What is the name of the racecourse in Pixar’s Cars where the Piston Cup season finale is held?

Motor Speedway of the South is the racecourse where Pixar’s Cars opens and stages its Piston Cup season finale.

The film begins with a three-way tie involving Lightning McQueen, Chick Hicks, and The King. Their final race at the Motor Speedway of the South is interrupted when Lightning’s selfish actions contribute to a three-car finish, leading officials to order a tiebreaker in California.

That setup drives the central plot. Lightning is transported toward the tiebreaker but becomes separated from his trailer and ends up in Radiator Springs, where he is forced to repair the damage he caused and reconsider his priorities.

The fictional speedway should not be confused with the later Los Angeles International Speedway, the venue used for the tiebreaker race. The two tracks serve different story purposes in Cars.
