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 rally competition. The Group R regulations were gradually introduced from 2008 as a replacement for Group A and Group N rally cars.[1][2]
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.[3][4][5]

Toyota said the car will be able to compete in the World Rally Championship under the R1A regulations once it is homologated by the FIA before the end of the year.
