Group Rally2 (previously known as R5) is a technical specification of rally car determined by the FIA. It features 1.6L turbo engines, four-wheel drive and a maximum weight-to-power ratio of 4.2 kg/hp. Rally2 cars are used in the World Rally Championship, exclusively in its WRC2 support championship; the FIA continental championships and in national championships. The technical regulations were developed ahead of the 2012 rallying season and known as R5 within the scope of Group R. In 2019, with the reorganisation of the Rally Pyramid, the ruleset was renamed as Group Rally2. This meant that any existing R5 car homologated or approved since their introduction continue to be used in Rally2 level competition. R5 cars were first introduced as an intended replacement for the S2000 car. There are no subclasses despite the use of the word 'Group' in the name, so 'Rally2' may be used alone with the same definition. In years prior to 2019, 'Rally 2' was used to describe the rules and scenario allowing a rally competitor to restart a rally the day following a retirement. This was renamed 're-start after retirement' in FIA regulations from 2019. Rally2 should not be confused with R2 cars of Group R either, which are officially described as 'Rallye 2'.
