What is the name of the racing stadium where the Piston Cup finale occurs in Pixar's Cars?

The Piston Cup finale in Pixar's Cars occurs at Los Angeles International Speedway.

The race is the decisive event of the film's season-long competition. Lightning McQueen, Chick Hicks, and the retiring champion Strip Weathers—better known as The King—arrive at the stadium with the championship at stake. The event takes place after Lightning's unplanned stay in Radiator Springs, where he has developed friendships and a different understanding of success.

The stadium name is fictional, but its presentation draws on real American stock-car racing venues. The Piston Cup itself is a fictional championship modeled in part on the culture and visual language of NASCAR. Lightning's decision during the race, especially his response to Chick Hicks's dangerous driving, becomes more important to the story than simply finishing first.

This venue is separate from the Florida International Super Speedway in Cars 3. It is also not the same as the real California Speedway, now known as Auto Club Speedway, despite the similar regional setting.
