At launch, Boeing targeted the 787 with 20% less fuel burn than replaced aircraft like the Boeing 767, carrying 200 to 300 passengers on point-to-point routes up to 8,500 nautical miles [nmi] (15,700 km; 9,800 mi), a shift from hub-and-spoke travel. The twinjet is powered by General Electric GEnx or Rolls-Royce Trent 1000 high-bypass turbofans.
