Hi,

I bought a new Cooper D in May which has now done around 5600 miles

I put in half a talk of fuel and it gets 140 miles. From what I have read this is way too low as people expect to get 450 miles out of a full tank

I live in Sheffield and at the top of a hill therefore there is a lot of hill driving (for those who don't know, Sheffield is in a valley so is very hilly. Any ideas if this could be the problem?

Average MPG currently reads 49.5mpg and hasn't been reset for around 2000 miles. If I go on the motorway this does increase to closer to 50 but I am wondering if I should speak to a dealer about it

Driving style is normal. When I go to work or the gym I can go most of the way without touching the accelerator!

It's been going on since I first got the car though so not just in cold weather. It has lowered lately

But even in cold weather, should there be a difference of 170 miles per tank between what I get and what others get?

I have a PSA engined Cooper D 2009 which has done just over 40Kmiles now and has settled in at 60mpg or about 430miles before the first fuel warning alarm. I dont drive for economy but dont spend much time in town. My journeys are rarely less than 10miles long so little cold running.

Had a 2011 Cooper D as a courtesy car recently (7000miles on the clock) in which I did a 700 mile round trip in a day cruising at 70ish most of the time. Computer said 49 - 50 mpg average and the first fuel warning light came on at about 330miles. Did a rough check based on the amount of fuel put in and 50mpg was about right.

So it would seem that the BMW engined D Cooper is about 10mpg less economical than the PSA engined cars. The former is smoother and quieter and feels abit stronger in the midrange than the latter. Disappointing economy though.

May just have to get a Cooper S petrol next time. :biggrin:

I'm afraid I've fallen into the BMW diesel engine fuel economy trap. Just part exec an 08 PSA and regularly got 63 mpg without even trying. This new (60) BMW CooperD is a real disappointment. Even though the road tax is zero, I think I'd prefer the £20 a year tax and 60+ mpg any day.

Hi, this is my first post!

Got my 07 PSA Cooper D a couple of weeks ago and the computer says I'm getting 63MPG, but the app on my phone that calculates the actual figure says 58, so don't trust the on board computer!

Still, this is loads better than the Mazda 6 I had before, and I love the way it handles.

I only get ~44mpg out of my 2011 Dooper. That's with majority town/city driving with a 150 mile round trip every couple of weeks. Trading it for an S soon :D

i do 16 miles in my BMW Dooper each day i get about 45-55mpg.


But when i used to go home every weekend on the motor way id comftably sit in the high 70's and once when i did a super economy run at 56mph behind a truck running Vpower i got 95mpg on the clock and topped up when i got back and got a range of 804 miles.:confused: somehow i dont think thats possible!

worked out how many litres i put in and did the maths. it ran at 82.375MPG so only just got its book figure!

Only get 41 mpg our of my dooper 08 reg rubbish got more out of my beemer 320d thinking of changing of course bmw/mini say there is nothing wrong (computer says no) must be my driving.

72.4 mpg yeah right then i wake up !

I do agree that the BMW engined Doopers are appalling. Ours usually returns mid 50's. It's done approximately 8500 miles now. I was hoping it would improve, but...... Strangely, the computer always reads under the actual return.

BMW must be one of the biggest con-artists in existance, but we're daft enough to fall for the hype.

Thirsty, and badly built (lots of rattles and squeaks) about sums them up!

Can someone please supply me with some rose coloured glasses?

Strangely, the computer always reads under the actual return.

It's interesting, I keep a spreadsheet of every fillup with calculated mpg and OBC mpg. Sometimes the calculated is higher and sometimes the OBC is higher and my suspicion is that my calculations are the more inaccurate as I can never be sure the tank is brimmed to the same level each time.

Best I've seen over a tank (calculated) is 67.9mpg, worst is *ahem* 41.3mpg, although I drive for enjoyment rather than economy :D

Hi folks,

For what its worth I drive a MCS and do mainly town driving all day and average 33mpg when I do have to use the motorways it goes to 47mpg at a steady 70mph.

But when you open the taps and unleash that supercharger she drops a lot.:D

I am on my second Mini Cooper D. The first one was a 2008 Cooper D with the PSA engine which averaged ~50mpg in commuting into and out of London over a period of 26,000. On this car the OBC was always more optimistic than the actual consumption when calculated. The car was reliable with no rattles or squeaks and only had one fault which was the electric boot lock failed which was replaced under warranty. Best fuel consumption achived on a full tank with motroway/dual carriageway running was 65mpg.
The second one is an LCI model Sept 2010 built with the BMW diesel engine. On exactly the same journeys into London and back, this car is averaging around 52mpg on the OBC but when I calculate the consumption it is around 3- 4 mpg more. So this car's OBC is consistently pessimistic with regard to fuel consumption. The car has no done 16000 miles with no mechanical/build problems and I have no rattles or squeaks nor have I had any faults other than a blown HK amp which was replaced under warranty. I find this later engined car to be much more refined and quicker to drive. On a long drive this car will return 65mpg easily.
Overall, I am very pleased with the Mini Cooper D and relatively content with the consumption.

Hi all

I used to have a 2008 Cooper D and used to get about 500 miles per tank!

