Sprint cars are high-powered open-wheel race cars, designed primarily for the purpose of running on short oval or circular dirt or paved tracks. Historically known simply as "big cars," distinguishing them from "midget cars," sprint car racing is popular primarily in the United States and Canada, as well as in Australia, New Zealand, and South Africa.
