London-based startup AltoVolo is aiming high with its entry in the developing eVTOL space. It plans to offer a powerful personal hybrid-electric aircraft that will seat three people, deliver 510 miles (821 km) of range, and hit cruise speeds up of to 220 mph (354 km/h) – all while making 80% less noise than a helicopter.

    More efficient at helicopter things, but this is a VTOL which i think swings it back into its favor for standard flight.

    I’m not an expert though. lol

      Vtol just includes vertical takeoff and landing, which helicopters do. The motors for eVTOL can be smaller than engines, so maybe you save some weight avoiding the collective? The tail rotor is also just loss, so I would think 2 rotor would be the most efficient. But I think these companies go with more for additional residency?
