Hi,

I buyed my Mini Cooper two month ago and now on 1500km - 930miles.

Use my car mostly on urban , very calm and mid mode. (car is automatic). My fuel consumption is 8.5-9lt/100km - 33/31 mpg, but in the catalouge says 5.9lt/100km - 48 mpg.

Why my car spens more fuel than normal? Sould I go to the service? Please help ?


Sorry for my bad English.

Hello eymenthe, and congratulations on the new motor! (How about a pic?) I hope you're enjoying yours as much as I'm enjoying mine (F55 MCS auto), which I've also had for 2 months. Re. fuel consumption - all I can say is that I've also found fuel efficiency to be quite a bit lower than what I was expecting. I'm currently on 9.5l/100km = 29/30 mpg (British), but like you I'm mainly driving in the city and I have quite a bit of slow, commuter traffic to get through. Last month I did my first highway run - 100km round trip with mostly smooth cruising - and my fuel economy jumped up to 8l/100km = 35 mpg (British). Maybe you might want to talk to your service centre and see whether they think there's anything unusual with your fuel consumption, but my guess is that what you're getting is about right for city driving. In my case, I'm filling up a bit more than I was expecting, but I'm having so much fun driving I've resolved not to worry about it too much!

I have a 15 MCS and I consistently get 30-31 mpg. I do 75% town driving and the rest highway.

Is that US mpg?

Sorry, yes, US.

My mcs auto returns avg 37mpg uk according to the computer. I havent actually measured it myself yet

Well you're gonna have a hard time to match the manufacturers figures, those are always optimistic. On top off that your engine is brand new and will over time get better fuel consumption.

Other than that it's very hard to tell if it's normal or not without watching you drive. Doing things like letting off the throttle a bit earlier instead of slamming on the brakes etc can save you a lot of fuel during urban driving.

I had a consumption of 6.2 l/100km the first day of driving. Which consisted of 50% urban driving and 50% motorway driving with speeds of 120km/h.

If I play around with the the car slamming on the brakes and accelerating hard it seems that anywhere around 8-9 l/100km is what I can expect with the car atm. I'm expecting it to drop 0.5-1 l/100km when I've gotten some miles on the engine.

My Cooper, non S, is averaging about 45mpg /uk in mainly urban use, but improves a lot on a run, nearer 50mpg.

I would wait until the engine has been broken in, and if the mpg is still poor there is obviously something needing tweaked by Mr Dealer, methinks.

My suspicion is that the Mini fuel consumption numbers are also based on driving in green mode a lot of the time. Since I drive on the other end, I'm getting in the high 20s (26.5). Still better than my last car, and WAY more fun. Gas in the US is cheap right now so I'm not bothered.

 

[caveman dave]

The fuel figures are based on start mode, EU regulations only allow data to be quoted in start up mode, but they are also based on the model without extras which would mean smaller lighter wheels with narrower tyres in most cases.

As an aside my Cooper D is returning an average of 64mpg.

30 us mpg is about 38 UK mpg.

Have to calculate the equivalent in USgallons, that sounds good.

 

[littleblackdog]

Dang its a Diesel, no wonder! So wish we had them in the US.

It is entirely possible to match advertised fuel economy figures, but most of the time road and traffic conditions mean that they're difficult to achieve. If I set my MCS to 50-60mph using cruise control it will return 60mpg (UK gallons) all day long. If I drive it around a city shopping at junctions and sitting in traffic it will return little over 30mpg. Traffic, weather, junctions, braking habits etc. all plays it part..... If I take it out for a Sunday blast (on a track of course) then I'll get less than 20mpg.

I disagree. I have tried my absolute best on some journeys and never matched the official figures.
The f56 Cooper is quoted as 49.6mpg urban, 74.3 extra urban and 62.8 combined.
A gentle cruise will get about 55 or so which is still good for a petrol car.
In cold weather the official figures sre even less likely.

It's all down to alot of things. Such as weather, tyre pressure, traffic, the way you drive etc etc. It's extremely hard to reach manufacturer figures but it is possible to even get under them. Top gear magazine wrote about a competition a few years ago that was about how low you could get under the manufacturers figures. The winner was someone who drove a Golf R at almost twice the mpg that VW had quoted.

Top Gear talk a load of rubbish :-0...

Let's see if anyone on here can actually match the figures.

It is not MINI's fault. The way they test cars is totally unrealistic. I know What Car magazine quote "true mpg" figures gathered in real life, far more useful to potential owners.

I get 45 - 48 mpg overall in my f56. I am happy with this as the performance is far better than my r56 Cooper which did about 40mpg. Also fuel has come down quite a bit in cost, an additional bonus.

 

[lawrothegreat]

From personal experience you can match the combined figure over a whole tank, but it takes effort and you'll need to drive far more outside of a city, than within, which differs from manufacturer test conditions.


I once achieved 50mpg (UK gallons) over 540 miles in a 2007 MCS from a single 50 litre tank. The car was reporting 53mpg, and I measured 50mpg pump to pump. The advertised combined fuel consumption for the car was 45mpg.


I've achieved similar results now across four new cars (3x BMW/MINIs and a Toyota).


Braking is the enemy of fuel consumption, the more you can eliminate it, the lower your consumption will be!

 

[kenl]

Interesting!

What are your figures for your f56S over 17k miles?

"Drivers also sought to find who could register the greatest percentage improvement over the motor manufacturers’ published fuel consumption in the sternest test of skill and anticipation. Clear winners in a Vauxhall VXR8 were Andrew Duerden and Chris Mooney who with 32.14mpg crafted their way to a 53% improvement over the car’s combined cycle figure of 21.0mpg. Second place in the percentage improvement class with a 48% uplift went to twice former winners David Madgwick and Ashleigh White in a VW Golf R 4 Motion, with Cracknell and Randle also claiming a rostrum position here with a 28% improvement on their car’s 67.3mpg combined cycle figure"

Im not saying it's something that's easy to do, just saying it's possible and goes to show just how much it matters how you drive.
