The Terrafugia TF-X is an autonomous flying car under development by Boston-based Terrafugia. The TF-X seats four passengers and uses an engine combined with two electric motors for propulsion. Unlike the previously proposed Transition, the TF-X is capable of vertical take-off and landing by extending its retractable wings attached with pusher propellers, while aerial thrust is provided by a ducted fan at the rear. It will be able to fit in a single car garage.
