What was the title of the fictional racing championship in Pixar’s Cars 2?

The World Grand Prix is the fictional racing championship in Pixar’s Cars 2.

The competition is organized as an international series to promote Allinol, an alternative fuel presented by its creator, Miles Axlerod. Lightning McQueen enters the races, while Mater becomes entangled in a spy investigation surrounding the fuel and the events affecting the competitors.

The World Grand Prix visits Tokyo, Porto Corsa, and London. These locations give Cars 2 a globe-spanning structure that differs from the first film’s focus on Radiator Springs and the Piston Cup.

The Piston Cup remains an important fictional American racing championship in the Cars universe, but it belongs chiefly to Lightning McQueen’s domestic racing career. It is therefore not the name of the international contest in Cars 2.
