This isn't particularly specific to the 2-series, it applies to anything really. (This car is a 218d auto) I am not really concerned anymore with power and speed, more a smooth quiet ride with efficiency nowadays, this is what put BMW on the final shortlist this time round having never owned one before. While I am trying not to get obsessed with economy, the amazing technology on such a modern car makes it quite interesting to see what can be achieved. The car is also the most powerful that I've owned even though it is only 150ps. This trip computer screen was one way non-stop journey to Northumberland just before the recent lockdown, comprised of Motorway/A1 then twenty miles of single carriageway road. I was driving normally but keeping to 60mph max with the odd burst of speed up to 70 to occasionally pass large vehicles safely. The return journey was similar, so didn't take a pic of that but remembered to look at the 'bonus miles' back at home after a couple of local errands which may have reduced the figure slightly. (I usually leave the display on the cluster on temperature) Just over half a tank for 400 miles seems to be good too, I think the low fuel warning came on at about 650 miles after mainly suburban running on the remainder of the tankful. It is only a 50 litre fuel tank. The 'onboard' computer shows about 51mpg overall since October when we got it, about 2500 miles.
