Hi

I'm new to this board and I hope you all don't mind me jumping in on it only very occasionally. I don't get much time to "surf". I have a few questions about my new BM that I'd like to pick your collective brains about.

I've just bought a 6 month old 330d M Sport saloon. Whilst the drive is amazing (had Y reg 330d before this), the expected fuel economy is NOT. I was told in the showroom and told during my test drive that it came with Efficient Dynamics, but I am seriously doubting this fact by the fuel consumption. It's doing 34 MPG on 28 mile, steady dual carriageway, speed of 65-70 steady. My old car did 46-48 on this run!

Big question - did ED come as standard on M sport models registered in June of 2008 (and if not, when did it come in )? And the next question - if it sounds like my car should have ED, what on earth could be wrong it?

If it doesn't have ED, does anyone know what combined MPG should be for the M Sport model, as there's no mention of it in the brochure.

Any help much appreciated. Thanks

Sounds about right in my experience if it's an auto. Had two e46 330d sport autos that would average around 33 weekly which included 20 miles of dual carriageway each way commute. They only ever got to average 40 on a long run. Our 335d is marginally better (non ed).

The quoted mpg figures are always way off what you achieve in the real world. Am sure the mpg will improve with time, I know it did on my previous BMW diesels. Take comfort in the fact you are probably not far off what the 4 cylinder diesels achieve and yet you have the arguably the best performance and diesel engine in that car segment.

Not sure on the ED stuff. If it was built (not registered) after week 12 2008 then I am sure it will have some if not all of the features. I note from the BMW site that the 330d doesn't have auto start-stop, but again IME it's a pain in the arse as when the car switches itself off the air-con also goes off.

I've got basicaly the same car but a touring. My drive to work is 14 miles but my trip comp says I'm only averaging 19mph!! MPG is steady at 28mpg so I get around 300mile+ per tank. The ED issue you have seems to stem from the Sales person maybe not explaining which ED technology you have on your car. The term covers a broad range of technology ranging from light weight engineering to brake energy regeneration. They include electric power steering and the cars ability to close the vents in the grille to improve aerodynamics. Any one of these options may not be able to claim that they have a direct effect on fuel economy but they can all have a positive effect on lightening the engines workload and thus helping it run more efficiently.

I only have the humble 320D M sport Touring and my fuel consumption is nothing like that quoted.

The cold weather has a serious affect on diesel engines , and it can be argued that 20 miles is the minimum required to fully warm it up, and achieve reasonable fuel consumption.

a friend of mine has an older (2004) version of the 320D and he constantly gets in excess of 10mpg more than me and our driving is not that much different?????

There is a lot of discussion on the BMW sites regarding fuel consumption, maybe worth a look

This sounds wrong. On a 100 mile motorway journey in cold weather a couple of weeks ago, I averaged 40mpg on the the computer in my ED 335d touring. That included the 5 miles pootling at 30-40mph in a stone-cold car to get to the motorway, when I can see from the journey computer that the economy goes down to low 20s. Economy improves a lot with a few thousand miles on the engine, but since you said your 330d is 6 months old, I would have expected better.

I'd keep a log of mileage, fill-up volume and type of driving for a couple of weeks, that way if it's still bad you have something documented to talk about with a dealer.

Edited to add: mine is a November 2007-built "58" and definitely has the ED features, which seem to consist of decoupling the alternator when the engine is under load on the 6 cylinder diesels.

Thanks once again everyone for your help.
I have now ascertained that this IS the model with ED (Oct 07 build) and should have combined of 45 mpg! I'm getting 40 on a long run with no stops and starts.
Does anyone know what speed I have to be driving constantly at to get the best mpg?

It does take a while for diesels to run in and produce better economy. My fathers e class was averaging about 8mpg more when he sold it @ 80,000 miles than when it was new.
You'll be lucky to get more than mid to high 30s from the 3.0 diesel auto in mixed driving. A gentle run can produce 45, but I expect that most people on PH get bored driving that conservatively.
My 320d can get 54mpg, but 90% of the time the trip computer sits between 37 and 43....

I def get bored driving in traffic and often spend time with the lever pushed over to the left and drag racing between lights or playing with the paddle change on the steering!!! driving

Official figures are getting more and more far fetched as cars get heavier and heavier.
They are done on a rolling road where the cars own weight is not taken into account, and this is what really makes a car drink.

I got 38mpg from an ED 320d auto touring up till 12k miles, then it was just under 40mpg.

I take it your old 330d was a manual??


A good friend of mine was a sales guy for BMW and he went from a 330d to the new 272 330i and he got an average of 34mpg from both cars. I was amazed that I got 38mpg from a 330i over 2 days and 500 miles and he was saying that the latest petrols now seemed cheaper to run that the diesels.

September saw the new aluminum block 330d arrive which is meant to increase mpg quite considerably, near rear lights etc.
Have you got this one or the older one??

Forget that, just realised you said yours was sept 07 build. This means it is an ED car but using the older engine.

What we need is a sticky thread with a means of voting on ave fuel consumption for BMWs.

Agree that current figures are way out.

I recently drove a Mini Cooper D for a few weeks. Best MPG was around 43, quoted is in the 70s.
My old M3 got 25mpg no matter how I drove it.
Current X5 X35D averaging about 29

Yes, my old car was a manual. But it didn't have ED! I was told that for the new new engine, the only difference was that the emissions were a bit lower and therefore in a lower Tax band (D instead of E)

Your info is very helpful. Thanks

I bought a 330d m sport last week, on the return journey home of 200 miles computer showed 52mpg and I used 1/4 of a tank with a range of 680 miles on the tank , my Mrs has used the car all week and she kills my fuel economy on the school run , anyway over the week the average has come out at 42.8. smile

Ps. mine is a manual, had a 335d auto previous and that was always 28s round the town and around 350 miles per tank 400 on a good week and best ever was 580 miles over 18 months of ownership , that was pretty good on a run best ever was 46 on a very steady run down the A1.

Thanks Jeffc.
I know auto transmission eats diesel more than manual, but that's an incredible difference to my car.
Dealer tried to fob me off today saying that the indicated consumptions on the sales brochures are "done by the Govt and they have to use them" Yeah right - they really just hate using such inflated figures to sell their cars!!
Your car, although it does far more than mine, still does about 6/7 mpg less than the advertised mpg.

I'm going to start a "sticky thread", (whatever that is - I'll just guess).

E46 330d 53 M sport Auto 114k, M1 J31 - J41 5 days a week. Average around 33 MPG. This includes "spirited" driving. If I really do behave then I can easily expect 37 38 mpg.

My 2006 330i M Sport would almost do 34 MPG at that speed. Have you checked in the iDrive that it's not set to US gallons?

As the OP says it could be set incorrectly in the Idrive - however ignore the OBC and just do the basic maths, fill the tank up and then you have the cost per mile & also you can calculate the MPG from that.

Try keeping it around the engine speed at which peak torque is achieved - On my 120d most of my hourney to work is at around 1500-2000 rpm.

I regularly see 44-46 mpg (measured not computer)

Out of interest, do you know what the computer says?

Our 320D Touring (manual, pre ED) is showing 37mpg on the computer but I'm sure it's doing better than that (mind you, it's only done 8k miles so the engine hasn't loosened up yet).
