What is the name of the fictional racecourse in Pixar's Cars 3 finale?

The fictional racecourse in Pixar's Cars 3 finale is Florida International Super Speedway.

The track hosts the climactic final Piston Cup race, where Lightning McQueen competes against the younger high-tech racer Jackson Storm. McQueen begins the race, but Cruz Ramirez takes over late in the event after McQueen encourages her to race.

The name resembles real American speedways while remaining a fictional setting created for the film. Its Florida location also connects the finale to the film's broader training and racing storyline, which moves between real-world-inspired venues and invented Cars locations.

This track should not be confused with the Motor Speedway of the South, the fictional venue used for the opening race of the first Cars film. The Piston Cup is the championship, whereas Florida International Super Speedway is the specific circuit hosting Cars 3's finale.
