In Pixar's Cars 2, what is the name of the global race featuring Tokyo, Porto Corsa, and London?

In Pixar's Cars 2, the global race featuring Tokyo, Porto Corsa, and London is the World Grand Prix.

The event is organized as a three-race competition to promote Allinol, a new alternative fuel. Lightning McQueen enters for the racing challenge, while Mater becomes involved in Finn McMissile’s investigation surrounding the event.

The World Grand Prix gives Cars 2 an international structure that differs from the first film’s American Piston Cup setting. Its courses pass through recognizable fictionalized versions of major locations, including Tokyo, the Italian coastal city of Porto Corsa, and London.

The World Grand Prix is sometimes confused with the Piston Cup because Lightning is the same central racer. The Piston Cup is the domestic championship from the first film, whereas the World Grand Prix is the international competition introduced in the sequel.
