Homologation (motorsport)
In motorsport, homologation is a testing and certification process for vehicles, circuits, and related equipment for conformance to technical standards, usually known as type approval in English-language jurisdictions. It confirms conformity to standards or categorisation criteria typically set by the sporting authority. At international and supra-national level, the FIA and FIM mandate what must be homologated, the FIA in its International Sporting Code and appendices. National sporting authorities such as Motorsport UK must adhere to these rules but may enforce additional or specific homologation rules applicable to their series or jurisdiction, however, unaffiliated series may set their own requirements.

The Ferrari 250 GTO is a grand tourer produced by Ferrari from 1962 to 1964 for homologation into the FIA's Group 3 Grand Touring Car category. It was powered by Ferrari's Tipo 168/62 Colombo V12 engine. The "250" in its name denotes the displacement in cubic centimeters of each of its cylinders; "GTO" stands for Gran Turismo Omologato, Italian for "Grand Touring Homologated".
