Lightning McQueen, portrayed by Owen Wilson, finds himself racing alongside his old friends, Bobby Swift and Cal Weathers. The trio shares a deep bond, often playfully swapping victory through the races they attend. However, during one key event, a rival racer, Jackson Storm, zooms past them, leaving Lightning astonished as he watches the replay on the Jumbotron. The loud and brash announcer, Chick Hicks—who was once Lightning’s adversary—teams up with Natalie Certain, a brilliant statistician, to cover the rise of this new generation of racers. They point out Jackson’s outstanding skills, which seemingly rely on advanced technology that allows him to outperform seasoned champions.

As Lightning grapples with his performance amidst a growing number of high-tech competitors, he soon learns that Cal and other veterans are either retiring or being replaced—a tough break for an established icon like him. In the midst of this, he faces a significant blow during a race when a catastrophic tire blowout sends him rolling and ultimately breaks him down. Fast forward four months, and we find Lightning recuperating in Radiator Springs. While reflecting on past moments with his mentor, Doc Hudson, he recalls some of Doc’s wisdom: > “You think I quit? They quit on me.” Encouraged by his love interest Sally, played by Bonnie Hunt, he resolves to start training again.

Lightning contacts his sponsors Rusty and Dusty, who reveal that they’ve opened a new racing training facility managed by a new owner, Sterling, played by Nathan Fillion. Sterling introduces him to Cruz Ramirez, a savvy trainer portrayed by Cristela Alonzo.

Their first sessions are tumultuous, with Lightning crashing on the simulator multiple times due to his stubbornness and impatience.

Realizing that he and Cruz must work together, Lightning decides to take her to Fireball Beach for practical training, where they struggle initially but ultimately find success through perseverance. Their bond grows stronger, and Cruz gains confidence as she trains under Lightning, who also begins to rediscover his own racing potential. However, as Lightning prepares for a major race, he learns about the upcoming event circumstances: he would start at the back of the pack since he missed qualifiers, with Jackson off to a fast lead.

Amidst the chaos of the race day, Lightning finds himself in a position where he must rely on Cruz, realizing she possesses the skills and heart of a true racer. Cruz, stepping up to fill in, faces Jackson head-on, proving herself fiercely competitive. In a thrilling final lap, she remembers Doc’s incredible maneuvering and executes a daring move that leads her to victory, earning the respect she deserves and revealing Lightning’s guidance was right.

After the thrilling conclusion, Lightning decides not only to continue racing but to assist Cruz as her pit chief.
