In the Back to the Future franchise, the DeLorean time machine is a time travel device made by retrofitting a DMC DeLorean vehicle with a flux capacitor. The car requires 1.21 gigawatts of power and needs to travel 88 miles per hour (142 km/h) to initiate time travel. Universal Studios special effects department built three main DeLorean time machines for the movie Back to the Future. The film's producers characterized the DeLoreans with three names: the A car, B car, and C car. The "A" car, also known as the Hero car, was the most detailed and utilized vehicle during production.[1] After filming was over, the "A" car was delivered to Universal Studios Hollywood as an attraction piece. As time passed, visitors started taking parts off the vehicle and wandering off with them. Bob Gale selected a team to repair the car so it could be in a perfect condition. The vehicle is currently being displayed at the Petersen Automotive Museum in Los Angeles.[2] The "B" car, also known as the Stunt Car used in all three movies, was mainly used for stunts. After purposely being struck by a train during production, the car was left as a pile of rubble. Movie car customizer Jay Ohrberg used the "B" car wreckage to construct various DeLorean replicas. The "B" car's body panels were sold to Planet Hollywood Hawaii, where it was hooked up on the ceiling of the restaurant until its shutdown in 2010. The car was sold at auction to Bill and Patrick Shea after Back to the Future HQ reached out to Planet Hollywood to find the car's remains. The stunt car is currently being displayed at Hubbardston, Massachusetts.[3][4] The "C" car was used for interior footage and was torn apart so the camera could fit inside the car. The vehicle was left at Universal Studios Hollywood, many of its parts were put together on a replica remodeled by Tom Talmon Studios for Universal Japan. Universal Japan sold the car to a private company and the vehicle is currently being displayed on the company's entryway.[4] There were three extra DeLoreans used through the production of the sequels. The fiberglass car used on special effects was reportedly destroyed. The stunt train, better known as The Oxnard Car, was displayed in Universal Studios, Florida, from the early 1990s to 2020. The studio decided to replace the original car with a replica to be stored for restoration. The desert car with the blue cross over tube was left at Universal Studios Hollywood; Tom Talmon Studios used parts of this car on a replica displayed on Universal Japan. After Japanese workers stole some of the car props, ScreenUsed acquired the car for restoration and then settled the car for auction. Bill and Patrick Shea ended up buying it, and they placed the car on display at Hubbardston, Massachusetts.[3]
