No other car lives up to the standards so famously set by company founder Gottlieb Daimler quite as comprehensively as the top model from Mercedes-Benz. The S 600 with V12 biturbo engine is the top model in the already successfully established S-Class and is available exclusively with long wheelbase and with a luxurious package of equipment and appointments. Its performance data: 390 kW (530 hp) and 830 Nm of torque. The S 600 will have its world premiere at the Detroit Auto Show, with the market launch to follow in March 2014. But the S-Class is about to get even better in other ways, too: the models in the current range will be upgraded with the addition of a head-up display, touchpad and COLLISION PREVENTION ASSIST PLUS.
“The S-Class has always been the embodiment of our claim to deliver the very best in terms of both technology and design” emphasised Ola Källenius, Executive Vice President of Sales and Marketing at Mercedes-Benz Cars. “And our flagship model, the S 600, epitomises the focus of our development work, the ‘Essence of Luxury’, in a way that no other model can. Our customers in North America and Asia in particular will enjoy this new top model with its exciting V12 engine.”
With an output of 390 kW (530 hp), the V12 biturbo engine in the S 600 packs a bigger punch than its predecessor did with 380 kW (517 hp). The displacement of the engine has increased from 5513 to 5980 cc. The maximum torque of 830 Nm is available from 1900 rpm. The S 600 now for the first time features the ECO start/stop function as standard, while it also meets the Euro 6 emissions standard. The combined fuel consumption of the S 600 stands at 11.1 litres/100 km – 21 percent lower than that of its predecessor (14.1 l/100 km).
The most important features of the engine at a glance:
The comprehensive standard specification of the S 600 reinforces its role as a flagship model. The LED Intelligent Light System, the MAGIC BODY CONTROL suspension with ROAD SURFACE SCAN and the Driving Assistance package Plus, for example, all come as standard. The latter comprises Active Lane Keeping Assist, Active Blind Spot Assist, BAS PLUS with Cross-Traffic Assist, DISTRONIC PLUS with STEER CONTROL and Stop&Go Pilot, PRE-SAFE® Brake and PRE-SAFE® PLUS.
Legendary top-of-the-range engine
The figure “600” has long been a legend in the history of the automobile: the model 600 (W 100) launched in 1963 was the first passenger car from Mercedes-Benz to feature a V8 injection engine. This same powerful (184 kW/250 hp) and refined engine was also used from 1967 on in the W 109 model series (in the top-of-the-range 300 SEL 6.3). Further top models to feature a V8 engine included the 450 SEL 6.9 from the model series 116 (210 kW/286 hp) and the 560 SE in the 126 series (220 kW/300 hp in the ECE version). The 600 SE model in the 140 model series of 1991 marked the introduction of the first twelve-cylinder engine as standard in a Mercedes-Benz passenger car. The M 120 delivered 300 kW (408 hp) from a displacement of 6 litres and began a tradition of V12 units as the top-of-the-range engines in the S-Class. Since the 220 series, Mercedes-Benz has also offered especially sporty, AMG-optimised variants with V8 and V12 engines at the top of its S‑Class range, in the form of the S 63 AMG and S 65 AMG.
From March: additional fine touches in the new S-Class
From March, all the functions of the head unit can be controlled by fingertip gesture, as with a smartphone, from the new, optional touchpad. In addition, the touchpad allows letters, numbers and special characters to be entered in handwriting – in any language that is available on the head unit. The touchpad thus offers an additional, full-function input option over and above the existing COMAND Controller and LINGUATRONIC.
A head-up display is also available as an option for the S-Class. As in a jet fighter, it displays important information directly in the driver’s field of view on the front windscreen, so ensuring that the driver’s attention is distracted less from the road ahead. The system provides information on speed, speed limits and navigation instructions, for example.
Replacing COLLISION PREVENTION ASSIST on the S-Class now is COLLISION PREVENTION ASSIST PLUS as standard. In addition to the adaptive Brake Assist system, which helps to protect against collisions at speeds of over 7 km/h, this system now features a further function: if the danger of collision persists and the driver fails to respond, the system is able to carry out autonomous braking at speeds of up to 200 km/h, thereby reducing the severity of collisions with slower or stopping vehicles. The system also brakes in response to stationary vehicles at a speed of up to 50 km/h, and is able to prevent rear-end collisions at up to 40 km/h.
A clear windscreen even at sub-zero temperatures, without all the hassle of scraping, is now possible thanks to electric windscreen heating (optional extra). This is designed to work in conjunction with the air-conditioning blower and ensures clear forward visibility in practically no time at all.
With the Viano Vision Pearl showcar, which will be presented at this year’s International Motor Show in September, 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 design concept is 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 ther exterior design, Mercedes-Benz has for the first time in the van 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 trek king tours – 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.”
Generous spaciousness combined with impressive interior design
The interior of the Viano Vision Pearl is not so much a functional space for passenger transport, but rather a living space.
The name Vision Pearl emphasises both the design concept and the repositioning of the Viano: the Viano of the future is the perfect travelling companion, and in this version it conveys a modern, maritime theme.
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 (the S-Class has 1200 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.
At the 2011 North American International Detroit Auto Show, Mercedes-Benz not only captures visitors’ attention with fascinating automobiles and technical innovations, but enthrals with an art object as well. Interior Design at Mercedes-Benz in Germany has created a sculpture that expresses visually that which inspires designers, and on the other hand gives space to the creative artistic process in the design of the vehicle interior. It makes an aesthetics of sustainability visible and is oriented towards the perfect forms of nature which evolved over periods spanning millions of years.
Mercedes-Benz Aesthetics No. 2 sculpture is this idea made visible. It consciously defies the shackles of the limited context of ergonomics, technical feasibility, formal constraints and, not least, the exterior of the vehicle, in order to impress the observer with its pure sensory-aesthetic appeal. In addition, the sculpture offers a preview of the clear-cut yet emotionally-appealing sculptural form language in the Mercedes-Benz interior design of the future. At the same time it is able to transport the high aesthetic, functional and sensuous aspirations characteristic of a Mercedes-Benz interior, bridging the gap between art and the aesthetics of Mercedes-Benz interior design. It compels the observer to pause for a moment, and challenges, interprets anew that which is already familiar in the vehicle interior, touching both the senses and rational reflection in doing so.
Professor Gorden Wagener, Head of Design: “At Mercedes-Benz, automobile design is artistic creation. Inspiration is the pre-condition for the calm, coherent yet passionately emotional design of our cars. In the interior sculpture Aesthetics No. 2 we have allowed creative fantasy to develop freely without constraints. We have followed Nature’s diversity & perfection; have given her friendliness an expression and a newly-interpreted space. Soft, gentle and infinitely beautiful is her manner of dealing with her resources, creating impressive aesthetics ever anew. We perceive this in every cell structure, every blossom, every living being. However, we do not simply mimic Nature, but learn instead from the intricate, all-encompassing interplay of her elements – this, too, is a hallmark of art.”
Further formal inspiration for the sculpture was suggested by sculpted natural landscapes such as deserts and canyons, but also came from architectural themes and the broad field of aeronautical construction. Thus the seating environment recalls the image of the gigantic wings of a majestic ray fish. The instrument panel produces associations with the wing and engine design of modern jets. The curves of the frame cell structure visually close upon themselves like arches of fluid metal, almost like the bloodstream system of a living organism, while the centre console recalls the skeletal structure of a vertebral column. Life itself, and not lifeless matter, stood model for the Mercedes-Benz interior sculpture. Everything is in flux, interwoven with everything else. In the words of the poet Friedrich von Schlegel (1772-1829): “Art is the nature of Nature.”
On a scale of 1.5 to 1 the sculpture measures 5.6 x 1.83 x 2.6 metres. The finely wrought frame painted in alubeam Liquid Metal is light and strong; the white seating landscapes look like ivory. The Interior Sculpture from Mercedes-Benz sets a multiple chain of associations in movement, symbolising the beauty, style , dynamism and quality of a unique brand history spanning over 125 years. As an automobile work of art Mercedes-Benz Interior Sculpture Aesthetics No. 2 also gives promises of future innovations. In its details it allows vague notions of what the interior of Mercedes-Benz vehicles might be like in the future. An artistic creative-forming process has begun. And reflections about the real future are also allowed.
