Who trains Lightning McQueen in the main racing program of Pixar's Cars 3?

Cruz Ramirez trains Lightning McQueen in the main racing program of Pixar's Cars 3. She is a young yellow race technician and trainer at the Rust-eze Racing Center before becoming a racer herself.

Lightning initially arrives at the center after struggling against faster, technologically advanced competitors such as Jackson Storm. Cruz uses modern training tools, including simulators and exercise equipment, but Lightning's impatience creates friction between them. Their relationship changes as both characters confront assumptions about what they are capable of doing.

Cruz has dreamed of racing, yet she has been placed in a training role rather than being treated as a serious competitor. Lightning eventually recognizes her talent and encourages her to enter the competition. She becomes an important part of the film's message about mentorship, confidence, and passing opportunity to a new generation.

Sally Carrera is Lightning's friend and love interest, while Holley Shiftwell belongs to Cars 2's spy storyline. Neither character trains Lightning in Cars 3.
