Group B

In relation to motorsport governed by the FIA, Group A and Group B referred to two sets of regulations for competition vehicles in touring car and rally racing. Group B was introduced by the FIA in 1982 as replacement for both Group 4 (modified grand touring) and Group 5 (touring prototypes) cars.

Performance

The performance of the purpose-built Group B cars was incredible: Henri Toivonen drove a Delta S4 around the Portuguese Grand Prix track, Estoril, so quickly that he could have qualified just five places from the pole in the 1986 Grand Prix race. This same car could accelerate from 0 to 100 km/h on gravel in just 2.3 seconds.

The sheer and raw power of the Group B cars brought excitement and danger to rallying in the 1980's. But the ban of these cars was inevitable a few years later after such a heavy number of deaths and injuries especially the deaths of Henri Toivonen and Sergio Cresto.
