The Florida 500 is the final race Lightning McQueen enters in Pixar's Cars 3.
The event is the season-ending Piston Cup race at the Florida International Super Speedway. Lightning initially prepares to compete against the younger high-tech racer Jackson Storm, but the race develops into a turning point for both Lightning and Cruz Ramirez.
The Florida 500 echoes the structure of famous real-world American motorsport events while remaining fictional within the Cars universe. Its location gives the film a large, modern racing venue that contrasts with the older tracks and small-town roads associated with Lightning's earlier career.
The race name is sometimes confused with the Piston Cup itself. The Piston Cup is the championship competition, while the Florida 500 is the specific race that concludes the film's season.
