In Pixar's Cars 3, who trains Lightning McQueen with modern racing technology?

In Pixar's Cars 3, Cruz Ramirez trains Lightning McQueen with modern racing technology.

Cruz is introduced as a high-tech trainer at the Rust-eze Racing Center. She uses tools such as racing simulators, performance data, and specialized exercises to help McQueen respond to a new generation of faster competitors. McQueen initially doubts her methods because he is a veteran racer accustomed to traditional experience and instinct.

The film gradually changes the relationship between the two characters. Cruz is not merely a coach assigned to improve McQueen; she is also a talented racer whose own ambitions have been overlooked. When she gets a chance to compete, her speed and determination become central to the story.

Cristela Alonzo provides Cruz's voice. The character helps Cars 3 explore questions about aging, mentorship, technology, and making room for new competitors. A common mix-up is identifying Cruz as McQueen's permanent replacement from the beginning. She starts as his trainer, and her racing role develops later in the film.
