==Homologation==
To qualify for FIA approval, 2,500 identical models have to be built in 12 consecutive months.<ref name="J255" /> 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.<ref name="J251" /> Evolutions of the series production model homologated are permitted with a ET (Evolution of the type) extension applied.<ref name="J251" /> Before 1993 the initial production requirement was 5000.<ref>{{cite web|title=FIA Yearbook of Automotive Sport 1982|url=https://historicdb.fia.com/sites/default/files/regulations/1439540890/appendix_j_1982.pdf}}</ref>

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. One such example of this was Volvo with the 240 Turbo in 1985, an evolution of a model first homologated in 1982. 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 [[Fédération Internationale du Sport Automobile|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.<ref>{{Cite web|url=http://flathood.saliv8.com/history.php|title = 1983 Volvo 242 Group-A Turbo}}</ref>

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 [[Holden VN Commodore|VN Commodore SS Group A SV]] in 1991 (though they had no problems producing 5,000 base model [[Holden VN Commodore|VN Commodore]]s). 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 [[Holden VL Commodore SS Group A SV|VL Commodore SS Group A SV]] which had been designed by [[Tom Walkinshaw Racing|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.
