UK-based Vertical Aerospace has announced the development of a new hybrid-electric variant of its VX4 eVTOL, targeting mission profiles that demand greater range and payload capacity.
Designed for defense, critical logistics, and air ambulance services, the new aircraft will be capable of flying up to 1,000 miles (1,600 km) – ten times the range of the fully electric aircraft.
The hybrid propulsion system has been in development for 18 months at Vertical’s Energy Centre and will be integrated into one of the company’s full-scale VX4 prototypes, with flight testing expected in Q2 2026.
Key features of the hybrid-electric VX4 include a payload capacity of up to 1,100 kg, low noise and heat signatures suitable for sensitive missions, and flexible operation modes—crewed, remotely piloted, or fully autonomous—thanks to advanced flight control integration with Honeywell.
Vertical sees the aircraft serving roles that current eVTOLs cannot fulfill, including military transport, border patrol, emergency medevac, and long-distance cargo operations.
“The demand for long-range, high-payload, quiet aircraft is growing rapidly—especially across defense and critical logistics,” said Stuart Simpson, CEO of Vertical Aerospace.
The hybrid VX4 is built upon Vertical’s proprietary battery system, developed to meet rigorous safety standards from EASA and the UK CAA. Bench testing has already validated its hybrid-electric architecture, including real-time integration between the power unit and control systems.
The aircraft’s large and flexible airframe allows for seamless hybrid integration without major redesign, offering scalability and mission adaptability not easily matched by smaller eVTOL platforms.
