Touring car racing

Touring car racing is a style of road racing that is run with production-derived four-seat race cars. The lesser use of aerodynamics means following cars have a much easier time following and passing than in open-wheel racing. It often features full-contact racing with subtle bumping and nudging due to the small speed differentials and large grids.

The major touring car championships conducted worldwide are the Supercars Championship (Australia), British Touring Car Championship, Deutsche Tourenwagen Masters (DTM), World Touring Car Championship and the World Touring Car Cup. The European Touring Car Cup is a one-day event open to Super 2000 specification touring cars from Europe's many national championships. While Super GT traces its lineage to the now-defunct JGTC, the cars are much more similar to GT3 race cars than proper touring cars, and also have much more aggressive aerodynamics.

The Sports Car Club of America 's SPEED World Challenge Touring Car and GT championships are dominant in North America. America's historic Trans-Am Series is undergoing a period of transition, but is still the longest-running road racing series in the U.S. The National Auto Sport Association also provides a venue for amateurs to compete in home-built factory-derived vehicles on various local circuits.
