# Stuttgart Aerospace

> Stuttgart Aerospace develops the Apollon VX, a road-legal hybrid eVTOL flying car combining urban driving with vertical takeoff and landing flight. Brand of Harontas GmbH, based in Waiblingen, Baden-Württemberg, Germany.

Stuttgart Aerospace is the consumer-facing brand of Harontas GmbH. The flagship development project is the Apollon VX, a hybrid-electric eVTOL designed for street-legal road operation and vertical takeoff and landing flight. The vehicle uses vectoring electric ducted fan propulsion, fly-by-wire flight control, distributed-propulsion safety architecture, and a ballistic parachute recovery system. The program is in concept and prototype development; no certification, commercial service, or production status is implied.
