Audi is bidding adieu to the R8 with a GT RWD limited to 333 coupes. If that special edition isn't wild enough, ABT Sportsline has developed a truly bonkers version of the supercar. Meet the XGT, essentially a race car for the road since it takes the shape of a street-legal R8 GT2. It effectively extends the life cycle of the naturally aspirated machine since Audi is supplying 99 rolling chassis to the German company.
