VoltAero will be making a “high-powered” U.S. debut at the upcoming EAA AirVenture, exhibiting its new HPU 210 hybrid power unit for the first time on American soil, and opening reservations for production slots of this innovative propulsion system tailored for homebuilt, kit-built and light aircraft.
The HPU 210 is a game-changer for general aviation: combining a high-performance 150-kW Kawasaki Ninja H2 SX-derived piston engine with a 60-kW electric motor, this hybrid power unit delivers an unprecedented 40 percent boost in takeoff and climb power – all controlled through a single throttle. The system introduces VoltAero’s patented, flight-proven hybrid-electric technology to a new category of aircraft, delivering enhanced safety, efficiency and performance.
The HPU 210: Validated Hybrid Technology for a New Class of Aircraft
In developing the HPU 210, VoltAero has leveraged its experience from the more than 185 flight hours and 25,000 kilometres logged with the electric-hybrid Cassio S demonstrator airplane.
The HPU 210 offers:
- Electric boost – to allow 50% reduction of a take-off distance
- Fuel flexibility (AVGAS, biofuel, unleaded auto fuel);
- Low cruise fuel consumption (as little as 38 litres/hr.);
- 1,500-hour estimated TBO (time between overhaul); and
- Seamless integration into existing airframes.
The HPU 210 will be delivered as a complete, turnkey package, including thermal engine, electric motor, gearbox and electronic control unit. Initial customer deliveries are targeted for late 2026 from VoltAero’s production site and headquarters in Rochefort, France.
