I've been following the Fuel Economy topic with interest... but only the owners of petrol-engined cars seem to be posting.

Therefore, I thought me & my fellow diesel disciples should have somewhere where we can boast!

My Cooper D now has now covered 3k miles and is delivering over 65mpg on a mixture of town, country & motorways - mainly on the Mid setting, but with Sport sessions & Green for motorway runs. (Tyres are 16" run-flats).

With the 44 litre tank, the full range exceeds 650 miles (does anyone know why the MCP only has a 40 litre tank?) and the real-world performance of the Cooper D is absolutely brilliant.... if you've got one on order - rejoice!

That is fantastic.

I have just driven about 35 miles in my Cooper and the trip comp showed 55mpg.

Could the diesel tank just be bigger to give a higher headline range figure?

I dunno... The Cooper S also has the 44 litre tank - it makes no sense to me! When did you get your Cooper D?

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 took delivery of my Cooper D at the end of June, (replacing a petrol Cooper R56 which averaged 48mpg in mixed use).

Having now completed 4000 miles - my F56 is averaging around 68/69mpg - again for mixed use, with Green mode selected for Motorways & dual-carriage A roads.

Odd that your car is far from achieving the same....?

F56 cooper d

We're up to 2500 miles in ours, probs averaging about 65 but if taking it easy on my commute I have seen over 70 (35 mile commute). Needs to be really tickled on the throttle to return that with short shifting on the gears.

Their is no way to achieve Mini/BMW MPG. My BMW 1 series is at least 2ks off. What I have found is just turn the MPG off and enjoy the car. The difference in cost for a few extra miles is nothing.

Mini/BMW are not designed for nanny drivers they are drivers cars with some fuel savings.

Do you remember the average for the first 1000 miles ? It differed too much from the current 68/69 mpg?

So far managing a paltry 44mpg in a MCSD - this is on 20 minute daily commutes two or four times daily with not much in the way of traffic. Only done 600 miles in the car so will take it on a longer few journeys to see if that makes a significant difference but so far underwhelmed at what I'm seeing.

Hi,
I've got the 3door MCSD, just short of 3k miles on the clock, and at this time I am still running in as per a 'Honest John' article, upto 1k no more than 3000rpm, upto 2k no more than 3500 rpm and at the moment I'm on the upto 3k no more than 4000 rpm.
Obviously on the first 1k with only going upto 3000rpm the mpg was better than now, I like you have a short commute of about 13 miles each day, and initially I was getting late 40s-early 50s mpg, more recently on using higher revs it's been around the 44mpg, but considering this is from a cold start and noting that the engine temp only shows OK after the first 6 miles when it will be at it's most efficient I think this is acceptable, also at this time of year the heated screen/ seats/lights are also on and a drain. I have made two journeys from Kendal to Manchester set the cruise at 70 mph and both times I reached 60 mpg.

What I dont get is why BMW drivelines perform much lower fuel efficiency in a Mini?

My f55 diesel careful driving: 5,8l/100km
Our 2011 BMW 116d, not carefully driven: 5,8l/100km
The loaner Countryman SD carfully driven: 7,2l/100km
The neigbours Countryman D: 6,9l/100km
A collegues 320d 2014 xdrive: 5,5l/100km
A collegues Volvo V70 D4: 5,6l/100km
Our old Saab 93TTiD: 6,8l/100km
The wifes Kia Sportage: 6,3l/100km
A friends 320d auto 2012: 6,5l/100km
A Collegues Volvo XC60 D2 2015: 6,2L/100km
A friends Volvo XC60 D3 Auto 2014: 6,7l/100km

The conclusion I'm comeing to is that the Minis in general are WAY to thisty compared to other larger modern cars, why is that?

I have to disagree. From my fuel log I have data for my last 4 cars.
Averages and total miles
MINI Coupe JCW 34.23mpg 8471 miles
Countryman SD ALL4 45.15mpg 22245 miles
BMW 116D SE Auto 57.53mpg 13232 miles
MINI Cooper D F56 (current) 64.6mpg 2051 miles

Conversion to MPG on your top 3
My f55 diesel careful driving: 5,8l/100km........48.7mpg
Our 2011 BMW 116d, not carefully driven: 5,8l/100km...........48.7mpg
The loaner Countryman SD carfully driven: 7,2l/100km...........39.23mpg

I would put it down to your driving style

People have to remember that Official figures are done on a rolling road, with the extra urban figures at a max of 55mph, if you drive around on country roads at 55-60 mph max and set the cruise on the motorway at 70 mph you will get very respectable figures.

Also do people really expect a car with 170hp to return 75mpg,

The fuel economy test is just like the exam results that we all like to quote - we swatted for hours the night before and there's not a cat in ****'s chance we could achieve the same result today without warning....

I wonder if poor Mini diesel fuel consumption figures arise from people enjoying driving them and hence not driving very economically? I've got just 48mpg (5.9l/100km) from my SD Roadster over 30,000 miles, but then I regularly travel on empty windy roads that could double as tarmac rally stages, so I can't be expected not to have any fun. Driving a diesel Passat economically would come naturally - but staying awake would be the big problem.

To be fair I don't see that much difference with my driving style. My MCS used to get around 38-45mpg going to work an back (13 miles each way) and the mini oneD that I've currently got as a courtesy car I'm doing 45mpg ands that's an average over 1100miles that I've done in it so far With the same trips. With the price difference of petrol and diesel I have no intention of loosing the 80 odd bhp for a very small saving.
I also heard that road tax for diesel cars will be going up dramatically either this year or next year. Not sure if that was just for business use diesels though.

45mpg in a ONE D, that is terrible! I am averaging that in my petrol Cooper in pretty slow moving commuter traffic.

With diesel costing around 30p more per gallon in the UK and also an extra £1K more in initial purchase price I just don't see the point in a diesel unless you are doing at least 20k miles per year.

Especially now that the petrol cars are turbocharged and have a decent amount of torque.

It may go up in the next parliment , as will additional charges to enter certain cities, but the EURO6 diesel engines will be exempt, therefore all F55/6 will be excempt from additional duty and city charging.

In a lot of cities in Europe you need a pass, the emissions of the car determine which areas you are permitted to enter.

This drive is down to EU regulations and will always give manufacturers a number of years to comply with new regulations before they are enforced.
