In Pixar's Cars 3, who becomes the new racer for Rust-eze Racing?

In Pixar's Cars 3, Cruz Ramirez becomes the new racer for Rust-eze Racing.

Cruz begins as Lightning McQueen's high-tech trainer at the Rust-eze Racing Center. She is younger and more technically advanced than McQueen, but she has always wanted to compete rather than coach. After McQueen's difficult season and his decision to challenge the new champion Jackson Storm, Cruz's racing ability becomes central to the story.

Near the climax, McQueen gives Cruz the opportunity to race in his place. She wins the Florida 500, and Rust-eze later signs her as its new racer while McQueen adopts a mentor role. Cruz is not simply a replacement created by the team at the start of the film: her promotion follows her own discovery of confidence and racing talent. Cristela Alonzo provides Cruz's English-language voice.
