Who / What
Group B is a set of regulations introduced by the Fédération Internationale de l'Automobile (FIA) in 1982 for grand touring (GT) cars used in sports car racing and rallying. It specifically refers to an era when these regulations allowed significantly more powerful, lighter, and less restricted vehicles compared to Group C or other contemporary rules.
Background & History
The FIA created the Group B category alongside Group C for World Sportscar Championship events in 1982; however, it became predominantly associated with international rallying from that year until its end in the World Rally Championship (WRC) after the 1986 season. During this period, known as the golden era of rallying, manufacturers competed to build faster and more advanced homologation special vehicles within these regulations' constraints before they were superseded by stricter Group A rules.
Why Notable
Group B's notable significance lies in fostering some of the fastest, most powerful (exceeding 500 bhp), and technically sophisticated rally cars ever built. The era it represented is widely acclaimed as a peak period for motorsport innovation due to the limited regulations allowing engineers vast freedom, leading to immense public appeal and iconic performance despite its eventual cancellation due to safety concerns.
In the News
The legacy of Group B continues to be discussed in automotive media focusing on motorsport history, particularly the WRC era. Its recent relevance often involves comparing the high-performance homologation specials with today's regulations (like Super 2000) which offer less restriction while attempting to improve safety and control for rally competitors.
