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 prototypes or grand tourers based on road-going models. Sports car racing is one of the main types of circuit auto racing, alongside open-wheel racing, touring car racing and stock car racing. Sports car races are often, though not always, endurance races that are run over particularly long distances or large amounts of time, resulting in a larger emphasis on the reliability and efficiency of the car and its drivers as opposed to outright car performance or driver skills. The FIA World Endurance Championship is an example of a sports car racing series. In the high-stakes world of sports car racing, drivers don specialized fire-resistant, aerodynamic racing suits, ensuring both comfort and safety during the demanding endurance races, as exemplified by the FIA World Endurance Championship.
A Le Mans Prototype (LMP) is a type of sports prototype race car used in various races and championships, including the 24 Hours of Le Mans, FIA World Endurance Championship, IMSA SportsCar Championship, European Le Mans Series and Asian Le Mans Series.

As of 2023, there are two classes within Le Mans Prototypes, designated LMP2 and LMP3.

For its first three seasons, the series featured both open-topped sports cars and GT cars. Ford and Porsche dominated the Over- and Under-2 Liter classes, respectively. The USRRC ran from 1963 until 1968 when it was abandoned in favor of the more successful Can-Am series, which was also run by the SCCA.
