Designer Greg Brown and engineer Dave Fawcett are finessing a design for a jet-propelled car that can reach speeds up to 550 miles in the air, but then converts into a zero-emissions electric car on the ground. Over the last few years flying cars like the Terrafugia Transistion and the Skylys have provided a realistic glimpse into the future of flying cars. The idea of a jet-propelled flying car has been missing, but the GF7 could bridge that divide if it comes to life.

Brown and Fawcett are currently based in Napa, California where they are hoping to create a four-passenger flying car that can travel up to 1,000 miles in the air, but at the same time easily drive up to 120 miles on the ground.

How does it work? On the ground the GF7 drives like a standard car with its four wheels and wings folded up. It can reach speeds up to 100 mph and the 50 kWh battery pack has a range that’s on par with electric vehicles at between 80-120 miles. Upon take off the wheels retract into the fuselage and the wings fold down with a wing span of 23 feet. The jet engine also recharges the battery pack during flight. Unlike the Terrafugia, the GF7 can fly at altitudes up to 38,000 feet high.

Brown and Fawcett hope to have a flying prototype completed in four years. Unfortunately, the GF7 won’t be cheap with a price tag expected between $3-5 million. At that price the GF7 is priced about the same as other small jet aircraft, but other models can’t drive on the street like the GF7 can.
