Lightning McQueen and the other veterans racers of the Piston Cup suddenly find themselves struggling to win against next-generation rookies like Jackson Storm who utilize advanced technology and modern training methods. As Storm's breakout success attracts other rookies to the series, most of the veterans either retire or are fired to make way for the new generation. In the final race of the season, McQueen rushes a pit stop and desperately attempts to overtake Storm, but overworks and blows a shaky tire, losing control and suffering a violent crash.
