AltoVolo’s flying vehicle promises to reach 827 km with less noise than a helicopter (Instagram @altovolo.inc)
British startup AltoVolo has revealed details of the Sigma, its first hybrid-electric eVTOL model.
Designed to carry up to three people, the vehicle promises a range of up to 827 km in hybrid mode, with a cruising speed of 354 km/h and 80% less noise than a helicopter.
The idea is to offer an alternative to private helicopters operating in residential areas, rather than compete with air taxi services. Although still under development, the prototype has already undergone flight testing, and full-scale production is underway.
The Sigma stands out for its ultracompact design and engineering focused on efficiency and safety. With a maximum takeoff weight of 980 kg, it offers 15 minutes of hover flight time and can carry up to 270 kg. The aircraft features a triple-redundant control system, thrust vector stability, and a ballistic parachute deployable at 15 meters.
The design was validated by an expert from Sophrodyne Aerospace, while the autonomous flight systems come from Spain’s Embention, a partner of Amazon Prime Air.
In addition to being quiet, the Sigma can land in tight spaces such as rooftops, sidewalks, and even yachts, without relying on public infrastructure. According to AltoVolo, the project combines the high performance of batteries for vertical takeoffs and landings with the energy density of liquid fuels for long-range flights.
The startup aims to make flying part of daily urban life with a model that it claims breaks away from everything previously known about vertical aircraft.
