Race cars from all racing categories were invited to the event, but there was no winner at the final race, as it was interrupted by a series of anomalies that finally ended in Miles Axlerod's reformation. The World Grand Prix is the target of a plot to sabotage the race, directed by the evil weapons designer Professor Z. The British master spy Finn McMissile discovered the conspiracy and organized himself to stop it. At the end of the movie, it was discovered that the whole World Grand Prix was a setup by Miles Axlerod just to turn the world against alternative fuels.
In the first WGP, the races were sabotaged. In the first race, Acer and Grem blew the engines of Miguel Camino, Rip Clutchgoneski and Max Schnell with a hiden electromagnetic pulse emittor. After an error of Lightning McQueen, Francesco Bernoulli won the first race in Tokyo. At the second race in Porto Corsa, three other engines were blasted, those being of Carla Veloso, Nigel Gearsley and Shu Todoroki. The explosion of Shu's engine caused him to spin, and caused multi-car pileup. Lightning McQueen won the race. At the last race in London, the race was suspended because Mater entered the track and brought Lightning with him off the course. After the surprise, Miles Axlerod was arrested due to the whole event being controlled by him in an attempt to twist people's opinion of alternative fuel. Due to the London race being suspended, The WGP ends up held in McQueen's hometown, Radiator Springs.
