What VoltAero does
VoltAero SAS is a French aerospace company founded in 2018 by Jean Botti and a team of electric-aviation veterans from Airbus (with prior involvement in the Cri-Cri and E-Fan programs). The company designs and is preparing to manufacture the Cassio family of electric-hybrid aircraft — the 4–5 seat Cassio 330 (330 kW), the 6-seat Cassio 480 (480 kW), and the 10–12 seat Cassio 600 (600 kW) — built around a proprietary series-hybrid propulsion architecture using dual aft-fuselage-mounted Safran ENGINeUS smart electric motors, dual independent battery strings, and a Kawasaki-derived thermal engine used as a range extender. The architecture, validated on the Cassio S flying testbed through 185+ flight hours and approximately 25,000 km, is engineered to meet EASA CS.23 certification and supports all-electric operation for taxi, takeoff, and flights under 150 km, with the thermal engine as a fail-safe backup. VoltAero's revenue model centers on aircraft sales (Cassio 330 first to market), the recently introduced HPU 210 hybrid powertrain for the homebuilt/kit-built market, licensing/regional manufacturing rights (e.g., the SEDC Energy-ACI Groupe joint venture for Asia-Pacific), and downstream support, training, and MRO services tied to regional channel partners in France, North America (AltiSky), and Malaysia. Headquartered at a 2,400 sqm purpose-built facility at Rochefort Airport (Saint Agnant, France) sized for 150 aircraft per year at full rate, with an administrative office in Paris, VoltAero is pursuing EASA certification with deliveries targeted for late 2026 and was acquired by fellow French low-carbon aviation company AURA AERO in June 2026.

VoltAero product offering
Product offeringCore offering
VoltAero designs, manufactures, and sells the Cassio family of electric-hybrid aircraft (Cassio 330, 480, and 600) for regional commercial transportation, charter, utility (cargo/medevac), and pilot training applications. The company also sells the HPU 210, a standalone hybrid power unit adapted from Cassio technology for the homebuilt, kit-built, and light aircraft market. All products use a proprietary series-hybrid propulsion architecture combining Safran ENGINeUS electric motors with a Kawasaki-derived thermal engine acting as a range extender.
Product overview
VoltAero develops a family of electric-hybrid aircraft called Cassio for safe, quiet, efficient, and eco-friendly regional transportation. The product lineup consists of three aircraft variants: the Cassio 330 (4-5 seats, 330 kW), Cassio 480 (6 seats, 480 kW), and Cassio 600 (10-12 seats, 600 kW). All Cassio aircraft use a proprietary series-hybrid propulsion architecture with Safran ENGINeUS electric motors providing all-electric power for taxi, takeoff, and shorter flights, while a Kawasaki internal combustion engine serves as a range extender. The product portfolio also includes the HPU 210 hybrid power unit — a standalone propulsion system adapted from the Cassio technology for homebuilt, kit-built, and light aircraft — and a universal mobile charger for aircraft ground operations. The Cassio S testbed demonstrator has validated the hybrid propulsion technology through extensive flight testing.

VoltAero competitors and assessment
Company assessmentDirect peers
- magniX: Electric-propulsion system supplier for aircraft, including the Eviation Alice and various seaplane retrofits. Comparable to the HPU 210 portion of VoltAero's business as a standalone electric/hybrid powertrain provider selling into both OEM and retrofit markets.
- Eviation Aircraft: Developer of the Alice, a nine-seat all-electric commuter aircraft aimed at regional and charter operators. Directly comparable to VoltAero in target customer base (regional airlines, charter), propulsion philosophy (electric flight), and certification stage.
- AURA AERO: French aircraft manufacturer of the Integral E electric trainer and ERA hybrid-electric regional aircraft, and VoltAero's parent company post-June 2026. Closely comparable product portfolio (electric trainers, hybrid regional) and now the controlling entity for VoltAero's roadmap.
- Pipistrel (Textron eAviation): Slovenian maker of the Velis Electro, the first type-certified all-electric airplane, plus hybrid concepts. Directly comparable as an electric-light-aircraft OEM with certified products, training-market focus, and parallel powertrain-development roadmap.
- ZeroAvia: UK/US hydrogen-electric propulsion developer for 9–20 seat regional aircraft, with multiple airline partnerships and orders. Competes with VoltAero for the same regional operator decarbonization mandate but takes a hydrogen-fuel-cell path rather than series-hybrid.
- Heart Aerospace: Swedish developer of the ES-30, a hybrid-electric 30-seat regional airliner targeting the same short-haul, regional-route decarbonization use case as VoltAero's Cassio family. Both companies pursue EASA certification of hybrid-electric propulsion for commercial regional operators.
- Bye Aerospace: US developer of the eFlyer family of two- and four-seat all-electric training aircraft. Overlaps with VoltAero on the flight-training academy customer segment and the underlying propulsion-as-differentiator thesis.
Broad incumbents
- Rolls-Royce: UK propulsion major with active electrical and hybrid-electric aviation programs (Spirit of Innovation) and a broad installed base in regional turboprops. Relevant incumbent on the propulsion-supplier and certification-stakeholder axis for hybrid-electric regional flight.
- Airbus: European commercial-aircraft OEM where VoltAero's founders led the Cri-Cri and E-Fan electric programs. Airbus's ZEROe hydrogen efforts and broader sustainability investments make it a broad incumbent shaping the regulatory and competitive environment VoltAero operates in.
- Daher: French manufacturer of the TBM and Kodiak single-engine aircraft, exploring hybrid-electric derivatives for general and regional aviation. Comparable as a French incumbent in the same single-engine turboprop segment VoltAero's Cassio family targets.
