H600 Hybrid Engine

The Hybraero H600 Hybrid Engine is a clean sheet designed, lightweight, powerful, aviation engine

Whilst the general aviation market has moved forward in terms of new aircraft and construction techniques, the one area that has lagged behind is propulsion. Vintage designs of heavy, inefficient, Avgas based propositions have dominated the larger piston engine market for 40 years and more. The new Hybraero H600 hybrid engine is a 21st century propulsion system designed to sit within existing six cylinder engine footprints.

This innovative and exciting engine is being designed by world class motorsport engineering and advanced technology firm – Prodrive.
Based on their years of experience building high tech, lightweight and powerful engines for World Rally Championship programmes for the likes of Subaru and Mini, along with World Endurance sportscar racing engines for Aston Martin and many other race series around the world, Prodrive is going to deliver a new engine that combines a clean sheet design, internal combustion engine (ICE) capable of 300hp to be used in combination with twin electric motors able to deliver 300hp. The total output for this new hybrid engine is forecasted to be around 600hp when it begins testing next year.


One of the greatest problems for any single engine pilot around the world, is the fear of non-recoverable engine shut down. Once that engine is shut down, the aircraft will come down within its glideslope radius. Over 350 pilots lives have been saved with the introduction of ballistic parachute recovery systems, but the new Hybraero H600 hybrid engine, could allow pilots to switch to electric power for up to 10 minutes worth of flight time, enabling them to select a safe landing area without the need to resort to the safety parachute.

The other major bugbear for many pilots is the use of Avgas. The H600 engine will use JetA1 fuel as the primary fuel source, delivering large cost savings over equivalent Avgas based engines. With maximum take off power in excess of many turboprops, yet offering the efficiency of a modern piston engine design, this new engine is designed to be a direct replacement for many existing engines.

For those pilots looking to lower their carbon footprint even further, they will be able to run Biojet fuel as and when it is available, to help lower their emissions profile further.


The H600 engine has been designed for the Faradair BEHA aircraft, however there is interest already from other aircraft manufacturers for the engine.

Further details about the exact configuration and battery capabilities will be made available over the coming months, prior to the engine test runs. Faradair® Aerospace is handling all commercial and funding activities relating to the engine and further partners will be announced in due course. For all further information, please contact Faradair®
