In relation to motorsport, Group T4 is a set of technical specifications for modified production cross-country side-by-side vehicles 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 286a of its International Sporting Code.[1] The vehicles are modified for competition purposes from vehicles manufactured in numbers greater than 250 in a 12 month period. They must be road legal, but typically differ from the 'cars' defined in Group T1 and Group T2 by a much lower minimum weight (900 kg)and no requirement for parts such as a windscreen or windows. The vehicles must be powered by one engine and without driving aids such as traction control or ABS. Though the vehicles do not need to be homologated, a reference vehicle needs to be provided to the FIA for approval.[2]

History
Group T4 was first introduced in 1990 when the generic Group T, introduced the year before, was divided into four specific categories. At first, T4 was for cross-country trucks with no provision made for the modern "lightweight vehicle" until 2019 when two categories of Group T3 were established.[3] In 2020, T3-Prototypes became Group T3, and T3-Series became the Group T4 of today, with Trucks moved to Group T5. The side-by-side T4 vehicles have been competing in FIA Baja Cross Country Rallies, Rally Raids and Marathon Rallies since then, including in the FIA World Cup for Cross Country Rallies.
Classes
