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.[1]
The formula for Group Rally5 cars was taken from R1 class of Group R with the defining ruleset interchanging the terms, this meant that any existing R1 car homologated or approved since their introduction in 2008 could continue to be used in Rally5 level competition.[2] The subclasses defined in R1 however have effectively merged and capacity of permitted turbocharged engines have increased to 1333cc.[2]
