This film is placed in a world populated by anthropomorphic transportation, including cars, trucks, fire engines, suvs, among others. The story is focused on a race car called Lightning McQueen, who dreams to win the Piston Cup in order to change his sponsorship. McQueen needs to win a race between Strip "The King" Weather and Chick Hicks, after a triple-tie. He wants to change Rust-Eze, a rust treatment for old cars, to take The King's place as the sponsored car of the lucrative Dinoco team.

This tiebreaker race will be competed in Los Angeles, and since it is a long distance, McQueen wants to travel in his big rig, Mack, the whole night. In the way to LA, the door where Lightning was sleeping opens, a he gets lost in the middle of the highway. He desperately tries to follow a path, and without knowing he arrives in a town called Radiator Spring. At first, he dislikes everything and everyone in the town, doing community service repairing the street. He takes orders from Doc Hudson, who turns out to be the "Fabulous Hudson Hornet", inspiring McQueen to do things better in the town and helping in the repair of the street by his own.

Later, he finds out that he is in a town that was famous because it passed through the U.S. Route 66, but when the Interstate 40 was built it disappeared from the map. Consequently, Lightning starts to be friendly with everyone, specially with a tow truck named Mater and a porsche named Sally; Mater is consider to be his best friend, while Sally his girlfriend. Finally when he is found in Radiator Spring he competes in LA against Chick and The King. In the middle of the race he wasn't focused until his pit staff talks to him and were Hudson with more friends from the town. In the last lap Hicks sends Weathers into a dangerous accident. Seeing this, McQueen stops just short of the finish line, allowing Hicks to win, and drives back to push Weathers over the finish line. He ends up like a hero and receives an offer to sign for Dinoco, but he refuses and stay with his actual sponsorship because of the support given to him.
