In Pixar's Cars 2, what competition is called the World Grand Prix?

In Pixar's Cars 2, the World Grand Prix is an international race series.

The competition is organized by Sir Miles Axlerod to promote Allinol, a new alternative fuel. It takes Lightning McQueen, Mater, and their companions to races in locations including Tokyo, Porto Corsa, and London. The races form the film's main sporting storyline.

Cars 2 expands the franchise beyond Radiator Springs by combining racing with a spy-adventure plot. Lightning competes for the World Grand Prix title, while Mater becomes involved with secret agents who are investigating a conspiracy connected to the fuel and the race.

The World Grand Prix is fictional, although its format borrows visual ideas from real international motorsport. It should not be confused with the Piston Cup, the domestic stock-car-style championship featured prominently in the first and third Cars films.
