A quiet revolution in aviation is about to take flight. AltoVolo’s launch vehicle, Sigma, is set to take on both the electric vertical take-off and landing (eVTOL) space and the global helicopter market. The company’s founding members have identified a less capital-intensive development path and a quicker route to profitability in the advanced air mobility (AAM) sector. AltoVolo is one to watch in 2025 having engineered a vehicle 80% quieter than helicopters and with 4x better range than leading eVTOL players.
- Featuring a hybrid-electric tilting jet propulsion system for improved efficiency and reduced noise.
- Resulting in a 500-mile range and cruise speed of 220mph.
- Over 80% quieter than helicopters making it suitable for use in residential areas.
- Safe stable flight is possible following failure of one jet, it also has a ballistic parachute.
- Compact size and light weight design, just 4.8m wide and 980kg with 3 passengers on board.

A vision from the future has arrived
“The Sigma is a statement of intent, reimagining the way we live and travel on our planet. We are building the fastest point to point transport solution and have already achieved significant breakthroughs to make this happen”. Says founder and CEO, Will Wood. The Sigma’s cutting-edge design and engineering has been validated by Dr Richard E Brown of Sophrodyne Aerospace, a leading authority on aerodynamics. AltoVolo has also received support from Ansys who provide simulation tools to f1 teams. Scale prototype flight testing is complete, and quick progress is being made towards production of a full-scale demonstrator. Autonomous flight systems are provided by Embention, the Spanish firm who supply certified flight controllers to Amazon Prime Air.
This private jet doesn’t need a runway
The Sigma does not resemble any eVTOL currently on the market. It is ultra-compact, sharper, and designed with precision more akin to a sculptural automotive icon than a prototype aircraft. Under its clean silhouette lies engineering that redefines the limits of vertical flight. AltoVolo has combined a patent pending tilting electric jet design and integrated aerodynamics, to leverage the high burst capability of batteries for vertical take-off and landing (VTOL), and the energy density of liquid fuel for long range flight. Its footprint is small enough to land on driveways, rooftops, or yachts. At its heart, AltoVolo’s mission is to make flight a part of everyday life. No terminals. No timetables. No congestion. No dependence on public infrastructure or waiting for urban planning policies to catch up.
Building the future of personal transport
Qualifying customers will be invited to join the waiting list for a launch edition Sigma vehicle in early July. AltoVolo is delivering what it has dubbed a “vertical hybrid jet” that gives its owner time, independence, and reach. Creating opportunities far beyond the short-haul city missions most eVTOLs are targeting. The Sigma is meant for regional air mobility (RAM) as well as urban air mobility (UAM). It’s built for those who prefer to move when they decide, to where they choose, in the fastest, safest and most efficient way. AltoVolo is a personal aircraft, designed for people who understand the art of living.
