In Pixar’s Cars 2, what event does Lightning McQueen enter around the world?

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

The fictional event is organized as a three-race international competition to promote Allinol, an alternative fuel. The races take place in Tokyo, Porto Corsa, and London, giving the film its worldwide setting.

McQueen competes for the United States, while Mater becomes entangled in a spy operation after being mistaken for an American agent. The apparent racing competition conceals a plot involving manipulated Allinol and a weapon that causes cars to malfunction.

The World Grand Prix is not the same competition as the Piston Cup. The Piston Cup is the principal American stock-car championship in the Cars universe, while the World Grand Prix is an international event created specifically for Cars 2.
