Group B racing has been banned for about 20 years now. Seeing the recent Baja pics that Mjp posted got me to thinking about it. I was really young during it's heyday but I will never forget the sounds and sheer power of these cars. Not to mention the major pair of cahoney's these drivers had piloting these things.
In a nutshell: Group B = unlimited horsepower, technology, unlimited boost.
The Group B referred to a set of regulations introduced in 1982 for competition vehicles in sportscar racing and rally racing regulated by the FIA. The Group B regulations fostered some of the quickest, most powerful and sophisticated rally cars ever built. However, a series of major accidents, some fatal, were blamed on their outright speed. This led to the nickname "The killer B's". After the death of Henri Toivonen and his co-driver in the 1986 Tour de Corse, the FIA disestablished the class after only four years. The short-lived Group B era has acquired legendary status among rally fans.
It was banned in 1986..
