Geneva Auto Show: SL 63 AMG, SLK 55 AMG and ML 63 AMG
- Mercedes-Benz at the 2012 Geneva Motor Show: Two world premieres and three European premieres in Geneva
- SL 63 AMG, SLK 55 AMG and ML 63 AMG: High performance to the power of three
Mercedes-AMG GmbH is offering three new high-performance cars that cater to a broad spectrum of requirements in the shape of the SL 63 AMG, SLK 55 AMG and ML 63 AMG. The two prestigious eight-cylinder roadster models and the mighty SUV distinguish themselves with efficient drive systems, breathtakingly dynamic performance and emotion-charged design.
The stage is set for the new Mercedes-Benz SL 63 AMG. The latest version of the high-performance roadster impresses on several counts: systematic lightweight construction, increased output and enhanced driving dynamics, all combined with a 30 percent reduction in fuel consumption and emissions. Thanks to an all-aluminium bodyshell, similar to that of the SLS AMG supercar, the vehicle has shed 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 boasts the perfect ingredients for unparalleled dynamism and a sublime driving experience that is truly unique.
A further boost in performance comes courtesy of a winning combination: a further improved AMG sports suspension based on Active Body Control, new AMG speed-sensitive sports steering, the AMG high-performance compound braking system and the AMG SPEEDSHIFT MCT 7-speed sports transmission. An enticing mix of stylish design, extensive standard equipment and a high level of safety.
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 Newton metres of torque. If the AMG Performance package is specified, drivers will have 415 kW (564 hp) and 900 Newton metres 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 and to 200 km/h 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 M157 features a combination of innovative high-tech components for high power output and scintillating power delivery on the one hand and remarkably low fuel consumption on the other. Besides spray-guided direct petrol injection, the engine features an all-aluminium crankcase, twin turbochargers, four valves per cylinder with camshaft adjustment, air-to-water intercooling, generator management and an ECO start/stop function. The weight-optimised AMG sports exhaust system with two sets of chromed twin tailpipes produces a distinctive soundtrack.
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 built around a lightweight all-aluminium bodyshell similar to that of the SLS AMG supercar. Compared to the outgoing model, this design not only delivers a significant weight saving of around 110 kilograms, it also greatly enhances rigidity, safety and comfort. 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. The extremely rigid carbon-fibre component is bonded to the plastic outer shell, resulting in a weight saving of five kilograms compared to a conventional boot lid.
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 has retained the ABC active suspension and damper system: the new SL 63 AMG is equipped as standard with the AMG sports suspension based on Active Body Control, but in a further improved version. Exceptionally sporty characteristics with reduced roll angles and firm body damping ("Sport") or a more comfort-oriented setting for a high level of comfort on long journeys ("Comfort") can be selected at the push of a button. This together with the new electromechanical AMG speed-sensitive sports steering endows the flagship AMG model with fleet-footed, agile cornering and exceptional feedback at the limits of performance. The steering has a constant, more direct ratio, together with variable power assistance that adjusts depending on the suspension setting.
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 at all times and switches off the eight-cylinder engine when the vehicle is stopped. Meanwhile, the RACE START function allows lightning quick acceleration from a standing start.
The brakes are designed to deliver maximum performance too: besides the newly developed AMG high-performance composite braking system, there is also the alternative of the AMG ceramic high-performance composite braking system familiar from the SLS AMG. The SL 63 AMG leaves the factory fitted with AMG five-twin-spoke light-alloy wheels painted titanium grey with a high-sheen finish and shod with tyres size 255/35 R 19 at the front and 285/30 R 19 at the rear. AMG multi-spoke forged wheels from the AMG Performance Studio with 255/35 R 19 front and 285/30 R 20 rear tyres help to reduce the unsprung masses. They are also available in matt black including a rim flange with a high-sheen finish.
Design: stylish, supreme, dynamic
The SL 63 AMG is the latest addition to the AMG roadster family and displays the hallmark styling elements of a supreme high-performance car from Affalterbach: the dynamic, distinctive AMG bodystyling comprises the front apron with large cooling air intakes, AMG-specific LED daytime running lamps and a lower cross strut in silver chrome. Among the particularly eye-catching features are the new AMG radiator grille with a double louvre in silver chrome, 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.
