Touring car racing is a style of road racing that is run with production derived race cars. It often features exciting, full-contact racing due to the small speed differentials and large grids.
The V8 Supercars originally from Australia, British Touring Car Championship, Deutsche Tourenwagen Masters originally from Germany, and the World Touring Car Championship held with 2 non-European races (previously the European Touring Car Championship) are the major touring car championships conducted worldwide, along with a European Touring Cup, 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 while the venerable British Touring Car Championship continues in the United Kingdom. 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.
