Dirt track racing has a following of 30 million loyal fans across most of the United States, and it sells 52 million tickets each year, which amounts to more tickets sold than NASCAR, NBA, NFL, and NHL combined. World of Outlaws, with more than 140 annual event nights, more than 1.2 million live fans, and two national touring series to choose from, is the pinnacle of dirt track racing. The first of these touring series is the Sprint Car Series, where drivers race machines with the classic winged frame. The second is the Late Model Series, which uses cars with a sleeker, more traditional racing frame.
Most NASCAR drivers have started their careers tangling with the dirt track, and some, like Tony Stewart, were not only champions on dirt once, but also have returned later as car owners. Stewart owns the car that championship driver Donny Schatz races in the World of Outlaws Sprint Car Series.
Established in 1978, the Sprint Car Series now has 95 event nights and more than 700,000 live fans. The 850-horsepower Sprint Car machines are taken to speeds of over 140 miles per hour on dirt tracks as short as a quarter mile, which gives a pretty darn good picture of the intensity fans love so much.
