In Pixar’s Cars 2, the fictional fuel associated with the World Grand Prix is Allinol.
Allinol is presented as an alternative fuel developed and promoted by Miles Axlerod, the former oil baron who becomes a central figure in the film’s conspiracy. The World Grand Prix is created to demonstrate that Allinol can power high-performance race cars, bringing competitors together for races in Japan, Italy, and the United Kingdom.
The fuel’s apparent environmental promise is part of the deception. Professor Zündapp and the lemons use electromagnetic pulses to make cars running on Allinol explode or malfunction. Their scheme is intended to discredit alternative fuel and increase demand for traditional petroleum products.
Allinol is a fictional product created for the Cars universe, not a real commercial fuel. Cars 2 also uses real-world visual inspiration: the World Grand Prix cars, locations, and spy-film structure are designed to evoke international motorsport and classic espionage stories.
