What is the name of the race venue in Florida where Pixar's Cars 3 reaches its climax?

The climactic race venue in Florida in Pixar's Cars 3 is Florida International Super Speedway.

The fictional speedway hosts the decisive Piston Cup race where Cruz Ramirez takes over for Lightning McQueen and challenges Jackson Storm. Its full name distinguishes it from the other invented tracks appearing across the Cars films.

The setting provides a large, modern arena for the film's final competition. This contrasts with Thomasville, where Lightning trains with Cruz and Smokey, and with Radiator Springs, where Lightning learned the value of community in the first film.

The venue is sometimes confused with the Motor Speedway of the South, the fictional track used for the opening race in Cars. Cars 3 also includes other racing locations, but Florida International Super Speedway is the specifically named Florida venue associated with the finale.
