Cars 2 takes Lightning McQueen and Mater to the World Grand Prix.
Released in 2011, the film begins with McQueen accepting an invitation to compete in a new international racing series. Mater becomes involved in an espionage plot after being mistaken for an American secret agent, shifting the story toward global adventure.
The World Grand Prix visits fictionalized versions of Tokyo, Porto Corsa, and London. The races also introduce the alternative-fuel debate surrounding Allinol and the criminal scheme led by Professor Zündapp.
Cars 2 differs from the original film by giving Mater the central role and expanding the setting beyond Radiator Springs. Cars 3 returned to a more focused racing story about McQueen’s competition with Jackson Storm, so it is not the film associated with the World Grand Prix.
