In Pixar's Cars 2, what competition is held across several international locations?

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

The race is organized by Sir Miles Axlerod as a showcase for an alternative fuel called Allinol. Its three principal races take place in Tokyo, Porto Corsa, and London, bringing Lightning McQueen into competition with international racers such as Francesco Bernoulli.

The World Grand Prix gives Cars 2 a much broader setting than the first film. Instead of focusing mainly on one American town, the sequel moves between major world locations and combines racing with a spy adventure involving Mater. The competition is also central to the film's plot because the Allinol races become connected to a conspiracy involving the Lemons.

The event is fictional, but its format draws on real international motorsport series and grand tours. It should not be confused with the Piston Cup, the domestic stock-car championship associated with McQueen in the first and third films.
