In relation to motorsport, Group T5 is a set of technical specifications for prototype cross-country trucks 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 287 of its International Sporting Code.[1]
The FIA launched prototype trucks as Group T4 in 1990, however the Groups T were restructured in 2020 when lightweight vehicles were introduced and the number of car groups were reduced. As part of this Group T4 trucks became Group T5.