Thanks to a promotional video, that was more than likely leaked onto the web, the 2012 Mercedes-Benz SLK has been fully unveiled.
The YouTube video has already been pulled, (UPDATE: A new video was found by another one of our readers, thanks Ben. Watch the video below.) but our faithful reader Borwin sent us several screen shots that allow you an in depth look at the all new Mercedes SLK. On the exterior, we can see the SLS AMG styling with integrated trunk-lid spoiler and LED taillights, front quarter vents and adaptive headlights with LED daytime running lights. If adding on the AMG package, you can have a revised front fascia with LED fog lights and AMG wheels with cross-drilled brakes.
Like the SLS, the 2012 SLK has a prominent center console and round air vents. Additnional interior features include sun reflective seasts, draft guard system with is integrated into the roll bars and last but not least, a dash-mounted clock.
As we reported earlier, orders for the new Mercedes-Benz SLK are expected to start with three engine options available to choose from. To start, the SLK 200 BlueEFFICIENCY with 184 hp and 270Nm available (€ 38,650 base price, 6.4 liters / 100), the SLK 250 BlueEFFICIENCY with 204 hp (310Nm – € 44,200, 6.2 litres/100km) and the SLK 350 BlueEFFICIENCY with 306 PS (370 nm – € 52,200, 7.1 liters / 100km) to choose from.
We expect the options list to include the MAGIC SKY CONTRO roof, COMAND Online with internet access, Airscarf and Harman Kardon Audio.
With all the additional leaks of the new SLK, we continue to believe the first introduction will be in January at the North American International Auto Show.
At this year’s Los Angeles Design Challenge, the designers from the Mercedes-Benz Advanced Design Studios in Carlsbad, California, surprised everyone with a revolutionary vision. Taking their inspiration from nature, they designed a vehicle which is fully integrated into the ecosystem, from the moment of its creation right through to the end of its service life. The Mercedes-Benz BIOME grows in a completely organic environment from seeds sown in a nursery. Out on the road the car emits pure oxygen, and at the end of its lifespan it can be simply composted or used as building material.
“As the inventor of the motor car, we wanted to illustrate the vision of the perfect vehicle of the future, which is created and functions in complete symbiosis with nature. The Mercedes-Benz BIOME is a natural technology hybrid, and forms part of our earth’s ecosystem. It grows and thrives like the leaves on a tree” according to Hubert Lee, Head of the Mercedes-Benz Advanced Design Studios in Carlsbad. This year the competition had called for the creation of a vision of a safe and comfortable 2+2 compact car featuring good handling and a first-class design, and weighing only 1,000 lbs (around 454 kg/kerb weight).
Mercedes-Benz symbiosis – a partnership with nature
The Mercedes-Benz BIOME symbiosis vehicle is made from an ultralight material called BioFibre and tips the scales at just 875.5 lbs (around 394 kg). This material is significantly lighter than metal or plastic, yet more robust than steel. BioFibre is grown from proprietary DNA in the Mercedes-Benz nursery, where it collects energy from the sun and stores it in a liquid chemical bond called BioNectar4534. As part of this process, the vehicle is created from two seeds: The interior of the BIOME grows from the DNA in the Mercedes star on the front of the vehicle, while the exterior grows from the star on the rear. To accommodate specific customer requirements, the Mercedes star is genetically engineered in each case, and the vehicle “grows” when the genetic code is combined with the seed capsule. The wheels are grown from four separate seeds.
The Mercedes-Benz BIOME is powered by BioNectar4534, which is stored in the BioFibre material of the chassis, interior, and wheels. In addition, Mercedes-Benz has developed a technology to equip trees with special receptors which can collect the excess solar energy and turn it into BioNectar4534. This creates a direct link with nature’s energy sources and acts as an incentive to cover mobility energy requirements through more trees and at the same time maintain natural resources. Like plants, the Mercedes-Benz symbiosis vehicle also produces oxygen, thereby contributing to improving air quality. At the end of its service life, the Mercedes-Benz BIOME can be fully composted or used as building material. Thanks to the exclusive use of green technologies, the BIOME vehicle thus blends seamlessly into the ecosystem.
Los Angeles Design Challenge
The Los Angeles Design Challenge is part of the Design Los Angeles conference, taking place from 17 to 18 November 2010 as part of the Los Angeles Auto Show. The winner of the competition will be announced on 18 November 2010.
The next-generation Mercedes-Benz CLS63 AMG four-door coupe will make its world debut at the 2010 Los Angeles Auto Show, open to the public November 19-28 at the Los Angeles Convention Center. Other new Mercedes-Benz models at the L.A. Auto Show will include the redesigned CL coupe and R-Class crossover lines as well as the all-new E-Class Cabriolet. In addition, an update about the launch of the fuel cell-powered Mercedes-Benz F-CELL car will take place during a press conference at the Mercedes-Benz exhibit.
High-Performance CLS63 AMG Four-Door Coupe
Center stage at the L.A. Show, the all-new 2012 CLS63 AMG will be powered by a new 5.5-liter biturbo V8 that produces more power and better fuel economy. With twin turbochargers, direct fuel injection and multi-spark ignition, the new AMG engine will produce 518 horsepower and 516 lb.-ft. of torque. The new CLS63 AMG will also come with AMG’s award-winning MCT (for multi-clutch technology) transmission and innovative systems designed to reduce fuel consumption. For even more performance, the CLS63 AMG will be available with an optional Performance Package that includes increased power – 550 hp and 590 lb.-ft. of torque.
With fresh body lines that accentuate the distinctive shape of the swoopy four-door coupe, the new-generation CLS-Class represents the first major redesign of a car that established an entirely new market segment – the four-door coupe. Defining yet another market segment in an ever-expanding and highly competitive auto industry, the CLS was the first four-door vehicle to combine the emotional appeal and dynamic design of a coupe with the comfort and functionality of a four-door sedan.
The Fuel-Cell-Powered F-CELL
In addition, an update about the U.S. rollout of the fuel-cell-powered Mercedes-Benz F-CELL car will take place at the Mercedes-Benz exhibit during news media activities prior to the public opening of the show. Essentially an electric car that makes its own power on board, the Mercedes-Benz F-CELL boasts 54 miles per gallon (EPA combined city-highway equivalent fuel mileage) and a range of about 230 miles. Running on compressed hydrogen, and with water as the F-CELL’s only exhaust emission, the hydrogen and air react without combustion in the fuel cell, producing current to run the 136-horsepower electric motor. The F-CELL is also equipped with a 35-kilowatt lithium-ion battery that stores recovered braking energy, helps provide instant acceleration and ensures fast starting in very cold weather.
The hydrogen gas is stored in 10,150-psi tanks that can be refueled in only three minutes. Beginning in Southern California, the new F-CELL car is being offered through a lease program in markets with growing networks of hydrogen refueling stations.
Other New Mercedes-Benz Models
The 2011 Mercedes-Benz CL – the company’s premium two-door coupe – is also on display at the L.A. Auto Show. Restyled for 2011, its refinements include an aggressive front hood with two wide recesses and sleeker front fenders incorporating bi-xenon headlights, LED turn signals and daytime running lights. New rear styling features dual exhaust pipes that exit through a new bumper, back-up lights integrated in the trunk lid and LED taillights.
The 2011 CL coupe line is comprised of four distinctive models. The all-wheel-drive CL550 4MATIC is powered by a 4.6-liter version of the new biturbo V8 that produces 429 hp and 516 lb.-ft. of torque. Like the CLS63 AMG, the high-performance CL63 AMG model now comes with AMG’s new 5.5-liter biturbo V8 (536 hp, 590 lb.-ft.) and AMG’s MCT transmission. The V12- powered CL600 (510 hp, 612 lb.-ft.) and the CL65 AMG (621 hp, 738 lb.-ft.) round out the 2011 CL coupe line.
The latest addition to the successful Mercedes-Benz E-Class line, the two-door, four-seat Cabriolet will share the spotlight with the CLS63 AMG and the F-CELL car. The Cabriolet features a classic fabric soft top that can be opened or closed in 20 seconds, even at speeds up to 25 mph. The two-door Mercedes-Benz E-Class Cabriolet family is available with the choice of a V6 or V8 engine. The E350 uses the latest four-valve-per-cylinder V6 engine that produces 268 horsepower and 258 lb.-ft. of torque, while the E550 model is powered by a 32-valve 5.5- liter V8 delivering 382 hp and 391 lb.-ft. of torque.
