Group Rally3 is a technical specification of rally car determined by the FIA. It features four-wheel drive and a maximum power-to-weight 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.[1]

The group was designed to be entry level and the cheapest way to go rallying with four-wheel drive, as existing options like Group Rally2 and Group Rally2-Kit were considered too expensive for some privateers, and too high performance for newcomers to 4WD cars.

Two-wheel-drive R3 cars from Group R were at level RC3 with the mentioned Rally2 and Rally2-Kit at level RC2 in the FIA's sporting classes. With the introduction of Rally3, R3 were reclassified to RC4.[1]

Definition

Group Rally3 cars are defined in FIA document 'Appendix J - Article 260' as Touring Cars or Large Scale Series Production Cars, petrol engine, 4-wheel drive. A production touring car with at least 2500 identical units manufactured must be homologated in Group A, with all the components and changes that make it a Group Rally3 car homologated in an extension.[2]

Cars have a 31mm air intake restrictor, a maximum power-to-weight ratio of 5.6kg/hp, and a rally-ready price cap of €100,000 plus taxes.[3][1]

The subclasses are based on engine cylinder capacity in common with existing Group Rally4 classes, allowing for possibility of upgrade or sharing of many components with a Rally4 car.
