The Champ Car World Series was a premier open-wheel racing series in North America, known for its high-speed competition and skilled drivers. Established in 1979, it featured a mix of road courses and street circuits, attracting fans with its exciting races and advanced technology in car design. The series was originally part of the CART (Championship Auto Racing Teams) organization but became independent in the early 2000s. It faced challenges, including competition from IndyCar, leading to a decline in popularity. The last season took place in 2007, after which it merged with IndyCar Series, marking the end of its distinct identity.
