German tuner PPI Automotive dropped cloth on their PPI Razor GTR at the 2009 Top Marques show in Monaco. The razor-sharp 580 HP tuned Audi R8 sports numbers that beat the R8 5.2 V10.

Audi just took the wraps off the 517 HP R8 V10. The Audi R8 5.2 FSI can do 0-60 in 3.9 seconds, hit nearly 200 MPH and looks damn good in red.