Now i have a 2010 Cooper S and i get around 420/430 miles a tank from just normal driving mostly round town and a bit of motorway! When you think your paying more for diesel! Currently round here diesel is 8p a litre more than petrol!

The savings from having the Cooper D previously aren't even worth mentioning unless your doing well over the average mileage! To be honest i don't really notice any obvious difference in money fuel wise unless i work it all out.

If im really really really careful and drive like a granny! I can squeeze 55mpg out of my Cooper S on the motorway doing around 60mph! Happened to find that out in slow moving traffic the other week! :( lol

In the past ive always had diesel cars but now ive had this Cooper S i just can't justify the need to have a diesel anymore! The Cooper S isn't exactly the most economical car either! I was suprised at how little the difference was between the Cooper D and the Cooper S!

Only 70 miles per tank difference, does not sound a lot until you take in to consderation that your S tank holds 10 litres more which is about another £13-14 to fill up.

Lost Prophet when you say...

Are you going by the fuel gauge reading? Because when my car reads half a tank it's less than that. I always fill mine up, if you're not used to doing that it feels painful to hand over the best part of 60-65 quid in one go but in the long run it saves money. No need to drive to the petrol station more than you have to!

How many litres or how much money's worth are you putting in it? I think that 50mpg is average for most diesel engines around this capacity it's not just Mini that have optimistic economy figures. My previous two cars (company ones not by choice) where a new shape Corsa 1.3CDTi and a Toyota Auris 1.4D4-D. They both had quoted figures of over 60mpg... guess what they both did 50 all the time!

The car companies have UK consumers sucked into 'Diesel is the cheapest' way of thinking and it's just not true anymore. The last time this was the case was when Peugeot brought out the 1.9TD that they put into everything in the 90's. That engine was fast, gutsy and did 50mpg stood on it's head way before all these new engines came out and back then diesel was cheaper than petrol. Also the engines where simpler and had less sensors on them so they didn't break down all the time like modern ones do!

I'll take my 180bhp Cooper S petrol at 37-42mpg consistently any day of the week. I've never been a fan of diesel and I am less so now, why do you think all the new hybrid stuff is petrol powered?

ScoobyChris
Mar 1st, 2012, 12:54 PM
Lots of new hybrids are going to be diesel rather than petrol - Peugeot, Citroen and Volvo to name but a few.

I think at the end of the day, it comes down to how you drive. I know that I can hoon around in a diesel and drive like my hair is on fire and still return 50mpg. If I were to do the same in a Cooper S I'd be seeing half that mpg.

I know which would be the more fun to drive, but with high annual mileage, diesel is saving me quite a bit of money while still allowing me to have some driving fun. :D

Damn! What are you guys doing? I have a 2009 Clubman D (76,000km) with the PSA diesel and I have NEVER had it more economical than 4.7L/100km which works out to about 50mpg. What's more "normal" for me is about 5.1L/100km or 46mpg. It's been like this since I bought the car. I've tried different fuel qualities and I've tried driving like a grandmother (very light acceleration from a complete stop, gentle gas on the highway, use of stop/start etc...). Best I ever maintained was 4.6L/100km or about 51mpg.

According to what's being reported here, I should be closer to 4.0L/100km.

I've got 15" rims and religiously check tire pressure, air filters and oil level/filters. I don't get it. I even do overwhelmingly highway travels with no stop and start.

Anyone have some advice?

I used to own a Clubman D with a PSA engine in it and I could get it in to the mid 60's easily without driving like a granny and that was on 16" wheels. Remapping it made no difference to economy.
The newer BMW engine is a different matter though, on 15" wheels on a 3000 mile trip round europe my previous car a MINI R57D did 60mpg, when I put back on the 17s and went back to my normal daily driving at mix of motorways and urban it was down to 53mpg.
My current MINI a R56 SD does better (56mpg) on the same roads on 17s

You think it's down to tire size?

I'm a little puzzled, I would have expected much better mileage out of this car, instead I'm struggling to maintain 50mpg. Car was just serviced and there were no issues with it.

What can cause a drop in mpg besides the usual suspects (dirty air/fuel filters, bad tire pressure, etc...)?

I had a Mini One (petrol) as a loaner during the Dooper's service and I was gettting about 6.5L/100km (36mpg) out of it, so I thought my Dooper was pretty economical. Apparently I'm getting less than average out of it according to what I read on here.

I have a 2008 Cooper D Clubman and regularly get 58-60mpg (real mileage and not onboard computer). I am sure that tyres make a big difference and this is noted on many threads in the forum.

I have had the Clubman for 10 months and when I bought it, I deliberately avoided any with 16/17" wheels and run-flats. I know they look great, but part of the reason for buying the Clubman was economy and in my experience, these do nothing for your economy. If you are on run-flats, ditch them as soon as you can and you may see up to 6/7mpg difference. Combine this with a change from 17" to 15" wheels and you should see about 10mpg.

When BMW do their tests, they are in the best conditions. Warm engine (well run in), warm weather, perfect tarmac road, correct tyre pressure, slow acceleration, 15" wheels and economy tyres. Most of us will never achieve this and we wont have much fun trying.

