The new Mercedes-Benz SL 63 AMG: High-performance dream car with efficiency credentials

The stage is set for the new Mercedes-Benz SL 63 AMG. The new version of the high-performance Roadster impresses on several counts: systematic lightweight construction, a boost in output and driving dynamics, and 30 percent lower fuel consumption and emissions. Thanks to an all-aluminium bodyshell, similar to that of the SLS AMG super sports car, the vehicle weight has been reduced by 125 kilograms. With a kerb weight of 1845 kilograms and an output of 395 kW (537 hp) or 415 kW (564 hp), the new model has the perfect recipe for unparalleled dynamism and a superior driving experience. A further boost in performance comes courtesy of a winning combination: enhanced AMG sports suspension based on Active Body Control (ABC), new AMG speed-sensitive sports steering, the AMG high-performance composite braking system and the AMG SPEEDSHIFT MCT 7-speed sports transmission. The expressive front section is dominated by the new "twin blade" radiator grille and the front apron's lower cross strut in silver chrome. An enticing mix of stylish design, extensive standard equipment and a high safety level.

Supreme performance and high efficiency: the SL 63 AMG is available with a choice of two power ratings for the first time. The AMG 5.5-litre V8 biturbo engine delivers 395 kW (537 hp) and 800 Nm of torque. If the AMG Performance package is specified, drivers will have 415 kW (564 hp) and 900 Nm at their disposal – more power than any other competitor in this segment. The result is phenomenal performance, as underlined by the acceleration times from 0 to 100 km/h in 4.3 or 4.2 seconds respectively.

A speed of 200 km/h is reached in 12.9 or 12.6 seconds respectively. Top speed is electronically limited to 250 km/h, although this increases to 300 km/h (likewise electronically limited) with the AMG Performance package on board. NEDC combined consumption comes in at 9.9 litres per 100 kilometres for both power ratings – a full 4.2 litres or 30 percent less than for the outgoing model.
The eight-cylinder powerplant with the abbreviation M 157 features a combination of innovative high-tech components – for high power output – and delivers exemplary, low fuel consumption. In addition to spray-guided direct petrol injection, the engine boasts an all-aluminium crankcase, twin turbochargers, four valves per cylinder with camshaft adjustment, air/water intercooling, alternator management and an ECO start/stop function. The weight-optimised AMG sports exhaust system with two chromed twin tailpipes produces a distinctive engine sound.


The key data at a glance
Intelligent lightweight construction with aluminium bodyshell and carbon fibre

Intelligent lightweight construction is one of the major factors behind the low fuel consumption figures. The SL 63 AMG is based on a lightweight all-aluminium bodyshell similar to that of the SLS AMG super sports car. Compared with the preceding model which featured a steel construction, this design not only delivers a significant weight saving of around 110 kilograms, it also greatly enhances rigidity, safety and comfort. Intelligent lightweight construction also means that the components have been optimised in line with their specific purpose. Various types of processing are used for the aluminium components, for instance, which are produced as permanent mould castings (reusable metallic casting mould) or vacuum die castings before being processed into extruded sections or used as sheet aluminium with varying wall thicknesses. The result is high rigidity, high safety and improved vibration characteristics. For the cover behind the tank, the designers use even lighter magnesium material in some cases. High-strength steel tubes are integrated into the A-pillars for safety reasons.


The boot lid helps to further trim the weight. For the first time on a volume-produced model, the inner support is made from lightweight carbon-fibre composite material. The extremely rigid carbon-fibre component is bonded to the plastic outer shell, resulting in a weight saving of five kilograms compared with a conventional boot lid – an innovative solution that is being pioneered with the SL 63 AMG. This raft of innovative lightweight design measures means that, at an EC kerb weight of 1845 kilograms, the new SL 63 AMG is 125 kilograms lighter than the model it is replacing.


AMG sports suspension based on Active Body Control


The lightweight design measures are not just limited to the body of the SL 63 AMG, however, as the steering knuckles and spring links on the four-link front suspension and almost all of the multi-link independent rear suspension's wheel location components are made of aluminium. The reduction in unsprung masses enhances both agility and the response characteristics of the spring-and-damper units.


Mercedes-AMG is remaining faithful to the ABC active spring and damper system: the new SL 63 AMG is equipped with an enhanced version of the AMG sports suspension based on Active Body Control as standard. During the design, development and testing phases, the focus was firmly on driving dynamics and performance. To enable greater agility and faster cornering speeds, the SL 63 AMG has more negative camber all round and fully revised elastokinematics. Exceptionally sporty characteristics with reduced roll angles and firm body damping ("Sport") or more comfort-oriented settings for a high level of comfort on long journeys ("Comfort") can be selected at the push of a button.


