The Group S was the class which was to replace Groupe B in 1987. The FISA (Federation Automobile Internationnale de Sport) planned the Group S because she wanted a class making it possible to the manufacturers to develop futuristic cars. The rules required only ten copies, but the cars were limited to 300 horses. These rules are similar to the rules of the class WRC of today, which has a maximum of 300 horses and where 20 copies are necessary. The Group S never was likely to dispute the championship. After the death of Henri Toivonen, the FISA cancelled the projects for the Group S, and the manufacturers had cars under development which they could never use. Group A became the principal class for the manufacturers who remained after the death of the Group B One does not know anything more of the Group S because it was likely never to run in championship of the world of the rallys. This group would have been very interesting to look at because it aimed at making futuristic cars. Some of the prototypes under development appeared very interesting. That of Lancia resembled Lancia S4, with share which it was red and smaller. Audi had announced that it prepared a Group S, the Sport quattro RS 002. Ford also announced that the RS200 would be developed in Group S. current class WRC is probably what the Group S would have become. Thus, only one prototype
specimen was constructed for this Group S. This vehicle with short frame is equipped with a six-cylinder motor in central position postpones developing 300 CH. It was conceived in 1986. Its task was to succeed the Sport victorious quattro. With its withdrawal of the rallys and the annualtion of the creation of the Group S, Audi stopped its development. This single specimen remained a long time in the shade of the hangars of Ingolstadt until its exposure, in 1999-2000, with the Technical Museum of Sinsheim in Germany. It was then exposed in its state of origin (not completed).
