Sigma Takes Flight: A Sleek Leap Toward the Skies

London startup AltoVolo just unveiled the Sigma, a hybrid-electric eVTOL that looks part spacecraft, part sculpture. With tilting jet propulsion, it uses batteries for lift-off, liquid fuel for range, and ambition for everything in between.

Projected to fly 510 miles, cruise at 220 mph, and hit 290 mph at full tilt, it does all this while weighing just 2,160 lbs—with three passengers on board. At only 15.7 feet wide, it’s compact, clean, and seriously fast.

A scaled prototype has already flown; now comes the full-size demonstrator. No production date yet, but Sigma’s message is clear: the sky isn’t the limit, it’s the beginning.
