Group B

Group B was a set of regulations introduced in 1982 for competition vehicles in sportscar racing and rallying regulated by the FIA. The Group B regulations fostered some of the quickest, most powerful and sophisticated rally cars ever built and is commonly referred to as the golden era of rallying. However, a series of major accidents, some of them fatal, were blamed on their outright speed and lack of crowd control. After the death of Henri Toivonen and his co-driver Sergio Cresto in the 1986 Tour de Corse, the FIA disestablished the class, which was replaced as the top-line formula by Group A. The short-lived Group B era has acquired legendary status among rally fans.
