In Pixar's Cars, what nickname does Lightning McQueen use for Doc Hudson?

In Pixar's Cars, Lightning McQueen uses the nickname The Hudson Hornet for Doc Hudson.

Doc is introduced as Radiator Springs' judge and medical practitioner, but Lightning eventually learns that he was once a celebrated race car. He competed as the Hudson Hornet and won three consecutive Piston Cups before a crash ended his racing career.

The character is based on the real Hudson Hornet, a full-size American car produced by the Hudson Motor Car Company. The real model became famous in stock-car racing during the early 1950s, particularly through its success in NASCAR. Pixar used that history to give Doc a believable but hidden past.

The phrase is a racing identity rather than merely a description of Doc's color or profession. “The Fabulous Hudson Hornet” is associated with the character's racing legend, while the canonical car name is Hudson Hornet.
