Group Rally1
Group Rally1 is a technical specification of rally car for use at the highest level of international rallying in the World Rally Championship (WRC) as determined by the FIA. Despite the use of the word 'Group' in the name, there are not multiple classes or subclasses of car and so 'Rally1' may be used alone with the same definition. Rally1 cars were used for the first time in the 2022 WRC season and replaced the outgoing World Rally Car used in the manufacturer's championship.
