What fictional racing championship is central to Pixar’s Cars?

The Piston Cup is the fictional racing championship central to Pixar’s Cars.

Lightning McQueen competes in the Piston Cup season and travels toward the final race after tying with veteran racer Strip Weathers and rival Chick Hicks. The championship gives McQueen his career ambition and explains why he is rushing across the country when he becomes separated from his transport truck.

The Piston Cup is modeled broadly on American stock-car racing, especially the spectacle, sponsorships, pit crews, and oval-track competition associated with NASCAR. Its name also echoes the mechanical language of engines and automobile performance. Dinoco is the prestigious fictional sponsor connected with the championship, not the name of the championship itself.

Cars 2 shifts attention to the World Grand Prix, an international event with races in Tokyo, Porto Corsa, and London. Cars 3 returns to the Piston Cup world and places McQueen in competition with newer racers such as Jackson Storm. These separate competitions are a frequent source of mix-ups.
