In Pixar's Cars, what name did Doc Hudson use as a champion racer?

In Pixar's Cars, Doc Hudson raced as the Fabulous Hudson Hornet.

Before becoming Radiator Springs' doctor, Doc was a celebrated stock-car driver known by the nickname the Fabulous Hudson Hornet. He won three Piston Cup championships and was recognized for his skill on dirt tracks. His racing career ended after a crash, followed by a period in which the racing world largely ignored him.

The name draws on the real Hudson Hornet, a Hudson automobile that became famous in early NASCAR competition. Real Hudson Hornets used advanced engineering and strong performance to achieve notable racing success during the early 1950s. Pixar adapted that history into Doc's fictional biography.

Doc's title is sometimes shortened to “Hudson Hornet,” but the full racing name used in Cars is the Fabulous Hudson Hornet. The character's history explains why he can coach Lightning McQueen so effectively: he understands both the technical demands of racing and the emotional cost of being discarded by the sport.
