We now have hoverboards, so are hover cars on the horizon? If designer Kevin Clarridge has his way, this insane Audi concept will be the car of the future. The sleek automobile has no axles or wheels, instead acting as a maglev-powered (magnetic levitation) hover vehicle. The low friction ride also notes zero emissions and is capable of reaching incredibly high speeds.

Will we be cruising around in these in decades to come? If not, the car would be a great addition to an upcoming sci-fi film.
