Founded in 2006 by award-winning Massachusetts Institute of Technology-trained aeronautical engineers and management whizkids, Terrafugia is a company with a mission: to provide innovative solutions to the challenges facing personal aviation.
The result: the Transition Roadable Aircraft.
Its unique design allows the Transition to fold its wings and drive on any surface road with a modern personal airplane platform.
Once at the airport, the wings extend and the aircraft is ready.
Powered testing of the Proof of Concept has been ongoing since the second half of 2008.
Construction, testing and certification of the Production Prototype will follow completion of the Proof of Concept’s testing program.
First customer delivery of a Transition Roadable Aircraft is expected to occur in 2011.
To date, Terrafugia remains privately funded by a group of accredited individual investors.
The company is based just outside Boston in Woburn, Massachusetts, USA.

Dimensions
Folded:
6 feet 9 inches tall 6 feet 8 inches wide 18 feet 9 inches long
 
Airplane:
6 feet 3 inches tall 19 feet 2 inches long
 
Wingspan:
27 fee 6 inches
 
Cockpit:
51 inches at the shoulder The Transition can take off or land at any public use general aviation airport with at least 2,500 feet of runway.
On the ground, the Transition can be driven on any road and parked in a standard parking space or household garage. Once on the ground, with the wings folded, the vehicle can be driven on any road.
The Transition is powered by a certified aircraft engine that runs on unleaded automotive gasoline.

Perfect for trips between 100 and 500 miles, the Transition is not designed to replace anyone’s automobile. 

After landing, the pilot activates the electro-mechanical wing folding mechanism from inside the cockpit.
The wings fold, once at the root and once at the mid-span, and are stowed vertically on the sides of the vehicle in less than 30 seconds.
Simultaneously, the engine power is directed to the front wheels with a continuously variable transmission.
Before flying, the pilot extends the wings and performs a standard preflight. The engine power is directed to the propeller for flight through a carbon fibre drive shaft.
If bad weather is encountered en route, the pilot can land and drive without worrying about ground transportation.
At the destination airport the pilot can fold the wings and drive off the airfield without having to move bags or arrange for additional transportation.
Driving and flying can be combined between multiple airports as it is not necessary to take off and land at the same field.

Terrafugia has completed flight testing of the Transition POC (Proof of Concept). Introducing the Transition®. Simply land at the airport, fold your wings up and drive home. 
 
Fly a distance of 725 kilometers at speeds of 115 km/hour; Requires a special license to drive and fly. 
The time required for the transition from plane to car takes less than 30 seconds. Vehicle speed 185 km/hour, range is 724 km on highways  Vehicle is fueled with gasoline, and the price of the car is expected  to be around $200,000. The first shipment will be in 2011
