Hi. I'm new around here. Have had my Cooper D manual 2WD for a few weeks now, which I bought as an ex-demo with 4500 on the clock. It has now done approaching 6000, and I'm averaging around 49 mpg. I had expected much better. My previous was a Golf mk6 2.0 TDi, and I was averaging somewhere north of 65 mpg (depending largely on time of year), even better than the published stats (and yes, I'm confident that my figures are accurate).
I'm really disappointed with the consumption on the Countryman. I do around 25000 miles per year, and so economy is very important to me. I had hoped to get somewhere reasonably close to the claimed 64 mpg. I reckon the 1.6 engine is having to work too hard at motorway speeds, or on on the slightest uphill gradients. Cruising at 70 on a flat motorway, my Countryman will be doing around 45 mpg at best, whereas the 2.0 Golf would have been doing high 60s in the same conditions i.e. not having to work nearly as hard as the Mini's engine.
Anyway, other that the consumption, I'm happy with most other aspects of the car. But I just hope the MPG improves further as I put more miles on the engine, otherwise I may well have to sell the car on.
