Cruz Ramirez wins the Florida 500 in Pixar's Cars 3 after Lightning McQueen hands over his race car.
Lightning begins Cars 3 struggling against the younger, technologically advanced racer Jackson Storm. He eventually trains with Cruz Ramirez, a former student who becomes increasingly confident as a racer.
During the Florida 500, Lightning initially races Storm but realizes Cruz deserves the opportunity to compete. He gives her his racing number and moves into the pit area. Cruz then takes the track, catches Storm, and passes him to win the race.
The victory also changes Cruz's professional role. Rather than remaining only Lightning's trainer, she becomes a successful racer for Rust-eze. Lightning continues racing as well, but the ending presents Cruz as the new generation's champion. A common mix-up is to identify Lightning as the winner because he starts the race; the film's final winner is Cruz.
