The Piston Cup is the trophy awarded to the season’s top racer in Pixar’s Cars.
Lightning McQueen is competing for the Piston Cup when the film begins. A three-way tie between McQueen, Chick Hicks, and The King leads to a final race at the Los Angeles International Speedway, setting the story in motion.
The Piston Cup is a fictional championship prize created for the Cars universe. Its name evokes the piston, a major component of an internal-combustion engine, and it functions as the franchise’s equivalent of a premier stock-car racing championship.
Doc Hudson’s past is closely tied to the trophy: he won three Piston Cups before retiring. In Cars 3, the championship remains important as McQueen confronts the rise of younger racers. The Piston Cup should not be confused with the World Grand Prix, the international competition central to Cars 2.
