In Pixar’s Cars, which race is the season finale for the Piston Cup?

The Dinoco 400 is the season finale for the Piston Cup in Pixar’s Cars.

The film opens with the Dinoco 400 at the Motor Speedway of the South. A three-way tie between Lightning McQueen, Chick Hicks, and The King leads to a final race at the Los Angeles International Speedway to determine the champion.

The Piston Cup is a fictional racing championship modeled broadly on American stock-car competition. Dinoco is its most prestigious sponsor in the film and is represented by The King, whose blue-and-orange appearance makes the brand especially recognizable.

The Dinoco 400 is not the final race shown in the story; that distinction belongs to the tiebreaker race in Los Angeles. The Florida 500 is the major race in Cars 3, while the World Grand Prix belongs to Cars 2, so these event names should not be substituted.