The 2011 R-Class crossover features a redesigned front hood and bolder grille as well as new fenders and headlights, sleeker side mirrors and LED taillights. A new rear bumper includes an integrated reflector, dual exhaust outlets and a black air diffuser. The 2011 interior reveals a 3D instrument cluster and “saddle” head restraints for the 2nd and 3rd row seats as well as new wood trim and seat stitching throughout.
Mercedes-Benz is not only treating visitors to the North American International Autoshow 2010 in Detroit to the world premiere of the new E-Class Cabriolet and innovative technology, but also placing a beautifully executed automobile sculpture at centre stage. It represents a vehicle body taking soft, flowing form from a level surface – as if an automobile of liquid silver was being created, or a shimmering cloth was gently draped over a newly conceived design. As if by a natural process, clearly contoured surfaces are ordered and delineated by sharply drawn, curved lines. They lend the sculpture an organic appearance, giving it a future and origin.
The sculpture is an exclusive, sensuous creation and extraordinarily eye-catching. But it also transports car design into a new, artistic reality. “To us, automobile design means artistic, aesthetically and sensuously oriented creation”, says Head of Design Prof. Gorden Wagener. “Mercedes-Benz designers translate their artistic inspiration into the modern idiom of Mercedes-Benz automobile design, which combines dramatic details with harmony, style and passion. Mercedes-Benz design is clear, calm and consistent, but yet emotional and highly sensuous. Mercedes-Benz is the brand best able to present automobile design as an art form in an authentic way.”
As an extraordinary jewel of automotive artistry, the sculpture uses its flowing, cloth-like connection to its surroundings and the resulting pattern of folds to symbolise the positively and negatively curved surfaces of the modern Mercedes-Benz design strategy. This is characterised by dramatic, full surfaces whose proportions are attractively defined by fine, softly emerging but sharply contoured lines.
Viewing the sculpture can conjure up many associations. Perhaps a sand dune or a snowdrift, a viscous substance such as hot lava or mercury from which an automobile is being created. The sculpture imitates the formative power of nature: flowing elements change their shape as the form of a new automobile emerges in line with the dynamic laws of gravity and aerodynamics, making this form vaguely visible and solidifying into a work of art with the appearance of a casting possessing contours and clear definitions. It shows shapes and lines that appear natural gradually taking the form of a vehicle body, a sensuous basic structure on which curving, sinewy lines create emotional contours. An aesthetic transformation, “shaped by nature” and the artistic imagination of the designer.
Inspired by and taking its origin from the forces of nature, this artistically executed sculpture also symbolises the key basic values of the Mercedes-Benz brand – intelligent technology and quality, sensuous beauty, style, dynamism and innovative strength for well over a century. Coupled with respect for man and nature. Mercedes-Benz is one of the few automobile companies able to communicate this credibly as a work of art.
This is also reflected in the shining Alubeam silver paint finish, which interacts with the contours of the sculpture to create multi-facetted areas of light and shade. At the same time this Mercedes colour is a reference to the glorious motor racing history of the Mercedes-Benz brand, but also suggests visions of the day after tomorrow and promises the innovations of the future.
This high-quality sculptural depiction was essentially created as an attempt by Mercedes-Benz Design to show the cultural feeling and creativeness of its designers in the five international design studios in Germany, Italy, the USA, Japan and China, to further their artistic ideals and develop a design for Mercedes-Benz. “Many of our designers come from artistic families, carry artistic ambitions in their genes, so to speak, and found their way into automobile design via their artistic talent,” is how Prof. Gorden Wagener explains the potential.
With this sculpture, Mercedes-Benz provides an insight into the thinking and perceptions of its team of designers and model-makers. While a design idea initially takes shape on paper, it is subsequently modelled in clay. This is sculptural work in its purest form, and eminently suitable for finding new shapes and creating sensuousness. The automobile as an art form, with heavy concentration on attention to detail that also includes the interior design and choice of materials.
Designing and modelling at Mercedes-Benz Design has a great deal to do with creativity and the work of artists – though art for art’s sake is certainly not the intention behind this sculpture! The form of an automobile that suggests itself here in such an artistically sophisticated and encoded way is only vaguely perceptible. Nonetheless the basic proportions challenge the onlooker to interpret the shape of the future, real product that may be nearing the end of its flowing design process. Amazement and speculation in equal measure.
Automotive fascination and high-tech at the highest level: the new Mercedes-Benz SLS AMG, which is due to be launched in spring 2010. This Gullwing model captivates with a purist design, intelligent lightweight construction and superior handling dynamics, and is bound to cause a sensation in the super sports car segment. The new SLS AMG is nothing short of a masterpiece by Mercedes-AMG GmbH. As the first independently developed vehicle, the super sports car is the highlight in the company’s more than 40-year history. It not only takes AMG, the performance brand within Mercedes-Benz Cars, into a new era, but also demonstrates development expertise of the very highest order.
The new super sports car from Mercedes-Benz and AMG makes for an alluring proposition with its unrivalled technology package: aluminium spaceframe body with gullwing doors, AMG 6.3-litre V8 front-mid-engine developing 420 kW (571 hp) peak output, 650 Nm of torque and dry sump lubrication, seven-speed double-declutch transmission in a transaxle configuration, sports suspension with aluminium double wishbones and a kerb weight of 1620 kilograms based on the DIN standard – this superlative combination guarantees driving dynamics of the highest order. The front/rear weight distribution of 47 to 53 percent and the vehicle’s low centre of gravity are testimony to the uncompromising sports car concept. The ‘Gullwing’ accelerates from 0 to 100 km/h in 3.8 seconds, before going on to a top speed of 317 km/h (electronically limited). The fuel consumption of 13.2 litres per 100 kilometres (combined) puts it at the front of the competitive lineup.
Design: purist, distinctive and passionate
The purist design of the new Mercedes-Benz SLS AMG captivates by virtue of its passionate sportiness, and its reinterpretation of the Mercedes-Benz 300 SL’s breathtaking design lines. The stylistic highlights are the striking gullwing doors, which lend an incomparable charisma to the SLS AMG. The long bonnet, the low greenhouse positioned well to the rear and the short rear end with its extendable rear aerofoil stand for dynamism, as do the long wheelbase, the wide track and large 19 and 20-inch wheels. It is not only the gullwing doors that are reminiscent of the Mercedes-Benz 300 SL, as the wide radiator grille with its large Mercedes star, the wing-shaped cross fin and the fins on the bonnet and flanks also hark back to the legendary sports car of the 1950s.
Eyecatching features of the side view include the accented wheel arches and the pronounced shoulder line, which extends from the front to the rear end like a taut muscle. Dynamism and power are also communicated by the rear view of the SLS AMG: the gentle slope of the boot lid with the automatically extending aerofoil accentuates the impression of width, as do the flat LED tail lights.
Interior with a touch of aircraft engineering
Mercedes-Benz designers took their inspiration from the aviation world when designing the interior. The stylistic centrepiece is the dashboard, which ensures a visual impression of breadth with its muscular, wing-like profile. The four air vents with adjustable cruciform nozzles are prominently integrated into the dashboard – their shape is reminiscent of a jet engine. The design theme of an aircraft cockpit is also reflected in the long centre console of matt-finished, solid metal. Features integrated into this include the AMG DRIVE UNIT, which enables the driver of the SLS AMG to choose a personal vehicle setup. The AMG SPEEDSHIFT DCT 7-speed sports transmission is operated by the E-SELECT lever, which resembles the thrust control of a jet aircraft. Despite the low seating position typical of a sports car, the wide-opening gullwing doors allow easy access and egress. They require less opening space than conventional coupé doors, and can be fully opened in a standard-size garage.Aluminium spaceframe for lightweight design and high strength
The SLS also breaks the mould when it comes to the body concept: for the first time, Mercedes-Benz and AMG are presenting a car with an aluminium chassis and body. Compared with the traditional steel design, this results in a significant weight saving, as is clearly illustrated by the DIN kerb weight of 1620 kilograms.
