In Pixar's Cars, which fictional racecourse hosts the final Piston Cup tiebreaker?

In Pixar's Cars, Los Angeles International Speedway hosts the final Piston Cup tiebreaker.

Lightning McQueen, Strip Weathers, and Chick Hicks finish the season with equal points, so the championship cannot be decided by the regular standings. The tiebreaker takes place at the Los Angeles International Speedway, where the three drivers compete for the Piston Cup.

Lightning reaches the event after his time in Radiator Springs, but his priorities have changed. He chooses to help The King after Chick's dangerous maneuver causes a crash. That decision costs Lightning the championship victory, yet it defines the sportsmanship he has learned from Doc Hudson and the town's residents.

Chick Hicks wins the official race, but the film frames Lightning's choice as the more meaningful result. The fictional speedway is not the same as a real Los Angeles circuit; it is a Cars setting created to support the film's final racing sequence and championship stakes.
