What is the name of Doc Hudson’s real-life racing model in Pixar’s Cars?

Doc Hudson is based on the Hudson Hornet in Pixar’s Cars.

Doc is a 1951 Hudson Hornet, a real American car associated with stock-car racing in the early 1950s. In the film, he was once a celebrated racer and a three-time Piston Cup champion before a crash ended his career.

The Hudson Hornet gained real racing fame through the “Fabulous Hudson Hornet” driven by racers including Herb Thomas, Marshall Teague and Tim Flock. Its success helped make the model an important part of early NASCAR history.

Viewers sometimes identify Doc only as a generic vintage sedan. His distinctive model name is significant because it connects the fictional character to a specific, historically notable racing car.