The newly developed bodyshell consists of an aluminium spaceframe. This exclusive design combines intelligent lightweight design with outstanding strength – thus delivering superlative driving dynamics. Lightweight aluminium sections connect the frame nodes to form a sturdy structure. These aluminium sections ensure high strength, and ensure the necessary, direct transfer of drive, braking and suspension forces. The structure prevents unwanted flexibility; the vehicle responds rigidly, directly and with practically no torsion.
45 percent of the intelligent, weight-optimised aluminium spaceframe is made from aluminium sections, 31 percent from sheet aluminium, 20 percent from cast aluminium and 4 percent from steel. Maximum occupant safety requires the use of ultra-high-strength, heat-formed steel in the A-pillars. The bodyshell weighs 241 kilograms – an absolute benchmark in the super sports car segment in relation to the peak output of 420 kW (571 hp). With a DIN kerb weight of 1620 kilograms, the power-to-weight ratio is an extremely favourable 2.84 kilograms per hp.
Low centre of gravity and transverse reinforcing struts for superb dynamism
The entire vehicle concept has been designed to achieve a centre of gravity that is as low as possible. This applies both to the low connection of the powertrain and axles as well as to the arrangement of the rigidity-related bodyshell structure. Examples include the rigid flexural and torque connections between the front and rear sections and the safety passenger cell, which have been realised using force paths that are consistently 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 three-point seat belts with belt tensioners and belt force limiters, and up to eight airbags: adaptive front airbags for the driver and passenger, a kneebag for each, two seat-integrated sidebags and two windowbags deploying from the waistlines of the gullwing doors.
Fine-tuned AMG 6.3-litre V8 engine developing 420 kW (571 hp)
A powerful eight-cylinder Mercedes-AMG engine forms the heart of the new SLS. The fine-tuned 6.3-litre V8 engine develops 420 kW (571 hp) at 6800 rpm, making the SLS AMG one of the most powerful sports cars in its segment. A power-to-weight ratio of 2.84 kg/hp comes courtesy of the low vehicle weight. The naturally aspirated engine delivers its maximum torque of 650 Nm at 4750 rpm. The SLS accelerates from 0 to 100 km/h in 3.8 seconds, and has an electronically limited top speed of 317 km/h. Bearing the internal designation M 159, the high-revving V8 engine with its displacement of 6208 cubic centimetres has been thoroughly reengineered compared to the basic M 156 engine, and boasts all the hallmarks of powerful racing engines.
The principal measures in increasing output include the all-new intake system, the reworked valve train and camshafts, the use of flow-optimised tubular steel headers and the dethrottling of the exhaust system. This results in much better cylinder charging, which feeds through into an increase in output by almost nine percent — 34 kW (46 hp). The eight-cylinder engine responds swiftly to movements of the accelerator pedal, demonstrating much more pronounced high-revving flexibility across the entire rev range. The switch to dry sump lubrication also translates into a much lower installed engine position. And lowering the vehicle’s centre of gravity has also paved the way for high lateral acceleration and exhilarating driving dynamics.
Perfect synthesis of lightweight design and strength
The use of high-strength components compensates for the increased engine loads associated with the higher output. Forged pistons, a reinforced crankshaft bearing, optimised crankcase structure, along with improved lubrication thanks to a demand-controlled, high-performance oil pump ensure optimum durability. Despite these higher loads, the engine weight for the M 159 has been further reduced. The forged pistons as oscillating masses play a particularly valuable role in this respect, resulting in a kerb weight of 205 kilograms and, in turn, a power-to-weight ratio of 0.36 kg/hp – an unrivalled figure compared with the competition. Sophisticated catalytic converter technology enables current and future exhaust emission standards such as EU 5, LEV 2 and ULEV to be met.
Enables demanding fuel consumption targets to be met
Despite its uncompromisingly sporty character, very ambitious fuel consumption targets have been met. The SLS AMG consumes 13.2 litres per 100 kilometres (combined, provisional figure), earning it a place at the top of the competitive ranking. 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 and braking, 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.
Double-declutch 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-declutch 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 virtually 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.
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 Gullwing model comes with 3-stage ESP® as standard, and the driver can choose 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.
Acceleration skid is controlled 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 composite high-performance braking system available as an option
The AMG high-performance braking system with composite brake discs at the front ensures extremely short stopping distances even under high loads. 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: weight-optimised AMG light-alloy wheels – 9.5 x 19 inch (front) and 11.0 x 20 inch (rear) – 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; individual tyres are shown on the display.
The SLS AMG as a masterpiece in AMG’s more than 40-year history
The new SLS AMG is a true masterpiece on the part of Mercedes-AMG GmbH. As the first independently developed car, the super sports car is the highlight of the company’s more than 40-year history. With this car AMG, the performance brand within Mercedes-Benz Cars, is not only entering a new era, but also demonstrating development expertise of the highest order.
AMGwas established in 1967 by Hans Werner Aufrecht and Erhard Melcher, and is considered a pioneer in the field of vehicle tuning for motorsports. Following the cooperation agreement concluded in 1990 with Daimler-Benz AG, the company was gradually incorporated into what at the time was DaimlerChrysler AG in 1999. On 1 January 2005, DaimlerChrysler AG acquired 100 percent of the shares. Today Mercedes-AMG GmbH is a vehicle manufacturer in its own right, and AMG is the performance brand within Mercedes-Benz Cars. This subsidiary of Daimler AG specialises in unique, high-performance vehicles; its sporty saloons, SUVs, coupés, cabriolets, roadsters and specially built one-off models constitute a product portfolio which meets its customers’ every wish. The product range encompasses a total of 16 AMG high-performance models with outputs ranging from 265 kW (360 hp) to 450 kW (612 hp).
Mercedes-AMG has overall responsibility for developing the design, aerodynamics, interior as well as the powertrain, engine, suspension, brakes and electronics – right up to granting final approval for production of the complete AMG vehicle. The company is also in charge of all marketing and sales-related activities for its products.
The highly appealing and emotionally charged Cabriolet is the latest addition to the successful Mercedes-Benz E-Class line-up. The open-top two-door model, which goes on sale on 11 January 2010, features a classic fabric soft top, making for a stylistically pure cabriolet feeling. Viewed from the side, the new model is an intriguing proposition – with its clear proportions and a flawless cabriolet silhouette.
In keeping with the motto “four seasons, four passengers”, all-year-round suitability was right at the top of the developers’ list of priorities. With the new E‑Class Cabriolet, the cabriolet season lasts the whole year because, while many cabriolets tend to disappear from the roads of Western Europe in the autumn, the Mercedes-Benz E-Class Cabriolet (length/width/height: 4698/1786/1402 mm) provides driving pleasure and comfort whether the roof is open or closed.
New features include:
The soft top can be opened and closed fully automatically within 20 seconds – even when driving at speeds of up to 40 km/h. The cabriolet roof is stowed in a special compartment behind the rear panel. A retractable cover separates the soft top compartment from the boot area; it must be closed in order to close the soft top. If the roof is to remain closed, the cover can be slid rearwards, in which case the boot capacity is increased by 90 litres to 390 litres. A through-loading feature is included as standard for the new Cabriolet, as is EASY-ENTRY – a manually operated entry and exit aid for the rear passengers.
The powerplants for the new E-Class Cabriolet are equally innovative: the new direct-injection diesel and petrol models combine efficiency with effortlessly superior power delivery. The exemplary, low fuel consumption has not only been achieved because of the new engines, but also with a number of practical measures. These include on-demand activation of the steering and fuel pumps, the use of tyres with low rolling resistance and an alternator control system which takes account of the current driving situation and the vehicle’s electrical power requirements, plus the crucial factor of outstanding aerodynamics. The Cabriolet’s cd figure of 0.28 is the best in its class, marking a continuation of the E-Class success story in the field of aerodynamics.
An overview of the engines:
In 1989, Mercedes-Benz introduced a world premiere in the shape of a draught-stop for the SL model series, followed in 2004 by the AIRSCARF® neck-level heating system to further enhance comfort in open-top models. Now comes another world-first: the AIRCAP® automatic draught-stop, which can be activated at the push of a button, greatly reduces turbulence in the interior of the new Mercedes E-Class Cabriolet, creating a sea of warm air. It is also much easier to implement and use than conventional draught-stops: there is no tricky installation, the two individual rear seats remain free and the Cabriolet’s flowing side lines remain uninterrupted. AIRCAP® is therefore a classic Mercedes innovation: functional, comfort-enhancing, elegant and safe.
