Stock Car Racing

Stock car racing, the North American equivalent to touring car racing, is that continent's most-popular form of auto racing in terms of viewership. Usually conducted on ovals, the cars may slightly resemble production cars but are in fact purpose-built racing machines which are built to tight specifications. Early stock cars were actual production vehicles, the car to be raced was often driven from track to track. 

The modern car however is far removed from the production model which it represents, making the term "stock car" somewhat incorrect.

The largest stock car racing governing body is NASCAR. NASCAR's premier series is the Sprint Cup Series, its most famous races being the Daytona 500 and the Brickyard 400. NASCAR also runs several feeder series. The Nationwide Series, and Craftsman Truck Series (a pickup truck racing series) conduct races across the entire continental United States. The NASCAR Canadian Tire Series conducts races across Canada and the NASCAR Corona Series conducts races across Mexico. NASCAR also governs several smaller regional series.

NASCAR also governs the Whelen Modified Tour. Modified cars are best described as hybrids of stock cars and open-wheel cars. They are heavily altered from stock, with powerful engines, large tires, tubular chassis and light bodies. The Whelen Modified tour is NASCAR's oldest series.

There are also other stock car governing bodies, such as Automobile Racing Club of America and United Speed Alliance Racing.

British Stock car racing is a form of Short Oval Racing. This takes place on shale or tarmac tracks in either clockwise or anti-clockwise direction depending on the class, some of which allow contact. 

Races are organized by local promoters and all drivers are registered with BRISCA and have their own race number. What classes exist depends on the promoter, so events in Scotland at Cowdenbeath can be very different from an event at Wimbledon Stadium in London.
