AviationGeeks.com - Boeing´s 777-9X comes into focus with a massive CFRP wing

Building on its 777-300ER, Boeing is evaluating its next moves in the 300 to 415-seat market, with its conceptual 777-8X/9X, powered by a smaller GE90-derived engine, composite wing, a possible fuselage stretch and shrink and higher economy seating capacity, marking what is likely to become the second major incremental evolution of the 777 family, 15% better than today's aircraft, say those familiar with the studies.

The options to Boeing now coming into focus look to grow the 213ft metallic wingspan of the long-range twin to as much as 234ft (71.3m) with a carbon fiber design, 10ft (3.05m) wider than the 747-8. Initial estimates being evaluated by Boeing point to a lower maximum takeoff weight of around 753,000lbs (342t) for the 777-9X, which would anchor the family and preserving or growing the payload range capability of just under 8,000nm (14,800km) for today's aircraft.