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 supercar's styling. Standard equipment includes AMG sports seats in single-tone or two-tone 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.
SLK 55 AMG: top figures in all disciplines
The Mercedes-Benz SLK 55 AMG is the most powerful SLK of all time. Its newly developed naturally aspirated AMG 5.5-litre V8 engine with cylinder shut-off system combines ultimate performance with minimised fuel consumption. With a maximum output of 310 kW (422 hp) and peak torque of 540 Newton metres, the SLK 55 AMG outperforms all of its direct competitors. The SLK 55 AMG accelerates from zero to 100 km/h in 4.6 seconds, and reaches a top speed of 250 km/h (electronically limited). Its fuel consumption of 8.4 litres per 100 kilometres (NEDC combined) and CO2 emissions of 195 grams per kilometre are some 30 percent lower than the figures for its predecessor.
Exclusive combination of advanced technologies
The high-tech M 152 powerpack enthrals with an unrivalled combination of advanced technologies. No other petrol engine features direct injection at a pressure of 200 bar, spray-guided combustion and piezoelectric injectors, all in conjunction with map-controlled cylinder shut-off, an all-aluminium crankcase honed using a special "spectacle" technique, four valves per cylinder with continuous camshaft adjustment, a high compression ratio of 12.6:1, ECO stop/start function and generator management – while revving to a maximum speed of over 7000 rpm. All of these measures result in an optimum efficiency factor, which is a precondition for high fuel efficiency and low exhaust emissions.
Borrowed from Formula 1: AMG Cylinder Management cylinder shut-off system
Engine efficiency is significantly improved in particular by the AMG Cylinder Management cylinder shut-off system that has been newly developed by Mercedes-AMG: under partial load conditions, cylinders two, three, five and eight are shut off, resulting in considerable fuel savings. This technology is employed in similar form in the approx. 750 hp V8 engines used in Formula 1. The cylinder shut-off function is available over a wide engine speed range from 800 to 3600 rpm if the driver has selected transmission mode "C" - Controlled Efficiency. The ECO start/stop function and generator management further contribute to the low fuel consumption figures. For the first time, AMG is using a sports exhaust system featuring an exhaust flap on each side. This technology resolves the conflict of objectives between producing an emotion-stirring sound when driving in a sporty manner and a more discreet engine tone in the partial load range.
Perfect combination: highly dynamic driving and pleasurable cruising
The AMG sports suspension with Torque Vectoring Brakes and AMG Direct-Steer system provides remarkable lateral dynamics and agile handling, together with the comfort on long journeys that Mercedes is renowned for. The AMG Direct-Steer system is the perfect complement to the Torque Vectoring Brakes: compared with standard steering, it enhances handling and agility while also reducing the effort required when parking.
AMG five-spoke light-alloy wheels painted in titanium grey with a high-sheen finish, size 8 x 18 (front) and 9 x 18 (rear), are shod with 235/40 R 18 and 255/35 R 18 wide-base tyres respectively. Alternatively, customers have the choice of two further design variants from the AMG Performance Studio: AMG multi-spoke light-alloy wheels painted in either a titanium grey or matt black finish. The AMG high-performance braking system stands out for its outstanding responsiveness, short stopping distances and excellent fade resistance.
The optionally available AMG Handling package injects the SLK 55 AMG with even greater sportiness. It comprises an AMG Performance suspension with stiffer tuning, an AMG rear-axle differential lock, composite brake discs at the front and a three-spoke AMG Performance steering wheel in nappa leather with Alcantara® inserts in the grip areas.
Unmistakable: uniquely styled design and appointments
Classic roadster proportions with typical AMG design traits as well as a hint of SLS AMG – that's how the SLK 55 AMG can be summed up visually. The new AMG front apron has large air intakes and AMG-specific LED‑ daytime running lamps. Inspired by the SLS AMG supercar, the wide radiator grille features a large, centrally positioned Mercedes star. On the SLK 55 AMG, the louvres in the radiator grille and the front apron's cross strut are painted in a high-gloss black finish. Headlamps with dark edging and darkened tail lights also come as standard on the top-of-the-range V8 model. Further styling highlights include the AMG rear apron with black diffuser insert, the AMG sports exhaust system with two chromed twin tailpipes and the spoiler lip on the boot lid.
