I'm not familiar with the route you describe and I don't own an M135i so difficult to say what mpg one of those would achieve in the same circumstances; 24 sounds low to me but if I offered an alternative I too would be guessing!

What I do know is that I've owned a couple of diesels and monitored their fuel consumption over thousands of miles (and that was done the old fashioned way and not just off the trip computer); I've also done the same with petrols and my conclusion is that diesels miss their claimed numbers by more than the petrols. I think the published figures show a new 120d auto to be around 26mpg better than an M135i auto but in practice I'd be very surprised if the difference was as much as that. Based on experience with my 123d and 335i I reckon I'd get about 53 out of the 120d and 34 out of the M135i and for me the M135i would be worth every penny of that extra fuel cost! wink

Almost on a daily basis I tend to notice people in golf bluemotions thrashing the life out of them in the outside lane 6 inches behind the next person, and 330ci's in the inside lane doing a steady 60.. Is this a case of having the power but not able to afford the fuel to use it?

I'd imagine some diesels will be lower mpg than quoted as some people tend to drive them faster due to the extra economy you're getting.

I was the opposite I used to lazily mooch around in my old vag dsg diesel average 49mpg, same route to work in Z4 3.0si I see 27, but it's a much more enjoyable drive smile

I've covered 5000 miles from new and never re-set the trip. It's showing 35.8 MPG

I went for ..

Silver 3 door

Red leather, heated, full electric

Adaptive dampers(a must IMO)

8 speed auto (a must IMO)

Adaptive xenon's which turn with the steering and have high beam assist.The turn element is very good, but the high beam assist is too slow to react.

Pro nav. expensive but very god.
Comfort pack.(Folding and auto dipping mirrors) N/S mirror dips when reverse is selected, good for avoiding scuffed alloys.

Different engine, 3.0 N52, but in keeping with the theme, I seem to get better economy the harder I drive it.

Seriously Id love the Man Maths to work out re Petrol v Diesel ,Im just not convinced that driving like you should In a car like that for many motorway miles that I do , would get you mid thirties MPG.

...and as another poster said I also see many big petrols in the middle lane and I dont buy this "well they dont need to" schtick. I would love to be proven wrong mind.

The M135i only gets good mgp on the highway, you need the engage 8th gear to see good results. If you need a frugal car the M135i is probably not the car for you, driving around town 17-19mpg is the norm.
What's a "Highway"?

I've driven a mixed 5000 miles of town, motorway and A+B roads from new and my car will select top gear 8th on A&B roads

Totally disagree with that. My experience with diesels (both BMW's) is that you can't get anywhere near the combined figure unless you drive like a granny and that applies even on a long run; in contrast, a petrol will hit the combined figure on a run without trying to drive for economy. There was a thread on here on the same subject a little while back and, while you'll always get the occasional 335d owner who reckons he gets 40mpg at a steady 120mph, the consensus was that diesels tend to fall short of their claimed fuel consumption figures by rather more than their petrol equivalents. They're still more economical in absolute terms of course but in my experience their advantage isn't as much as the published figures would have you believe!
+1, in my experience, although I don't think it's so much a diesel/petrol thing as NA vs turbo: with turbo engines, the manufacturer may have lots more freedom to program them to perform to generate spurious results on the EU fuel cycle. In the two cases where I've remapped my diesels, I've not only achieved more power/torque but much better real-world fuel consumption. My older (07) X5 30D would get to 90% of the claimed figure and 109% after remap. My current 40D (stock map) doesn't get better than 80% of the - on paper - much improved figure. I put that down to BMW getting better at playing the numbers. Haven't had the 40D remapped yet for comparison. My E87 123D went from averaging 70% of the claimed combined to 80% after a remap.

Both NA petrol engine cars I've had in recent years - both sixes, one a BMW, have averaged 90-94% of the manufacturers' claims, with the combined figure being readily achievable on longish runs. I haven't had a petrol turbo to see if the claims are as inflated as they are for current turbodiesels.

So how should you drive on a motorway in a car like an M135i? I'd actually say no different from how you'd drive a 120d most of the time because to me motorway driving is cruising in the 80's if you want to keep your licence. The only times I'd use the extra urge of an M135i would be to pick a gap to get into when I was joining from a slip road or using the acceleration to avoid getting boxed-in. Driven that way I'd be pretty confident of seeing mid-30's on motorway running but the real plus would be to have a car in which I could have far more fun when the opportunity presented itself on A and B roads.

Apologies if I'm misinterpreting what you're saying but it almost seems like you're suggesting that unless you drive a performance petrol car like you stole it all the time you're somehow not driving it properly? Personally I just don't see that and if you applied the logic to M3's, M5's, C63's, etc, their drivers would be forever being detained at Her Majesty's pleasure!

