In Pixar's Cars 2, what is the name of the worldwide race series featuring three major events?

In Pixar's Cars 2, the worldwide race series featuring three major events is the World Grand Prix.

The World Grand Prix is organized by Miles Axlerod to promote Allinol, a supposedly clean alternative fuel. Lightning McQueen enters the competition, while Mater becomes involved in Finn McMissile and Holley Shiftwell's espionage investigation. This arrangement makes the race series both a sporting contest and the setting for the film's international mystery.

The three events take place in Tokyo, Porto Corsa, and London. Competitors include Lightning, Francesco Bernoulli, and Shu Todoroki. The locations broaden the franchise beyond Radiator Springs and give Cars 2 a different visual and narrative scale from the first film.

The World Grand Prix should not be confused with the Piston Cup, which is the recurring American stock-car championship associated with Lightning's earlier career. Cars 2 was directed by John Lasseter and Brad Lewis and released in 2011.
