Hovercar
A hovercar is a fictional transport vehicle appearing in works of science fiction. It is used for personal transportation in the same way a modern automobile is employed.
It is incapable of flying but does elevate itself some distance from the ground through some unspecified repulsion technology, presumably exploiting some short range anti-gravity principle.
The closest real-world device is the hovercraft, which elevates itself above a water or level hard surface using a cushion of air retained by a flexible skirt. Such devices are not considered to be hovercars, however — that term is used only for the fictional device.
Perhaps the best visualization of a hovercar was in the Star Wars movie episode IV (the first in the series).
