Many of the redundant Skylines found a new home in the form of the JGTC (Japanese GT Championship) with modified aerodynamic devices, showing its competitiveness whilst being up against Group C, former race modified roadcars and specially developed racers, like the Toyota Supras during the earlier years. The German Deutsche Tourenwagen Meisterschaft (DTM) switched to a 2.5L Class 1 formula in 1993, while in Japan in 1994 the Japanese Touring Car Championship organisers followed suit and switched classes like most other countries who had adopted the British Touring Car Championship-derived Supertouring regulations. The FIA continued to promulgate regulations for Group A touring cars until at least 1993, however Group A survived in touring car racing in domestic championships until 1993. Tyre width was dependent on the car's engine size. These cars competed in standard bodykits, with the production-derived nature required manufactures to release faster vehicles for the roads in order to be competitive on the track. In the European Touring Car Championship, Group A consisted of three divisions, Division 3 – for cars over 2500cc, Division 2 – for car engine sizes of 1600–2500cc, Division 1 for cars that are less than 1600cc.

As a result, after FISA's failed attempt at finding an "Evolution" car in any European countries, Volvo were forced to reveal the names of all 500 "evo" owners to be permitted to compete. ![]() After they had produced 500 such models, Volvo stripped 477 cars of their competition equipment and sold them as standard 240 turbo roadcars. One such example of this was Volvo with the 240 Turbo in 1985, an evolution of a model first homologated in 1982. However, not all manufacturers who built such models sold them all, some stripped the majority of them to rebuild them as stock models or used them to allow teams to use modified parts. Before 1993 the initial production requirement was 5000. Evolutions of the series production model homologated are permitted with a ET (Evolution of the type) extension applied. The homologation period lasts for every subsequent year of production and seven years after the year that less than 10% (250) are produced in one year and the model is considered out of production by the FIA. To qualify for FIA approval, a minimum of 2,500 identical models have to be built in 12 consecutive months. Both Groups N and A, and the details of their differences are described in the FIAs International Sporting Code and several of its Appendices J articles. In recent years Groups A and N have begun to be phased out in eligibility in championships though they continue to form the homologation basis for most production based race car formulae including the Groups Rally which must first be homologated in Group A. Cars from multiple Groups could contest the World Rally Championship for Manufacturers for example until 1997 when the specific World Rally Car formula was introduced as the only option. ![]() During the early years there were no further formula for production based race cars. ![]() Group A was introduced by the FIA in 1982 to replace the outgoing Group 2 as "modified touring cars", while Group N would replace Group 1 as "standard touring cars". Group A was aimed at ensuring numerous entries in races of privately owned vehicles. In contrast to the short-lived Group B and Group C, Group A vehicles were limited in terms of power, weight, allowed technology and overall cost. Group A is a set of motorsport regulations administered by the FIA covering production derived touring cars for competition, usually in touring car racing and rallying. ![]() Lancia Delta HF integrale Group A Mitsubishi Lancer Evolution VI, Tommi Mäkinen edition, a Group A rally car For other uses, see Group A (disambiguation).
