The Audi quattro is not only successful in rally sport: Audi wins the prestigious hill climb up the legendary 4301 metre high Pikes Peak in the US State of Colorado three times in succession. Michèle Mouton triumphs in 1985, the American motorsport legend Bobby Unser wins in 1986 and Walter Röhrl in 1987. The powerful Audi Sport quattro S1, with almost 600 hp, storms up the peak in record time.
