Which car is Lightning McQueen's mentor in Pixar's Cars?

Doc Hudson is Lightning McQueen's mentor in Pixar's Cars.

After McQueen is stranded in Radiator Springs, Doc initially acts as a stern judge who wants the disruptive rookie to leave. Their relationship changes when McQueen learns that Doc was once the Fabulous Hudson Hornet, a three-time Piston Cup winner whose career ended after a serious crash.

Doc teaches McQueen more than racing technique. He demonstrates patience, humility, and respect for the people of Radiator Springs. The training sequences also reveal that Doc still understands racing at a very high level, despite having withdrawn from the sport.

The King is an older champion who serves as a racing role model, but he is not McQueen's principal mentor in the film. Doc's mentorship is central to McQueen's transformation from an individualistic rookie into a more thoughtful competitor and friend.
