Group B Rallying was the maddest and craziest the World Rally Championships had ever been. The Group B rallying lasted from around 1982 to 1986 where drivers got killed and spectators too. The cars were ridiculously overpowered. In those days, Group B cars had little restrictions on technology, design and the even the number of homologated cars that would have to be sold to the public was less (about 200 cars or so, usually manufacturers ended up making less but got away with it). Very low weight was allowed with high-tech materials permitted, and there were no restrictions on boost (unlike the group A cars that actually form the basis of WRC rallying to this day). This usually resulted in the power output of Group B specials hitting 500bhp in 1986, the final year of Group B. Every big manufacturer wanted in on it as it was interesting. Performance and power without limits.
