In the upcoming Cars 4, it's still a big question whether our beloved Lightning McQueen will return as a racer or step up as a crew chief. Given the ending of Cars 3, where McQueen takes on a mentoring role, it's possible that he might wear the crew chief hat this time. However, knowing his love for racing, we can't completely rule out his return to the race track. We'll have to wait and watch how his character evolves. Stay tuned for more updates on this exciting Pixar sequel!
