In Pixar's Cars 2, which global racing competition is used to promote Allinol fuel?

The World Grand Prix is used to promote Allinol fuel in Pixar's Cars 2.

Sir Miles Axlerod organizes the international race and presents Allinol as a clean alternative fuel. Lightning McQueen enters the competition, while Mater becomes entangled in the spy mission surrounding the event.

The World Grand Prix visits three major race locations: Tokyo, Porto Corsa, and London. These settings give the sequel a globe-spanning structure unlike the mostly American-road setting of the first Cars.

The event is more than a sporting contest because its publicity campaign is connected to the film's espionage plot. The Piston Cup, by contrast, is the domestic championship associated most strongly with the original film and Cars 3.