AIRCAP® consists of two components: a wind deflector that can be extended by around six centimetres with a net in the windscreen frame and a draught-stop between the rear seats.
The functions of the two components:
As well as enhancing occupant comfort and wellbeing, the reduction in draught when AIRCAP® is activated (it can be activated at speeds of up to 160 km/h and remains in use right up to the car’s top speed) reduces the interior noise level – so passengers in all seats find it far easier to communicate.
The Cabriolet Comfort package includes AIRCAP® with AIRSCARF®. This patented system functions like an invisible scarf, which warms the occupants’ head and neck areas. AIRSCARF® is integrated into the backrests of the front seats and provides warm air through outlets in the head restraints.
The Mercedes engineers have modified this unique innovation specifically for the E-Class Cabriolet: in this model, an adjustment wheel pivots the outlet nozzle upwards and downwards by a total of 36 degrees over and above the head restraint height adjustment, meaning that the driver and front passenger can enjoy the unique neck-level heating regardless of how short or tall they are.
Quiet, warm and windproof: acoustic soft top fitted as standard
Thanks to its acoustic soft top, fitted as standard, even the closed E-Class Cabriolet has one of the quietest interiors in the segment for four-seater premium
cabriolets with a fabric roof. The soft top’s exceptionally high-quality insulation brings about a clearly noticeable reduction in the interior noise level compared to conventional fabric soft tops. Exterior noise caused by other vehicles and wind noise are therefore absorbed more effectively. On the road, the difference is audible from speeds of just 80 km/h, for example when driving through a tunnel or overtaking a convoy of trucks. At higher speeds, the benefits of the acoustic soft top are even more tangible. For instance, it is possible to have a perfectly normal phone conversation in hands-free mode even when travelling at a speed of over 200 km/h.
The soft top is of course waterproof and windproof. Plus it can be put through an automatic car wash without any hesitation. With a total thickness of 23.5 mm, the fabric soft top offers excellent thermal insulation, meaning that the E-Class Cabriolet is also ideal for use in winter.
Safety: robust structure, anticipatory protection and windowbags
The new Cabriolet offers the wealth of safety innovations one would expect from a Mercedes model. Highlights of the open-top two-door model include roll-over protection, the A-pillars reinforced by two additional tubes and the plug-in B‑pillars. This new model is also the first Mercedes cabriolet to feature headbags.
The roll-over protection consists of two robust bars, each with a diameter of 35 mm, which are housed in the rear head restraints in modules behind the rear seat backrests. A tilting cone sensor detects imminent danger to the occupants based on extreme skidding movements or acceleration caused by impact. If this sensor then sends a corresponding signal, pre-tensioned pressure springs are activated by pyrotechnic means, i.e. extremely quickly.
Consequently, both roll-over bars in the rear head restraints are extended. They reach their highest point and are locked automatically within a fraction of a second. In combination with the robust A-pillars, each of which is reinforced with two high-strength steel tubes, the steel bars provide highly effective roll-over protection.
The plug-in B-pillars are extremely robustly connected as they engage in the side skirts, thus offering highly effective protection in the event of a crash. A shoe made from ultra-high-strength steel braces the inside of the B-pillar against the rear seat crossmember.
With seven airbags fitted as standard, belt tensioners and belt force limiters for all seats, not to mention crash-responsive head restraints for the driver and front passenger, the new E-Class Cabriolet offers the most extensive safety equipment package in this vehicle category. The airbags, which can deploy in milliseconds in the event of an accident, include front airbags and sidebags for the driver and front passenger, a kneebag on the driver’s side, and headbags. The latter, which appear in a Mercedes cabriolet for the first time, are housed in the door panelling in the beltline area. Covering a wide area – around 0.7 x 0.5 metres with a volume of 17 litres when deployed – the airbags provide extremely effective protection for occupants large and small in the event of a crash. The three-part side protection system – comprising headbag and thoraxbag – optimises the level of protection afforded to individual parts of the body. Rear sidebags are available as an option.
Further exemplary safety equipment available for the E-Class Cabriolet includes ATTENTION ASSIST drowsiness detection, PRE-SAFE® anticipatory occupant protection, the sophisticated Intelligent Light System, the Active Bonnet and DISTRONIC PLUS proximity control.
Mercedes-Benz is celebrating the world premiere of the new E-Class Cabriolet at the North American International Autoshow 2010. It not only completes the successful E-Class family, but also features a world first: the AIRCAP® draught-stop, an easily operated system that considerably reduces wind turbulence in the open interior of this all-year convertible. The stars on show in Detroit also include the new Mercedes-Benz SLS AMG, a Gullwing model that combines automotive passion and high-tech at the highest level. Mercedes-Benz is also presenting a surprise in the shape of a beautifully executed automobile sculpture, a work that alluringly communicates car design as a new art form.
Mercedes-Benz is adding a particularly attractive and emotionally appealing member to the successful E-Class family with the new Cabriolet. Thanks to its classic fabric soft-top, this four-seater convertible provides open-air driving pleasure in its purest form.
In line with the motto “Four seasons, four people”, all-year suitability was at the top of the specification list for the developers. Features ensuring year-round open-top driving enjoyment include the automatic AIRCAP® air deflector and draught-stop system. This can be deployed at the touch of a button, and considerably reduces wind turbulence in the interior of the new Mercedes E-Class‑Cabriolet, so that a “warm air bath” is created even when the roof is open. It also eliminates the installation procedure for conventional angled draught-stops, the individual rear seats remain accessible and the side contours of the Cabriolet are not disrupted.
Comfortable travel with the roof closed is ensured by the standard acoustic soft-top, which has a particularly high level of sound insulation. With the roof closed, the E-Class Cabriolet has one of the quietest interiors in the four-seater premium convertible segment with a fabric roof. The roof can be fully automatically opened and closed within 20 seconds – and even on the move up to a speed of 40 km/h.
Standard equipment also includes a further development of the AIRSCARF® neck-level heating system integrated into the front seat backrests, which blows warm air from adjustable vents in the head restraints to warm the neck and shoulder area of the seat occupant like an invisible scarf.
The E-Class is the heart of the Mercedes-Benz brand. With the new Cabriolet, the E-Class family now has four attractive models. Trailblazing innovations characterise all the variants in the E-Class model series. They include direct-injection diesel and petrol models that combine high efficiency with superior power delivery. Exemplary safety features include the drowsiness detection system “ATTENTION ASSIST”, the preventive occupant protection system PRE-SAFE®, the advanced technology of the “Intelligent Light System”, the active bonnet and the proximity control system “DISTRONIC PLUS”.
Over and above the innovations shared by all the models in this family, the individual variants have new features that enhance comfort, safety and attractiveness on a model-specific basis. The E-Class is the clear leader in its market segment: In Germany the market share of the E-Class Limousine in its comparative segment is approx. 60 percent and in Western Europe (excluding Germany) over 40 percent.
Mercedes-Benz SLS AMG
The new Mercedes-Benz SLS AMG, due to be launched in spring 2010 offers automotive passion and high-tech at the highest level. This Gullwing model dazzles with its purist design, intelligent lightweight construction and superior handling dynamics. The new SLS AMG is nothing short of a masterpiece by Mercedes-AMG GmbH. As its first completely independently developed vehicle, the super sports car is the highlight in the company’s‑more than 40-year history.
The new Mercedes-Benz SLS AMG is an alluring proposition with its unrivalled technology package: an aluminium spaceframe body with gullwing doors, AMG 6.3-litre V8 front-mid-engine developing 420 kW (571 hp) peak output, 650 Nm of torque and dry sump lubrication, seven-speed double-declutch transmission in a transaxle configuration, sports suspension with aluminium double wishbones – this superlative combination guarantees driving dynamics of the highest order. This ‘Gullwing’ accelerates from 0 to 100 km/h in 3.8 seconds, and has a top speed of 317 km/h (electronically limited).
