The Transition is described as the world's first flying automobile. It is due to take to the air next month.
The Terrafugia Transition was developed by former Nasa engineers.
The car is powered by a 100bhp engine, used on both the ground and in the air.The manufacturers say the car will be able to fly up to 500 miles on a single tank of petrol.It reportedly has a cruising speed of 115mph..
The company is based in Massachusetts. It can transform itself from a two-seater car on the road into a plane within, the makers say, 15 seconds.
If it survives next month's flight, the car/plane is expected to go on sale to the public in about 18 months' time.
Designer Car Dietrich says there are 40 orders in for the machine, which costs around £132,000.
However, its makers insist that is still a good price for an aeroplane.
There are a couple of potential problems: insurance and take-off locations - it is generally illegal to take off from a road.
