In Pixar’s Cars, which character has the racing number 51?

In Pixar’s Cars, Doc Hudson has the racing number 51.

Doc’s number refers to his championship-era identity as the Fabulous Hudson Hornet. In the story, he once dominated the Piston Cup before a serious crash ended his racing career and left him frustrated with the sport. He later settles in Radiator Springs and serves as the town’s doctor.

The number 51 is displayed on the Hudson Hornet associated with Doc’s past. It distinguishes him from Lightning McQueen, whose racing number is 95, and from the other Piston Cup competitors seen in the film.

Doc’s racing history is important because he initially refuses to help Lightning. Their relationship changes when Doc recognizes Lightning’s potential and eventually becomes his crew chief. The character is voiced by Paul Newman in Cars, one of Newman’s final major film roles.
