Championship Auto Racing Teams (CART) was a sanctioning body for American open-wheel car racing that operated from 1979 until dissolving after the 2003 season. CART was founded in 1979 by United States Auto Club (USAC) Championship Division team owners who disagreed with the direction and leadership of USAC, with the then-novel idea of team owners sanctioning and promoting their own series collectively instead of relying on a neutral body to do so. Through the 1980s, CART's Indy Car World Series became the pre-eminent open-wheel auto racing series in North America, featuring street circuits, road courses, and oval track racing. CART teams continued to compete at the USAC-sanctioned Indianapolis 500, which was effectively integrated into the series schedule.
