Study Finds GEnx-Powered Boeing 787-10 Leads Widebody Fuel Efficiency Among 14 Competitors

An Aircraft Commerce study comparing 14 widebody aircraft-engine combinations across five routes found that the GEnx-powered Boeing 787-10 produces the lowest fuel burn per available seat mile of any widebody configuration currently in service. The finding ranked the 787-10/GEnx ahead of the same aircraft with Trent 1000 engines, ahead of both A350 variants, and ahead of every older widebody type including the 777-200ER, 777-300ER, and 747-400.
