We already saw some spy shots of it. Now, Audi revealed it at Essen Motor Show. It's a R8 race car, built for the GT3 race sires. The R8 GT3 Racer ditches the 4-wheel drive system for a standard rear wheel drive. And the 4.2L V8 now gets 500hp. The only transmission available is a 6-speed manual. Also, the R8 GT3 Racer gets GT3 sires body kits, such as a gigantic spoiler, racing wheel arches and a hood scoop.
So Aston Martin, Jaguar and Porsche should be worried now that Audi also joined the GT3 sires.
