The Audi R8 is no stranger to racing, having debuted in GT3 and endurance-racing competition back in 2009. The R8 LMS produces in excess of 500 horsepower from its V-10 engine, which sends power to the rear wheels only.
Based on the Audi R8 LMS racer, the R8 Grand-Am gets less downforce, a 10 millimeter higher ride height, a stouter roll cage (built from thicker tubing) and no ABS or traction control, which is allowed on LMS cars. Like the LMS, it’s also RWD only.
The V-10 engine is reduced to around 460 horsepower via an air restrictor and engine management software, but engine cooling is improved to cope with the stresses of U.S. endurance racing. Finally, the R8 Grand-Am gets a smaller, 22 gallon fuel cell.
Two R8 Grand-Ams will compete in this weekend’s race, include the car run by APR Motorsports (driven by Ian Bass, Jim Norman, Nelson Canache, Emanuele Pirro and Dion von Moltke) and the car campaigned by Onyx Racing (driven by Hurnaid Al Masaood, Steven Kane and Saeed Al Mehairi.
Onyx Racing is starting from the 15th position in the GT class, with APR starting from 22nd in class. Given that this is the car’s first time in competition, both are respectable efforts, and we wish both teams the best of luck this weekend.
