In relation to motorsport governed by the Fédération Internationale de l'Automobile, Group R refers to a set of regulations providing production-derived vehicles for outright competition. The Group R regulations were created in 2012 as a replacement for Group A and Group N cars, and took effect from 2013. No new cars will be homologated under Group A or Group N regulations, and instead existing cars are reclassified according to Group R rules. As part of its structure, the Group R regulations have a provision for GT cars, known as RGT.
Classes under Group R
Group R consists of six classes, designated R1, R2, R3, R4, R5, R6 and RGT; some of these groups will contain their own sub-groups, with cars allocated to each group based on their weight, engine size and powertrain. Teams and drivers are sorted into a specific championship based on the class their car fits into. Cars classified as R1, R2 and R3 contest the World Rally Championship-3 for two-wheel drive cars; specially-prepared R3T cars are also used in the Junior World Rally Championship. Cars classified as R4 and R5 compete in the World Rally Championship-2 alongside existing Super 2000 and Group N Production Cars. Cars classified as RGT compete in the R-GT Cup.

- ^1 — The R4 class is for cars competing under Group N regulations for production cars prior to 2013. No new cars will be homologated under Group N regulations, and the R4 category will be gradually phased out.
- ^2 — Until 2014 there was no specific championship for cars entered under RGT regulations, and RGT cars were ineligible to score points in any existing championship outside the World Rally Championship. The FIA R-GT Cup for RGT cars will start from 2015 sharing some events from the WRC and ERC events.