The purist design of the new Mercedes-Benz SLS AMG impresses with its passionate sportiness, and reinterprets the breathtaking lines of the Mercedes-Benz 300 SL. As the stylistic highlight, the striking gullwing doors give the SLS AMG an incomparable charisma.
Art and automobile design
Mercedes-Benz is not only treating visitors to the North American International Autoshow 2010 in Detroit to the E-Class Cabriolet and the SLS AMG, but also to a beautifully executed automobile sculpture. It represents a vehicle body taking soft, flowing form from a level surface, suggesting the shape of a car in a sophisticated and encoded manner – as an exclusive, sensuous creation. The sculpture is therefore a work that alluringly communicates car design as a new art form. It shows that designing and modelling at Mercedes-Benz Design has a great deal to do with creativity and the work of artists. Naturally the sculpture also challenges the onlooker to speculate which future, real product may be nearing the end of its flowing design process here.
In the search for the optimum hybrid system for the premium motor car, the engineers were already sure of one thing right from the concept phase: a Mercedes-Benz SUV with a hybrid drive would have to share the same typical brand attributes as any other Mercedes vehicle. Essential elements such as the greatest possible active and passive safety, optimum ride comfort and ease of operation, uncompromising reliability over a long period and high-quality workmanship with select materials would have to be on a par with a comparable, conventionally powered standard-production vehicle. And all combined with the greatest possible efficiency.
At the same time, the drive system should be testimony to the company’s innovative strength and cutting-edge technology. These objectives demanded a complete development cycle – the kind of process any new model family developed from scratch would undergo. Until the Mercedes-Benz ML 450 HYBRID reached series-production maturity, the engineers and technicians clocked up a total of four million kilometres, taking in some of the world’s most extreme climatic conditions to prove the system’s reliability, be it in the sub-zero Arctic circle, the searing heat of arid desert regions or in the sweltering, humid temperatures of the tropics. The work was supplemented by an extensive test-rig programme and detailed simulations as part of the “Digital Prototype”. An important aim during development was to optimally match the various subsystems within the powertrain. System matching enables the various drive modes to be easily used while the customer is driving.
The two-mode hybrid technology in the ML 450 HYBRID, whose drive architecture supports purely electric operation and purely combustion engine operation or any combination of the two, takes its lead from the fundamental work undertaken by the “Global Hybrid Cooperation”. This group brought together research and development work undertaken by the companies Daimler AG, BMW Group, General Motors and Chrysler.
Superior technology: two-mode hybrid for the most efficient drive system
Thanks to two-mode hybrid technology the ML 450 HYBRID boasts tangible benefits: its performance figures are on a par with a conventional eight-cylinder SUV with permanent all-wheel drive while fuel consumption and emissions have been reduced by up to 60%. The vehicle designed specifically for the US market delivers ‘city’ fuel consumption of 21 mpg and ‘highway’ consumption of 24 mpg, making it the most efficient vehicle in its segment. With its SULEV (Super Ultra Low Emission Vehicle) classification, the SUV meets the most stringent emissions standard for vehicles with a combustion engine currently applicable in the US. At the same time, the ML 450 HYBRID with a system output of 250 kW (340 hp) and a combined torque of 517 newton metres guarantees a superlative driving experience combined with an enhanced level of ride comfort. The driver can concentrate fully on the traffic and enjoy the ML 450 HYBRID driving experience without having to select additional functions as the drive management system is fully automatic. The functionality of the 4MATIC permanent all-wheel drive system is also fully retained.
At the heart of the two-mode hybrid drive is the transmission unit with two compact electric motors, three planetary gear sets and four clutches. This configuration enables the power to be split into an electrical and a mechanical path. Conventional one-mode hybrid systems tend not to have mechanical ratios. As such, this kind of system transfers the bulk of the power via the electrical path with high electrical output and hence lower efficiency. It works efficiently principally at lower loads and speeds. If power also needs to be transferred at higher loads and speeds, an accordingly larger electric motor would be required. Having to power and find space for this engine would only be possible at the expense of efficiency. In response to increasing engine loads and higher speeds, two-mode technology, by contrast, variably shifts the power transfer from the electrical path to the mechanical drive path. As a result, the system is much more efficient in all situations, both in inner-city stop-and-go traffic as well as on fast motorway journeys, while also enabling smaller electric motors to be used. The efficiency boost – both in urban traffic as well as on motorway journeys – is therefore where “two-mode” technology gets its name from.
The four clutches are used to distribute the driving force generated by the electric motor and combustion engine via four fixed ratios and two electric variable ratios to all four wheels on the 4MATIC permanent all-wheel-drive system, depending on the driving situation. Various strategies ensure the best possible fuel consumption and performance, depending on the traffic situation or the driver’s requirements:
The two compact electric motors boast a high power density and are fully integrated into the transmission housing. The limited installation space means the two electric motors have to be configured differently. The first electric motor – positioned nearer to the combustion engine – develops 62 kW (85 hp) and 235 newton metres of torque and has been designed with power output and minimal losses firmly in mind. The electric motor placed at the end of the transmission develops 60 kW (82 hp) and 260 newton metres and is thus the ideal solution for moving off solely under electric power and providing the booster function.
Compact 288-volt battery with high power density
A battery management function monitors and controls the various charge flows during electric motoring, boost or recuperation to ensure a stable charge state. The entire high-voltage onboard network complies with the most stringent safety standards.
Sophisticated management system computes the most fuel-efficient operating mode in real time
Operation of the two external rotor magneto motors and the management of the entire high-voltage onboard network requires complex control electronics housed in the engine compartment of the ML 450 HYBRID. Waste heat from the electronics is dissipated via a separate cooling circuit to increase efficiency. An integrated Auxiliary Power Module enables power to be exchanged between the 288-volt battery and the 12-volt onboard network.
A powerful computer controls the hybrid system with up to 50 million computing operations a second. The electronic control unit calculates the most efficient operating mode 160 times a second, thus ensuring the lowest possible fuel consumption. The management system also supports new functions and comfort/convenience features:
* exclusive features of the ML 450 HYBRID
Consumption-optimised Atkinson V6 engine
The modified 3.5-litre V6 petrol engine has been optimised in accordance with the Atkinson process, delivering substantially better fuel consumption and emissions figures with an output of 205 kW (279 hp) and a maximum torque of 350 newton metres. The development engineers utilised some of the benefits of the Atkinson principle whereby the expansion phase is longer than the compression phase. The intake valve is kept open slightly longer between the intake and compression phases, which improves the engine’s thermal efficiency while reducing the specific fuel consumption and untreated emissions. This process is not used with conventionally powered vehicles because Atkinson engines – apart from the lower fuel consumption and emissions – tend to deliver lower torque at lower revs and thus inferior response particularly at low engine speeds. On the ML 450 HYBRID this drawback is more than offset through the use of the electric motors when moving off normally, accelerating or using the booster function. The M-Class thus offers superb responsiveness and agility.
Compared with the conventional 3.5-litre V6 petrol engine, the Atkinson version features a modified cylinder head, pistons and camshaft. The camshaft timing has also been modified. The newly developed regulated oil pump adjusts the flow rate to the engine’s actual requirements, thus minimising the necessary delivery rate and helping reduce fuel consumption and emissions. Since the alternator and starter functions are integrated in the two electric motors, these two components, which are now surplus to requirements, no longer need to be connected up to the belt drive on the combustion engine. The air conditioning compressor and the steering servo pump are another two components that do not need to be powered via the belt drive. These are driven electrically on the ML 450 HYBRID and can be run independently of the combustion engine.
Operating strategies of the two-mode hybrid drive
The ML 450 HYBRID offers the full range of extra functions offered by a hybrid drive. These include variable hybrid mode for city and motorway driving, silent, purely electric moving off and motoring, the “booster function” for fast acceleration, recuperation and the start/stop function. These functions are activated depending on the operating state and traffic situation:
Info display indicates current operating state
The ML 450 HYBRID driving experience offers an impressive mix of high agility and balanced ride comfort under all operating conditions. A specially designed display concept enables the driver to keep track of the particular drive mode. The COMAND system display can be used to either display the current energy flow between the high-voltage battery, combustion engine and electric motors including the percentage charge state of the battery, or a fuel consumption and recuperation energy graphic. The battery charge state can also be called up in the instrument cluster. The conventional rev counter is replaced by a display which illustrates the combined drive system and recuperation output at a given moment.
