I have now done 14000 miles in 12 months of owning my 2.0 diesel 4x4 cross auto. On my frequent longer motorway/A road runs, 47-49 is the norm, on short runs 41-43 is typical. I use auto mode all the time, and Sport purely for overtaking. Mpg in this car is very sensitive to the type of journey,unlike my Mini Countryman All4 CooperD, which achieved the same figures consistently. Figure in the high 20's sound very disappointing. I am in Northern Ireland/Donegal, where there is little congestion, but plenty of hills!
