Group Rally5 is a technical specification of rally car determined by the FIA for use in its international rallying competitions: World Rally Championship (WRC) and regional championships. National rallying competitions also allow Group Rally5 cars to compete. There are no subclasses of the group therefore all Group Rally5 cars can compete in the same category. 'Rally5' may be used alone with the same definition. The group was launched in 2019 after the introduction of the Rally Pyramid initiative to reorganise the classes of car and championships in international rallying was approved in June 2018.