The interior design is likewise reminiscent of the SLS AMG Roadster: the four air vents in the style of jet engines evoke associations with the supercar, as does the centre console finished in brushed aluminium. The AMG Performance steering wheel, with its flattened top and bottom sections, also boasts metal trim, aluminium shift paddles and grip areas wrapped in perforated leather. The AMG sports seats with their individual seat upholstery layout come as standard with combined ARTICO man-made leather/black fabric upholstery and high-quality AMG badges in the backrests.
ML 63 AMG: efficiency and superlative performance
The new Mercedes-Benz ML 63 AMG stands for efficiency and performance, exclusivity and a superlative driving experience. Burning 11.8 litres of fuel per 100 kilometres (NEDC combined, 276 g CO2/km), the high-performance SUV undercuts its predecessor by 28 percent. The basis for the low fuel consumption and top-class performance is provided by the AMG 5.5-litre V8 biturbo engine, featuring spray-guided direct petrol injection with piezoelectric injectors, ECO start/stop system, an all-aluminium crankcase, four valves per cylinder with camshaft adjustment, air-to-water intercooling and generator management. The eight-cylinder unit extracts a maximum power output of 386 kW (525 hp) and 700 Newton metres of torque from its displacement of 5461 cc. In conjunction with the AMG Performance package, these figures rise to 410 kW(557 hp) and 760 Newton metres. Both variants of the ML 63 AMG deliver sports car-like performance: the sprint from 0 to 100 km/h takes 4.8 seconds and 4.7 seconds respectively, while top speed stands at 250 km/h (electronically limited).
Efficient and variable: AMG SPEEDSHIFT PLUS 7G-TRONIC
Power transmission to all four permanently driven wheels is handled by the AMG SPEEDSHIFT PLUS 7G-TRONIC. Featuring three modes and an automatic double-declutching function for downshifting, this seven-speed automatic transmission is fascinatingly versatile. In "Controlled Efficiency" (C) mode, the ECO start/stop function is active, shutting down the eight-cylinder engine whenever the vehicle is stopped.
As previously, Mercedes-AMG deploys a specially designed transfer case for the 4MATIC permanent all-wheel drive, which distributes the drive power to the front and rear axle at a ratio of 40 : 60 in the interests of dynamic handling. The AMG RIDE CONTROL sports suspension with AIRMATIC package – consisting of air suspension, special damper struts, automatic level control and Adaptive Damping System (ADS) – is combined for the first time with the ACTIVE CURVE SYSTEM for active roll stabilisation. This system, which comes as standard, employs active anti-roll bars on the front and rear axles to reduce the body's roll angle during cornering. Apart from enhanced agility and driving pleasure, the system has the additional effect of increasing handling stability and therefore safety, particularly at higher speeds.
The electromechanical AMG speed-sensitive sports steering varies the power assistance depending on the vehicle's speed and also helps to save fuel. The AMG high-performance braking system provides for the shortest possible braking distances and high fade resistance. The ML 63 AMG rides as standard on AMG 5-spoke light-alloy wheels measuring 9 x 20, painted titanium grey with a high-sheen finish and fitted with size 265/45 R 20 tyres. Tyres in 295/35 R 21 format on 10 x 21 AMG light-alloy wheels are optionally available.
Specific AMG bodystyling with trim in matt silver chrome
The design of the new ML 63 AMG exudes self-confidence, athleticism and power. Under the radiator grille with louvres painted in high-gloss black and the Mercedes star in the centre is a large cooling air intake. Fitted at the bottom of the AMG front apron is a trim strip in matt silver chrome, which lends the front a wider appearance while harmonising with the surrounds of the daytime running lamps in the side cooling air intakes. Another eye-catching feature is the AMG rear apron with its simulated black air outlet openings and trim strip in matt silver chrome. In contrast to the other M-Class variants, the ML 63 AMG features two sets of visible chromed twin tailpipes.
High-class, sporty interior
A sporty character and supreme quality define the interior of the high-performance SUV from AMG. This is embodied in the electrically adjustable AMG sports seats offering pronounced lateral support just as much as in the four-spoke AMG Performance steering wheel. The standard leather upholstery includes contrasting double topstitching as well as AMG badges in the backrests of the front seats and the outer rear seats.
