The final time we heard from the UK’s AltoVolo, it solely had renders of its grand vision for a sportscar equivalent of an eVTOL to indicate off. That was precisely a yr in the past – and it is now received a working prototype taking to the skies.
The London-based agency has constructed and flown a 1:4 scale prototype of its Sigma plane, which eager observers will word appears to be like drastically totally different from the earlier idea we noticed in 2025.
It is sticking with the earlier focused vary of 500 miles (804 km) and prime velocity of 220 mph (354 km/h). That is quicker than the five-seater Joby Aviation flew between JFK Airport and New York Metropolis’s heliport community (200 mph or 322 km/h) as a part of an air taxi demo last week. If it may hit these figures, the Sigma will probably be among the many quickest eVTOLs you’ll board within the subsequent couple of years.
AltoVolo Flies Sigma Prototype
You’ll be able to see the scaled-down Sigma prototype within the air within the brief video clip above. AltoVolo claims it is efficiently accomplished the preliminary design evaluation in addition to testing of this early model, forward of full sort certification.

Look intently, and you will discover the design has advanced to a two-seater configuration, down from three. The corporate says this permits it to be flown by anybody with a Sport Pilot certificates and solely 25 hours of coaching, in the course of the day and with truthful climate circumstances. This expands the potential use circumstances for this automobile – and I think about it will increase room on your baggage.

The opposite large distinction from the earlier renders is you’ve got received open rotors for takeoff and cruising, as a substitute of closed electrical ducted followers. AltoVolo says it discovered this change allowed for double the hover time, faster propeller loading, and weight financial savings – and it is developed its personal fastened pitch propeller that is higher suited to this automobile than alternate options obtainable off the shelf.

The subsequent step is to provide the full-scale Sigma demonstrator, which can actually check the design and engineering that is going into this automobile. AltoVolo hasn’t revealed a timeframe for this, however we’ve seen it take some other companies a year tor more to get to that stage.

It’s going to then should ace transition flight exams, cross aviation certification necessities, and get its manufacturing pipeline so as earlier than it may start rolling this out to high-flying clients who need the quickest brief experience within the sky.
