I have a M440D. Daily I travel about 10 minutes to and from work, probably less than 5 miles each way. Light suburban traffic. Get high 30s.
When warmed up, city driving will be higher. Not heavy traffic, but just urban driving I will see low 40s.
Warmed up country driving I will easily get low-mid 50s.
Warmed up, steady Autobahn cruising has seen my mileage go into the 60s.

Last Summer I drove from Switzerland to the West of Scotland. Normally I catch a ferry (Previously Zeebrugge, now Rotterdam) but they were all fully booked. First time in 20 years that happened. So, bought a Eurotunnel ticket.
My idea was to see how far I could get, then get somewhere to stay the night.
I left at about 5am in Swiztzerland. I reset the trip meter. After about 30 minutes driving the range was indicated as 1100 kms.
When I arrived in England (early afternoon) I kept driving. In the evening I still felt OK, so pressed on. I arrived outside my Mum's house just after midnight.
Travellled 1022 miles door-to-door after 17 hours behind the wheel. Last 50 miles or so were enjoying the quiet, sweeping and undulating roads in the Galloway hills, at a pace of "skelping on".
MPG for the day was 56.4.
On the return trip I caught a ferry to Rotterdam. I drive on the Autobahn back at normal pace. Trip through Europe was 801kms and averaged 60.7 MPG. I had filled up at Ferrybridge services before Hull and still had a 1/4 of a tank remaining. Didn't re-tank for another few weeks.
None of those trips were done with any intention of hyper-miling. Just driving normally, torque surfing. Others will get much less economy I'm sure.
I also had an F32 330D S-drive, and a F32 335D. This M440D is night and day better on economy.
I've never used Eco mode. 99% in Comfort, occasionaly in Adaptive.
