Automotive fascination combined with spectacular racing car design – the new Mercedes-Benz SLS AMG GT3. This racing version of the gullwing model was designed as a customer sports car for competing in race series according to the near-series FIA GT3 rulebook. Outstanding driving dynamics are ensured by uncompromising lightweight construction and specific modifications to the suspension, brakes and aerodynamics.
Near-series AMG 6.3-litre V8 engine
As prescribed by the FIA GT3 rules, the AMG 6.3-litre V8 engine is practically identical to that in the standard model. Thanks to its lower weight, the GT3 will considerably better the already outstanding acceleration of the standard model – 3.8 seconds from zero to 100 km/h; depending on the final drive ratio, the top speed will exceed 300 km/h. Typical of an AMG: the thrilling and characteristic eight-cylinder sound.
The peak output of the AMG 6.3-litre V8 front-mid-engine with dry-sump lubrication is determined by the FIA according to the "Balance of Performance". This is to ensure equal chances for all the participating racing cars. Classification, which also determines the kerb weight of the vehicle and other factors, will take place in spring 2011.
The AMG 6.3-litre V8 engine also has a dry sump lubrication system in the racing model. Using vacuum and pressure pumps, as well as an external oil tank, makes it possible to dispense with a conventional sump. This technology ensures reliable engine lubrication even under the high lateral acceleration forces encountered on the racetrack. Dry sump lubrication also allows a low installed position for the V8 engine – one of the key technological highlights of the SLS AMG. Installing the eight-cylinder as low as possible, as a front-mid-engine behind the front axle, and combining it with a transmission located at the rear axle, leads to a favourable weight distribution. The transaxle arrangement also optimises handling and traction.
