Newman/Haas Racing was an auto racing team that competed in CART, Champ Car, and the IndyCar Series from 1983 to 2011. The team operations were based in Lincolnshire, Illinois. Newman/Haas Racing was formed as a partnership between actor, automotive enthusiast and semi-professional racer Paul Newman and long-time auto racing owner/driver Carl Haas. The duo were competitors in sports car racing during the 1970s and early 1980s. In 1983, they joined forces to enter the ranks of Indy car racing. Newman/Haas was one of the most successful teams in Indy car racing during the 1980s, 1990s, and 2000s. The team won 105 CART/Champ Car races and eight season championships, followed by two race wins in the IRL/IndyCar Series.

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.