Equipped with the new, electro-mechanical AMG speed-sensitive sports steering, the flagship AMG model impresses with its fleet-footed, agile cornering and exceptional feedback at the critical limits. The steering has a constant and more direct ratio, and variable power assistance which adjusts in line with the suspension settings. Further standard equipment includes 3-stage ESP®, a speciality exclusive to AMG with "SPORT Handling" mode for particularly keen drivers, while options available from the AMG Performance Studio include an AMG rear axle differential lock and AMG performance suspension.


Individuality: AMG SPEEDSHIFT MCT 7-speed sports transmission


Power transmission can likewise be adapted to specific requirements, as the AMG SPEEDSHIFT MCT 7-speed sports transmission has four modes to select from: "C" (Controlled Efficiency), "S" (Sport), "S+" (Sport plus) and "M" (Manual). In "C" mode, the ECO start/stop function is active and switches off the eight-cylinder engine when the vehicle is at a standstill. Plus the transmission characteristics are tangibly soft, with smooth and early gear changes. Second gear is generally used as the starting gear in this mode.


The engine and transmission are far more agile in "S", "S+" and "M" mode; in addition, the ECO start/stop function is deactivated. Partial suppression of the cylinders proves perfect for a committed driving style: briefly and precisely interrupting ignition and injection under full load leads to even faster gearshifts than before. A welcome side effect of this is the emotive sound impression. An automatic double-declutching function for downshifting and the RACE START function are also included as standard with the AMG SPEEDSHIFT MCT 7-speed sports transmission.


Newly developed AMG high-performance composite braking system


Maximum performance is also a top priority when it comes to braking: the newly developed AMG high-performance composite braking system features 390 x 36 mm composite discs with six-piston fixed callipers at the front and 360 x 26 mm integral discs with single-piston floating callipers at the rear. An electric parking brake is fitted as standard, while options available from the AMG Performance Studio include red-painted callipers to denote the AMG Performance package and the even more high-performance, weight-optimised AMG ceramic high-performance composite braking system as seen on the SLS AMG.


The SL 63 AMG leaves the factory fitted with five-twin-spoke AMG light-alloy wheels painted in titanium grey with a high-sheen finish, complete with 255/35 R 19 front and 285/30 R 19 rear tyres. Multi-spoke AMG forged wheels painted in titanium grey and with a polished finish from the AMG Performance Studio with 255/35 R 19 front and 285/30 R 20 rear tyres – also available in matt black including a rim flange with a high-sheen finish – help to reduce the unsprung masses.


Design: dominated by the new AMG brand face


SLS AMG Roadster, SLK 55 AMG and SL 63 AMG – as the latest addition to the AMG Roadster family, the flagship V8 model displays the hallmark styling elements of a superior high-performance car from Affalterbach. The new AMG brand face comprises the twin blade radiator grille and the lower cross strut in the front apron - both featuring a solver chrome finish. The dynamically distinctive AMG bodystyling, meanwhile, comprises the front apron with large air dams and AMG-specific LED daytime driving lights. Other particularly eye-catching features include the side sill panels and the "V8 BITURBO" logos on the vent grilles with fins in silver chrome. At the rear, the AMG spoiler lip, the two chromed twin tailpipes of the AMG sports exhaust system and the diffuser-style rear apron with body-coloured insert draw the design to a fitting conclusion.


Vario-roof: MAGIC SKY CONTROL as an option


The sixth-generation SL retains the electrohydraulically operated vario-roof which can be retracted into the boot to save space, enabling the SL to be transformed into a roadster or a coupé, as the mood takes the driver and depending on the weather, in under 20 seconds. In contrast to the outgoing model, there are three versions to choose from for the new SL: painted roof, glass roof or the unique panoramic vario-roof with MAGIC SKY CONTROL. Its transparency can be switched to light or dark at the push of a button.


Interior: a feast for all the senses


The SL 63 AMG interior is likewise inspired by the SLS AMG and offers a feast for all the senses: the four air vents styled like jet engines, the E-SELECT lever and the AMG DRIVE UNIT are all reminiscent of the super sports car's styling. Standard equipment includes AMG sports seats in nappa leather with their own V8 seat upholstery layout and AMG badges in the seat backrests, a multicontour function and seat heating, as well as AMG carbon-fibre trim, AMG illuminated door sill panels, ambient lighting and an IWC-design analogue clock. One of the stand-out details on the AMG Performance steering wheel is the AMG logo in the lower metal insert. The sportily designed AMG instrument cluster provides a wealth of information with its TFT colour monitor, AMG start-up display, AMG main menu and RACETIMER. Outstanding material quality and high-calibre workmanship underline the attention to detail paid by the Mercedes and AMG experts.

