At least that’s what Michael Cole, the boss of car manufacturer Hyundai’s European arm reckons.

For now, prototypes look less like a DeLorean and more like a plane and a car had a dirty affair and produced offspring. Take the imaginatively named AirCar, which successfully completed a 35-minute flight in Slovakia yesterday. Kitted out with a BMW engine, it takes just 2 minutes to transform from a car into a plane, and its creators say it can fly for 1,000km at speeds of up to 170km/hour.
