Mercedes has officially revealed the new SLS AMG GT3 race car, powered by the street car’s 6.2-liter AMG V8 engine. No official power numbers are available but Mercedes says the engine is almost identical to the 563-hp unit in the street car. Thanks to a special six-speed sequential racing transmission and ultra-low curb weight, the GT3 can rocket to 60 mph in just 3.7 seconds.

That light-weight body is made entirely of carbon fiber, with impressive new aerodynamics including a massive front splitter, rear diffuser and enormous rear spoiler. Compared to the road car, the GT3′s bodywork is two inches wider, enough to accommodate some massive center locking 18×12-inch front and 18×13-inch rear wheels with racing slicks. Inside those wheels is a special composite AMG race braking system with six-piston front calipers and four-piston rear calipers.

Mercedes has announced the FIA GT3 spec car is able to compete in all FIA GT3 series, including the 24-hour races at Spa-Francorchamps, Belgium, and on the Nürburgring in Germany. There’s no word on a factory backed team and initially Mercedes will offer the car for sale to customers this Fall, with delivery set for just ahead of next year’s racing season.
