In relation to motorsport governed by the FIA, Group A referred to a set of regulations providing production-derived vehicles for outright competition. In contrast to the short-lived Group B and Group C, the Group A referred to production-derived vehicles limited in terms of power, weight, allowed technology and overall cost. Group A was aimed at ensuring a large number of privately owned entries in races. 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 officially discontinued at the end of 1988, but it survived in touring car racing in domestic championships until 1994. However, Group A is still used as the basis for most rally competitions around the world. ==Homologation== To qualify for approval, a minimum of 2500 cars of the competing model had to be built in one year, out of 25,000 for the entire range of the model (e.g.: 2500 Subaru Impreza WRX, out of 25,000 Subaru Impreza). Up to 1991, the requirement was a minimum of 5000 cars in one year, without regard to the entire range, but the FIA allowed "Evolution" models to be homologated with a minimum of 500 cars (e.g.: BMW M3 Sport Evo, Mercedes-Benz W201 Evo, Nissan Skyline GT-R NISMO). Rules also required some of the interior panels to be retained, e.g. interior door panels and dashboard. However, not all manufacturers who built 500 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. One such example of this was Volvo with the 240 Turbo in 1985. After they had produced 500 such models, Volvo stripped 477 cars of their competition equipment and sold them as standard 240 turbo roadcars. 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. The other example was Ford, after selling off their entire RS500 stocks, they read the rulebooks and found themselves that rather than using either the Sierra Cosworths or the RS500s, they could use the body of the basic 3-door Sierra, which Ford was discontinuing, and use their Evolution equipment on them. Nowadays, these cars are treated as any other model in the range. Australian manufacturer Holden also failed to build the required 500 cars for their VN Commodore SS Group A SV in 1991 (though they had no problems producing 5,000 base model VN Commodores). There were in fact only 302 of the Group A SV's built. However, since Group A as a category was to be replaced from 1993 in Australia, and to give Holden's latest flagship model a presence in Australian touring car racing (the previous model VL Commodore SS Group A SV which had been designed by TWR had been racing since 1988, though it was actually released after Holden had already launched the VN model), the Confederation of Australian Motor Sport (CAMS) fully homologated the VN Commodore for racing. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Group A」の詳細全文を読む スポンサード リンク
