Sprint cars are high-powered race cars designed primarily for the purpose of running on short oval or circular dirt or paved tracks. Sprint car racing is popular in the United States, Canada, Australia, New Zealand and South Africa.
Sprint cars have a high power-to-weight ratio, making speeds in excess of 140 miles per hour (230 km/h) possible on some tracks. This speed often also makes racing sprint cars very dangerous.

Sprint cars are high-powered race cars designed primarily for the purpose of running on short oval or circular dirt or paved tracks. Sprint car racing is popular in the United States, Canada, Australia, New Zealand and South Africa.
Sprint cars have a high power-to-weight ratio, making speeds in excess of 140 miles per hour (230 km/h) possible on some tracks. This speed often also makes racing sprint cars very dangerous. is commonplace for these machines. The safety record of sprint car racing in recent years has been greatly improved by the use of roll cages to protect the drivers. Many IndyCar and NASCAR drivers used sprint car racing as an intermediate stepping stone on their way to more high profile divisions, including Jeff Gordon, Kasey Kahne,Tony Stewart, J. J. Yeley, P. J. Chesson, Sarah Fisher, and Ed Carpenter.
For a complete history of sprint car racing, the National Sprint Car Hall of Fame & Museum located in Knoxville, Iowa, USA features exhibits to highlight the history of both winged and non-wing sprint cars.
Non-winged Sprint Cars
There are a few sanctioning bodies for non-winged sprint cars. The United States Automobile Club (USAC) has become the premier series for non-winged sprint car racing throughout the United States, especially after taking over the Sprint Car Racing Association (SCRA) and turning it into the USAC/California Racing Association (USAC/CRA). This series has become the premier non-winged sprint car series on the west coast of the United States. USAC also has hosted the Silver Crown series based in the Midwestern United States state of Indiana for decades. The Silver Crown series was started in 1971 as an offshoot of the series that competed for the National Championship Trail including the Indianapolis 500, known as "big cars".
Winged Sprint Cars
The world's first winged car, known today as a winged sprint car, was created and driven by Jim Cushman at the Columbus Motor Speedway (Ohio) in 1958. In the early 1970s, many sprint car drivers began to put wings with sideboards on both the front and top of their cars. The added wings increased the downforce generated on the car, with the opposite direction of the sideboards helping to turn the car in the corners. This makes the car easier to control. The added downforce also lessens the likelihood of going airborne. When cars do go airborne, the wings frequently break off or absorb some of the impact of the flip, lessening the impact on the driver. Wings on sprint cars help to provide down force resulting in increasing traction. Wings also provide an amount of protection for the driver in case of an accident and are sometimes referred to as "aluminum courage." In some cases, teams are able to replace the wing during the ensuing stoppage and are able to race once the race resumed.With the addition of wings, a new sanctioning body and touring series to promote the sport was founded. In 1978, Ted Johnson formed the leading promotional body for winged sprint cars called the World of Outlaws.
Racing throughout the United States from March to November, the World of Outlaws is the premier dirt sprint car racing series. Famous tracks featured in the series included the Eldora Speedway in Rossburg, Ohio, the Knoxville Raceway in Knoxville, Iowa and Williams Grove Speedway in Mechanicsburg, Pennsylvania. Each August, the Knoxville Raceway holds the paramount sprint car event, the Knoxville Nationals.
Sanctioning bodies
The World of Outlaws (WoO) is a division of winged sprint cars that run all over the United States and have a few events in Canada. The cars have wide right rear tire and a 410 cubic inch engine with mechanical fuel injection. These sprint cars have no battery or a starter in them, necessitating a push start by a quad or truck. This is done both for weight reasons and tradition. Another tradition the WoO has for their A-main (the last race of the event) they line up four wide just before starting the race.
The United States Automobile Club (USAC) is a division of sprint cars that run throughout the United States. They race non-winged 410 cubic inch sprint cars on asphalt and dirt tracks.
The United Racing Company (URC) is a division for winged sprint cars that run mainly in the northeastern part of the United States in Pennsylvania, New Jersey, and Delaware. URC started in 1948 with 11 races in its season. It slowly progressed to 28 races. URC uses a 360 cubic inch engine which generates approximately . They race with alcohol fuel and use mechanical fuel injection (MFI) to deliver it to into the combustion chamber.
Television coverage in the United States
Non-winged cars were televised first when USAC had an ESPN television contract. The first national live television deal with winged sprint cars came on The Nashville Network (TNN) in 1992-93 and again in 1993-94 with a winter-based series in Arizona, which featured Mike Joy calling the action. Live coverage of the Knoxville Nationals on The Nashville Network began in 1995. A year later, a next-day tape deal with CBS for one race at Eldora Speedway aired while TNN coverage expanded. By 2000, CBS (which owned TNN at the time) announced TNN would air 15 live events, including the King's Royal at Eldora Speedway and the Knoxville Nationals. By the 2001 season, plans were to cover 18 live races, but midway through the season MTV Networks closed the CBS motorsports operations. This move relegated the remainder of the World of Outlaws season to tape delay races. A tape delayed deal with the SPEED Channel followed for the next season. Television coverage began on the The Outdoor Channel in 2003. Events are usually tape delayed for two weeks or more. The Knoxville Nationals were on Speed Channel. The 2005 Knoxville Nationals did not air as bad weather postponed the event, and there was not enough space for Speed to air the event, won by Kraig Kinser. In 2003, Johnson sold his organization to DIRT Motorsports. Because of complaints about DIRT Motorsports and the lack of television coverage, Northwest Sprint Tour owner Fred Brownfield formed the National Sprint Tour as a rival to the World of Outlaws Sprint for the 2006 season. Notable teams in the NST included Steve Kinser Racing (#11), Roth Motorsports (sometimes known as the "Beef Packers" team) (#83), Tony Stewart Racing (#20). After Brownfield Promotions' owner Fred Brownfield was killed in a crash, Kinser and principals of two other teams purchased the entire Brownfield promotion. That series folded after the 2006 season, while the Northwest tour, a regional tour, was sold. The SuperClean Summer of Money aired on ESPN2 starting in mid June 2008 with the World of Outlaws at Knoxville Raceway and for 8 weeks straight leading up to the Knoxville Nationals which were live on SPEED.
Safety Aspects
The safety record of sprint car racing in recent years has been greatly improved by several new mandatory safety regulations including the use of roll cages to protect the drivers, fuel tank bladders to prevent fuel leakage, requirements to use a five-point safety harness seatbelt two years old or newer, and driver suit standards to consist of two layers and rated at least SFI 3.5. In addition, drivers must wear nomex driving gloves. Other equipment requirements include: helmets must be full coverage and must exceed snell 95 rating; arm restraints systems must be used; cars must have a 1/8 inch wire debris/rock screen in the front roll cage opening covering the entire opening; and headrests mandatory on the right side of the drivers seat.
