As for the engine, the 4.2L V8 has supposedly been tweaked to produce 500 horsepower (up from 420). For all its wings, vents and fender flares, this R8 GT3 prototype reportedly only managed to lap the 'Ring in 8:41.00 due to slippery-when-wet conditions. Pay attention folks, as this is the turn-key racing R8 that Audi will soon unleash on teams who wish to crash the GT3 class in style.© Source: autoblog
