Audi Quattro S1

"One of the most significant rally cars of all time made its introduction in 1980, with the unveiling of Audi?s Quattro. The Quattro was the first rally car to take advantage of the new rules permitting four-wheel-drive for rally. There were some initial doubts about four-wheel-drive?s suitability for rallying, some thought it would be far too complex and heavy to be competitive. This was quickly proven wrong. The Quattro won its first rally on its first outing, the Austrian round of the European championship in 1981: the four-wheel-drive experiment was an instant success. The Quattro went on to win a several rounds of the world rally championship, and Audi gained additional exposure when Michèle Mouton won the 1981 San Remo rally, the first woman to win at the international level."
