Doc Hudson is a car of few words but many talents. He not only serves as the town judge, he's also Radiator Springs' resident doctor. Doc is respected and admired by the townsfolk for the way he looks out for their health and tends to their aches and pains. No one knows too much about Doc's life before he came to town. He keeps his private life private. But if you've got a bad spark plug or a rattle in your engine, his door is always open.
- Doc won 3 Piston Cups during his racing career, but sadly, a big crash in 1954 ended his racing career.
- Doc is based off of the real 1951 Hudson Hornet.
