The block and cylinder heads of the 4-inline cylinder, 2.1-litre displacement diesel engine is made in aluminum. In option, the engine can use JP8 or Jet A1 fuel. Weighing 165kg (dry), this water-cooled, Common Rail turbocharged engine develops 170 hp at 2,300 rpm. It burns less than 210g/kWh. The gearbox is pusher and puller compatible. The engine remains efficient up to a critical altitude of at least 20,000 ft but remains operational at 40,000 ft.

The advantages of this engine are a high power/weight ratio, its power capability at high altitude, its low fuel consumption, and its compact design.
