Have to admit, I'm mightily impressed with the MPG as reported by the onboard computer of my F31 330D M Sport.

After some 700 miles she's reporting around 43MPG.

I've come from a MB C250 Sport - getting around 38MPG - so already the BM is paying for itself in fuel savings!

And I have no doubt that this will improve over the coming weeks/months.

Whats your 330D MPG averaging out at ?

43mpg doesnt mean anything as it depends on how and where you are driving it. For example, if this is just around town, then that is a fantastic figure, but if its mainly on a good run, I'd expect a lot more.

I got 56mpg from my E90 last week going up a boring 50mph road following lorries, but I dont get that all the time.

Valid point I guess - but it means everything to me. The driving I'm doing in the 330D is the same as I was doing in my previous car. So like for like journeys, the BMW is coming out over 5MPG better on fuel already.

my oldcar E92 330i coupe was getting around 29 mpg .... my 330d about 39 mpg So I'm more than happy, doing a lot of sport / Sport+ mode driving though. But I live in a hilly area which allways criples MPG


Dunno if Eco pro really gives much more MPG or not, it does lower the revs and responsivness when you put the foot down ....

Good news, think it is down to the non fully functional indicators

I guess what I should have said is what percentage of driving do you do for around town vs on a run?

[HighlandPete]

Looks like we have an average of 41mpg, so far.

extra-urban driving, cruise control at 70 mph, 52 mpg over a 600 mile journey. Urban driving, mixed speeds etc 38 mpg. Mixed over a week 45 mpg......

Super happy, my previous E90 318i average was 30 mpg, best on a very careful run was 45 mpg.

My outgoing E91 averaged 39 mpg - if the new 330d M Sport will do 40+ i"ll be very happy, when I get it that is!!

I'm getting near on 39 mpg out of the 328i with an even mix of town/country lane/dual-carriageway driving. Mostly in Comfort but with sessions of Sport/+ when I haven't got SWMBO on board Also managed 50.9 mpg on a 300 mile motorway run.

Get the impression that I'd get +5mpg or more in the 330d with the same sort of driving.

Thats great fuel consumption from the 328i. Although I love the 330d, makes you wonder sometimes whether its worth £4200 more.

Edit: its £2600 more as you need to add a sport 'box to the 328i to be like for like. But even though, you would probably never get the fuel savings back.

[RobUK]

On paper the 0.3s advantage of the 330d in the 0-60 dash doesn't sound like much, but I suspect the in-gear midrange figures would be more telling. I get the impression though that the premium actually brings a much more 'relaxed' or should I say 'un-fussed' power delivery. The 328i is quick, but it's very busy - a bit like a sprinter. The 330d has that relentless diesel grunt - a bit like jumping out of a plane and just accelerating towards the ground!

Funny when you think about how 'relaxed' it is because for the driver it's really a psychological thing as the actual effort, i.e. flexing your right ankle, is about the same

Still, getting back on topic I can be jealous of you lot cos not only are you having a wee bit more fun, you're doing it using less gas!!

Anyone confirming the accuracy of the computer readouts with fuel logs?

One thing I notice about mine is that you only need apply 50% throttle to make good progress the majority of the time. No need to really floor it, especially around town (30/40/50 limits) as it too fast.
How about a fast petrol? Is this the same with how much throttle you need?
I haven't a clue as the biggest petrol engine I've driven was about 150bhp a few years ago now!!

From my experience, small petrol engines can feel as it they have a hole in the power delivery, hence why so many feel they need to rev them hard to get any performance. But times are changing, the petrol engine in the 328i gives us a clue to how engine power delivery is going. Let's also remember it is only a 4-pot 2.0-litre engine.

Power delivery is much better with the larger petrol engine. Once we move to the turbo petrol engines, we have much more low down and accessible torque. After all, the diesel's only have masses of torque because they are turbocharged. Some of us remember lethargic NA diesel engines, enough to put many off diesel altogether.