The New Mercedes-Benz SLS AMG Roadster: Perfect open-top performance - III


Perfect proportions and purist lines for an exciting presence: the design of the SLS AMG Roadster stirs the emotions. Whether with the soft top open or closed, the Roadster exudes passionate sportiness and sheer exclusivity. The new super-sports car reinterprets the breathtaking lines of the iconic Mercedes-Benz 300 SL Roadster from the 1950s, and continues the legend of exciting sports cars bearing the Mercedes star.


Memories of the legendary Mercedes-Benz 300 SL are also rekindled by the hallmark wide radiator grille with the large Mercedes star and the wing-shaped cross-fin. The three-dimensional, sculptured front-end with its low-set, arrow-shaped front apron set well into the sides lends the SLS its powerful stance on the road. Six large cooling air intakes and the vertically arranged headlamps set well to the outside with their alluring inner ambience provide a dominant aura, and are also stylistically reminiscent of the 300 SL Roadster. The central bi-xenon low-beam headlamp with its metallic wing section is framed by two LED indicator strips at the top and by the LED daytime running lamps at the bottom.

Sheer dynamism is not only suggested by the almost two-metre long bonnet, the low greenhouse set well to the rear and the short rear end with the extending rear aerofoil, but also by the long wheelbase, wide track and large wheels. The short overhangs characterise the athletic proportions as strongly as the overall engineering concept for this super-sports car, with its low-mounted front-mid engine and dual clutch transmission in a transaxle configuration.

Design influences from aircraft construction

Allusions to aircraft construction come courtesy of the prominent Mercedes star, whose tubular section is reminiscent of the air intake on a jet engine when viewed from the side, as well as the long bonnet: as the eye is drawn forward, so the observer becomes more aware of the curved bonnet contour. The design of the four fins with their Silver Shadow finish adorning the two air outlet grilles on the end of the bonnet creates the same visual impression. These aircraft-style lines also visually accelerate the air that flows past – and make the SLS AMG appear extremely dynamic even while stationary.

The fins on the bonnet are also to be found on the vehicle flanks, and here too the afficionado will rediscover a typical design feature of the 300 SL Roadster. The "6.3" lettering integrated between the fins is a clear reference to the large, naturally aspirated V8 engine. A stylish character line emerges from the side air outlet, combining visual appeal with power in combination with the dramatic effect of the flank surface. Extraordinarily appealing and unmistakable, the only 1261-millimetre high passenger compartment with its high beltlines, flat side windows and steep windscreen is in the nature of an observation post. When closed, the low fabric soft top accentuates the purist overall impression and embodies classic roadster design. When opened, the soft top is deposited behind the seats in a Z-configuration to preserve the harmonious lines. The three soft top colours of black, red and beige are available to suit the choice of nine exterior and six interior colours.

Side view dominated by muscle and shoulder

Viewing the SLS from the side, the eye is drawn to the prominent vehicle shoulder, which stretches from the front to the rear like a taut muscle. Dynamism is also enhanced by exterior mirrors mounted on the beltline. Distinctive 19-inch (front) and 20-inch (rear) light-alloy wheels fill the flared wheel arches, which stand out prominently from the flank. Three different wheel variants all provide a good view of the large, high-performance composite brakes. Seen from above, a prominent, uninterrupted line runs from the muscle to the rear. This styling feature is also picked up on the bonnet, where the eye follows a distinctive contour. On the right, a sporty filler cap of solid metal provides another visual highlight.

Rear view that emphasises width

Dynamism and power are also suggested by the rear view of the SLS AMG Roadster. The gently sloping boot lid creates an impression of width, as do the pronounced shoulder, the closed soft top with its wide glass rear window and the flat rear light clusters. Featuring LED technology and two slim chrome inserts, the horizontally divided light clusters provide interesting perspectives. Wing-shaped LED lighting elements make for a distinctive and striking night design. Unlike in the SLS AMG Coupé, the third brake light is integrated into the boot lid.

Similarly inspired by motor racing are the black diffuser insert, the low, centrally located Formula 1-style LED foglight/reversing light and the two chromed tailpipes of the sports exhaust system. The strikingly tapered rear apron provides an unimpeded view of the wide rear wheels, lending the SLS its self-assured stance on the road. The spoiler integrated in the boot lid is automatically deployed from a speed of 120 km/h to ensure optimum stability at high speeds. As the aerials for radio, navigation and telephone reception are invisibly integrated into the boot lid, they do not disrupt the car's silhouette.

Interior reminiscent of an aircraft cockpit and motor racing functionality

Authentic materials and outstanding precision with respect to material quality and standard of finish: the interior of the SLS AMG Roadster already thrills at first sight. As in the gullwing model, the Roadster cockpit creates associations with an aircraft cockpit. The characteristic styling feature is the dashboard, whose powerful and dramatic wing shape makes for an impression of width. Strikingly integrated into the dashboard are the galvanised air vents with their adjustable, cruciform nozzles and Silver Shadow finish – their shape reminiscent of a jet's engines. The instrument cluster with its LED upshift indicator and two white backlit dial instruments adds another decidedly sporty touch with its metallic Silver Shadow finish. The silver dials have red-lit needles and a 360‑ km/h scale. As a central feature of the cockpit, the COMAND APS multimedia system is integrated between the two centre air vents.

