In Pixar's Cars 3, who is the yellow trainer assigned to help Lightning McQueen?

In Pixar's Cars 3, Cruz Ramirez is the yellow trainer assigned to help Lightning McQueen.

Cruz is a young Hispanic-American race car and performance trainer at the Rust-eze Racing Center. Cristela Alonzo provides her voice. She initially approaches Lightning with modern simulation exercises and data-driven training techniques, but their relationship changes after he decides to train outside the center.

Lightning and Cruz travel to places connected with the history of racing, including Thomasville, where they meet Smokey and learn about Doc Hudson's past. Cruz's own ambition gradually becomes an important part of the story. Although she begins as a trainer, she has the talent and determination to compete herself.

The film's final act makes Cruz central to the franchise's themes of mentorship and opportunity. Her yellow design and number 51 distinguish her from Lightning's red number 95.
