In Pixar's Cars, which race does Lightning McQueen enter after the Piston Cup final ends in a tie?

In Pixar's Cars, Lightning McQueen enters a tiebreaker race after the Piston Cup final ends in a tie.

The film's opening race ends with Lightning, Chick Hicks, and The King finishing in a result that cannot produce a single champion. The officials therefore schedule a new race at the Los Angeles International Speedway one week later to determine the winner.

Lightning's journey to that race is interrupted when he becomes lost and is forced to stay in Radiator Springs. Although he initially cares only about winning, his relationships with the town's residents alter his priorities before the decisive event.

The tiebreaker is not a separate named championship such as the later World Grand Prix. It is the concluding Piston Cup race of Cars, where Lightning ultimately chooses sportsmanship over an easy victory.
