A hover car is a personal vehicle that flies at a constant altitude of up to a few meters (yards) above the ground and used for personal transportation in the same way a modern automobile is employed. The concept usually appears in science fiction.
In science fiction, it is capable of elevating itself some distance from the ground through some repulsion technology, presumably exploiting some short range anti-gravity principle so as to eliminate most friction forces which act against conventional vehicles. Other works feature vehicles that hover by having magnetic plates lined along roads, operating in a similar principle to Maglev. The capability of hovering above the ground eliminates the need for tires, and unlike an air-cushion vehicle, it does not produce a dust cloud.
The closest devices are the hovercraft, which elevates itself above a water or level hard surface using a cushion of air retained by a flexible skirt, and the hovertrain, which is a type of high-speed train that replaces conventional steel wheels with hovercraft lift pads, and the conventional railway bed with a paved road-like surface, known as the "track" or "guideway".
