The stage is set.
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 compound brake system and the AMG SPEEDSHIFT MCT 7-speed sports transmission. An enticing mix of stylish design, extensive standard equipment and a high safety level.
Ola Källenius, CEO at Mercedes-AMG GmbH: "The new SL 63 AMG is yet another masterpiece from Mercedes-AMG. Be it driving dynamics, lightweight construction or efficiency – the SL 63 AMG represents a giant leap forward. Following on from the SLS AMG Roadster and the SLK 55 AMG, it now makes our unrivalled roadster family practically complete."
Superior performance and high efficiency: the SL 63 AMG is available with a choice of two power outputs for the first time. The AMG 5.5-litre V8 'biturbo' (twin-turbocharged) engine delivers 395 kW (537 hp) and 800 Nm of torque. If the AMG Performance package is specified, these figures rise to 415 kW (564 hp) and 900 Nm – more power than any other competitor in this segment. The result is high-calibre performance, as underlined by the acceleration 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 250 km/h (electronically limited), although this rises 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 outputs – a full 4.2 litres or 30 percent lower 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 it 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.
