In Pixar's Cars, which race is held in Los Angeles to decide the Piston Cup champion?

In Pixar's Cars, the Dinoco 400 is the race held in Los Angeles to decide the Piston Cup champion. The event is the season finale and features Lightning McQueen, Chick Hicks, and The King in a three-way contest.

A three-car tie at the season's end leads officials to schedule the race. McQueen is focused on winning the championship and securing the prestigious Dinoco sponsorship, while veteran champion The King is attempting to finish his final season with another title.

The race is remembered for McQueen's decision to help The King after Chick Hicks causes him to crash. McQueen gives up the victory celebration and chooses sportsmanship, allowing Hicks to win the official race but losing the Dinoco opportunity. The finale establishes the film's central lesson about character and competition.
