The Terrafugia Transition is a light sport, roadable airplane under development by Terrafugia since 2006.[4]
The Rotax 912ULS[5] piston engine powered, carbon-fiber vehicle is planned to have a flight range of 425 nmi (489 mi; 787 km) using either automotive premium grade unleaded gasoline or 100LL avgas and a cruising flight speed of 93 kn (107 mph; 172 km/h). Equipment includes a Dynon Skyview glass panel avionics system, an airframe parachute, and an optional autopilot.[6]
On the road, it can drive up to 70 miles per hour (110 km/h)[7] with normal traffic. The Transition Production Prototype's folded dimensions of 6 ft 8 in (2.03 m) high, 7 ft 6 in (2.29 m) wide and 18 ft 9 in (5.72 m) long are designed to fit within a standard household garage. When operated as a car, the engine power take-off near the propeller engages a variable-diameter pulley CVT automatic transmission to send power to the trailing-suspension mounted rear wheels via half-shafts powering belt drives.[8] In flight, the engine drives a pusher propeller. The Transition has folding wings, pusher propeller and twin tail.
