The World of Outlaws (often abbreviated WoO) is an American motorsports sanctioning body. The body sanctions two major national touring series. It is best known for sanctioning the World of Outlaws Sprint Car Series and the World of Outlaws Late Model Series. These dirt track racing series are owned and operated by World Racing Group. The Sprint Car Series is sponsored by Monster Beverage's NOS Energy Drink and beginning in 2022 the Late Model Series will be sponsored by Case Construction Equipment. World of Outlaws Sprint Car Series The body sanctions a national tour of high power to weight, custom fabricated sprint cars called the World of Outlaws NOS Energy Drink Sprint Car Series. The race cars feature large adjustable wings on the top and large rear tires that transfer their power to the dirt tracks they race on. The series travels primarily the United States, but has sanctioned races in Canada, Mexico and Australia. The title sponsor is NOS Energy Drink. The series was founded in 1978 by Ted Johnson, a former midget racer from Madison, Wisconsin. At the time sprint car racing in the United States lacked a true national series. Johnson organized the World of Outlaws sanctioning body and established a national schedule, a set of rules and a points system to crown a champion of his series. In 2003, Johnson sold the series to Boundless Motor Sports Racing, later renamed Dirt Motorsports and currently World Racing Group. In 2004, the subscription-based streaming service DIRTVision was founded. It originally offered radio broadcasts of all races, and added video streaming to select races, until reaching the full calendar in 2018. Select races are broadcast on delay nationally on the CBS Sports Network with MavTV showing the Knoxville Nationals since 2013. Previous broadcasters include The Nashville Network and Speed Channel shown live or on delay. Sprint car specifications A WoO Sprint Car must weigh at least 1,425 pounds (646kg) with the driver in the car. The mandated 410-cubic inch engine (6.7 litre) produces over 900 horsepower, uses mechanical fuel injection and must run on methanol fuel. The series' specification tire manufacturer Continental AG works with the World of Outlaws to designate legal tire compounds for a circuit among different compounds available to competitors, as the tire must suitably respond to the track surface. Continental technicians will reject certain compounds at certain circuits if they are unfit for the surface
