It must be all the start stop driving I do, the xc60 was frugal when I wasn’t doing 600 miles of A and B road driving every week, it was a fantastic car though and when my mileage dropped I regretted getting rid.
The XC40 I’m sure will improve, cold days and short town driving isn’t helping, I checked the trip computer today over 100miles and was avg 31mpg so hopefully a sign of things to come.
by the looks of it I may have a lead foot lol
