787 Fuel Efficency?

Thu Mar 12, 2020 8:33 am

Lots of technical details and photos highlighting the development and construction of the 787. In the book it mentioned Boeing's goal of a 20% improvement in fuel burn over the prior generation 763. As I recall, when ANA introduced the 788 on their NRT-CDG route they claimed a 21% fuel burn improvement versus their 763 ER.

The book states 8% of the fuel burn improvement was due to better engine performance and 3% improvement was due to use of composites. The remaining 9% improvement is not specifically mentioned.

My question is this: When I look at fuel burn numbers between a 788 and a A330-200 which are virtually identical in size (floor space is within 2-3%), I have seen claims that the 788 is somewhere between 12%-17% more fuel efficient. That seems a little high to me as the A330 CEO is obviously newer tech than the 767.

Does anyone have any thoughts about this. How efficient is the 787 versus the A 330 CEO family?


Thanks.

Airbus claims hat their own neo is something like 14% better than the ceo, with 11% from the engines. 12-17% depending on the config doesn't seem too far off, and still gives the 332 a decent 5ish percent margin over the 763.

The 763ER is actually cheaper, per seat, than the A330. The issue is cargo and, now, range.
