AUDI Quattro S1 Group B Walter Röhrl
Audi S1 TRIBUTE
Aufnahmen des Audi Sport quattro S1 (530 PS) und seinem Vorgänger dem Audi Sport quattro (450 PS). Der Audi Sport quattro S1 fuhr 1985 bei seiner ersten Rallye sofort den Sieg ein. Audi S1, ein Gruppe B - Monster...eines der wohl schönsten, spektakulärsten und besten Rallyeautos was es jemals gab. Zur Erinnerung an diese Legende und für alle Fans dieses Autos - mein Video. (Alles Aufnahmen von der Eifel Rallye - Slowly Sideways - der Jahre 2006 bis 2010)

Audi Quattro - Group B, the Days of Madness
Credits for this video: www.youtube.com/amjayes Group B was introduced by the FIA in 1982 as replacement for both Group 4 (modified grand touring) and Group 5 (touring prototypes) cars. Group A referred to production-derived vehicles limited in terms of power, weight, allowed technology and overall cost. The base model had to be mass produced (5000 units/year) and had to have 4 seats. Group A was aimed at ensuring a large number of privately-owned entries in races. By contrast, Group B had few restrictions on technology, design and the number of cars required for homologation to compete—200, less than other series. Weight was kept as low as possible, high-tech materials were permitted, and there were no restrictions on Boost, which turned out to mean almost unlimited power. The category was aimed at car manufacturers by promising outright competition victories and the subsequent publicity opportunities without the need for an existing production model. There was also a Group C, which had a similarly lax approach to chassis and engine development, but with strict rules on overall weight and maximum fuel load. Group B was initially a very successful concept, with many manufacturers joining the premier World Rally Championship, and increased spectator numbers. But the cost of competing quickly rose, and the performance of the cars proved too much, resulting in a series of fatal crashes. As a consequence Group B was cancelled at the end of 1986 and Group A regulations became the standard for all cars until the advent of World Rally Cars in 1997. In the following years Group B found a niche in the European Rallycross Championship, with cars such as the MG Metro 6R4 and the Ford RS200 competing as late as 1992. For 1993, the FIA replaced the Group B models with prototypes that had to be based on existing Group A cars, but still followed the spirit of Group B, with low weight, 4WD, high turbo Boost pressure and staggering amounts of power.
