Terrafugia digitally renders TF-X.

Terrafugia claims to offer the future of transportation but that point still looks to be years away, if ever. The company's Transition flying car has shown itself able to fly, but the even more ambitious TF-X has been in development for years with promises of vertical takeoff and landing capabilities. So far, we've only seen renderings of the sci-fi craft take to the skies, and that hasn't changed with the latest video showing the newly updated outer mold line design.

The TF-X's revised shape features a sleeker, more car-like front end design and wraparound glass. Terrafugia is still making some absolutely monumental promises about the aircraft's capabilities, though. The four-seat plane uses an engine and two electric motors for propulsion. For take off, the wings fold out from the body, and propellers on swiveling nacelles let it take to the sky vertically like a V-22 Osprey. The props then fold back once airborne, and a ducted fan starts providing thrust, at least theoretically. Terrafugia claims the TF-X could cruise at 200 miles per hour and would offer a 500-mile range.
