In relation to motorsport,Group T1 is a set of technical specifications for prototype cross-country cars used inoff-roadCross-Country Rallying (also called Rally Raid). The group is governed by theFédération Internationale de l'Automobile (FIA) and defined in appendix J, article 285 of itsInternational Sporting Code.[1] The cars are single unit builds and may be based on a spaceframe chassis unlike the strict series production bodyshell requirement inGroup T2. However, the engine must come from, or be derived from a production car able to be homologated inGroup A,Group GT or Group T2. The cars must be powered by one engine and without driving aids such astraction control orABS.
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 theFIA World Cup for Cross Country Rallies.
When competing in theFIA World Rally-Raid Championship, which includes the long establishedDakar Rally, there are four classes within the group:[4]
