GE9X engine for the 777X will be 10% more efficient than any twin aisle engine

The GE9X was selected to power the new Boeing 777X. The GE9X will be the most fuel-efficient engine GE has ever produced on a per-pounds-of-thrust basis, designed to achieve a 10% improved aircraft fuel burn versus the GE90-115B-powered 777-300ER and a 5% improved specific fuel consumption versus any twin-aisle engine at service entry. In addition, the engine will deliver an approximate 10-to-1 bypass ratio, a 60-to-1 overall pressure ratio and margin to Stage 5 noise limits.

The Boeing 787 Dreamliner has the GEnx engine. There are 320 engines in service.

The Boeing 777 has GE90 engine. There were more than 1,675 engines delivered.

The 777X is a jumbo jet killer.
