What type of engine is the GE9X?
The general electric ge9x is a high-bypass turbofan developed by ge aerospace exclusively for the boeing 777x. It first ran on the ground in april 2016 and first flew on march 13, 2018; it powered the 777-9’s maiden flight in early 2020. The ge9x engine from general electric (ge) represents the latest generation of propulsion systems for long-haul airliners, specifically the new boeing 777x widebody aircraft. Based on the tried-and-true architecture of its predecessors, the ge90 and genx, the ge9x features the latest materials and technologies.At 174 inches across (nacelle or casing included), the GE9X is wider than a Boeing 737 fuselage (148 inches)—and it’s about to lift the 777X into commercial service.
How fuel-efficient is the GE9X?
GE9X: Powering the Boeing 777X It also sets new standards for efficiency: compared to its predecessor, the GE90-115B, it should achieve a 10 percent reduction in fuel consumption—and its CO2, NOx, and noise emissions will be significantly lower as well. Beyond internal disruptions, the 777X has had its fair share of technical issues that have had to be resolved before progressing in the certification process. Flight testing has been paused numerous times due to GE9X engine issues, the sole powerplant for the 777X, as well as for other reasons.
Which is more powerful, GE90 or GE9X?
The GE9X is the most powerful aircraft engine in history and the quietest GE engine ever produced (pounds of thrust per decibel). The engine will bring up to 10% specific fuel consumption improvement compared to the GE90-115B. The GE Aerospace GE9X is the world’s most powerful commercial jet engine. Although it is yet to enter commercial service with the Boeing 777X, it already holds the Guinness World Record for maximum thrust.The GE9X is the largest and most powerful commercial aircraft engine ever built, incorporating advanced technologies that enable more efficient, quieter flight with fewer emissions.Long range: 7,370 nautical miles nonstop ✅ Power: GE90-115B engines — still the most powerful ever on a commercial jet ✅ Efficiency: $44 per seat hour, compared to $50 on the A380 and $90 on the 747-400 ✅ Over 830 deliveries, making it the best-selling 777 variant It killed off fuel-thirsty giants like the 747 and .In 2025, the aircraft with the world’s most powerful commercial engines is the Boeing 777X, powered exclusively by the GE Aerospace GE9X. It is the largest turbofan ever built, the current Guinness World Record holder for thrust, and the technological centerpiece of Boeing’s next-generation flagship.It was the largest jet engine, until being surpassed in January 2020 by its successor, the 110,000 lbf (490 kN) GE9X, which has a larger fan diameter by 6 inches (15 cm).
