In Pixar's Cars 3, Lightning McQueen competes against Jackson Storm in the Florida 500.
The Florida 500 is the climactic race of the film. It takes place at the fictional Florida International Super Speedway, where McQueen attempts to prove that he can still compete with the younger, technologically advanced racers led by Storm.
McQueen begins the season struggling against Storm, a next-generation racer whose speed and modern training methods expose the veteran's limitations. With help from his trainer Cruz Ramirez, McQueen prepares for the decisive event and enters the Florida 500 as part of his effort to remain a competitive Piston Cup racer.
The race is also important because it changes Cruz's role in the story. A late decision allows her to race, creating the film's final sporting turning point. The Florida 500 should not be confused with the Piston Cup, which is the championship series and trophy featured across the Cars films.
