The SureFly is a two-seat hybrid eVTOL vehicle designed by American truck-maker Workhorse Group.

Design[edit]

The 70 mph (110 km/h) hybrid electric has a 200-hp gasoline generator giving up to 70 mi (110 km) range over 1 hour.[1] It has four propeller arms, each with two electric contra-rotating propellers powered by a gas turbine or piston engine generator along a battery pack. Targeting a price of $200,000, it can lift a 400 lb (180 kg) payload and include a ballistic parachute.[2]

Development[edit]

After hundreds of tethered flights testing noise, battery and flight controls, it made a free first flight in spring 2018, reaching four feet during 10 seconds. Flight tests will expand the flight envelope while FAA type certification advances. Workhorse intends to spin off SureFly into a separate company, valuing it $33 million.[2] Workhorse should begin delivering SureFly delivery drones by 2020.[3]
