Is GE9X more powerful than GE90?
Technical comparison. The GE9X is the largest commercial aircraft engine with a fan diameter (134 inches / 340 cm) nearly equal to the fuselage width of the Boeing 737. The GE9X can produce 134,300 bf (pound-force) of thrust and is 5% more powerful than GE90. GE9X Engine. 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.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.Meet the World’s Most Expensive Jet Engine. Boeing 777X x GE9X. This isn’t just power—it’s precision engineering at $41 MILLION each.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 .However, Airbus does beat Boeing on range. The A350-900ULR flies nearly 9,700 nautical miles, far beyond the 777-9’s listed 7,285. While Boeing’s 777X family is physically larger, Airbus wins on fuel efficiency and lightweight design.
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. At takeoff speed and full thrust you get around 55,000 HP for GE90-115B, while your thrust actually decreases the faster you go. The actual fan shaft will transfer around 30,000 HP from the LP turbine to the Fan, internal to the engine.
Why is the GE9X so big?
The GE9X’s enormous size reflects Boeing’s needs for a high-capacity, long-range aircraft that meets 21st-century fuel and emissions standards. It’s about engineering a powerful engine that cruises efficiently at high altitudes with minimal environmental impact. 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.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.
Is the GE9X bigger than a 737?
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. The A380 is bigger in all dimensions than the 777X and has a higher MTOW and capacity. While the 777X is slightly longer than a 747–8 it has a smaller capacity and MTOW. When the now limited production run of the 747–8 and 747–8f planes end the 777X will be Boeing’s largest plane in production.The smaller 777-8 also measures longer and taller than the A350-900, though the margin is thinner. In terms of cabin width, Boeing wins again. The 777X series has an internal width of 19. A350’s 18.Surprisingly, the 777-300ER is longer and wider than the 747-400, measuring 73. However, the 747-400 has a taller profile at 19.As of February 2026, a total of 65 Boeing 747 aircraft, or just above 4% of the total number of 747 built, have been involved in accidents and incidents resulting in a hull loss, meaning that the aircraft was either destroyed or damaged beyond economical repair since the type was first flown commercially in 1970.It was designed this way to have much greater passenger capacity, accommodating up to 500 passengers. Had it been built, it would have been a competitor to the A380, which was slated for release in the 2000s. The project was canceled because Boeing began focusing on the 747-8.
