In Pixar's Cars 2, which global racing event is used as the setting for the spy conspiracy?

The World Grand Prix is the global racing event used as the setting for the spy conspiracy in Pixar's Cars 2.

The competition is created by Miles Axlerod to promote Allinol, an alternative fuel. It consists of races in Tokyo, Porto Corsa, and London, giving the film an international structure that differs sharply from the American road-racing focus of the first Cars movie.

The event's public purpose is to demonstrate that Allinol can power cars competitively. Behind the scenes, however, a group of criminals manipulates the fuel and uses electromagnetic weapons to make racers appear to fail. The conspiracy is designed to discredit alternative fuel and benefit petroleum interests.

Lightning McQueen enters the races, while Mater becomes involved with Finn McMissile and Holley Shiftwell's investigation. The World Grand Prix therefore serves two functions: it is the film's sporting contest and the mechanism that connects its spy plot across several countries.
