What is the name of the race held in Cars 3's climactic final competition?

The climactic final competition in Cars 3 is called the Florida 500.

The race takes place at the fictional Florida International Super Speedway. Lightning McQueen enters the event after training with Cruz Ramirez and preparing to challenge Jackson Storm, the leading representative of a faster new generation of racers.

The Florida 500 is important because it becomes more than a test of Lightning's speed. During the race, Lightning recognizes Cruz's ability and gives her the opportunity to compete in his place. Cruz ultimately wins, while Lightning begins a new role as her mentor and adopts a livery inspired by Doc Hudson.

The event is sometimes confused with the Piston Cup, which is the championship competition in the series rather than the specific final race name. The Florida 500 also echoes real American stock-car racing events, while remaining a fictional race in the Cars universe.
