In Pixar's Cars, what make and model is Doc Hudson?

In Pixar's Cars, Doc Hudson is a 1951 Hudson Hornet.

The character is based on the real Hudson Hornet, an American automobile produced by Hudson from 1951 to 1954. The Cars version reflects the model's distinctive rounded body and its reputation as a powerful stock car. In the film, Doc is the respected town doctor in Radiator Springs, but he is secretly a former racing champion.

Doc's racing history connects the fictional character to the real Hornet's competition success. Hudson Hornets became famous in early-1950s NASCAR and stock-car racing, helping establish the car as an important performance sedan. A common mix-up is calling Doc a generic Hudson or identifying him as a later model; the film specifically presents him as a 1951 Hudson Hornet.
