Former champion Doc Hudson's plate is "51HHMD," which is the real license plate of the original 1951 Fabulous Hudson Hornet. Doc is not only the town doctor, but also the town judge and also a retired racecar. His license plate reads 51HHMD (a reference to his year (1951), model (Hudson Hornet) and profession (medical doctor)). Doc was once known as the Fabulous Hudson Hornet (#51), one of the most famous racecars to have ever lived; he won three Piston Cups, and still holds the record for most wins in a single season.
The car is based on the real-life Fabulous Hudson Hornet in NASCAR competition driven by Herb Thomas and Marshall Teague. A reality Hudson Hornet themed on Doc that was used to promote the film's release is on display at the Volo Auto Museum.The character of Hudson himself is most likely based on his voice actor Paul Newman, who was one of the film screen legends during his prime at his younger age, but his mainstream film acting career fades as he got older, similar to how Doc Hudson's racing career faded away.
The Hudson Hornet is an automobile that was produced by the Hudson Motor Car Company of Detroit, Michigan between 1951 and 1954. The Hornet was also built by American Motors Corporation in Kenosha, Wisconsin and marketed under the Hudson brand between 1955 and 1957.
The Hornet dominated stock car racing in the early-1950s, when stock car racers actually raced stock cars.
