Vertical Aerospace Announces Long-Range Hybrid VX4 Air-Taxi Program

On May 12, 2025, Vertical Aerospace announced it is developing a hybrid-electric variant of its VX4 air-taxi, aiming to dramatically expand range and payload capabilities for defense, logistics, and broader commercial markets. This marks a significant step for the electric vertical take-off and landing (EVTOL) sector, as reported by Reuters and official company statements.

Hybrid Technology Boosts Range and Payload

The new VX4 hybrid-electric variant is targeted to achieve a range of up to 1,000 miles-a tenfold increase over the all-electric VX4-and can carry payloads of up to 1,100 kilograms (2,425 pounds). Vertical Aerospace’s second-generation hybrid-propulsion system, developed at its Energy Centre over the past 18 months, will be integrated into a full-scale VX4 prototype. Flight testing is scheduled to begin in the second quarter of 2026, with certification targeted for 2028.

This technological leap addresses a key limitation of fully electric eVTOLs: range. While electric models excel in short urban hops, the hybrid system enables longer missions, such as transporting critical supplies or supporting defense operations. The VX4’s design retains its vertical take-off and landing capabilities, ensuring flexibility for operations in remote or congested areas.

Expanding Applications for eVTOLs

The hybrid VX4 is poised to tap into growing demand beyond Urban Air Mobility. “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, during the announcement. This variant opens doors for applications such as military resupply missions, disaster relief, and remote cargo delivery, where extended range and heavier payloads are essential.

Vertical’s move comes amid a competitive race among air-taxi startups to secure regulatory approvals and commercial contracts. The company recently expanded its partnership with Honeywell to certify key systems for the VX4, a step that strengthens its path toward operational deployment.

Industry Trends and Future Outlook

The eVTOL industry is evolving rapidly, with companies like Vertical Aerospace diversifying their portfolios to meet varied market needs. The hybrid approach could bridge the gap between current battery limitations and the demands of long-range missions, potentially accelerating adoption in sectors like defense, where reliability and range are non-negotiable.

Economically, the hybrid VX4 could reduce operational costs for long-distance missions compared to traditional helicopters, thanks to its electric components. However, regulatory hurdles remain a challenge. Certifying a hybrid eVTOL for commercial use involves rigorous safety and environmental standards, particularly in the defense sector, where airworthiness requirements are stringent.

Vertical Aerospace’s stock rose over 6% following the announcement, reflecting investor confidence in its strategy. As the eVTOL market matures, innovations like the hybrid VX4 could redefine aerial logistics and urban transport, offering a quieter, more sustainable alternative to conventional aircraft.
