In Pixar’s Cars 2, what international race is organized to promote the alternative fuel Allinol?

In Pixar’s Cars 2, the World Grand Prix is organized to promote the alternative fuel Allinol.

The event takes Lightning McQueen and Mater around the world for races in Japan, Italy, and England. Its public purpose is to demonstrate that Allinol can power high-performance cars, while the competition also creates the setting for a larger espionage plot.

The World Grand Prix gives Cars 2 a global structure unlike the mostly American road-trip setting of the first film. Locations include Tokyo, Porto Corso, and London, allowing the filmmakers to build action sequences around recognizable international environments.

The Piston Cup is a separate racing competition from the first Cars film and remains associated with American stock-car racing. Although several Cars characters participate in both kinds of events, the international Allinol showcase in Cars 2 is specifically called the World Grand Prix.
