Yeah, something like the (even more) heavily modified DeLorean Doc Brown returned with from 2015. Key technologies still missing would be (a) the energy source (a "Mr. Fusion" which can generate energy from random garbage you throw into it) and (b) some kind of levitation not based on rotors, rockets or jet engines (anti-gravity?), apparently also used in the hoverboards.
