In relation to motorsport, Group T1 is a set of technical specifications for prototype cross-country cars used in off-road Cross-Country Rallying (also called Rally Raid). The group is governed by the Fédération Internationale de l'Automobile (FIA) and defined in appendix J, article 285 of its International Sporting Code.[1] The cars are single unit builds and may be based on a spaceframe chassis unlike the strict series production bodyshell requirement in Group T2. However, the engine must come from, or be derived from a production car able to be homologated in Group A, Group GT or Group T2. The cars must be powered by one engine and without driving aids such as traction control or ABS.
