Fast and sexy get faster oh so sexier!
The Mercedes-Benz SLS AMG will surely be one of the most talked-about cars of 2010. Just in case that was not going to happen, Mercedes has just revealed the GT3 edition. Uh, booooyaah! Believe it or not, this car is intended for customer use. Sales will commence in autumn 2010, and homologation of the GT3 variant will be done in time for the 2011 racing season. For the moment, the FIA has not determined the maximum output of the AMG 6.3-litre V8 because of the "Balance of Performance" principle. Let's bet it'll still be a lot...

As reported by Mercedes-Benz
Montvale NJ
- Automobile fascination paired with spectacular race car design - that is the new Mercedes-Benz SLS AMG GT3. The racing version of the SLS AMG has been conceived as a customer sport vehicle for participation in race series based on FIA GT3 regulations. Meticulous lightweight construction and optimized chassis, brakes and aerodynamics deliver uncompromising dynamics. The extra special SLS AMG will make its race track debut in 2011.

The clean design and breathtaking form of the SLS AMG have been effectively accentuated by targeted modifications to the bodyshell. The new components, made largely from lightweight carbon fiber offer a clear indication of extraordinary race track performance and extensive aerodynamic development work.

From the front, the GT3 race car boasts a new front skirt with enlarged air intakes. The wide opening beneath the characteristic radiator grille bearing the large Mercedes star and the wing-shaped horizontal fins supplies air to the engine oil cooler and brake discs. The same function is served by the two intakes below the vertical bi-xenon headlamps. Downforce on the front axle is provided courtesy of four externally mounted side flics, as well as a carbon front splitter; it runs directly into the smooth underbody panel, which connects to the rear diffuser.

The hood features a central opening for the extraction of heat from the engine, while side openings in the front fenders facilitate air flow through the wheel arches. Weight optimization measures include the application of extremely lightweight polycarbonate for the side and rear windows and, if desired, for the front windshield as well.

The fenders have been widened front and rear to accommodate the large racing tires. With a breadth of 78.3 inches, the GT3 bodyshell is a good 2 inches wider than the series production SLS AMG. The new sills feature openings for cooling the rear brakes, with the smooth underbody visible along the underside of the sills. The B-pillar houses the standardized fuel tank adapter for the rapid refueling system. The 31.7 gallon fuel tank is located centrally behind the driver.

Wide rear carbon spoiler
The rear view of the SLS AMG GT3 is dominated by its imposing width. Above the rear hatch sits a wide carbon fiber spoiler; it is extensively adjustable and facilitates perfect setup to suit individual race track characteristics. The new rear skirt accommodates two openings for extracting air from the rear wheel arches. A further visual highlight is the rear carbon fiber diffuser; it rises smoothly from the rear axle area as a continuation of the smooth underbody, its form adding to the downforce. The overall aerodynamic concept of the SLS AMG GT3 was analyzed and defined through extensive wind tunnel and race track testing.
