In Pixar's Cars 3, which character trains Lightning McQueen before racing him?

In Pixar's Cars 3, Cruz Ramirez trains Lightning McQueen before racing him.

Cruz is introduced as a performance trainer at the Rust-eze Racing Center. She uses modern coaching methods and simulation technology to help McQueen prepare for his comeback after Jackson Storm's rise. Their relationship begins with McQueen resisting her methods, but the partnership gradually becomes more respectful and collaborative.

Cruz is voiced by Cristela Alonzo. Her own racing ability is initially overlooked because she has spent years helping others rather than competing at the highest level. The story eventually reveals that she has the speed, determination, and racing instincts to compete herself.

Cruz's role changes substantially during the film, which can cause confusion about the answer. She is both McQueen's trainer and, later, his racing successor in the climactic storyline. Sally Carrera is McQueen's friend and romantic partner, while Flo runs the local café in Radiator Springs; neither serves as his professional trainer.
