Audi's most potent coupe is the R8, whose mid-engine layout and extroverted styling puts the German brand in the running with some of the world's most desirable exotic cars. Bolstering the R8's status are numerous competition variants designed to compete in a variety of race series. Audi will sell you one of those, but be prepared to shell out serious coin. Most R8
models use Quattro AWD, but Audi has dabbled in RWD versions.
