However both the loaner F34 (2.0l diesel) and this car are terrible on my works run – with all other cars, except a Ford Fiesta diesel (consistently 3 mpg off the mark), I have managed to get the combined mpg rating. Regardless of how hard I try, the F30 335D only returns 42-44mpg.
I can only put the mediocre consumption down to the kerb weight (1705kg), the hills and the fact that the engine is only fully warm at the end of the works journey.
The combined and extra urban figure is calculated using an average speed of 39mph with a car already up to temperature and ambient temps of 21ºc.I can only put the mediocre consumption down to the kerb weight (1705kg), the hills and the fact that the engine is only fully warm at the end of the works journey.
The problem with that is unless you do 33mph every where (the 39 average is worked out by accelerating to 70 and then slowing to 33mph for some 4 miles to hit the 39 average) you can expect the official figures, you may be lucky and get them, but more often than not cars are geared for the official figures not for sitting at 70 or 80mph.
This is why if mpg is important you need to test the cars you are looking at doing the runs you are doing.
People say the official test is a good way to compare difference between cars if not the real world mpg, that is so wrong.

For all the cars I have had I've achieved frequently (or bettered) the combined.

Where and how you drive make a big difference
However I filled up yesterday @ £0.999/ltr (16p off per ltr at Tesco with the £1.159 diesel price) so I'm pretty pleased

Absolutely, but you are buying cars that suit your driving. Where and how you drive make a big difference
Someone who sits at 90 every day for an hour on the M1 would be an idiot to buy a Toyota Aygo to do it in, even if it says a combined of 76mpg, because at 90mph that car is struggling to get over 30mpg.
Not many cars allow me to get much passed the Urban figure, that is because I am doing sub 5 mile journeys or when doing longer runs I sit at quite high speeds.

What does this engine sound like from the outside? Does it still sound like a diesel? I don't want to go back to diesel, but the used car market is flooded with them and it is very difficult to find anything desirable with a good petrol engine.
It sounds like a very good diesel - not much clatter or dagadagadaga A petrol 335i would certainly sound better. However you choose a car for what you need it to do a commuting in comfort a family car or a weekend car. A do it all car mid life crisis car dream car etc.
Once you choose that then it matters not what it sounds like as its purpose is clear.

Re sound... after my 2ltr BMW Derv my 3ltr Derv is positively C63 Like,
Seriously ,totally different sound quite pleasing really
For sure the I6 is hugely nicer sounding to an I4 to the point its quite nice but a nice sports petrol on the other hand is way ahead Seriously ,totally different sound quite pleasing really
Ie I looked forward to starting up my RS6 actually opening up all the windows to enjoy it I've never nor will I ever do that to a diesel.

It's not bad for a diesel.
I like mine but the fact I'd swap it for a 535i tomorrow if the right one came up says it all IMHO.
Just got back from a 1200 mile trip to Germany - averaged 42mpg which IMHO just isn't that impressive to justify the dieselness.
Kind of depends doesn't it what would the 530i F10 have achieved on same trip?I like mine but the fact I'd swap it for a 535i tomorrow if the right one came up says it all IMHO.

No idea but my E39 530i did 35mpg on it's last jaunt to Europe.One thing that confused me was that for large sections of Belgium and Netherlands I couldn't get it to average more than about 40ish at a constant 70mph. Once back in the UK it happily did almost 50mpg at the same speed. Bizarre.
Both directions too. Undoubtedly contributed to the low average.

550i apparently gets around 34mpg doing a long run sat at 80mph, guy down the road went from 535d to 550i. I think the 535i would be around 37/38mpg doing that sort of run. I took a touring out and it seemed to get that quite easily when resetting it and sitting at 80, was over 40 at one point.
I used to get around 36/37 on a pretty quick run in my 335i auto touring, that is the old gearbox as well.
My 535d touring I had before it used to slightly worse at around 35/36 over the same journeys.
So I don't think the 535i would be much less than 535d.

If only they were about. Cheapest half decent one on the AUC site is £20k for a 65k mile 5 year old one. Bonkers money, why are 5 year old high mileage examples so much!? It's a 5 Series not an M5..Don't the M5's do 28-30mpg...580bhp what's not to like?

Is that code for "sorry I was wrong" 
No, it's not. I wasn't sure what the legal requirement was (hence the question) but it still doesn't sound ideal. Isn't the recommendation that the trailer not exceed 85% of the towing vehicle curb weight? That figure keeps popping up when reading up.Either way if you routinely tow 1.8 tonne trailers then a 3 Series doesn't sound like the ideal towcar it's being portrayed to be. I thought it was vehicle weight rather than outright power that was most important with towing?
BTW many cars can tow more than their own weight your 85% figure is way off the mark or in other words wrong.
As an example a Touareg can tow 3.5T, 1 tonne more than its weight.

Because they're scarcer than unicorn jizz that's why. They probably figure there's a small band of petrolistas who wouldn't run a derv tractor for love nor money. And they're probably right. To my ears, the 335d sounds terrible from outside - not much less tractorish than a 4 cyl diesel. But it sounds OK on the inside and is much less rattly and unrefined than the BMW 4 cyl diesels.
On internal sound alone, there's not much worse about a 6 cyl diesel than a 4 cyl petrol. A petrol 6 or 8 will be in a different league, but will also burn a fair amount more fuel (assuming that you care about that, which fewer people should, in my view).

I see your garage you've not owned either an I4 or I6 diesel so comments must be from relative or friends owners not personal ownership.

Certainly the I4 sounds notably worse than the I6 and cannot be compared to a nice I6 or v8 pertrol. You'd never go outside to start a I4 or I6 or v8 diesel purely for the pleasure of doing so ditto reving it when stationary - whereas say an RS6 you'd do every day which is what I did.
So totally accept the sound but I have to add the I4 is rough whereas the I6 is pretty good for what it is sound wise- you'll never get away from the diesel (or turbine noise) so make the choice.
