About Classic Indycar: Road America
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 team owners formerly from the United States Auto Club (USAC) Championship Car division. The owners disagreed with the direction and leadership of USAC. They developed a then-novel business model of team owners sanctioning and promoting their own series collectively rather than relying on a neutral governing body to do so.
