The 1987 Audi Sport quattro S1 E2 Pikes Peak represents the ultimate evolution of Audi's Group B rally technology and the final chapter in the marque's factory-backed domination of America's Mountain.
The 1986 Audi Sport quattro S1 E2 Pikes Peak occupies a unique place in Audi competition history. Driven by Bobby Unser to victory at the 1986 Pikes Peak International Hill Climb, it reclaimed the course record from Audi's own Michèle Mouton and delivered Unser's record-setting tenth overall victory on the mountain.
Following success at Pike's Peak with the quattro driven by John Buffum, Audi Sport brought its new Group B-homologated Sport quattro S1 to contest the 1984 Pike's Peak International Hillclimb with French rally driver Michèle Mouton.
