What is the name of the fictional speedway where Cars 3's final race is held?

Florida International Super Speedway is the fictional speedway where Cars 3's final race is held.

The climactic race in Cars 3 takes place at Florida International Super Speedway, where Lightning McQueen faces the challenge of competing in the Piston Cup season after training with Cruz Ramirez. The venue is presented as a major modern racing facility.

The setting helps distinguish the final race from earlier tracks in the film. Lightning's comeback is not simply a return to his old routine; the race becomes a turning point involving teamwork, strategy, and Cruz's abilities as a racer.

The speedway is fictional, like many locations in the Cars universe. It should not be confused with the Los Angeles International Speedway, where Lightning suffers a serious crash earlier in the film, or Thomasville Speedway, associated with his training and the history of Doc Hudson.
