Homologation (motorsport) in the context of Fédération Internationale de Motocyclisme

A sports car is a type of automobile that is designed with an emphasis on dynamic performance, such as handling, acceleration, top speed, the thrill of driving, and racing capability. Sports cars originated in Europe in the early 1910s and are currently produced by many manufacturers around the world.

A sports prototype, sometimes referred to simply as a prototype, is a type of race car that is used in high-level categories of sports car racing. They are purpose-built auto-sports race cars, as opposed to production-car based or street-legal, low-volume homologation specials – thus entirely not intended for consumer purchase, or production beyond the fabrication of the (nearly) unique cars entered into races and in race-car competition classes or "formulas", with sufficiently open regulations to allow for vehicles of unique design to partake.

Prototype racing cars have competed in sports car racing since before World War II, but became the top echelon of sports cars in the 1960s as they began to replace homologated sports cars. Current ACO regulations allow most sports car series to use two forms of cars: grand tourers (GT cars), which are strictly based on production street cars, and sports prototypes, which are allowed a great amount of flexibility within set rule parameters.

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".

Just 36 of the 250 GTOs were manufactured between 1962 and 1964. This includes 33 cars with 1962–63 bodywork (Series I) and three with 1964 (Series II) bodywork similar to the Ferrari 250 LM. Four of the older 1962–1963 (Series I) cars were updated in 1964 with Series II bodies.
