For reference I'm getting about 17 mpg in my 2019 750ix with 85% city driving.

Similar results here for a 2020 750ix. On a recent 170 mile (85 mi round trip), mostly but not all highway), the mpg was about 26. I had an inline 6 735 some years ago, and felt the engine was okay, but just barely. The 750 loafs at 80 mph.
