From Wikipedia: The console versions of the game are set in the fictional town of Radiator Springs, where it takes place after the movie. The player must compete in 19 road races, 8 mini-games, and 5 piston cup races to help Lightning McQueen win his first Piston Cup. In the PSP version, the game presumably takes place on an alternate timeline. The player must compete in 13 races, as well as 5 boss races, to help Lightning McQueen force the Delinquent Road Hazards gang to depart Radiator Springs early. The game takes place in a open world in the vein of Need for Speed, Grand Theft Auto and Midnight Club and features ten playable characters from the film (16 in the PSP version), all voiced by the original voice talent.[3][4] The game also features a number of minigames and items for the player to collect.
