and this marks the impressive continuation of the Black Seriesstrategy, which began back in 2006. AMG, the performance brand of Mercedes-Benz Cars, is once again demonstrating its expertise when it comes to designing and developing emotionally appealing high-performance cars.
“AMG has its roots in international motorsport. The new C 63 AMG Coupé Black Series is the best proof there is for the permanent transfer of technology from the race track to the road. The numerous successes in the DTM, the customer sports range featuring the SLS AMG GT3 and our commitment to Formula 1, where we have been providing the Official F1ÃSafety Car and the Official F1ÃMedical Car for the past 15 years, continuously spur on our engineers and technicians. The C 63 AMG Coupé Black Series embodies the new AMG brand claim, Driving Performance, like no other AMG model”, comments Ola KÃ¤llenius, the CEO of Mercedes-AMG GmbH.

Arrow-shaped front section with large cooling air openings
It doesn’t matter from which angle you’re looking at it: the new C 63 AMG Coupé Black Series displays its ties with motorsport from every perspective. The arrow-shaped front section with the central Mercedes star in the radiator grille is the visual synonym for its unfettered forwards thrust. The air intakes in the striking front apron ensure reliable air flow through the large cooling modules. Two openings in the aluminium bonnet support the expelling of engine heat, whilst the struts positioned at an angle in the front apron emphasise the vehicle’s width. The black front splitter located at the lower
end helps to balance the vehicle aerodynamically.
The expressive design continues in the side view: the newly developed front axle with a greater track width calls for new wings, which have been widened by 28 millimetres on each side. “6.3” logos give a nod to the sheer power of the large-displacement eight-cylinder high-speed naturally aspirated engine beneath the bonnet. Air outlets intimated behind the wheel cut-outs call to mind powerful racing cars. The onlooker discovers a black strip on the restyled AMG side skirts – a look which continues the idea of the front splitter. On each side the rear wings have also been widened by 42 millimetres, due to the greater track width of the rear axle. Air openings are hinted at in front of the rear wheels, forming a fitting conclusion.
AMG light-alloy wheels featuring light forging technology
255/35 R 19 and 285/30 R 19 – these are the impressive wheel formats for the C 63 AMG Coupé Black Series at its market launch. The wheel/tyre combination is mounted on 9 x 19 (front) and 9.5 x 19 (rear) AMG light-alloy wheels, fills out the wings to stunning effect and plays a significant part in the dynamic appearance of this new AMG sports car.
Painted titanium grey, the high-sheen light-alloy wheels are produced using particularly light forging technology – as is the case on the SLS AMG. These forged wheels weigh a total of eleven kilograms less than comparable wheels with a conventional design. The lower weight results in reduced unsprung masses, which improves both the suspension’s response and the steering precision.
Broad effect of the tail end with a diffuser insert
The tail end of the Black Series coupé is also a feast for the eyes: the new rear apron with its expressive black diffuser insert creates a broad effect. Just like on the SLS AMG GT3, it protrudes beyond the profile of the rear apron. The black grille on the upper end of the diffuser insert is an eye-catching feature, as is the AMG sports exhaust system: both of the chromed twin tailpipes integrated into the rear apron have an angular cross-section. The spoiler lip on the boot lid is painted in the vehicle colour and reduces lift at the rear axle, resulting in more driving stability at high speeds. The AMG logo with its discreet “Black Series” lettering is reserved exclusively for the C 63 AMG Coupé Black Series.
Engine with high-tech components from the gull-wing model
A displacement of 6.3 litres, a maximum output of 380 kW (517 hp) and a torque of 620 newton metres from eight cylinders – one glance at the technical data and it’s clear that the engineering behind the C 63 AMG Coupé Black Series is every bit the equal of its sensational appearance. The high-torque M156 naturally aspirated engine was specially refined for the new two-door model, whose forged pistons, connecting rods and the crankshaft with a lightweight design, for example, all come courtesy of the SLS AMG. These measures are flanked by a new engine control unit. As the car’s performance proves, the uprated V8 engine has an easy time of it in the coupé: the sprint from standing to 100 is over in 4.2 seconds.
Plenty of pulling power, an agile response and hefty torque – the qualities of the large-displacement AMG high-speed naturally aspirated engine arouse unadulterated passion in the driver. The jewel in the crown is the emotive, hallmark AMG eight-cylinder sound from the AMG sports exhaust system.
The optimised engine oil cooling ensures more performance even when the vehicle is put through its paces in harsh race-track conditions. With the aid of components from the SLS AMG, the AMG experts have managed to give the oil cooler a cooling surface which is 50 percent larger. The tried-and-trusted, innovative AMG SPEEDSHIFT MCT 7-speed sports transmission takes care of power transmission. Four transmission modes, the double-declutching function and RACE START promise maximum motoring pleasure and a high degree of variability. In the “Sport plus” and “Manual” transmission modes the gear changes take a mere 100 milliseconds.
AMG coil-over sports suspension with an AMG rear axle differential lock
The AMG sports suspension is a sophisticated new development. It has been designed as a coil-over suspension, as is the norm in motorsport – and it represents a hallmark feature of a Black Series model. It offers numerous setting options, and allows the driver to create their own personal set-up.
