In Pixar’s Cars 2, what international championship does Lightning McQueen enter?

In Pixar’s Cars 2, Lightning McQueen enters the World Grand Prix.

The World Grand Prix is a three-race international competition organized by oil magnate Sir Miles Axlerod. Its stated purpose is to promote Allinol, a new alternative fuel. The races take place in Tokyo, Porto Corso, and London, giving the film a globe-spanning setting unlike the first Cars movie, which concentrates largely on Radiator Springs and the American road.

Lightning competes against Francesco Bernoulli and other international racers. Mater becomes involved in a spy adventure after being mistaken for an undercover agent, and the racing plot becomes connected to a scheme involving Allinol and a hidden weapon. The World Grand Prix is fictional, so it is not the same event as Formula One, the real-world World Rally Championship, or any actual international racing series.
