Project Satan

Project Satan was a military project. He was constructed from the most evil parts of the most evil cars in the world. Some pieces includes: Project Satan is the first thing that transmitted the Were-Car curse to Calculon, while he was still a robot arm. He lived in the Anti-Chrysler Building, where he was destroyed by the Planet Express Crew in 3001.
 * Steering wheel from Hitler's staff car
 * Left Turn signal from Charles Manson's Volkswagen
 * Windshield Wipers from the car that played Knight Rider
 * Ed Begley's electric motor, the most evil propulsion system ever conceived

Trivia

 * Since Project Satan was made by cannibalizing the parts of other cars, he is more like Frankenstein's monster than a werewolf.
 * Despite running on an electric motor, Project Satan still makes the sound of an internal combustion engine when it drives.
 * Though KITT himself was not evil, his windshield wipers were (it didn't come up much in the show).
