Swiss aviation startup Sirius Aviation AG, has released details of its Sirius Jet, and aims to make it the world's first hydrogen-powered Vertical Take-Off and Landing (VTOL) aircraft; crafted and designed in collaboration with BMW's Designworks and Sauber Group.

The Sirius Jet is a high-performance, zero-emission aircraft, propelled by a hydrogen-electric propulsion system. Leveraging jet aerodynamics with aeroplane and helicopter versatility, it will achieve extended flight distances, impressive speeds, and high altitudes at near-silent levels.

The company has targeted 2025 for the Sirius Jet to take flight in two versions: Sirius Business Jet, tailored to private jet needs, and Sirius Millennium Jet, intended for commercial aviation.

The Sirius Business Jet will have 1,150-mile flight range, cruise speed of 323 mph, altitude capability of 30,000 feet, ultra-quiet noise levels of 60dBa, and accommodate three passengers. The Millenium Jet will have a shorter 650-mile flight range, but accommodate up to five passengers.

Sirius Aviation is working with BMW Group's DesignWorks, Sauber Group, renowned for its Formula 1 excellence, along with Alfleth Engineering AG, and ALD Group. This collaboration sets a pioneering benchmark for sustainable, efficient and high-performance aviation, it says.
