In international rallying, R5 refers to a class of cars competing under Group R regulations. R5 regulations were introduced by the Fédération Internationale de l'Automobile (FIA) in 2012 as a replacement for the Super 2000 class. In 2019 the FIA renamed the R5 specification ruleset to Group Rally2 as part of a wider plan to reorganise FIA championships and replace Group R with new Groups Rally.[1][2][3] Existing FIA homologated R5 cars remain eligible for any FIA Rally2 level competition, and non-homologated R5 or Rally2 cars should be accepted equally at national level where approved. R5/Rally2 cars are based on production cars and feature a 1600cc turbocharged petrol engine.
^The 2019 season saw the running of two categories known as the World Rally Championship-2 Pro for manufacturer teams, and the World Rally Championship-2 for privateers. However, this multi-class structure was found to be too confusing, and so the category was re-structured for the 2020 season.[4]
