Sports car racing is a form of motorsport road racing which utilises sports cars that have two seats and enclosed wheels. They may be purpose-built (Prototype) or related to road-going models. Broadly speaking, sports car racing is one of the main types of circuit auto racing, alongside open-wheel single-seater racing, touring car racing and stock car racing. Sports car races are often endurance races that are run over relatively large distances, and there is usually a larger emphasis placed on the reliability and efficiency of the car than in some of the other types of auto racing. The FIA World Endurance Championship is an example of a sports car racing series.