The choice is yours: Economy or Sport mode
To ensure you can experience the extraordinary agility of the ML 450 HYBRID even more emphatically, apart from Economy mode, the model comes with a Sport mode, which is activated using the “E/S” button in the centre console. This operating mode provides the handling of a conventional automatic transmission with eight fixed ratios and very short shift times. The response is even more spontaneous thanks to the decidedly sporty engine and transmission control unit and the direct through-drive in the powertrain. Sport mode also recognises the driving characteristics of the driver or the particular road profile and adapts the system management function accordingly.
Classic benefits of the M-Class remain unchanged
The Mercedes-Benz M-Class models rank among the most successful premium SUVs and offer the greatest possible active and passive safety, optimum ride comfort and ease of operation, uncompromising reliability over a long period and high-quality workmanship with select materials. These attributes naturally also apply to the ML 450 HYBRID, which in these respects offers performance on a par with the conventionally powered variants. The hybrid version meets the same crash requirements and offers outstanding active safety thanks to the dynamic handling control systems ESP®, ABS or BAS and the 4MATIC permanent all-wheel-drive system. The hybrid technology has been integrated perfectly, without taking up any additional installation space which would compromise comfort or practicality. The space in the passenger compartment is unchanged; the boot capacity is as large as ever. The only external clues on the ML 450 HYBRID are the redesigned bonnet, the BlueEFFICIENCY label on the wings and the HYBRID lettering on the rear.
The ML 450 HYBRID is produced at the Mercedes-Benz plant in Tuscaloosa, Alabama, in the United States.
BlueTEC is the keyword for the future of diesel engine technology. Thanks to the highly effective exhaust treatment system developed by Mercedes-Benz, BlueTEC vehicles fulfil the strictest global emissions standards to make them the cleanest diesels in the world. With the E 250 BlueTEC concept, which was created specifically for the North American market, Mercedes-Benz is now demonstrating how BlueTEC technology in the E-Class can be combined with a four-cylinder engine with optimised fuel consumption. When fitted to the 7G-TRONIC seven-speed automatic transmission, the E 250 BlueTEC boasts fuel economy of 28 mpg U.S. in city traffic and 39 mpg U.S.on the motorway (U.S. FE standards). The E 250 BlueTEC concept fulfils the strictest emissions standards, including Bin 5 in the U.S., and would even meet the considerably toughened limits laid down in EU6 legislation not due for implementation until 1 September 2014.
The EU6 standard specifies maximum nitrogen oxide emissions that are less than half of those permitted by the current EU5 standard. The following is an overview of the current and future limits for diesel vehicles in the EU*:

For the E 250 BlueTEC, the modern 2.2 litre four-cylinder CDI engine underwent a detailed redevelopment program in order to reduce further the internal raw emissions generated by the engine and to fulfil the legislative requirements for on-board diagnostics (OBD), as well as other factors. The power unit hardware incorporates features from the series production engines, such as four-valve technology, fourth-generation common-rail piezo direct injection, 2-stage turbocharger and exhaust gas recirculation. A highly sensitive electronic engine control system reacts precisely across the full range of operating conditions to optimise the combustion process. The exhaust gas treatment system incorporates an oxidation catalytic converter mounted close to the engine, as well as a diesel particulate filter, which is located at the rear bulkhead in order to shorten its regeneration time.
At the heart of the BlueTEC system are two SCR catalytic converters (Selective Catalytic Reduction) with an “AdBlue®” injector positioned upstream. “AdBlue®” is a synthetic, aqueous urea solution that enables the nitrogen oxide (NOx) to be converted into harmless nitrogen gas in the SCR catalytic converters.
The monitoring and diagnosis of the sophisticated exhaust gas treatment process is handled by several sensors, including a differential pressure sensor, a Lambda probe plus NOx and temperature sensors.
For on-board storage of the “AdBlue®” solution, the E 250 BlueTEC has a 25 litre tank equipped with a membrane pump, valve, pressure and temperature sensors and an electrical heating unit, which prevents the 33-percent urea solution from freezing at extremely low temperatures. The tank volume is sufficient for the duration of a full service interval and is refilled as part of the regular maintenance schedule. The “AdBlue®” tank is integrated into the spare wheel well in the boot.
E 250 BlueTEC combines environmental awareness, driving fun and comfort
The combination of the powerful four-cylinder engine with SCR technology makes a convincing argument not only in terms of fuel economy and emissions, but also with impressive performance and the associated fun factor. Thanks to a pair of Lanchester balancing shafts, the concept vehicle’s powertrain boasts the exceptionally smooth characteristics expected of a Mercedes-Benz.

The AMG 6.3-litre V8 engine in the new E 63 AMG develops an output of 386 kW/525 hp and a torque of 630 newton metres, matching the outstanding figures for the SL 63 AMG. The high-performance roadster has also donated its AMG SPEEDSHIFT MCT 7-speed sports transmission to the new model. This transmission dispenses with a conventional torque converter and uses a compact, wet start-up clutch. In conjunction with the four individual driving modes, the double-declutching and RACESTART functions, the resulting direct connection to the powertrain allows an extremely emotional and highly dynamic driving experience.
The drive unit is unique in this segment, and ensures decidedly sporty performance figures: the E 63 AMG accelerates from standstill to 100 km/h in just 4.5 seconds, with a top speed of 250 km/h (electronically limited). The fast-revving, naturally aspirated engine with a displacement of 6208 cc impresses with its agile responsiveness, muscular power delivery and great flexibility. The newly composed AMG V8 sound is a thrilling accompaniment for mile after mile, while the smooth-running engine guarantees typical Mercedes long-distance comfort. A newly designed water cooling system ensures maximum endurance even under the enormous dynamic stresses of the racetrack.
Fuel consumption cut by almost twelve percent
Despite 8 kW/11 hp of additional output versus the preceding model, the fuel consumption of the new E 63 AMG has been significantly reduced: at 12.6 litres of super-premium grade petrol per 100 kilometres (NEDC combined consumption, provisional figure), the fuel consumption of the E 63 AMGis almost twelve percent lower than before, and leads the field among sports saloons developing more than 377 kW/500 hp. This progress has been made possible by a package of efficiency-enhancing measures. These include on-demand delivery of fuel and generator management with recuperation of braking energy on the overrun, both of which are standard in the new E 63 AMG. In-engine friction is also reduced by the AMG-exclusive twin-wire arc spray coating process used on the cylinder walls.
The AMG SPEEDSHIFT MCT 7-speed sports transmission also makes a decisive contribution to fuel economy: a wet start-up clutch running in an oil bath replaces the previous torque converter. This unit responds extremely rapidly, dynamically and without the losses typical of a torque converter transmission thanks to its low rotational inertia. The transmission is equipped with four driving modes: “C” (Controlled Efficiency), “S” (Sport), “S+” (Sport plus) and “M” (Manual), which can be selected using a rotary electronic switch in the AMG DRIVE UNIT. Partial suppression of individual cylinders by interrupting ignition and injection during gearshifts under full load leads to considerably faster shift times. In M mode the AMG SPEEDSHIFT MCT 7-speed sports transmission allows gearshifts to be performed in 100 milliseconds.
In the even more fuel-efficient driving mode Controlled Efficiency, the transmission shifts the gears decidedly smoothly, and the transmission control unit is programmed to perform early upshifts to keep engine speeds as low as possible. At the same time, the AMG SPEEDSHIFT MCT 7-speed sports transmission meets the most demanding requirements where driving dynamics are concerned: fast, spontaneous multiple downshifts ensure first-class agility in conjunction with the automatic double-declutching and RACE START functions: this enables the E 63 AMG driver to call on the maximum acceleration potential automatically.
Electronically controlled damping system and a new front axle
Sporty or more comfort-oriented? The driver of the new Mercedes-Benz E 63 AMG is not obliged to accept any compromises in this respect. The AMG RIDE CONTROL sports suspension copes equally well with the agile manoeuvres of the racetrack and more comfortable, sedate driving. High performance and typical Mercedes long-distance comfort go together as an extraordinary synthesis in the E 63 AMG. This is made possible by the newly developed AMG RIDE CONTROL sports suspension. While new steel spring struts are used on the front axle, the rear suspension features AMG-specific air springs. The advantage of this solution, which is exclusive to AMG, is that the front steel spring struts ensure more sensitive responses while the rear air struts with their automatic level control system keep the vehicle at a constant height irrespective of the load.
