M4 DCT Fuel range?

[donkamio]

Hi all

Looking to replace the trusty Scirocco diesel with a used M4 dct next month with approx. 10k-15k miles on the clock.

It will be my daily. I am doing approx. 300 miles a week with a mix of 50% mway, 30% a-road, 20% busy town driving. My driving style is quite relaxed.

I've tried to find information out about the 'true brim to brim efficiency' and fuel range of this particular model but it seems to vary quite a lot with most owners reporting mpg of brand new cars. The cars that are now broken in should start to return better figures

The tank is 60l so fill up cost £65-£70. Can I expect a weeks (or more) driving on a tank? Any other owners using their M4 daily? Any true mpg figures?

Always wanted an M and now is my chance but the head says Panamera v6/640d

If you're gentle, you can easily get 350 miles from a tank..

I checked this morning and have averaged just over 22mpg in the first 3900 miles of my ownership
Weekly drive is 120 miles motorway (Mon am, tragic M25 grind/Fri pm M25 blast) and 5 miles Mon-Fri town drive. Weekends are 50 miles mixed. Every now and again I have a proper blatt. Everything turned up and windows down really does burn 97ron...

I know that is low miles so expect worse economy, but those numbers are the same as my E92...

Also OP - 300 miles per week with an M-car?! Christ. I do ~60 a week in my M3.

300 miles per week is nothing. I used to do 400 plus in my M5

[Schermerhorn]

What is the tank size on one of these, are they still 60 litres?

[cerb4.5lee]

Obviously nowhere as exciting as a M4 but as a guide we get around 600/630 miles out of a tank in a 640d...but stick with the plan for the M4 though!

[donkamio]

Thanks all. I certainly would relish 350miles from a tank.

I think 15k miles pa is just on the cusp of acceptable for such a car, any more and the fuel/depreciation would be too heavy to justify. Interestingly a number of the mid-2014 cars for sale have done 18-25k miles in just over a year!

I did 38k over 18 mths and averaged 22mpg BUT 28k of those miles were done on the motorway, around town the engine is very thirsty even with DCT and stop start, a spirited b road blast will yield 14mpg easy.

I would budget on 20mpg overall, plus what's the point in having that engine if you're not going to use it.

Ah I've seen you are talking about the new M4 ignore the above!

I doubt you'll manage a week on a tank.

You could be £20 out either way and if that makes the difference in your decision making then is this the right car for you?

Had a wee race with a motorbike (600 I think) tonight. Two thoughts - my M4 is f@%king fast and where has my fuel gone...

Indeed I do 600 miles per week in my M5

Used to regularly get 300 miles from a tank out of my E46 M3 and more if it was on long motorway runs. The published figures suggest an M4 should be around 10mpg better than an E46 M3 so even if the tank is a little smaller (think it was 63 litres on the E46?) I still think you should get 300 miles between fill-ups from an M4 (although 20% driving around town won't help the cause!).

I'm also averaging 22mpg in my F80 M3. I get around 230 to a tank. That is with a mix of driving, driven as they are meant to be you'll see low teens, on a motorway at 80 ish you can hit high 20's or even low 30's. Although I very rarely take mine on the motorway.

[cringle]

I do mostly city driving in my M4 DCT, obviously depends how you drive but I get 220 out of a tank, if I have to do any longer motorway journeys then between 270-350. 350 when sitting for long periods through 50 mph roadwork sections. You should manage a tank a week unless you have a particularly heavy right foot.

An M4 has a 60 litre tank so 220 miles between fill-ups implies less than 17mpg; even the urban figure for a car with DCT is 25mpg so to be getting down in the teens on a regular basis implies a very heavy right foot! Not saying theres anything wrong with that but surely someone with the OP's "relaxed" driving style ought to see significantly more than 17mpg from an M4 DCT?

[Wills2]

But you'll never run the tank dry and therefore if you fill up when the light comes on, it's going to be around that figure, I was knock off 20% from the official numbers and see that as the real world MPG.

If someone says they get 220 miles from a tank I interpret that as the typical range quoted on the trip (which assumes you'd run the tank dry even though in reality you obviously wouldn't!). In my experience petrol cars aren't as much as 20% off their combined figure but even if an M4 DCT was that still would equate to a range of over 350 miles (and therefore over 300 miles between fill-ups without worrying about running dry?).

[Wills2]

OK, call it usable real world range then as in the point you would refill the tank, BMW advises strongly against running M cars low on fuel so it's always advisable to not run them on fumes.

Could be my usage profile but I always seem to get around 20% less than the official combined cycle on the petrol cars I've had, others will have different experiences.
