What fictional racing competition is held around the world in Pixar's Cars 2?

The fictional racing competition in Pixar's Cars 2 is the World Grand Prix.

Cars 2 follows Lightning McQueen as he enters the World Grand Prix, a three-race international event created by former Formula One driver Sir Miles Axlerod. The races take place in Tokyo, Porto Corsa, and London.

The competition is promoted as a showcase for alternative fuel, with race cars using Allinol. The apparent sporting event becomes part of a spy plot involving Axlerod, a secret group of lemons, and a dangerous broadcast weapon. Mater is mistaken for a spy and becomes central to the investigation.

Cars 2 was released in 2011 and directed by John Lasseter and Brad Lewis. Unlike the first film's small-town road story, its plot uses international locations, espionage, and racing technology as major elements.
