Race cars from all racing categories were invited to the event, but there was no winner, as the final race 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 set up 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 broke the engines of Miguel Camino, Rip Clutchgoneski and Max Schnell. After an error of Lightning McQueen, Francesco Bernoulli won the first race in Tokyo. At the second race in Porto Corsa, other three engines were broken. First the engine of Carla Veloso, then Nigel Gearsley's engine. The third engine broken was Shu Todoroki's engine. After the explosion, Shu spins, and Miguel Camino hits him. After the contact, also Max Schnell hits Shu Todoroki. Also, Rip Clutchgoneski and Raoul CaRoule arrive in a terrible crash, where Shu Todoroki risked his life. Fortunately, Lewis Hamilton and Jeff Gorvette braked before the accident who involved five cars. 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. After the surprise, Mater unmasked Miles Axlerod. Due to the suspended London Race, the 4th World Grand Prix ends up in Lightning McQueen's hometown, Radiator Springs.
