Sprint cars are small, high-powered race cars designed primarily for the purpose of running on short dirt or paved tracks. Sprint car racing is most popular in the United States, but series also operate in Australia and New Zealand.
Sprint cars have a high power-to-weight ratio making sprint car racing exciting with speeds in excess of 140 miles per hour on some tracks. This speed often also makes it very dangerous. The safety record of sprint car racing in recent years has been greatly improved by the use of roll cages to protect the drivers. Wings have been mounted on top of the cars since the 1970s to give them sufficient downforce so as not to become airborn as readily as was previously the case. When cars went airborn, the wings would break off or absorb the impact of the flip, lessening the impact on the driver. In some cases, teams are able to replace the wing during the ensuing red flag and be able to race once the race resumed.
Many NASCAR drivers got their start in sprint car racing, including Jeff Gordon and Tony Stewart. As a challenging form of auto racing, sprint car racing is considered an excellent training ground for NASCAR series.
