In Cars 2, what is the name of the international racing series featuring Lightning McQueen?

The World Grand Prix is the international racing series featuring Lightning McQueen in Cars 2.

The series is organized by Miles Axlerod, a former oil baron who presents it as a global competition for energy-efficient cars. Its three principal races take place in Tokyo, Porto Corsa, and London, giving the film an international spy-adventure structure.

Lightning McQueen enters the World Grand Prix after being challenged by Italian race car Francesco Bernoulli. Mater accompanies him and becomes involved in an espionage plot involving modified fuel and a group of disguised villains.

The World Grand Prix is fictional, but its locations and presentation draw on real international motorsport events. It should not be confused with the Piston Cup, the domestic racing championship central to the first Cars film and still important to Lightning's identity.
