Doc Hudson is the retired race car who serves as Radiator Springs' doctor in Pixar's Cars. He is also the town's judge and initially hides his former life as a famous racer.
Doc was once the Fabulous Hudson Hornet, a three-time Piston Cup champion. His racing career ended after a crash caused by a rookie driver, and he became bitter about being forgotten by the racing world. McQueen's arrival gradually brings those memories back.
Paul Newman provided Doc Hudson's voice in Cars, one of the actor's final major film performances. The character is based on the real Hudson Hornet, a car associated with stock-car racing success in the early 1950s. Doc's history teaches McQueen that winning is not the only measure of a racing life.
