What is the name of the international race held in Pixar's Cars 2?

The international race held in Pixar's Cars 2 is called the World Grand Prix.

The competition is organized by Sir Miles Axlerod and takes place across three major locations: Tokyo, Porto Corsa, and London. Lightning McQueen enters as a representative of the United States, while Mater accompanies him and becomes entangled in the film's spy plot.

The World Grand Prix is designed to promote Allinol, an alternative fuel. A group of villains secretly manipulates the race and the fuel system to cause damaging incidents, creating the story's central conspiracy. The event therefore functions both as a sporting contest and as the setting for the film's international espionage narrative.

The World Grand Prix should not be confused with the Piston Cup, the domestic racing championship associated with McQueen in the first and third films. Cars 2 expands the series from American stock-car racing to a worldwide event.
