I noticed that the 2008 cars having lower co2 and better MPG. Are there any other changes?

In the real world i expect about 35/36mpg from the pre-ED e92 335d. Is the ED model likely to improve on this in the real world.... combined cycle.

[ghosty]

hey, i think i read that the ED models start from the 57 plate. they did some cleaning up on the engibe to make it more efficient and cleaner but no power changes

from what i remember the only differnce for the 335d is the addition of electronic brake distribution cos of the auto box the stop/start doesnt apply

cheers ghosty

Couldn't find anything other than the trickery to increase mpg and lower co2.

So i'm not missing much if i go for an 07 model. ED just saves me 60 quid on tax a year i think.... and about 700 quid on fuel over 3 years. So not that much in it.

Only found 1 guy posting on mpg, going from 535 pre-ed to ed version. Claims 4-5mpg increase on average. Thats impressive if true. Nearly 40mpg tank avg... seems v.high for such a powerful car.

[ghosty]

briers, theres not really much in really.

road tax for the ED is £200 (177g/km) vs £235 (200g/km) for the non-ED
the book figure for comsumption is 4-5mpg gain on the combined. so not a huge difference at all.

i was also actually comparing the 'd' to the 'i' since the ED 'i' claimed a combined of 31mpg which is pretty amazing for what it is. and i think the 'i' can be had for a bit less than the 'd' so the difference could go to paying for extra fuel/road tax. but i do too many miles in order to make the 'i' a viable option, but just think of the smiles per hour though

i found the link from the article that i was referring too:

EfficientDynamics measures on the BMW 3 Series:
- Brake Energy Regeneration: standard on all 3 Series models.
- Auto Start-Stop: standard on all manual transmission, four-cylinder petrol and diesel 3 Series models.
- Optimum gear shift indicator: standard on all manual transmission 3 Series models.
- Electric Power Steering: standard on all 3 Series models, except 335i and 335d.
- Active aerodynamics: standard on all 3 Series models, except 335i and 335d.

Has anyone else had experience of driving a pre-ED and post ED 335d.

I know it's a boring question but i'm interested to know what the combined MPG increase might be between the two.

Then i can see if it's worth paying a little bit more for the ED if it saves on my fuel bills over 3 years.


Cheers

Says under your name you already have a 335d.

When signing up I had to choose a car to continue

I reckon that 31mpg is just about possible in the 335i, but if you drive it with any enthusiasm it tails off incredibly quickly.

I've discovered around town that you really need to get into the high gears incredibly quickly. Works well, but feels odd.

Yesterday I accelerated up to 30 in 1st gear, then dropped it straight into 6th gear to coast along in lean burn mode. Odd

the mpg stated on the ED 'i' is a lie!

it says my car will do 36mpg combined. Like %h!t it does, im lucky to get 22mpg and 2 bmw dealers told me thats normal

Id imagine diesels doing close to the figures though.

Other things about ED i can remember is that on manual cars, it tells which gear is optimal for the speed/rev you are doing (for best consumption) + auto start/stop.

This is a pet hate of mine..... sorry to waffle on...

Remember that when they claim extra mpg or lower CO2 it doesn't mean 'in the real world', it means they've found a new way to 'fiddle' the standard 'test' to get better results often with the same car, just quoting some daft add-ons like 'self closing grill flaps' as a disguise, when really its about test technique and tailoring the car just for the test, not the road.

Unless you drive like the standard 'test' you've got no chance. The test is slow speed, gentle acceleration and using very low revs, that's why it suits diesels better and thats why you're more likely to match the test results in a diesel rather than a petrol.

Auto's were gaining an advantage as the rules said they could change gear when they want thus being most efficient, but manuals had fixed shift points - yaris or lamborghini still had to change from 1st to 2nd at 9mph - then they invented 'gear shift indicators' which the rules then allowed manuals to be shifted when the car wanted, so in a stroke manual cars suddenly did more mpg, through no other changes but because the test could now use revs appropriate for the engine.

But any buyer driving in the same manner would notice no difference between the two cars, even though the one with shift indicators mysteriously does more mpg under the test!!

That's why hybrids do well cos they are allowed the start the test fully charged and the whole test (urban and extra urban) is only 20 minutes long, so they can do all but the higher speed stuff on battery power - zero consumption!!! Genius.

Also the 'combined' test is not a test, it's just the average of the urban and extra urban, so where car is poor at the urban (large engine lets say) they can fit a 7th or 8th gear to make it do better on the extra urban and suddenly the combined figure goes up - Genius!! And what figure is the one most touted and most relied upon?? Combined of course!!

It's all smoke and mirrors - but its going to be changed in 2012 - see what happens then!

Cheers - i understand the MPG debate; with regards to rolling road testing.

I know official figures are unachievable in most cases.

Despite the official figure being something like 38 on an 07 335d i'm realistically expecting 33-35.

My question was really if anyone has driven both and whether that average combined is likely to rise with an ED car. From what you say it's just a fiddle?


At very least someone with an ED 335d to give their tank combined.

whats happening in 2012?

[doughboy]

Apparently the international fuel consumption test is in for review in 2012 - so they'll be making a new one to base MPG / CO2 etc figures on worldwide instead of the current rather laughable test.

It will be more onerous for larger combustion engines for sure, favouring hybrids and alternative fuels.

But if that makes manufacturers develop light, fun, sporty and eco friendly cars then I say bring it on!!

awesome

for my 335D ED - with a fair bit of motorway driving at brisk speeds....the OBC says 36.2 MPG.... getting around 480 miles out of a tank, could probably go over 500 if I let the tank go right down to empty.....

Interesting.

I'm getting around 400 out of a tank on my 335i

Not a massive difference.

[briers]

And i must say, the pre-ED 335d's i've driven have been around 35 and 36mpg too.

Blimey,

How many 'miles to go' on the OBD by then?

-100?

If I just do town driving I'll get around 300 to a tank. Add in motorways and it will rise to 400 or so.

I've really changed my driving style round town, which is making a big difference. If you remember to drop it into 6th gear at 35mph then you will see 30+mpg compared to 20mpg in 4th at the same speed.

me again
i got 500 miles out of my first full tank with the computer saying another 45 miles left. but those figures gone out the window as its the weekend and ive been playing

Remember the 335d is automatic only. So for a fair comparison it should be against a 335i automatic as well.

I never go above 3rd in town... helps keep the speed to around 35, any faster and you can 'feel' it.

6th?? must be at idle doing 30mph?
