Audi R8 on the racetrack

How does a high performance super car like the Audi R8 do on a racetrack? Well that depends on whether you are looking for the tried and true 4.2 Liter FSI V8 making 420 HP or the new 525 HP V10 powered version. Either way, no matter which power plant you choose, one thing is certain. The R8 is a beautiful piece of automotive engineering.