I 'back to back' tested the F10 530d with the 535i, of course they are different, and the diesel initially feels the more powerful engine, with its mid range shove. But for me the petrol was the engine of choice, very driveable, without having to use lots of revs. More like the petrol V8, has a very good mid range and such a wide power band.

I find my 535i is running very low revs in traffic, the 8-speed just keeps the revs in the 1,100 - 1,700rpm range on a very light throttle. I don't feel there is any lack at all. So very similar to the way a 3.0d diesel engine works in traffic.

We have so much choice these days, can pick the engine we like the best, particularly if we are not hung up on mpg (as the indicator of costs) or are controlled by BIK and CO2 emissions for tax reasons.

I know some are against the idea of BMW petrol engines being turbocharged, (must be NA to be a 'real' engine), but for me it just makes so much sense to get a more driveable engine for road use, just as diesel development with turbocharging proved. It is a key reason why so many love the diesel, even is real running costs are equal to, or even in the petrol's favour with many cars.

I went from the 540i 4.4-litre V8 to the 330d and the simplest description of different power delivery... the V8 when accelerating was a softer feel, the diesel had the harder edge, when you floored the loud pedal. The V8 was a faster car, just did it with refinement, so felt slower. A 535d was a similar performance to the V8, but so unrefined by comparison, when I tested them while owning the 540i.

When I picked up my 535i, the final words from the sales guy. "Just watch the speed, the delivery is very deceptive". That just about sums it up, refinement can dull the feeling of get up and go.

I have covered 1200 miles from new in the Luxury touring 328i on loan from BMW, it has given 36MPG overall some town work and mostly open roads never going over 77MPH but for the odd burst, this is good for a petrol but it needs REVS to go anywhere, and that just eats fuel then, the 330D touring M Sport I had for a day returned 53MPG on average cruise mode with the odd burst, so miles better on my journeys.

Is that on the computer or from fuel fills?

Brim to brim mate. but booting this is not for me, no real torque and feelings of GO.

Must confess, I didn't chose my 330d on fuel economy. On recco of my sales guy, I tried 328i and 330d back to back. It' down to taste, but the 328i didn't have the grunt I'm used to. Like others have said here, you can get it to move, but you need to rev it pretty hard and it sounds, and feels, like it's trying hard.

Got into the 330d and laughed as soon as I gave it some gas. So much effortless grunt, so smooth and a pretty nice engine sound with it.

For me the extra MPG is a happy bonus, but I'd have had the 328i in a flash if it had floated my boat more. I agree - hard to justify cost difference between the two cars on basis of MPG. Has to be down to which you prefer.

Wish you could get the light-footed nippiness of the 328i in the 330d though 0 can't quite have your cake & eat it ... :-)

YES the "Grunt" is what I went for in the 330D, the 328i just needs thrashing to get going, personally not for me.

[oop north]

My first post - I have a 330D SE on test this week to see what I think - considering getting one. It's from BMW Fleet, arranged by my local dealer, done around 1500 miles in total from new

Re mpg, the trip showed an average of 44 over about 100 miles in total yesterday (it showed 37.9 when delivered to me, but don't know how many miels that was over). The driving consisted of an 80-mile round trip to Manchester, a couple of local runs round the lanes (I live on a farm, midway between two villages a few miles out of Preston, Lancs) collecting the kids from school, and a run into Preston yesterday evening. On a long run, with eco pro selected and in cruise at just over 70 indicated, there is no doubt that a figure of over 50 is possible.

Based on my experience of various other cars over similar travels, I'd say it will at the moment be roughly as economical as my current car, a Subaru Legacy Outback diesel. The country lanes don't do the mpg any favours (mid to high 30s indicated) - cruising at a steady speed, though, yields very good results.

Don't know what difference there is between real / brim to brim consumption and what the computer says.

Hi and Welcome 37 sounds about right for a demonstrator where a large percentage of the drive is with one's foot down I've heard of high 20s if you drive it like you stole it and into the 50s if you drive it like Miss Daisy
