VoltAero has officially revealed the production version of its Cassio 330 electric-hybrid aircraft, designed for sustainable regional transport. Presented ahead of the 2025 Paris Air Show at Le Bourget Airport, the updated configuration reflects the company’s ongoing collaboration with the European Union Aviation Safety Agency (EASA), aligning the aircraft’s design with the latest CS.23 certification standards for normal category aeroplanes.
The Cassio 330’s production version features a series-hybrid propulsion system, marking a key evolution from the original parallel-hybrid design. Two “pusher” Safran ENGINeUS™ electric motors are mounted on the rear fuselage, while a thermal engine acts as a range extender by recharging the batteries mid-flight. The aircraft operates in full-electric mode during taxi, take-off and initial climb, ensuring low-emission, low-noise performance.
This series-hybrid configuration has been adopted to reduce certification complexity and enhance reliability. Notably, the updated Cassio 330 introduces a T-tail in place of its original twin-boom structure, eliminating structural risks associated with propeller blade failure and increasing overall safety. The aircraft’s architecture is fully redundant, including dual battery strings and the ENGINeUS™ motors’ dual-channel stator windings, which enable continued operation in “half-engine-inoperative” scenarios.
The Cassio 330 maintains its flexible cabin layout, seating a pilot and up to five passengers. The aircraft is suited for various missions such as passenger transport, air ambulance services and cargo delivery. A large access door aids passenger boarding, particularly for those with reduced mobility on PSO (public service obligation) routes.
VoltAero will manufacture the Cassio 330 at its dedicated 2,400 m² facility in Saint Agnant, Nouvelle-Aquitaine, with a production capacity of up to 150 aircraft per year. This facility, inaugurated in late 2024, will serve as the central hub for Cassio-family aircraft production, supported by design, testing, and administrative operations. The company also plans to expand production to other strategic global markets.
