For comparison my 2.0D SDrive has done 15K km's and now sits on 56MPG highway 110kph flat road (no hills) and "hoon" driving around town at worst 39MPG.
You use imperial gallons down there, right?
If so, converted to US gallons, that would be 47 mpg hwy and 32 mpg city.
Which seems ok for a 2 l diesel in a midsized car.
Unfortunately, we don't get the diesel models in the US, so a direct comparison is difficult.
