The Hudson Hornet is a full-sized automobile which was produced by the Hudson Motor Car Company of Detroit, Michigan, between 1951 and 1954 and then by American Motors Corporation (AMC) in Kenosha, Wisconsin, and marketed under the Hudson brand between 1955 and 1957. The first-generation Hudson Hornets featured a functional "step-down" design with dropped floorpan and a chassis with a lower center of gravity than contemporary vehicles that helped the car handle well – a bonus for racing. The Hornet's lower and sleeker look was accentuated by streamlined styling, sometimes called "ponton" styling. The Disney Pixar film Cars and several spin-off video games featured a Fabulous Hudson Hornet named Doc Hudson, a retired Piston Cup champion. The Piston cup is the franchise's version of the Winston Cup Series.
