Cruz Ramirez initially works as a trainer at the Rust-eze Racing Center in Pixar’s Cars 3.
She is assigned to help Lightning McQueen prepare for competition against Jackson Storm, a younger and faster racer. Cruz uses modern training technology, simulation, and data-driven methods, creating an early contrast with McQueen’s traditional experience and instinct.
During the story, Cruz’s own racing ability becomes increasingly important. McQueen realizes that she has the potential to compete, and she eventually becomes a racer rather than remaining only a trainer. Cristela Alonzo provides Cruz’s voice. The character’s career change is a major part of the film’s generational theme, but her initial job at the training center is specifically that of a trainer.
