In Pixar's Cars 2, what competition is held in three cities around the world?

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

The race is organized by Sir Miles Axlerod to promote Allinol, an alternative fuel. Its three venues are Porto Corso in Italy, Porto Corso's broader European setting, and London, with Tokyo serving as the opening location.

Lightning McQueen competes for the United States, while Francesco Bernoulli represents Italy. Mater becomes involved in the spy plot surrounding the race and its fuel technology.

The World Grand Prix differs from the Piston Cup in the first film. The Piston Cup is a season-long stock-car championship, while the World Grand Prix is an international series created specifically for the sequel's story.