The track width of the axles has been widened by 40 (at the front) and 79 millimetres (at the rear) respectively. In conjunction with the modified torsion-bar stabilisers, the C 63 AMG Black Series impresses with its pronounced driving dynamics, high grip and low roll angle. The AMG speed-sensitive sports steering facilitates superb vehicle control: the retuned map control for the power assistance ensures optimum steering precision.
The standard-specification AMG rear axle differential lock is responsible for reliable traction in particular for race-track applications. The 3-stage ESP® offers the ideal solution for all driving situations: via the ESP®button the driver can choose from the “ESP ON”, “Sport Handling Mode” and “ESP OFF” stages. In view of the increased driving dynamics, not only has the anti-lock braking system been completely retuned; the AMG high-performance braking system has also been redeveloped: a larger braking system is now used, with discs featuring compound technology proven in motorsport at the front axle (format: 390 x 36 millimetres) and integral discs at the rear axle (360 x 26 mm). Red-painted six-piston fixed callipers at the front and four-piston fixed callipers at the rear reliably decelerate the perforated, fade-resistant brake discs, which are ventilated all round.
Interior with a functional motor-racing atmosphere
The captivating high-tech components and the spectacular exterior design both find their logical continuation in the interior of the C 63 AMG Coupé Black Series, which is black with red highlight elements, displaying the functional atmosphere of a true racing vehicle, whilst at the same time positively glowing with high quality and lovingly crafted details. Two AMG sports bucket seats facilitate the best levels of lateral support and thus optimum vehicle control on the race track. The black DINAMICA microfibre upholstery on the centre panels of the seats and doors is a new type of synthetic fibre which is characterised by its high lightfastness. The omission of the rear bench seat underlines the vehicle’s sporty character and reduces its weight. As an option the C 63 AMG Coupé Black Series is also available as a four-seater including the AMG sports seats familiar from the C 63 AMG Coupé – and with single seats in the rear.
The AMG performance steering wheel in nappa leather/DINAMICA microfibre with a steering wheel rim featuring flattened top and bottom sections has aluminium shift paddles for manual gear changes. Red seat belts and red contrasting topstitching on the steering wheel, on the seats, door centre panels, armrests on the doors, the centre console and on the shift lever gaiter add some interesting highlights. An exclusive “Black Series”logo adorns the trim on the dashboard, which sports a high-gloss black piano-lacquer look. The dashboard with three autonomous round dials has a three-dimensional TFT colour display. On opening the vehicle door the driver is greeted by AMG lettering. Possible displays for the engine oil temperature, the ESP® mode or the gear selection are integrated into the AMG main menu. The rotary switch for the C, S, S+ and M transmission modes and RACE START is located on the centre console next to the selector lever with a DINAMICA microfibre cover.
The C 63 AMG Coupé Black Series is proof positive that high driving dynamics and excellent active and passive safety need not necessarily be mutually exclusive: five airbags, belt tensioners and belt-force limiters for all seats are part of the standard specification, as are the anti-lock braking system ABS, the 3-stage ESP®, Headlamp Assist, the tyre pressure loss warning system and cruise control with SPEEDTRONIC variable speed limiter.
The standard specification also includes (selection):
AMG Track Package and AMG Aerodynamics package
AMG has two special packages to offer for enhancing driving dynamics even further: the AMG Track Package comprises 255/35 R 19 front and 285/30 R 19 rear sports tyres from Dunlop. They have been exclusively developed for the C 63 AMG Coupé Black Series, and they tangibly and measurably increase grip. Active rear-axle transmission cooling improves performance in punishing race-track conditions. The radiator is located in the rear apron and the airflow passes through it effectively.
What are known as flics are part of the AMG Aerodynamics package. They are made of genuine carbon fibre and located on the front apron. Also included in the package are a functionally tuned front splitter made of genuine carbon fibre and a fixed carbon-fibre rear aerofoil with an adjustable blade. Both components not only increase the lift at the front and rear axle; they also optimise the vehicle’s aerodynamic balance.
Other optional extras include:
Four captivating Black Series models since 2006
Whilst its driving dynamics are totally suited to the race track, the new C 63 AMG Coupé Black Seriesoffers all the properties which characterise a true Mercedes-Benz: suitability for everyday use, durability, safety and quality.
The most powerful C-Class of all time is the fourth Black Series model to be launched since 2006. The first one was the SLK 55 AMG Black Series. The AMG 5.5-litre V8 engine in the decidedly puristic two-seater enticed customers with its maximum output of 294 kW (400 hp) and a torque of 520 newton metres, and between July 2006 and April 2007 120 units were produced. The CLK 63 AMG Black Series followed directly in its footsteps. The two-seater coupé was powered by an AMG 6.3-litre V8 engine with 373 kW (507 hp) and a torque of 630 newton metres. Between April 2007 and March 2008 700 vehicles were made.
The highlight up until now was the SL 65 AMG Black Series, which was unveiled in July 2008: the high-performance coupé still captivates drivers today with its spectacular appearance, unique performance data, systematic lightweight construction and exclusivity of the highest calibre. The AMG 6.0 litre V12 biturbo engine with a maximum output of 493 kW (670 hp) and torque of 1000 newton metres made the SL 65 AMG Black Series the most powerful AMG vehicle ever to enter series production. In total there were 350 units built from September 2008 to August 2009.
The C 63 AMG Coupé Black Series celebrated its world premiere during the Formula 1 race on the Nürburgring. The market launch will follow in January 2012, and its sales price is 115,430 euros (incl. 19% VAT).
