Which Pixar Cars film introduced Cruz Ramirez?

Cars 3 introduced Cruz Ramirez.

Cruz is introduced as Lightning McQueen's high-tech trainer at the Rust-eze Racing Center. She is a yellow sports coupe with advanced simulator and training knowledge, but she has also dreamed of becoming a racer herself. Her role changes when Lightning's struggle against Jackson Storm reveals that her abilities extend beyond coaching.

Cars 3 uses Cruz's story to explore confidence, opportunity, and the difference between a person's assigned role and their actual potential. Lightning initially treats her as part of a training program designed to keep him competitive, but their relationship develops into a partnership. Cruz ultimately becomes an important racer in the film's final act.

Cruz should not be confused with Holley Shiftwell, the British spy car from Cars 2, or Sally Carrera, Lightning's friend in Radiator Springs. Cruz belongs specifically to the third feature film and is voiced by Cristela Alonzo. She also appears in later Cars-related media.
