Weight:4299 lbs

Affalterbach – Mercedes-AMG is embarking on the 2012 roadster season in inimitably dynamic style: following on from the recent launch of the SL 63 AMG, the top eight-cylinder model, there now comes the presentation of the new Mercedes-Benz SL 65 AMG, the V12 roadster in the line-up from the Stuttgart-based manufacturer.

The AMG 6.0-litre V12 "biturbo" (twin-turbocharged) engine develops a maximum output of 463 kW (630 hp) and maximum torque of 1000 newton metres. The result: exceptional performance, impressive power delivery and effortlessly superior dynamics. As with the SLS AMG super sports car, the use of an all-aluminium bodyshell results in a drastic reduction in weight.

The new SL 65 AMG is some 170 kilograms lighter than before. The expressive front section is dominated by the new "twin blade" radiator grille and the front apron's lower cross strut in high-sheen chrome.

An important aspect of the new model is the intelligent lightweight construction which also contributes to reducing the fuel consumption. At 11.6 litres per 100 kilometres (NEDC combined) it represents a saving of 2.4 litres or 17 percent compared with the previous SL 65 AMG and simultaneously establishes a new benchmark in the twelve-cylinder petrol engine segment. A major role in the reduced fuel consumption figures is played by the AMG SPEEDSHIFT PLUS 7G-TRONIC transmission, the ECO start/stop‑function, in-engine measures to optimise efficiency and alternator management. Despite the significantly reduced fuel consumption, the maximum output of the AMG V12 6-litre biturbo engine is up from 450 kW (612 hp) to 463 kW (630 hp).

The maximum torque is 1000 newton metres.

The unrivalled performance figures of the new SL 65 AMG translate into an exceptional driving experience: acceleration from 0 to 100 km/h takes 4 seconds with the 200 km/h mark attained after just 11.8 seconds. The top speed is 250 km/h (electronically limited). As well as offering stunning acceleration, the AMG twelve-cylinder biturbo engine impresses with its smooth running characteristics and its distinctive AMG V12 sound. It is a performance that reconciles effortless superiority and stylishness to perfection.

AMG 6-litre V12 biturbo engine with new technology

The AMG 6-litre V12 biturbo engine with the designation M 279 is based on the M 275 engine used previously and has been comprehensively revised for the new SL 65 AMG. New exhaust gas turbochargers with an increased spiral cross-section, new manifolds and wastegate ducts with optimised flow characteristics increase the engine output by 13 kW (18 hp).

The multi-spark ignition with twelve double ignition coils not only results in smoother running, but also enables even more effective combustion in combination with a new engine management system with higher performance and optimised cylinder heads. The resulting reduction in exhaust emissions is also due to a large extent to the optimised catalytic converter system. The newly developed AMG sports exhaust system, which has a pipe layout with enhanced flow characteristics, is 3.2 kilograms lighter as a result of a reduction in the wall thickness.

For the first time AMG has combined the 6-litre V12 biturbo engine with the AMG SPEEDSHIFT PLUS 7G‑TRONIC. The seven-speed automatic transmission with its wide gear ratio spread enables a significantly lower engine speed and helps to reduce fuel consumption. A new fuel economy torque converter, bearings designed for reduced friction loss and the transmission-oil thermal management system are responsible for a further increase in the efficiency of the power transmission system.

The AMG SPEEDSHIFT PLUS 7G‑TRONIC has four different driving modes – Controlled Efficiency (C), Sport (S), Sport plus (S+) and Manual (M) – which can be selected at the push of a button on the centre console. In "C" mode the ECO start/stop function is permanently active. The compelling, dynamic character of the driving experience is made all the more vivid by the automatic double-declutching function during downshifts and through the brief, precisely defined interruption of ignition and fuel injection during upshifts under full load; the latter functionality has the additional benefit of reducing the shift times.
