In Pixar's Cars 2, what racing event takes place in three countries?

The World Grand Prix is the racing event that takes place in three countries in Pixar's Cars 2.

The competition is organized by former racer Miles Axlerod to promote Allinol, a new alternative fuel. Its three races are held in Tokyo, Porto Corsa, and London, giving the film an international structure.

Lightning McQueen competes for Team Lightning McQueen, while Mater travels with him and becomes entangled in Finn McMissile's investigation. The race itself is connected to the film's larger conspiracy involving Allinol and a group of cars opposed to the fuel.

The World Grand Prix is separate from the Piston Cup, the American stock-car championship featured in Cars. The first Cars focuses on Lightning's attempt to win the Piston Cup, whereas Cars 2 combines international racing with spy-film elements.
