Why is "Group T3" trending?

Wikipedia Overview

In relation to motorsport, Group T3 is a set of technical specifications for lightweight prototype cross-country vehicles used in off-road Cross-Country Rallying. The group is governed by the Fédération Internationale de l'Automobile (FIA) and defined in appendix J, article 286 of its International Sporting Code. 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, 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. The vehicles must be powered by one engine and without driving aids such as traction control or ABS. Although not specifically defined as such by the FIA, the group may be called prototype side-by-side vehicles, like their series production relatives of Group T4. Indeed, T3 permits such modified and competition prepared vehicles where T4 prohibits them.
