In 1982, the Fédération Internationale du Sport Automobile (FISA) restructured the production car category of [[Appendix J|Appendix J of the International Sporting Code]] to consist of three new groups.

The outgoing [[Group 1 (motorsport)|Group 1]] and [[Group 2 (motorsport)|Group 2]] were replaced with [[Group N]] and [[Group A]], for unmodified and modified production [[Touring car racing|touring cars]] respectively. These cars had to have four seats (although the minimum size of the rear seats was small enough that some [[2+2 (car body style)|2+2]] cars could qualify) and be produced in large numbers. Their [[Homologation (motorsport)|homologation]] requirement was 5000 units in a 12-month period between 1982 and 1992. From 1993, the requirement was reduced to 2500 units.<ref name="J1992">{{cite web |title=Appendix J 1992 |url=https://historicdb.fia.com/sites/default/files/regulations/1440578063/appendix_j_1992.pdf}}</ref><ref name="J1993">{{cite web |title=Appendix J 1993 |url=https://historicdb.fia.com/sites/default/files/regulations/1440578161/appendix_j_1993_low.pdf}}</ref>

Group B was for GT cars with a minimum of two seats, redefined as sports grand touring cars in 1986. It combined and replaced [[Group 3 (motorsport)|Group 3]] and [[Group 4 (motorsport)|Group 4]], two grand touring groups already used in rallying, and the production-derived [[Group 5 (motorsport)|Group 5]] [[Silhouette racing car|silhouette cars]] used in circuit racing.<ref name=":1">{{Cite web |title=The anatomy of a Group B rally car – history and tech of rallying's golden era |url=https://www.evo.co.uk/rallying/20384/the-anatomy-of-a-group-b-rally-car-history-and-tech-of-rallyings-golden-era |access-date=2022-05-24 |website=evo |language=en}}</ref> Group 5 cars had never been permitted in the World Rally Championship for Manufacturers.
