Transition aircraft.

The Transition is a roadable aircraft under development by Terrafugia, a start-up company based in Woburn, Massachusetts.
The Rotax 912S piston engine powered, carbon-fiber vehicle is planned to have a flight range of 400 nmi (460 mi; 740 km) using automotive grade unleaded gasoline and a cruising flight speed of 115 mph (185 km/h; 100 kn).

On the highway, it can drive up to 80 mph (130 km/h) to keep up with traffic.

The Transition prototype’s folded dimensions of 6 ft 9 in (2.1 m) high, 6 ft 8 in (2.0 m) wide and 18 ft 9 in (5.7 m) long are designed to fit within a standard household garage.

Interesting first step, although it’ll be marketed as a light aircraft you happen to be able to drive to and from the airport, rather than a car which flies. 🙂
