Meet The AltoVolo Sigma: A 1,608HP Personal eVTOL Jet
With 4x the range of its rivals and a footprint small enough to land on a driveway, the AltoVolo Sigma brings private aviation closer to daily life.
A new era in personal air travel has arrived with the launch of AltoVolo’s Sigma, a hybrid-electric VTOL aircraft that combines runway-free convenience with regional jet performance. Featuring 1,608 horsepower and a sleek, sculptural frame, Sigma is designed for high-speed, long-range, and ultra-quiet personal flight — potentially transforming both the eVTOL and helicopter markets.
Equipped with a patent-pending tilting jet propulsion system, the Sigma boasts a 500-mile range, a cruise speed of 220mph, and noise levels over 80% lower than traditional helicopters, making it ideal for use in residential areas. Its hybrid design draws on the burst power of electric batteries for take-off and liquid fuel for extended cruising, sidestepping the limitations of current all-electric VTOLs.
At just 4.8 meters wide and weighing 980 kg fully loaded with three passengers, the Sigma can land on driveways, rooftops, or yachts — no airport required. Safety is central to the design, which includes redundant jet operation and a ballistic parachute system.
“The Sigma is a statement of intent,” said Will Wood, AltoVolo’s founder and CEO. “We’re not just building a flying machine — we’re building the fastest point-to-point transport system, reimagining how we live and travel”.
AltoVolo is taking a lean-startup approach and aiming for rapid time-to-market, with full-scale demonstrator production underway after successful prototype tests. Its design and engineering have been validated by Dr. Richard E. Brown of Sophrodyne Aerospace, and its autonomous flight systems are supplied by Embention, known for powering Amazon Prime Air’s drones. Simulation support comes from Ansys, which also works with Formula 1 teams.

Unlike many competitors focused on short, intra-city flights, AltoVolo is targeting both urban and regional air mobility. The Sigma is pitched as a tool of independence for those who value time, privacy, and the freedom to travel on their own terms — no airport terminals, no congestion, no schedules.
Reservations for the launch edition open in July, with priority given to early qualifying customers.
