Who wins the final Piston Cup race in Pixar’s Cars 3?

Cruz Ramirez wins the final Piston Cup race in Pixar’s Cars 3.

During the film’s climactic race at the Los Angeles International Speedway, Lightning McQueen gives Cruz Ramirez the opportunity to compete against Jackson Storm. Cruz takes over for the final portion of the race and defeats Storm, earning the Piston Cup for the Rust-eze team.

The result reflects Cars 3’s central theme: McQueen’s legacy continues by helping a new racer rather than simply reclaiming his own position. Cruz began as McQueen’s highly trained racing simulator coach, but she had her own ambitions and racing ability.

Lightning’s decision also echoes Doc Hudson’s history. Doc once supported McQueen’s career after losing his own racing future. Cruz’s victory therefore becomes both a sporting result and a generational handoff within the story.
