Which car defeats Lightning McQueen in the final race of Pixar's Cars 3?

Cruz Ramirez defeats Lightning McQueen in the final race of Pixar's Cars 3.

The film's climax takes place at the Florida 500, where Lightning begins the race against the technologically advanced Jackson Storm. After an early setback, Lightning changes strategy and gives Cruz the opportunity to compete. Cruz uses the racing knowledge and confidence she has developed during their training to enter the contest and ultimately win.

Cruz is introduced as Lightning's trainer at the Rust-eze Racing Center. Although she initially works as a coach rather than a professional racer, she has racing ambitions of her own. Lightning's decision to support her reflects the film's theme of passing experience to a new generation rather than treating retirement as failure.

Lightning remains central to the victory because he helps Cruz discover her ability and creates the chance for her to race. However, Cruz is the driver who crosses the finish line first. Jackson Storm is the modern rival she defeats at the Florida 500.