No no no JN.smile Youve hit the spot I am allways curious about and never seems to get mentioned. Mid eighties in a powerful petrol.
Ive seen many posts from "big" petrol owners saying "...and on the motorway cruising in the middle lane I can actually achieve x mpg ,"

I once tested my little 120 D auto 177bhp one night on the M4 at 80mph for 10 miles I achieved 47mpg at 70 for 10 miles I achieved 56mpg and for 15 miles at 55-60mph(couldnt keep constant re lorries) I achieved a crazy 72 mpg.


So I really am interested in what a powerful petrol would do for many miles at 80-85mph.But ive never ever seen a post on any forum that gives that.

On a tangent a 7 mile journey in london which took 35 mins got me 21mpg!!

I'm afraid I only keep a track of total mpg! However, when I drive on a motorway (not a huge proportion of my driving) I tend to cruise in the 80's and overall my 335i is about 10% down on the claimed combined figure at just over 30mpg. I can see from the range between fill-ups that short runs and stop-start driving around town have a marked adverse affect so my conclusion is that the other driving - which includes motorways - is averaging more than 30mpg while the short runs and stop-start stuff is averaging less. Sorry I can't be more precise but when I'm on a relatively quiet stretch of motorway I'll reset the trip, set the cruise control at between 80 and 85 and see what the mpg looks like after 10 miles or so!

However, the point I was making was that in exactly the same situation with the same driver my diesels were much worse in terms of shortfall from their claimed figures; my 123d was around 17% down and even taking it relatively easy on a long run I could never get it over 50mpg. In contrast, I've had several tanks in the 335i where it's pretty much hit the combined figure and if I was doing more motorway work I think the overall average would be sitting at closer to 32mpg. An M135i auto is meant to be around 4mpg better than a 335i and hence I do believe mid-30's would be achievable from one of those if you do a fair proportion of motorway running.

Interesting and I think you may have a point here! My 335i is much closer to its combined figure than things like my old 123d but nevertheless it's still down; however, my old M3 CS almost always improved on its combined figure in similar circumstances. With a bit of man maths I can see this stacking-up as a compelling case for buying an E92 M3 or perhaps even a C63! smile

All of our companies 320d's and 520d's has had there fuel consumption ruined with around the country lanes type driving. Because modern diesels produce peak boost at just above idle RPM. constant throttle and even road speed is where they look best.

Our 335d has long term averaged 30ish mpg but the wife got over 40 the tour day to Taunton and back! I've never got near that!
Hoping the M135i isn't too bad. A month to go...!

That's *exactly* the man math argument that has me using my 911 rather than the diesel DD for every possible journey, as it gets 94% of it's advertised mpg versus 80% AND the juice is 8p/litre cheaper. Works for me… laugh

I have to make it clear that with an M135i. Unless you are sitting on a motorway for all your driving or you drive everywhere at 40mph you will not average mid 30's.
It's a 3.0T and if you are concerned about Mpg you really should look elsewhere - whilst it can achieve mid 30s on a long run this should be seen as a bonus. As as if you like to use your right foot at all it will immediately sink into the 20s. Then a hard foot will put you down to low 20s with no issue at all.
Then on a proper hoon you can see 15-20!

Highest I've had is 33mpg on a 240 mile dual carriage way/M'way trip sitting at 80 odd. The lowest is 13mpg on a PH hoon with some tasty kit.

If you want consistent 38mpg or more then you need to be looking elsewhere.

Although I don't think it was your intention I think you've actually confirmed what I and one or two others have been saying! The question Smashy raised was what sort of mpg he could expect doing a high proportion of motorway driving and your comment above suggests that in those circumstances mid-30's is indeed achievable. However, I don't think anyone has ever claimed that a consistent 38mpg or more is realistic and if that's your goal I totally agree that you need to look elsewhere.

The mpg an individual will achieve will obviously depend on driving conditions and driving style. However, I certainly use the performance of my 335i when safe to do so and across 22k miles it's averaged just over 30mpg; given the relative published figures I don't understand why an M135i wouldn't be capable of improving on that?

ETA:
I suspect EVO's long-term test M135i won't exactly have been spared the beans during its time with the magazine (to put it mildly). However, despite that it averaged 30.4mpg over almost 13k miles which suggests you can enjoy the performance and reasonably expect fuel consumption starting with a 3. I do accept that mpg isn't the main reason for buying one of these but not many people can afford to ignore running costs completely and IMO the M135i offers a pretty good combination of performance and (relative) economy.
