Just wondering what fuel consumption you are all getting with the new BMW engine in the Dooper.
My wife uses our car mainly. She does a 35 mile run each way to work most of it is fairly clear A roads with a few miles of urban traffic, normally she averages near to the claimed average fuel consumption on other cars we have had. She is not a particularly hard driver by any means.
On the Dooper it is nowhere near the claimed 74mpg average Mini claim.
The car currently only has a couple of thousand miles on so I guess the engine could still be a bit tight and it could improve a bit yet?
Current average for us 52mpg! I know this is not bad but it is nowhere near Mini's claim.
I'm interested what others with this engine are getting.
Please let me know.
Thanks.
Mine is 4 weeks (and 2 days :biggrin: ) old with 1100 miles on and over the last 3 tanks, I've averaged 47.0, 48.6 and 46.6mpg. However, I tend to have a heavy right foot, especially when the roads are clear, and most of my journeys are fast A and B roads so not much opportunity to capitalise on the stop/start technology.
Popping into the Countryman forum, it seems that the BMW engine loosens up nicely after around 5000 miles and the economy starts to increase after that. Whether it does - ask me in 4 months time LOL

The stop/start technology only comes into it's own when you are in urban traffic and believe me the Dooper consumption drops quite badly in urban traffic. Stop /start technology is mostly about reducing pollution and Co2 emissions rather than reducing consumption.
Car is 5 months on just under 5000 miles. When running the car in I thought the new BMW engined Dooper was more economical than the Peugeot engined one which i ran for 2 years and 25000 miles. However since the running in period the consumption has averaged around 50 - 52.6 mpg on the computer. The computer is unusually for a BMW pessimistic so the 52.6 mpg equates to a measured 56mpg. Even so none of these figures are anywhere near the 74 mpg.
50 - 55 is about what I get. I've Winter tyres on at present which probably costs a little and I've a feeling that everything improves a little in Summer. I could get it up to 70mpg by trying very hard and driving it like an old 2cv but except as an academic exercise there's really no point. In the real world, a car which will do 120mph and 50mpg is pretty good.
It is very interesting to note that we all seem to be getting pretty similar fuel consumption. We have to ask though where on earth did BMW?Mini get their officially quoted fuel consumption figures from? As I previously said we have always with other cars we have had, got near to the published fuel consumption figures. We used to get 52-53mpg from a Mk4 TDI Golf with a 1.9 ltr 150bhp engine, bigger engine, heavier car older technology. To me this makes 52mpg from the Mini seem not that great nowadays. Don't get me wrong we love the car it is though very disappointing to get fuel consumption of 22mpg worse than the quoted average. If we had realised that 52mpg was going to be our average we may have even chosen something else based on this.
Had my Clubman D since October and over 3900 miles I've averaged 45.2, and I've been trying to drive it like a vicar! My old 2008 PSA engined Clubman D averaged 53.3 over 38500. I'm hoping the engine will loosen up as mentioned after 5000.
Ours is 5 months old and has covered 1300 miles. Cant seem to get more than an average of 52mpg although it is mainly pottering around in the cold weather and has low mileage so the engine is still tight.
In 3 months Im taking it up to denmark for a couple of weeks and will cover at least 2k miles so it will be interesting to see what I get on a long steady run.
I also get 58-62 mpg and I do mostly Motorway mileage with cruise control set at 75 mph (TomTom GPS says 70 mph)
I've done 5k miles now and it's been the same from day 1 in December 'til now and that includes changing from winter tyres to Michelin Energy std tyres on 15" 175/65/15.
I will be changing to 17's 205/45/17 soon so will see if that has a negative effect on mpg
I've just traded in from an 06 Petrol Cooper to a Dec 10 Dooper that's only done 1700 miles. My petrol did about 39.5MPG, so hoping really to get about 59 out of the Dooper. Not expecting the 74 they say!
Just got back from holiday with a ~200 mile motorway round trip to the airport. Fortunately, early morning and late night driving so very little traffic to cause problems and I gave the cruise control economy a test. Set the car at a steady indicated 80mph in 6th which was maintained on all but a couple of 50mph stretches and the OBC is showing a lowly 44.8mpg! Quite disappointing considering my usual driving hacking across A and B roads easily sees 50mpg from a tank now.
That's very interesting - in identical circumstances, my petrol justaCooper does 39-41mpg (measuring by odometer/fuel pumps). I would love the extra torque of the diesel, but only 5mpg better makes it hard to justify the cost.
Mind you, 150 miles of B-road hooning lately got me 32mpg for most of a tank, so high-speed cruising is where the petrol justa is at its best.
Car has a smidge over 4k miles on, is running 16" wheels with non-run-flat Bridgestone something-or-others. Two adults and associated luggage, climate set quite low (18 degs?), xenons on and on the way back yesterday night the auto-wipers working overtime through the spray.
The trip was mainly an opportunity to test the theory that cruise control is more economical than not - I need to rerun it again just using my right foot, but I'm confident I could easily better that and get at least into the mid-50s, especially considering during hooning on the fun roads, I'm seeing more than I got on this last trip lol
I've had cruise of loads of my cars now and it certainly doesn't help save on the MPG.
I find there is more to be found MPG-wise by slipstreaming cars at a variable speed set in your mind (say anywhere between 70-80) and then the wind resistance drop gives you much better economy.
Cruise does what it does brilliantly - keeps you at the required speed, meaning it will really floor it up hills if it needs to, probably where you would have backed off a bit. It also can't think 'downhill a bit faster then up hill a bit easier' etc.
The aircon doesn't help but xenons actually draw less current than normal headlights (35w each if I remember correctly)
80mph on cruise must also be tough on it as the drag must be huge at that speed vs 70mph.
That was my theory of cruise, but a few people had recommended it as more economical so I wanted to do my own experiment Interesting info on the xenons too - I'd assumed as the light output was so much better that they drew more power, but doing a bit of reading around it looks like they are much more efficient!
If I'd been a more patient person, I'd have set the cruise to 56mph to compare with the book figures, but I'm not and sitting on a completely clear road going slowly upsets me lol I also have a broken left hand side-repeater which must increase drag slightly too lol
Setting the cruise at 80mph is not going to give you good economy as it is well above the 2000 rpm limit above which fuel economy drops off for the Cooper D. I did an experiment this morning setting cruise at 80mph on the flat and the instant mpg was around 50 - 52mpg. Setting the cruise at 70mph again on the flat gave figures of 68 - 74mpg quite a big difference.
Interesting - peak torque (ie where the engine is working at its most efficient) is between 1750 and 2250rpm and 80mph is within this range. In fact it's only a smidge above 2000rpm as the ratio looks to be around 35mph/1000rpm in 6th by my crude reckoning so perhaps the big factor in adding 10mph is actually the increased wind resistance.
Either way, the aim of using cruise control wasn't to drive as efficiently as possible, it was to compare the economy to my normal runs without cruise control (with a similar cruising speed)...
I've kept spreadsheets for my last 3 cars - some of the numbers make disturbing reading :redface: lol
