What role does Lightning McQueen take near the end of Pixar's Cars 3?

Near the end of Pixar's Cars 3, Lightning McQueen becomes Cruz Ramirez's crew chief.

The change follows McQueen's realization that his career can continue in a new form after the younger racer Jackson Storm surpasses him. McQueen supports Cruz during the Florida 500, where she takes his place and defeats Storm.

After the race, McQueen adopts a new paint design inspired by his mentor Doc Hudson. He keeps racing selectively, but his main professional role shifts toward helping Cruz develop as a competitor. This completes the film's story about mentorship, changing generations, and finding purpose beyond personal victory.

McQueen does not become Cruz's permanent replacement as a racer or an official Piston Cup administrator. Crew chief is the precise racing role shown in the film, linking him to the pit strategy and guidance that Doc once provided for him.
