Blindsided by a new generation of blazing-fast cars, the legendary Lighting McQueen finds himself pushed out of the sport that he loves. Hoping to get back in the game, he turns to Cruz Ramirez, an eager young technician who has her own plans for winning. With inspiration from the Fabulous Hudson Hornet and a few unexpected turns, No. 95 prepares to compete on Piston Cup Racing's biggest stage.
Wanting to get back on the winners’ list, he approaches Rust-eze, who is now owned by Sterling. Sterling is a fan of McQueen but has suggested he spend his days endorsing Rust-eze new products instead. However McQueen makes a deal that if he wins, he will decide when his retirement will be and if he loses, he will retire immediately.
He went on to meet his trainer Cruz Ramirez who actually dreams of racing herself. McQueen felt the old training method was better for him so he looked for Smokey, who was his mentor Doc’s mentor. There he learned that Doc continued to feel victorious in the race by mentoring him when he was no longer capable of winning himself.
When the next racing season began, it slowly dawned on McQueen that it is time to mentor instead of racing and, he gets Cruz to race for him. Cruz wins and continued to race with McQueen as her trainer.
