What racing competition is organized in Pixar's Cars 2?

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

The event is created by Sir Miles Axlerod to promote Allinol, a new alternative fuel. Lightning McQueen enters the competition, and Mater travels with him as part of the team. The races take the characters to major international locations.

The World Grand Prix gives Cars 2 its global setting. Its races include Tokyo, Porto Corsa, and London, unlike the first film's focus on the fictional Radiator Springs area and the Piston Cup circuit.

The Piston Cup remains important to the Cars franchise, but it is not the central competition in Cars 2. The movie combines the international race with a spy plot involving Mater, British agents, and a conspiracy surrounding Allinol.
