the r8 is the r10 road car, wich you mean...........

wait... the R10 has nothing to do with that Audi A4.... they disasebled the A4, including the engine... then built a race car around their preformance engine......... all in all Audi is still great, but those 2 cars had nothing to do with each other.... they should make a R10 Road Car :-) that would own
