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.

In the films, the DeLorean time machine is a licensed, registered vehicle in the state of California, where the films take place. The vanity license plate used in the film reads "OUTATIME", a deliberate anomaly, as the maximum number of symbols on California plates is seven characters. When Doc returns from 2015, it is a barcode license plate, which implies that by that year license plates have moved to other more sophisticated means of tracking and registering.
