Group T4

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.

The vehicles must be powered by one engine and without driving aids such as traction control or ABS.

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.

When competing in the FIA World Rally-Raid Championship there are no sporting classes within the group.
