In Pixar's Cars, which famous racer is revealed to have been Doc Hudson?

In Pixar's Cars, Doc Hudson is revealed to have been the Fabulous Hudson Hornet.

Before becoming Radiator Springs' physician and judge, Doc was a celebrated race car. He won three Piston Cups, in 1951, 1952, and 1953, and earned the nickname the Fabulous Hudson Hornet. His racing career ended after a crash left him sidelined and overlooked by the racing world.

Doc's history explains his harsh attitude toward Lightning McQueen. He recognizes Lightning's arrogance and fears that the young racer may suffer the same emotional isolation that followed his own career. Doc eventually agrees to train him, using experience and strategy rather than flashy speed.

The character is based on the real Hudson Hornet, a 1950s American car that became famous in stock-car racing. The film's Doc combines that automotive history with an original fictional biography. Doc's racing number is 51, matching the year of his first Piston Cup victory.
