Sports car racing is a form of circuit auto racing with automobiles that have two seats and enclosed wheels. They may be purpose-built or related to road-going sports cars.

A kind of hybrid between the purism of open-wheelers and the familiarity of touring car racing, this racing is often associated with the annual Le Mans 24 Hours endurance race. First run, it is one of the oldest motor races still in existence. Other classic but now defunct sports car races include the Targa Florio  and Mille Miglia. Most top class sports car races emphasise endurance reliability and strategy over pure speed. Longer races usually involve complex pit strategy and regular driver changes - sports car racing is seen more as a team sport than a gladiatorial individual sport and team managers like John Wyer, Tom Walkinshaw, driver-turned-constructor Henri Pescarolo, Peter Sauber and Reinhold Joest have become almost as famous as many of their drivers.

Championship for drivers and constructors of around 18 races a year featuring major international car and engine manufacturers, and independent constructors, such as Ferrari, McLaren, Williams, BMW Sauber, Toyota, Honda, Renault, Red Bull Racing - in an ongoing battle of technology and driver skill and talent.
