Touring car racing is a style of road racing that is run with production-derived race cars. It often features full-contact racing 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), and the World Touring Car Championship. The European Touring Car Cup is a one-day event open to Super 2000 specification touring cars from Europe's many national championships.
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.
