Mercedes-Benz SLS AMG GT3 road-race version

Hot on the heels of the SLS AMG, Mercedes-Benz has now revealed a GT3 race-ready variant of their flagship sports car. This racing version of the gullwing model was developed to comply with FIA GT3 specifications, and designed as a racing sports car for customers competing in sprints and long-distance races.

AMG, the performance brand within Mercedes-Benz, is “entering a new business sector with the new SLS AMG GT3,” with the development and sales of sports racing cars intended for customer use. Sales of these customer cars are expected to commence in autumn 2010, and homologation of the GT3 variant will be completed in time for the 2011 racing season.

The main focus when modifying the body of the Gullwing was on aerodynamic performance, as is seen not only in the new front apron with a splitter, the bonnet with its central cooling air vent and the wider front and rear wings, ane also in the the side wheel arch air vents, the sideskirts with cooling ducts for the rear brakes, the smooth underbody with a rear diffuser and the adjustable rear aerofoil. The C-pillars accommodate the standardised filler pipes for the fast-refuel system.

The FIA will determine the maximum output of the AMG 6.2-litre V8 front-mid engine with dry sump lubrication on the “Balance of Performance” principle. This is intended to ensure that all the racing cars taking part have an equal chance. The classification process, during which the weight is also determined, will be completed in 2010. Power transmission in the GT3 variant is by a sequential six-speed racing transmission with steering wheel shift paddles and an integrated multi-disc locking differential. Sharper steering, central-locking light-alloy wheels, racing bucket seats with harnesses, and a composite steel racing braking system with racing ABS round out the package.
