A London-based startup called AltoVolo is making bold claims in the world of personal air travel with its hybrid-electric flying vehicle that could revolutionize how the wealthy get around.

What Makes This Flying Machine Special?

AltoVolo's "Sigma" aircraft isn't just another concept in the crowded electric vertical takeoff and landing (eVTOL) market. This three-seater flying vehicle promises some truly impressive specs:

• A whopping 510 miles (821 km) of range
• Cruise speeds up to 220 mph (354 km/h)
• 80% quieter operation than traditional helicopters
• Just 15.7 feet wide (about the same as a double garage door)
• Incredibly lightweight at 2,160 pounds (980 kg) with three passengers

If these numbers prove accurate, the Sigma would outperform most competitors in the emerging eVTOL space by significant margins.

How Does It Work?

The secret to Sigma's impressive performance lies in its hybrid approach. AltoVolo has developed a patent-pending tilting electric jet design that uses batteries for the power-intensive takeoff and landing phases, then switches to liquid fuel for efficient long-distance cruising.

This clever engineering solution addresses one of the biggest challenges in electric aviation—battery limitations—while maintaining the benefits of vertical takeoff and landing.

The aircraft also features redundant systems, with AltoVolo claiming it can continue flying even if one jet fails.

Who Is This For?

Unlike companies such as Archer Aviation and Joby, which are developing air taxis for urban transportation networks, AltoVolo is targeting wealthy individuals who currently use private helicopters.

The Sigma is designed for "multimillionaires who have places to be," allowing them to travel directly between rooftops, yachts, and remote locations without the noise pollution associated with helicopter travel.

What's Next?

While the concept images look impressive, AltoVolo currently only has 3D renders to show. However, the company claims it has completed prototype testing and is preparing to build a full-scale demonstrator.

For those interested in being early adopters, AltoVolo plans to open a waitlist this July for its "vertical hybrid jet." No price has been announced yet, but given the target market, expect it to be in the luxury range.

The eVTOL industry has seen many ambitious projects struggle to move from concept to reality, so time will tell if AltoVolo can deliver on its impressive promises. If successful, however, the Sigma could represent a significant leap forward in personal aviation technology.