A new, electronically controlled damping system automatically varies the damping characteristics according to the driving situation, reducing the roll angle of the body. The result is instant adjustment to provide the best possible ride comfort together with the greatest possible agility. In addition the driver is able to choose between the three suspension modes of Comfort, Sport and Sport plus at the touch of a button. The E 63 AMG is also equipped with a newly developed, dedicated front axle with a 56-millimetre wider track, a tubular stabiliser, new control arms, new wheel bearings, new elastokinematics and new wheel location for more negative camber – thereby providing more grip when taking bends at speed. The AMG-specific kinematics also ensure significantly more precision. This is a highly sophisticated axle design whose principle has already proved its worth in the C 63 AMG. The rear axle likewise has more negative camber, optimised elastokinematics and a new subframe mounting for greater stability at the physical limits.
Newly developed power steering and individual 3-stage ESP®
For more direct responsiveness, the speed-sensitive rack-and-pinion steering is also a new development. The steering ratio of 14 : 1 is 22 percent more direct than in the standard production models, while a more rigid steering column plus the reconfigured characteristic mapping of the speed-sensitive servo assistance ensure better steering precision and improved road contact.
The 3-stage ESP® familiar from the SL 63 AMG and C 63 AMG enables individual settings to be selected – with clear benefits in terms of driving pleasure combined with the same, high level of handling safety. The ESP® button in the AMG DRIVE UNIT allows the driver to choose between “ESP ON”, “ESP SPORT” and “ESP OFF” – with the currently active mode shown in the central display of the AMG instrument cluster. Perfect deceleration even when driving at high speed is ensured by the AMG high-performance braking system with 360-millimetre, internally ventilated and perforated brake discs all-round. Particularly resistant, motorsports-tested composite technology is used at the front axle. Outstanding grip is ensured by the 18-inch AMG light-alloy wheels with a width of nine or 9.5 inches and mixed tyre sizes of 255/40 R 18 at the front and 285/35 R 18 at the rear.
Decidedly dynamic interior and exterior
The decidedly dynamic design of the new E 63 AMGis fully in keeping with the uncompromisingly sporty technology. The front aspect is characterised by 17‑millimetre wider wings bearing “6.3 AMG” lettering on each side, the new AMG front apron with large intake air apertures and the AMG-specific LED daytime driving lights. In conjunction with the optional Intelligent Light System, the E 63 AMG is equipped with tinted main headlamps. The striking visual presence is further enhanced by the AMG side skirts and AMG rear apron with a black diffuser insert. As a hallmark of the brand, the AMG sports exhaust system has two newly designed, chrome-plated twin tailpipes.
The newly designed interior of the E 63 AMG is an exciting blend of high-grade materials and functional sportiness. Exclusive features include the dedicated, electrically adjustable AMG sports seats with improved lateral support and the AMG sports steering wheel in a four-spoke design with AMG shift paddles. As a completely new feature exclusive to the E 63 AMG, the AMG selector lever has one-touch logic. Directly adjacent to it in the centre console is the AMG DRIVE UNIT, which provides adjustments for the MCT sports transmission, the ESP functions, the suspension setup and the AMG driving modes. Standard equipment also includes high-grade leather upholstery in three different colours, the AMG instrument cluster with an AMG main menu, door entry sills with AMG lettering and a sports pedal cluster – both in brushed stainless steel.
Even more individuality with tailor-made AMG extras
Customers requiring even more sporty individuality are catered for by the AMG PERFORMANCE STUDIO: the E 63 AMG can, for instance, be dynamically enhanced even further ex factory, with the Performance package. This includes the following:
Optional extras from the AMG PERFORMANCE STUDIO are also individually available ex factory:
The flagship AMG model in the E-Class traditionally meets the very highest expectations with respect to active and passive safety. Naturally this also applies to the new E 63 AMG: standard features include the new drowsiness detection system ATTENTION ASSIST, the unique anticipatory occupant protection system PRE-SAFE®, BAS PLUS, seven airbags and crash-responsive NECK-PRO head restraints. The safety features can be brought to a level unprecedented in this vehicle class with the Lane Keeping Assist and Blind Spot Assist systems, the PRE-SAFE® Brake with an automatic emergency braking function to bring the vehicle to a standstill, Adaptive Highbeam Assist, Night View Assist and Speed Limit Assist.
Last week we told you that Mercedes was preparing a trio of BlueZERO concept models for the North American International Auto Show in Detroit, each of which featured a distinct alternative power source. In the BlueZERO E-Cell, power came by way of a lithium-ion electric drive; in the BlueZERO E-Cell Plus, a lithium-ion electric drive plus an internal combustion was present; and in the BlueZERO F-Cell, a fuel cell system was the primary means of thrust (their operating ranges varied from 75 miles to just under 450 miles).
This week, Mercedes has confirmed that the three BlueZERO concept vehicles are indeed set to premier at Detroit’s North American International Auto Show, with the three models the latest demonstration of the company’s focus on developing “modular powertrain technologies.” Each are based on the same lightweight sandwich-floor architecture (first introduced on the A-Class and then B-Class some ten years ago), with their goal being to demonstrate how in a single platform, Mercedes already has the ability to offer a varying range of alternative drive technologies based on individual customer requirements.
According to Daimler CEO Dr. Dieter Zetsche: “The flexible BlueZERO concept allows electromobility for every requirement and highlights the fact that Mercedes-Benz is the world’s only car manufacturer to already have in place all the key technologies for electric cars offering full everyday practicality.”
Dr Thomas Weber, the member of the Daimler AG Board of Management responsible for corporate research and development at Mercedes-Benz Cars, adds: “Our modular system allows different drive configurations for every customer requirement. The modified sandwich-floor platform provides the perfect basis for a wide model range with electric drive systems. We are also developing a new, additional platform for future compact models with power units based on optimised internal combustion engines. The intelligent networking of both architectures enables us to develop our product portfolio extremely flexibly and efficiently. From 2009, we will be producing the first Mercedes fuel-cell cars on a small scale. Small-scale production of Mercedes-Benz cars with battery-electric drive alone will then commence in 2010. This means we are extremely well equipped for the future.”
Or, to put it simply, Mercedes would like to formally state that they have succeeded in creating a trio of alternatively-powered A-/B-Class models, but in all probability, you won’t be getting your hands on one anytime soon.
For more information regarding the Mercedes-Benz BlueZERO concept vehicles, keep reading for the official press release and photos (click to enlarge).
According to the all-seeing eyes and all-knowing minds at Auto Motor und Sport, Mercedes is on the verge of introducing three new alternatively powered “BlueZero” concept vehicles – a feat they’ll perform at next month’s North American International Auto Show in Detroit (January 11th-25th; get your tickets while they’re hot). Titled the Mercedes-Benz BlueZero E-Cell, the BlueZero E-Plus Cell and the BlueZero F-Cell, the three models make use of a lithium-ion electric drive, a lithium-ion electric drive plus an internal combustion engine and a fuel cell system, respectively.
In the Mercedes BlueZero E-Cell (powered only by a lithium-ion electric drive system, remember), range is expected to be about 75 miles. In the fuel cell powered Mercedes BlueZero F-Cell, range is expected to double, thanks to the electric motor’s ability to act as a generator, thus charging the battery during various stages of operation (much like the S400 BlueHYBRID). And in the BlueZero E-Plus Cell, a rear-mounted three-cylinder turbo petrol engine borrowed from the smart fortwo is rumored to give the part gas, part electric model an operating range of some 372 miles, with another 75 miles on tap operating in purely electric mode.
How this information was derived isn’t clear, but judging by the commonality of Mercedes’ various “leaks,” I’d expect when the North American International Auto Show opens its doors next month the majority of Auto Motor und Sport’s assessments will be spot on.
Time will tell, but in the meantime, keep scrolling to see a number of photos depicting one of the Mercedes BlueZero concept vehicles (click to enlarge), then head over to Auto Motor und Sport where you can check out their full article translated from German for your reading entertainment.
