Unlike the two-seater Transition, this new street-legal aircraft will seat four and run on electricity. That means the engine will recharge the batteries in the air or it could be plugged into a charging station on the ground. According to Terrafugia, the vehicle will also have electric ground drive and electric power assist for takeoff and landing.
Other cool features include retractable wings and the propellers that open from two motor pods. Initially the propellers point up for takeoff, then the motor pods tilt forward until the vehicle cruises and after that the propellers can fold in. The TF-X will have a non-stop flight range of at least 500 miles, and is expected to be able to automatically avoid other air traffic, bad weather, and restricted and tower-controlled airspace, according to the website, as well as implement an emergency auto-land at the nearest airport, if the operator became unresponsive. See more details in the Youtube video.
The vehicle will also have extensive safety features such as a parachute system to prevent it from crashing horribly should something go seriously wrong. Terrafugia indicated that learning how to safely operate the TF-X will take the average person five hours; a light-sport aircraft certification takes an additional 20 hours.
