Even on a long run when being gentle, I've never seen anything like 50mpg. I'd love to!

Can you carry out the test 70mph cruise control on and go for 5-10miles just to see what that delivers as there could be a fault.

Or what previous car did you have and on the same commutes what MPG did you get in them v combined

I just don't get how that can be the case when my old 231bhp auto 330d would do that on a 180mile drive at speed limits with cruise control on. The 6th gear is 1,750rpm whereas 8th is 1,100rpm plus its the much more efficient engine.

I think the main problem is my total inability to drive at 70 on a clear motorway!

yep.


Although if on an M way say you put cruise on for one hour 80mph to do the same distance at 70mph is only 8 odd minutes
If it were a constant 85 then at 70 it would take 12mins
If you held at constant 90 then its 17mins longer at 70.

As we've seen the pic that one owner can get deep into 60's mpg doing speed limit so that one hour/70miles has cost him £6.74 whereas if he drove at the 85 odd range and the mpg is 42mpg then that same distance would cost £10.3 53% more expense to save 12mins....

Or another way of looking at it pence per minute of driving if he did 70mph then it would cost him 11.2pence per minute whereas doing 85mph it would cost him 21.4 pence per minute.

As I have been flying aircraft for a living for a while, I tend to think of fuel use as being acceptable if it's less than a couple of tonnes an hour!

Had my 330d F31 for nearly 2000 miles now and overall average is 43mpg from new - not bad given the performance. I generally turn in around 50mpg going to work (little or no traffic) and doing same route home in traffic I get about 40. On a longer run from Loughborough to Heathrow on Easter Monday I got bang on 56mpg with a 55mph average speed. Came back late on Tuesday night this week and got 44mpg and 69mph...

Or another way of looking at it is why bother with a 335d or 330d if you're that concerned about fuel economy? Fine if you want to save a few quid - and take a bit longer to get places - by driving slower but surely most people who buy a 335d/330d do so with an intention of using the performance available regularly and reasonably often? I suspect those that fall into that category aren't getting 50mpg as a running average or anything like!

That's the crux of it though I had one and used its performance a lot most days if I achieved on average 38-42 (38 winter time) and official is 42 then the hooning must have been well over 100

I don't always drive like that, I was on my way to a meeting and making good time. Driving any faster would just get me a long wait in a car park so what's the point?

I think the point is, with the 330d you can get those sort of MPG figures if you want. You can also have a lot of fun in the car and obviously not get as good MPG. It's an incredibly versatile car.

It has been nominated/given the tag best real world car a number of times and also the accountants car as in its a great compromise for performance or and economy. Loved mine and I'd have another (though have a 335d itch first)

So why do none of the owners of F30/F31 335d's/330d's appear to be claiming anything like the sort of figures you're suggesting in normal driving? Around 45-47mpg seems to be the average for the 330d depending on whether its RWD or X-Drive and, whilst it's harder to gauge for 335d's (because there are fewer around), early 40's seems more like it with one of those. Still impressive figures for the performance on offer but nowhere near the published combined numbers; therefore, if you're saying you used the available performance in your E90 330d and also achieved the published combined figure as a running average I'd suggest you're the exception rather than the norm (in fact you're quite possibly unique!).

Have you really done 20k miles in your RS6 already? Your profile claims you have!

[Welshbeef]

About 8k - I'm using that tool to scope out what it will cost me to run it over a longer timeframe.
I update the profile frequently and try to keep it as accurate as possible - when ever I change cars it has its full and final costs/miles etc.

So far my biggest concern is that I'm running £0.33-0.39pence per mile on fuel alone.... Hence me looking at a brand new 335d and overall it being significantly cheaper.
As a comparator my old 330d achieved about £0.14-0.18 pence per mile usually 16ppm. Living the dream is great but it grates with high running costs (especially as say the 335d is actually quicker now) and that money could be spent on my kids instead.


I must say the 330d I had never sounded great it was ok its performance was good and economy for what it delivered very good - noise on the RS6 is something else its stunning starting it up is grin inducing, holding a gear through the whole rev range is epic though its really too quick for most roads M ways its no fun going fast but A and B roads it is however I've found all too often the speed and acceleration is simply too much and I have to back off. Its a beast of a car a joy to own and one is recommend to anyone better to have lived the dream no matter how long for its worth it. You'll look back and remember with fondness

Ok so today I had best part of 3 hour test drive in a F30 330d M Sport with M performance pack.

I wanted to test it beyond my hardest type of use to see exactly the worst possible mpg I would ever achieve. I hit 40 MPG, I would never drive it like that (I'd lose my licence) it was a superbly compliment machine very good brakes comfortable seats excellent auto box and the rwd handling brought a smile - in fact cross country (same route as I use my RS6 there were quite a few corners where it cornered harder than the RS6 with more confidence.

I did reset the trip for 20 mins of the drive at the end and to drive as I would normally no Eco pro just comfort and how I would drive day in day out 53mpg - no motorway on that element of the drive.

How posters here get low 40's all the time and not from being in congestion I don't get it you must be hooning all the time - as much as I like to drive hard I don't all the time.

This car had 1k miles on it.

If that is as good as the 330d is these days the 335d is going to be epic with 25-30% more power. What a machine and extended Bluetooth is a must . I think I'm sold on one really loved it - noise hmm its a I6 diesel much mixer than the I4 and nice when really nailing it M way its silent

The difference is probably down to the fact that you are selectively resetting the trip computer on a completely warm engine whereas most peoples real world usage involves cold starts which bring the average down.

I picked it up from the dealer at 8:30am it was stone cold so 40mpg was achieved in that situation.

I'll accept that the 50's mpg was when it was fully warmed up after 2odd hours driving. I did pull into a service station for a conscience stop and reset it at that point - if I was trying for economy as another has posted well into the 60's would be doable, fun? Well you have your extended Bluetooth to pass the time.

Tank to tank to tank over two years and 35,000 miles my e90 330d lci auto msport has averaged 45mpg, dipped below 40 only on one tank and been above 50 on two tanks. Most of my driving is fairly long distances. A town bound car would be lower but probably still easy upper 30's.

[Mattt]

Why do people keep posting up E90 MPG on a thread about F30's? They are very different cars, gearbox for one 8 vs 6 speed.

True but 45mpg over 35k miles of motoring is at least a genuine example of what can be achieved with a BMW diesel; probably not too far away from the combined figure for an E90 which may in turn suggest that the published figures for an F30/F31 aren't as cloud cuckoo land as I'd imagined. However, if that figure was achieved by doing long distances at relatively modest speeds that's probably best case scenario and not necessarily representative of what most diesel owners will get.

The F10 ones are so I can't see what would be so special about the F30 in that regard?
