Sports car racing
The Audi R8 was one of the most successful sports prototypes ever made, seen here at Road Atlanta.

In sports car racing, production derived versions of sports cars also known as grand tourers (GTs), and purpose built sports prototype cars compete within their respective classes on closed circuits. The main global championship series for GT car racing is the FIA GT1 World Championship. There is also the FIA GT2 European Championship and the FIA GT3 European Championship as well as the less powerful GT4 European championship. Other major GT championships include the Japanese Super GT championship and the International GT open for GT2 and GT3 cars. There are also national GT championships using mainly GT3 and GT4 cars featuring professional and amateur drivers alike.

Sports prototypes, unlike GT cars, do not rely on road legal cars as a base. They are closed wheel and often closed cockpit purpose built race cars intended mainly for endurance racing. They have much lower weight and more down force compared to GT cars making them much faster. They are raced in the 24 hours of Le Mans and in the (European) Le Mans series, Asian Le Mans series and the American Le Mans series ALMS. These cars are referred to as LMP (Le Mans prototype) cars with LMP1 being run mainly by manufacturers and the slightly less powerful LMP2 cars run by privateer teams.

These races are often conducted over long distances, at least 1,000 km (621 mi), and cars are driven by teams of two or more drivers, switching every few hours. Due to the performance difference between production-based sports cars and purpose-built sports prototypes, one race usually involves several racing classes each fighting for their own championship. Another prototype and GT racing championship exists in the United States, which began in 2000, the Grand-Am, sanctions its own endurance series the Rolex Sports Car Series which consists of slower and lower cost race cars compared to LMP and FIA GT cars.

Famous sports car races include the 24 Hours of Le Mans, the 24 Hours of Daytona, 24 Hours of Spa-Franchorchamps, the 12 Hours of Sebring, and the 1,000-mile (1,600 km) Petit Le Mans at Road Atlanta. There is also the 24 Hours of the Nürburgring on the infamous Nordschleife track and the Dubai 24 Hour which is aimed at GT3 and below cars with a mixture of professional and pro-am drivers.

RALLYING

Rallying at international and most national championship levels involves two classes of homologated road legal production based car; Group N Production cars and more modified Group A cars. Cars compete on (closed) public roads or off-road areas run on a point-to-point format where participants and their co-drivers "rally" to a set of points, leaving in regular intervals from start points. A rally is typically conducted over a number of "special stages" of any terrain, which entrants are often allowed to scout beforehand at reduced speeds compiling detailed shorthand descriptions of the track or road as they go. These detailed descriptions are known as "pace notes." During the actual rally, the co-driver reads the pace notes aloud (using an in-helmet intercom system) to the driver, enabling them to complete each stage as quickly as possible. Competition is based on lowest total elapsed time over the course of an event's special stages, including penalties.

The top series is the World Rally Championship (WRC), but there also regional championships and many countries have their own national championships. Some famous rallies include the Monte Carlo Rally, Rally Argentina, Rally Finland and Rally GB. Another famous event (actually best described as a "rally raid") is the Paris-Dakar Rally. There are also many smaller, club level, categories of rallies which are popular with amateurs, making up the "grass roots" of motor sports. Cars at this level may not comply fully with the requirements of group A or group N homologation. Rallying is the most widely used motor sport around the world as it can race on any circuit type. As well as the WRC other major rally events include the British Rally Championship, Intercontinental Rally Challenge, African Rally Championship, Asia-Pacific Rally Championship and endurance rally events like the Dakar Rally.
