The 850 to 1,600 hp (630 to 1,190 kW) engine aims for 20% better efficiency than its competition thanks to a 16:1 overall pressure ratio, variable stator vanes, cooled turbine blades, 3D printed parts and FADEC.

[4] In 2016, the gearbox, power turbine and combustor were to be made in Turin, the rotating components were to be supplied from Warsaw and the final assembly line was planned at Walter Engines in Prague.

[5] At the time, major components were split between GE-owned facilities in Poland and Italy, both belonging to Avio Aero.

[9] In October 2017, GE received 85% of the parts, on track to deliver the first test engine by the end of the year.

[10] At this time, the axial-centrifugal compressor vehicle - stator, rotor and cold-section assemblies - was tested in Munich to validate its efficiency, performance and operability.

After most of the component tested and the engine run, GE Aviation maintains its performance objectives and hope to exceed them.

It was developed over two years by 400 GE designers, engineers and materials experts in the Czech Republic, Italy, Germany, Poland, the U.S. and elsewhere.

New icing tests requirements pushed back the first engine delivery to 2020, and Beechcraft Denali first flight even further.

[19] One turboprop was fitted to a Beechcraft King Air 350 in Berlin which completed some taxi tests, to achieve maiden flight in the coming months and certification by end-2022.

[23] It will compete with the Pratt & Whitney Canada PT6, produced at 51,000 units and leading the small turboprop market for 50 years, adding to the sub 850 horsepower (630 kW) General Electric H80.

It has been selected to power the new Beechcraft Denali single engine turboprop aircraft, seating up to 12 passengers at over 280 knots (520 km/h) for 1,500 nautical miles (2,800 km).

GE plans to invest up to $1 billion in the project, including $400 million for a manufacturing center in Europe.

Its 16:1 overall pressure ratio allow a 20% lower fuel burn and 10% higher cruise power than same size class competition with a 4000–6000 hour mean time between overhauls (MTBO).

GE proposed channelling to the engine inlet hot oil from an accessory gearbox sump to avoid growing ice and will test this in a Canadian cold weather facility in summer 2018.
