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 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 are not eligible to compete in either the WRC-2 or WRC-3 championships, but may instead compete for World Championship points alongside World Rally Cars.
