6. Ehang 184
Ehang is an Electric drone capable of vertical takeoff and landing and has a top speed of 80 mph. It will only stay airborne and fly for 25 minutes. The battery technology has a ways to go to enable longer flight time. But the company says its current range of 25 miles is enough to establish a viable air taxi service in most cities. The Ehang is designed to carry one passenger and has eight propellers on four arms.
