What is the name of the Florida racetrack where Cars 3 begins?

Cars 3 begins at the Florida International Super Speedway.

The track hosts a Piston Cup race where Lightning McQueen faces Jackson Storm and other next-generation competitors. The sequence establishes the film's central problem: Lightning remains a champion in experience and reputation, but newer racers have technological and performance advantages.

Florida International Super Speedway is a fictional racing venue created for the Cars universe. Its name echoes real American motorsport tracks while fitting the series' habit of inventing locations and businesses through automotive wordplay.

The race ends with a serious crash after Lightning pushes his car too hard while trying to keep pace. That accident leads his sponsor to demand a training plan and sends him to the Rust-eze Racing Center, where Cruz Ramirez helps him prepare for a return. Thomasville Speedway is another fictional track important later in the film, but it is not the opening venue.
