In Pixar's Cars 2, what competition forms the movie's international racing circuit?

In Pixar's Cars 2, the World Grand Prix forms the movie's international racing circuit. The event is created to promote Allinol, an alternative fuel introduced by former oil magnate Miles Axlerod.

Lightning McQueen enters the competition after being challenged by race car Francesco Bernoulli. The World Grand Prix has races in Tokyo, Porto Corsa, and London, giving the sequel a much broader setting than the original film's American road-trip story. Mater travels with McQueen and becomes entangled in the parallel spy plot.

The World Grand Prix is not the same event as the Piston Cup. The Piston Cup is the domestic stock-car championship central to Cars, while the World Grand Prix is an international series created for Cars 2. This distinction matters because McQueen's decision to race abroad drives the sequel's main storyline.
