Group Rally3 is a technical specification of rally car determined by the FIA. It features four-wheel drive and a maximum weight-to-power ratio of 5.6kg/hp. The class is used in the World Rally Championship (WRC) and regional championships. National rallying competitions also allow Group Rally3 cars to compete. There are three technical subclasses of Group Rally3 however these do not affect competitive eligibility so 'Rally3' may be used alone with the same definition. The group was launched in 2021 with the homologation of the first car after the introduction of the Rally Pyramid initiative to reorganise the classes of car and championships in international rallying was approved in June 2018.
