What type of real-world car inspired the design of Doc Hudson in Pixar’s Cars?

Doc Hudson’s design was inspired by the 1951 Hudson Hornet.

The Hudson Hornet was an American automobile produced by the Hudson Motor Car Company. Its low, streamlined body and strong stock-car racing reputation made it a natural basis for Doc Hudson, whose hidden past is that of the Fabulous Hudson Hornet.

The real Hudson Hornet became especially famous in early stock-car racing. Drivers such as Marshall Teague and Herb Thomas helped establish the model’s competition reputation during the early 1950s. The car’s engineering and distinctive “step-down” body construction also made it recognizable among classic American vehicles.

Pixar combined those historical details with a fictional character voiced by Paul Newman. Doc is not a literal biography of one racer, and the film changes names and events for its story. His model is nevertheless a specific Hudson Hornet rather than a generic vintage sedan, which connects the character to a real chapter of American racing history.
