72000 miles in my 530d F11 and 35 mpg average since new. Mixed driving and like to push on. Will do mid forties at 85 on motorways.

My March 14 530D is averaging mid forties with a mix of local and longer trips, cruising at 70/75 on m ways etc.

I went from Norwich to Cardiff last week, via Milton Keynes, Cotswolds etc. 49 over that trip. Spent three days in and around MK on way back and getting back to Norfolk yesterday the average has fallen to 44.5.

I've done 14k miles in my F31 330d since October 2013 and I have only managed to average 32mpg. Most of my driving is maximum 20miles at a time. I must be doing something wrong!

Ouch. You've a lighter and more economical car than me (and I drive it fairly hard) and you are getting barely 80% of what I do...

My commute is c25miles at an average speed of 32mph

I've just been to take a photo because I'm genuinely intrigued...

So does this mean I have done 3977 miles (since last reset) at an average of 34mpg?

Sure does also 132hours of driving to do it -- its low I'd assume as its 34mph average speed so lots of commuting stop start type driving.


Do a non stop drive from Penzance to John oGroats and it would be much much much higher.

I guess that's the key thing IF you had the same powered petrol and used it as you do the 330d then it would be way down on the combined cycle.

Interesting that 3977 miles at 30.9mph would actually take 128 hours 42 minutes not 132 hours. 132 hours would be 30.1mph.

Did BMW not do basic maths?

I bet it wouldn't be. I'm still can't decide if I think the economy these cars offer is that great.

My 530d is basically 7-10mpg better in most circumstances (Except cold town work where it's no better) than my 530i was.

Thats progress guys - 10 years and a switch to diesel for barely 10mpg gain.

Never mind, it does a billion mpg in the brochure.

What's that gain in %age terms?

It's probably about 20-25% across the board really. If I try hard I can get 50mpg on a long Motorway drive but then doing the same in the 530i would touch 40mpg. Around town from cold it does circa 22mpg and the 530i about 18-20mpg.

My lifetime MPG so far is 35, on the 530i it was 27. Though if anything it's biased in favour of the 530d because I've used it for, proportionally, more long distance trips than I did in the 530i.

So, the 530i was within 10% of the EU combined figure. The 530d is nowhere near it.

Ah the petrol thing.How does it go " in my V8/twin turbo blah blah on the motorway I get 38 mpg!!!!!
Course you do ,,plodding along ,

However none of these drivers tell us what they get " keeping up with outside lane traffic" for mile after mile.Ie 85/90 mph

I wish they could get near a diesel in that situation ,id be in one.

Dear me - only 40+ mpg...

E46 330ci petrol. 27mpg, but it's worth it. smile

Why are you buying a BMW if fuel economy is the most important thing to you?

That's quite good for a 530i. Never got better than 40 out of our 2.0SE Z4!

But the 22 around town for the 530D would concern me. Ours gets up to near enough 40 on a local 6 or 7 mile run and just continues to climb to mid forties. Maybe if I was going a mile or so and the switching it off I would see 22 but not seen it so far.

I think the EU combined for my 530D is 50 or 51 . something. I wouldn't get that but can easily get within 10% of it.

My experience and view on mpg is similar to Fox. Did 500 miles from North Yorkshire to Kent and back in my F31 335d this week and it did exactly 43mpg for the round trip (the computer said 46 but it tells porkies!). That's about 14% down on the combined figure and arguably not bad given I had a bit of a delay around the Dartford crossing and wasn't really driving for economy; however, on the same run I'm convinced my E92 335i would have at least achieved its combined figure and would probably have returned around 35mpg. So yes the 335d gives better economy despite being in a bigger, heavier, car but the difference compared to the 335i almost certainly less than 10mpg (i.e. probably only about half of what the official figures would have you believe). That certainly doesn't make the 335d a poor car or a bad choice but to be honest I can't imagine driving in such a way as to achieve the combined figure; in contrast, on a run I reckon I could drive normally and do that quite easily in a 335i.

I bought a F10 535d on an 11 plate in the end.

12000 miles in I have achieved overall 36.6 mpg but that does involve plenty of performance driving as I get to do a lot of 4am cross country blasts and I've been exploring the new cars envelope which with adaptive drive is very very very large indeed. A particular s bend was absolutely on the limit in my e60 without adaptive on msport suspension at 52mph and the F10 SE with adaptive goes around it at 65mph and I'm not even sure that is the limit. It's a massive improvement.

Anyway. On an 88 mile run to work I get 43mpg if I drive nicely and stick to 75mph on the motorway. If I press on but drive in a manner to which my wife would not object I get 40.6mpg. If I'm late and hoofing it I get 38mpg. It's a mix of B road, bypass, motorway and through a City centre.

For nearly 300bhp and the effortless and delightful nature of the power delivery I consider that very impressive for a full size saloon.

I loved my E39 523i, I liked my e60 530d but I love deeply my f10 535d. Can't see myself having any thing else for the next six years or so. I'll probably take this one around to 180,000 miles then buy an LCI replacement that will be made next year. I think Bmw hit one of their occasional sweet spots with the f10/11. It's a discreet executive saloon that's as smooth as a jaguar as well built as a Mercedes as nice inside as an Audi but looks subtler handsome has everything you need as standard and so far appears to have no known serious faults. Apart from ubiquity they are pretty much faultless.

I was even thinking about if I changed my work to do less miles whether I could get an M5. A nice used one for £40k offers an answer to virtually any motoring question you can reasonably ask short of towing a horsebox. Best car in the world ever? Mr Spock the petrol head would have to say yes.

Then I thought to be honest I rarely get to use every ounce of performance of the 535d and the 300 miles extra range per tank might actually be more important!

So you get more power, more torque and better performance + 22% better fuel economy from the 335d.

That sounds quite good.
