In Pixar's Cars 2, the competition held in three international locations is the World Grand Prix.

The World Grand Prix is organized by Miles Axlerod as a global racing event intended to promote Allinol, an alternative fuel. Its three races take the characters to Porto Corso in Italy, London in the United Kingdom, and Tokyo in Japan.

Lightning McQueen enters the event after being challenged by Italian racer Francesco Bernoulli. Mater travels with him and becomes entangled with British agents Finn McMissile and Holley Shiftwell, who are investigating sabotage connected to the races.

The competition is important because it links the film's racing plot with its spy plot. What first appears to be a straightforward international tournament becomes the public stage for a scheme involving fuel, remote-control technology, and criminal manipulation.
