Group B rallying was a category of rally racing that took place from 1982 to 1986. It featured highly modified, powerful cars that were designed for extreme performance on various terrains. The regulations allowed manufacturers to create vehicles with fewer restrictions, leading to innovations in technology and design. Popular models included the Audi Quattro, Lancia Delta S4, and Peugeot 205 T16. The excitement of Group B rallying was matched by its dangers, as the high speeds and challenging courses often resulted in serious accidents. The tragic incidents during events led to the category being banned in 1986, marking the end of an era in motorsport history.
