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.
R5 cars are eligible to compete in the World Rally Championship-2 and the championship's professional class for manufacturer teams. From 2020, the professional class will become the World Rally Championship-2 and privateer entries will contest the World Rally Championship-3.
