The traction advantage of Audi quattro® is as apparent today as it was then. The first time quattro® made an appearance at a timed event, it completed the course 30 minutes ahead of the next fastest car. That would have been quite a victory, were it competing. It was there simply to test the system and to warn onlookers that racecars would be following.
When Audi introduced quattro® at the World Rally Championship, the result was an astounding 24 wins over the next 4 years. quattro® dominated the WRC, Pikes Peak hill climb, IMSA-GTO and TransAm series until it was later deemed an unfair advantage and banned from road racing altogether.
