and Group N rally cars. To comply with Group R regulations, a car must first be homologated in Group A (or in some cases Group N) and receive one or more VR extensions. Each VR extension is a set of homologated parts and modifications, designed and sold (as a kit or as a complete car) by the manufacturer. As part of its structure, the Group R regulations have a provision for GT cars, known as R-GT.


Classes

Group R consists of six classes, designated R1, R2, R3, R4, R5 and R-GT; some of these groups contain their own sub-groups, with cars allocated to each group based on their weight, engine size and powertrain. The first batch of rules, which were introduced in 2008, featured the R1, R2 and R3 classes. These were restricted to two-wheel drive cars with atmospheric engines up to 2000cc. Supercharged engines were allowed only in R3T (petrol) and R3D (diesel) sub-classes. Since 2015 the R1, R2 and R3 classes allow supercharged engines with a 1.5 equivalency factor for displacement. Additional regulations were issued in 2011 which covered the R4 and R-GT classes; the R4 was conceived as an evolutionary step for previously-homologated Group N4 cars, turbocharged, all-wheel drive cars based on production models. The R4 class is for cars competing under Group N regulations for production cars prior to

. No new models would be homologated under R4 regulations, with the FIA taking the long-term view that these would be replaced by bespoke kit cars. The R4 Kit cars have a standard engine, four-wheel drive powertrain and suspension. In January 2017, French racecar manufacturer Oreca was selected as supplier. R-GT was introduced to allow Grand Touring cars that competed in
