Group T3

The group is governed by the Fédération Internationale de l'Automobile (FIA) and defined in appendix J, article 286 of its International Sporting Code.

[1] The vehicles are generally single unit builds for competition purposes, and differ from 'cars' defined in Group T1 by not needing to be road-legal (except for lighting), and have a much lower minimum weight.

The T3 vehicles also do not need parts such as a windscreen or an engine manufactured by series production car companies.

Until 2002, T3 was for prototype cross-country competition cars, with no provision made by the FIA for the modern "lightweight vehicle".

When competing in the FIA World Rally-Raid Championship, which includes the long established Dakar Rally, there are no sporting classes within the group.
