Group Rally2 is a technical specification of rally car determined by the FIA.

It features 1.6L turbo engines, four-wheel drive and a maximum power-to-weight ratio of 4.2kg/hp.

The group was launched in 2019 with other similarly named groups 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 Rally2 cars was taken from R5 class of Group R with the defining ruleset being renamed, this meant that any existing R5 car homologated or approved since their introduction in 2013 could continue to be used in Rally2 level competition.

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 Rally2 car homologated in an extension.