The elongated centre console in matt metal similarly picks up on the design theme of an aircraft cockpit. It is home to the AMG DRIVE UNIT, which is inclined towards the SLS driver and allows him to choose his personal vehicle setup. The E-SELECT shift lever, whose styling recalls the thrust control of a jet, controls the AMG SPEEDSHIFT DCT 7-speed sports transmission. The solid metal selector lever is lined with high-grade leather bearing an embossed AMG emblem. The attractively integrated control unit for the electric soft top is located in the rear section of the centre console.

Numerous controls are precision-made from solid metal, with a high-sheen Silver Shadow surface. On request the centre console and other interior features such as the door sill panels, interior door trim and seat backrest trim are available in carbon-fibre. Alternatively AMG trim in high-gloss black is available for the centre console.

Authentic cockpit atmosphere in the interior

The concave shape of the interior door panels and the high beltline make for an authentic cockpit atmosphere. Together with the wide centre tunnel extending well to the rear, they reinforce the impression of safety and security. Topstitching and contrasting seams, as well as fine designo leather on the sports seats, create a luxurious impression and accentuate the hand-finished look. All surfaces such as the interior door panels and armrests are softly padded for a very pleasant feel.

Dynamic steering wheel design and six different leather colours

An authentic racing car touch is provided by the AMG Performance steering wheel with a diameter of 365 millimetres. The rim has a flattened lower section and an oval cross-section, plus perforated leather in the ergonomically formed grip area, for outstanding vehicle control. The shift paddles and lower insert are of metal. The unmistakable attention to detail for which Mercedes designers are known is very evident in the tasteful colour combinations in the interior. Six different single-tone designo leather colours are available to meet individual preferences: black, espresso brown, sand, classic red, light brown and porcelain. The sports seats with integrated head restraints and sporty transverse fluting are upholstered in designo leather, with a metal AMG badge in the backrests. Two-tone designo Exclusive leather seats are also available in espresso brown/black, classic red/black, sand/black and porcelain/black. If light brown is chosen as an interior colour, the sports seats are upholstered in natural leather with particularly high-quality woven leather on the centre seat panels.

The A-pillars are lined in anthracite Alcantara, heightening the functional, purist motor sports atmosphere. These surfaces are complemented with the sporty carpeting and floor mats bearing the AMG logo.

The New Mercedes-Benz SLS AMG Roadster: Perfect open-top performance - I


Second AMG dream car after the gullwing model - The SLS AMG Roadster: open-top sensuality

AMG, the high-performance brand within Mercedes-Benz Cars, is presenting a new dream car: the SLS AMG Roadster. Two years after the sensational launch of the gullwing model at the 2009 International Motor Show (IAA), the open-top variant of this super sports car is now set to follow.



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 Källenius, 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 gullwing model has already thrilled sports car fans all over the world, and now the open-top version is bound to cause a sensation."


Key data at a glance:

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 gullwing 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 gullwing 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 six 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 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. Leather-lined roll-over bars with integrated mesh 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:

- Real-time display of engine oil, coolant and transmission fluid temperature
- Real-time display of engine output, torque and accelerator position
- Real-time display of individual tyre pressures
- Real-time display of acceleration time from 0-100 km/h (alternatively: quarter-mile)
- Real-time display of lateral and linear acceleration combined with braking performance and accelerator position, including memory function
- Recording of individual lap times on a closed-off racetrack, with sector times and memory function
- Integration of Drive Unit functions to save setup data to memory and initiate RACE START


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.

In order to achieve handling dynamics identical to those of the Coupé, 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. To maintain stability despite the omission of the Coupé roof and gullwing doors, 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 optional 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 gullwing 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. For maximum occupant safety, ultra-high-strength, heat-formed steel is used 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 gullwing 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, reaches 200 km/h in 11.3 seconds and has a top speed of 317 km/h (electronically limited) – which means that the Roadster has a performance comparable to the gullwing 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. Like the gullwing variant, the SLS AMG Roadster consumes 13.2 litres per 100 kilometres (NEDC combined), corresponding to CO2 emissions of 308 grams per kilometre. Efficiency-enhancing measures include the familiar AMG-exclusive, friction-optimised NANOSLIDE 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.

Dual 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 dual 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 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 and transmission 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", "SPORT Handling Mode" 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 available 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 market launch of the Mercedes-Benz SLS AMG Roadster will start in October 2011. The purchase price is € 195,160 (incl. 19% VAT).