I have a One D Clubman which I tihnk have the same quoted mpg as the Cooper D and I'm nearly at 1000 miles in it now and last time I filled up I did the calc and it came out 52.0 ish mpg and my OBC is saying 51.0 ish at the moment. I was hoping when it runs in I will get up to 60 ish mpg. Going to reset it at 1200 miles (the book run in period) then leave it as a lifetime average and see what happens!

......

That is on 16" Wheels, none run flat Michelin Energy saver tyres and its quite cold at the mo, mostly all miles under 10 C and alot at -3 to +4C.

Mar 7th, 2012, 12:45 PM
Peterand I have to say from my experience with tyres recently I don't agree with you there. I've just taken my R56 Cooper S off run-flats, on the run flats I was doing 38mpg without trying and sometimes tipped 39mpg. On standard tyres i'm returning 36mpg average and really have to drive carefully to get back up to 38-39.

I think part of the reason BMW favour the run-flats is for reduced rolling resistance and better economy, it just gives you a terrible ride in a Mini in my opinion.

Just for my 2 pence worth, my cars just been in for a service and I had a Mini One D 2011 with just under 10k on the clock. I drove it normally, but with economy in mind but not over the top. Only going by the onboard but I managed to get it to 59.5. Gutted because I was hoping i'd tip 60. This was mixed urban and A roads no motorway.

However if the quoted figures are over 70 I can't imagine ever achieving that in real world driving!

Thanks Poprin, I think that this is a hotly contested issue.

Fortune (or misfortune) had it that I had to get a new tyre today, so I asked the chap who owns the tyre dealership what he thought. His view is that run flats reduce your economy as they 40-50% heavier than a standard tyre because of the thicker sidewall. Also, he said that they have about 20% higher rolling resistance when compared to standard tyres and create more friction.

His general recommendation is to get rid of run-flats, but he added that the type of tyre and making sure that it is always inflated correctly makes a significant difference.

Help, I am turning into a tyre geek!

Mine's on 16 inch Bridgstones (non-runflats) with correct pressures, and even gentle driving only returns mid to upper 50's (2011 BMW engined Dooper).

caveman_dave

All my experiences of mpg on differing sizes of wheels are on Non-runflats, different brands of tyres do make a difference which will down to rolling resistance. Weight of tyres is not going to make a massive difference unless you are comparing with runflats that are on average 2kg per tyre heavier.
My only experiences of 15s have been fitted with Michelin Energy savers, but on 16's I have had the opertunity to compare Pirelli and Michelin tyres, and the Michelins are on average 2mpg to the good.
Another thing to watch is wheel weight, I ran some Imola (pepper pot design) 15's which come in at around 5.5kgs or 14kg with tyre, compare that to MINI's average 16" or 17" wheels of around 10-11kg or 20-22 kgs with tyre and you start to build up a lot of extra weight which is going to cost you.

And 70mpg in a PSA engined car is achievable on country roads but its no fun.

If you have cruise control, try setting it at 70mph (where safe), reset the obc and see what happens, the cruise control is far more economical than your foot as it is maintaining perminently with minior ajustments that you will never be able to achieve, I reckon its worth another 2-3 mpg.

As for the offical figures, well they are all set under lab conditions to create to 'fair' comparison, which is no help in the real world as all manufacturers can adjust there map to suit the lab test. I wish they would bring back to old 30, 55 and 75mph figures, atleast that way you would be able to compare what they are like on motorways where I guess most people spend most of there time while driving.
Just as an aside my wife used to own a Polo bluemotion which was supposed to be even better on fuel than her MINI, it wasn't by a long way.

Interestingly, I have just looked at an Auto Express tyre comparison test from the back end of 2011, and they rated the Bridgstone 10th out of 10 for rolling resistance (and 8th overall!).

I have found this thread really interesting. As I said above, I have had a 2008 Cooper D Clubman for about 10 months, which has the PSA engine. I have driven 2 new Coopers as courtesy cars and I found the BMW engine to be smoother, more responsive and quieter. But, I did notice that fuel economy was noticeably different.

My plan was to keep my current Mini for about another year and then PX it for a BMW engined model, but as economy is important to me, do you think that this is a wise move. All the reports on this thread seem to point to poorer fuel economy with the BMW unit?

MiniDeLux

Well, I revisited my fuel consumption. I was converting 4.7L/100k to U.S. mpg, which gives 50 (U.S.) mpg.

Converting to UK measure, 4.7L/100km converts to ... 60 (U.K.) mpg.

So looks like I'm actually spot on what's being reported here (assuming you guys are using UK mpg).

I would imagine that this will improve somewhat in the summer. So it seems to be true that the PSA engine doesn't do too badly in terms of fuel consumption. It definitely uses less that the Mini One petrol engine and BMW diesel engine Clubman I've had as loaners. The BMW diesel engine loaner I had was using 5.6L/100km (about 50.4 UK MPG and 42 US MPG).

Hi everyone

I am looking at getting a new hatch Cooper D. Would 16" wheels make a big difference against 15" as to what economy I would get?
