In Pixar's Cars 2, what racing event is held in Japan, Italy, and England?

In Pixar's Cars 2, the racing event held in Japan, Italy, and England is the World Grand Prix.

The World Grand Prix is organized by Miles Axlerod to promote Allinol, a new alternative fuel. Its races take place in Tokyo, Porto Corso, and London, giving Cars 2 a global setting unlike the primarily American locations of the first film.

Lightning McQueen enters the competition, while Mater becomes entangled in the film's spy storyline after British agents mistake him for an undercover operative. The combination of international racing and espionage makes Cars 2 structurally different from the original Cars.

The World Grand Prix is fictional, but its locations draw on real cities and cultural imagery. Porto Corso is a fictional Italian coastal city created for the film. The Piston Cup, by contrast, is the major stock-car racing championship associated with the first and third films.
