Group T1

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.

Group T1 was first introduced in 1990 when the generic Group T, introduced the year before, was divided into four specific categories of cross-country vehicles. Until 2003 T1 was for series production cross-country cars, and prototype cars were placed in Group T3.^[2] However the modern arrangement, with T1 vehicles in Category II for competition vehicles, has been in place since 2004.^[3] These cars have been competing in Baja Cross Country Rallies, Rally Raids and Marathon Rallies since their inception, including in the FIA World Cup for Cross Country Rallies.
