Stock car racing

Stock car racing is a form of automobile racing run on oval tracks and road courses measuring approximately 0.25 to 2.66 miles (0.4 to 4.3 km). It originally used production-model cars, hence the name "stock car", but is now run using cars specifically built for racing. It originates from the United States and Canada; the world's largest governing body is the American NASCAR. Its NASCAR Cup Series is the premier top-level series of professional stock car racing. Australia, New Zealand, Mexico, Brazil and the United Kingdom also have forms of stock car racing.[1] Top-level races typically range between 200 and 600 miles (322 and 966 km) in length.

Top-level stock cars exceed 200 mph (322 km/h)[2][3][4] at speedway tracks and on superspeedway tracks such as Daytona International Speedway and Talladega Superspeedway.[5][6] Contemporary NASCAR-spec top-level cars produce maximum power outputs of 860–900 hp[7][8] from their naturally aspirated V8 engines. In October 2007 American race car driver Russ Wicks set a speed record for stock cars in a 2007-season Dodge Charger built to NASCAR specifications by achieving a maximum speed of 244.9 mph (394.1 km/h) at Bonneville Speedway.[9][10] For the 2015 NASCAR Cup Series, power output of the competing cars ranged from 750 to 800 hp (560 to 600 kW).[11][12]
