The history of the Audi Sport Quattro is intimately linked to the Group B rallying standards which were introduced by the Fédération Internationale de l'Automobile (FIA) in 1982. Group B rallying had no restrictions on the technology used, the weight of the vehicle or the boost capacity. Though Group B was disestablished later due to the accidents and deaths, its brief existence resulted in the creation of a powerful beast - the Audi S1 Quattro. Produced in 1985 and 1986 in limited numbers, this 2-door coupe was assembled in Ingolstadt, Germany. It was one of the most powerful cars of its times and was homologated into a road-going version to get the Audi Sport Quattro. The car stood at a height of 53 inches and was about 72 inches high. Its body extended to more than 160 inches in length and weighed about 1300 kilograms. The car sold for a heady price of $131,500.
