GE Aviation's 777X engines have the largest fan ever produced for a commercial aircraft. They have been specially developed for the 777X.
The wings of a 777-9 clearly surpass those of a conventional 777-300. So that the 777-9 can be parked at the same gates, the last 3.5 meters of the wings are simply folded up.
