Took delivery of Cooper D some 2 months late at the end of June but have been disappointed at the fuel consumption. I know you should not take too much notice of the official figures but as this model is being advertised as being more fuel efficient than the last model that is what I was expecting. Our previous 11 plate which we had for 3 years averaged 60 mpg; on weekend trips away using A roads we would get up to 75mpg. After some 2000 miles the new Cooper D averages 53 mpg although we did manage 63mpg on a trip to the coast the other weekend using A roads. My wife is the main driver and there is no commuting; we live in a rural area with good A roads to reach nearby towns and cities and there has not been any change in the number of miles driven or routes used in the period of ownership of 3 different models. Previously we owned a 57 plate Cooper (petrol) and even that averaged 48mpg. The new Cooper D is disappointing when compared to our previous experience. Any thoughts?


I did phone Mini Customer Service and they said it was surprising and booked us in to our local Mini dealer next week. Don't know what they can do; presumably "something can be adjusted" but I am prepared for the usual "everything seems fine".

I reckon you need at least 3000 mls on it for true mpg but worth mini looking it over.just in case. Wheel size seems to make a big difference ie My r56 mcs does 44 all day on 16'' winter tyres but 40_42 in the summer on 17's. Can't wait to see what my mc does on Saturday. Yay

I guess you're using green mode...

Is the fish happy with your driving? I know it's been training me to change up earlier than I thought...

Are you measuring the mpg yourself or using the computer? I think the computer is a little optimistic (maybe by 2-3 mpg for me).

Mark's point is really important here - the algorithm used by your previous MINIs could be different to the F56 - measuring pump to pump yourself is the only real way to know what your car is doing. If you didn't measure your old cars pump to pump then have your fuel bills changed?


Having said that I would also expect more from the Cooper D. Normally you can achieve advertised fuel economy figures but only through very careful driving - I can achieve an average of 50mpg in my F56 MCS (advertised as 49.6mpg) but only through gentle driving, otherwise it's low thirties.


How many miles have you done? Are your tyre pressures okay? Is air con switched on etc.


Good luck.

I have measured the mpg pump to pump and it matches the computer. It has been pretty warm through the summer but with August being much cooler we havnt used the air con and the mpg is still 53-54. With our previous Cooper D we didn't even try to maximise the mpg; it achieved 60mpg consistently without any effort. I expected the new car to achieve much more and as it hasn't we have tried our best to get the best out of it; air con off, tyre pressures correct, green mode, careful driving etc. We will see what Mini service say next week.

Good afternoon friends! Really the intakes are well away from the announced .... I have cooper less than 2 months ... but already with 9.000KM . Fuel Consumption in city even in Green I can't download of 5.7L/100 Fuel Consumption in motorway in Green 5.2L/100 Very far of 3.5L/100 announced The maximum of miles that I did with a tank were 870km away too the 1100km announced.
Each time I think that the Bmw 530d e39 was the best car that I have had ... 3.000CC 184hp consumptions 7.2L /100 in city 5.4l/100 in highway ... twice the weight, twice the cilindra and more power ...

Hi, I have Cooper D which recorded its best figures yet on a trip in to work today. 50 miles at 82.3 mpg ! Cold start 6:30am Some B roads but mostly A roads and motorways max speed 60mph. So not sure what the problem with your car is but the higher numbers are certainly possible with the cooper D

Just for comparison my MC S has averaged 42.5 mpg (uk) per gallon over its first 700 miles as per the trip computer which others have suggested is not far off regarding accuracy.

This has been in green mode at low revs whilst running the car in - mostly motorway mileage with about a quarter of the mileage inner city stop/start style driving.

Pleased with this straight out of the box and the fuel consumption is slowly improving too.

I have covered 2342 miles in my 23 days of ownership. Yesterday I drove 250 miles form Gloucester to North Yorkshire mainly motorway. I drove at about 70mph with ACC on most of the time. I filled up today having covered a further 57 miles on the Yorkshire Moors. My phone app tells me that tankful to tankful I averaged 66.7 mpg over that distance. I am well pleased with this as the car still feels very tight. My previous Clubman averaged 56.4 mpg over 20,000 miles. This car has averaged 58.47mpg already. Interestingly last week I used green mode a lot and I reckon it wasn't as economical as running in mid mode.

im having the same issue aswell. I have done about 1500 miles and expected to do 20k per year. Alot of motorway driving, green mode on, cruise control down the motorway at 80 mpg with 2.1k revs. and I am stuck on about 55 mpg.

I changed this car from a petrol and im getting through the exact same days as i wouldve done in my petrol but this time its more expensive!!!

I was let down by this to be honest as I need a more fuel efficient car for work.

Diesels always get better mpg when they have covered lots of miles. When you get to about 20,000 miles you will be getting much better mpg. Try slowing down slightly on the motorway. I normally cruise at an indicated 72mpg.
