What is the international racing competition called in Pixar's Cars 2?

The international racing competition in Pixar's Cars 2 is the World Grand Prix.

The World Grand Prix is organized by billionaire businessman Miles Axlerod to promote alternative fuel. It takes competitors to three major race locations: Tokyo, Porto Corsa, and London. Lightning McQueen enters the event, while Mater becomes involved in an international spy operation after being mistaken for an American agent.

The competition gives Cars 2 a broader setting than the original film's American stock-car world. Its events combine fictional racing with recognizable international locations and landmarks, including London's Big Ben and Tokyo's urban landscape.

The story's spy plot centers on a conspiracy involving Allinol, the event's promoted fuel. The World Grand Prix should not be confused with the Piston Cup, which is the domestic racing championship central to Lightning's career in the first film.
