Meanwhile, in Ornament Valley, in front of the Rustbucket Stadium, Mater meets his old rivals, Bubba, Tater and Tater Jr., who reminded him of when they agreed a long time ago to race in the Rustbucket Stadium for the towing rights to Radiator Springs.

Lightning McQueen arrives at Santa Carburera with Doc's students and a few of his friends from Radiator Springs.

Candice loses the race, despite being promised by her father that she would win, so she calls him and asks him to buy a bunch of new car parts for her, to which he agrees.

El Machismo loses the races, making him angry, and blames it on Chick and MotorCo., and demands for bigger car parts.

Before the final race, Chick introduced Stinger (the strong silent type) to Lightning and Ramone.

Lightning McQueen and Chick Hicks go back to Radiator Springs Speedway for the final round in the Race-O-Rama series.

Right before the race, Chick reveals that he was only using Candice, El Machismo, Stinger and the VINs to learn how to beat Lightning.

Later, Candice, El Machismo and Stinger show up to readily apologize to Lightning for their past behavior.

Lightning happily accepts their apology and gladly invites them to come to the Doc Hudson Racing Academy any time.

During these events the player participates in combat racing similar to that found in the Mario Kart series.

In his starting configuration, the player can change McQueen's front bumper, hood, side skirts and spoiler.

The PSP and DS versions of the game were created by Tantalus Media in Melbourne and Brisbane, Australia.
