After tuning  and then building Mercedes-Benz performance cars for more than 40 years, for the first time in its history AMG is set to unveil an all-new model developed exclusively in-house.

The forthcoming Mercedes-Benz SLS AMG super sports car will revive the iconic ‘Gullwing’ namesake, boasting an aluminium spaceframe body and extensively tuned V8 front-mounted engine to deliver uncompromising performance.

The finely-tuned 6.3-litre, V8 engine in the SLS AMG achieves a peak output of 420kW at 6800rpm – compared to 336kW in the C63 AMG – and 650Nm at 4750rpm, making it one of the most powerful sports cars in its segment with a power-to-weight ratio of just 2.84kg/hp.

Initial performance tests have revealed the new ‘Gullwing’ accelerates from zero to 100km/h in 3.8 seconds, before going on to a top speed of 315km/h.

To reach these new heights in power, AMG employed an all-new intake system, reworked valve train and camshafts, the use of flow-optimised tubular steel headers and dethrottling of the exhaust system.

The switch to dry sump lubrication has also allowed engineers to lower the position of the engine in the vehicle, effectively lowering it’s centre of gravity for exhilarating driving dynamics.

The seven-speed dual-clutch transmission has been mounted at the rear to improve weight distribution, connected to the engine with an ultra-light carbon-fibre shaft – similar to the set-up used on the DTM C?Class racing touring car.

The driver has the choice of four driving modes ranging from comfort to sports, a three-stage ESP system as well as a RACESTART function for ultimate traction and safety together with exhilarating driving dynamics.

Keeping this power under control is an AMG high-performance composite brake package all-round with optional ceramic composite discs.

Development of the Mercedes-Benz SLS AMG began in the final quarter of 2006, due to be completed by the end of 2009 with the final production model available to customers in the first quarter of 2010.
