Are you averaging on the right side of 30mpg overall so far?

Sorry..... I thought you were joking.

Kanye reference? Tbf I'd probably take the 340i but like the idea of some economy with the 335.

I've managed 31.7 mpg on my 335i over 9000 miles and 10 months. Best I saw was just over 42mpg after long sections of 50mph limits on the M1. Worst is about 22mpg after some thrashing around back roads after getting stuck in traffic. I'm typing this at the airport and a journey of about 85 miles from home at speeds between 80 and 95 delivered me 33.5mpg.

Personally, I'm very happy with this sort of consumption. It's more than a diesel for sure, but it ain't a million miles away. I would think the 340i would do a little better.

Ok that's good to know, will be perfectly happy if I get that kind of consumption.

i have to say it always impresses me that a 335i can do 40mpg plus on a motorway even around 70mph cruise. with the great M3 roadworks an 50mph limit its even higher

Mine's not due until mid-December

Not really fussed about the mpg tbh. Assuming I'm getting around 40mpg in the 328i and the 340i will average 30mpg then 12,000m a year works out around an extra £500 a year on fuel I reckon... (and I'll get a chunk of that back in expenses)

Small price to pay for being able to enjoy the last remaining 6 pot petrol F30 before the nanny state has us all driving battery-powered roller skates.

[Ice Man]

Not that I bought it for the economy but 2k miles in I'm nowhere near these kind of numbers in my 435i . Averaging mid20's have seen very high 30's on a long motorway run. My M135 was good even pressed hard it would return ok mpg. Where as a good play of the loud pedal on the 435 you can almost see the fuel guage go down

[Richtw]

I am the same 428i and I am getting about 31mpg on 7000 miles - if I push it I am high 20s, very steady on the motorway then about 35... I think I may need to ease up ;0 - or trade up to 6 cylinders as they seem much more economical.....

We are back to drivers, use and driving conditions aren't we?

I'm in the "over 30mpg" camp for my 535i Touring (30.8mpg over 22,000 miles). My conditions are quite light and often my progress is governed by the road speeds of others. The 535i will return over 35mpg at motorway speeds.

You mention the 6-cylinder engines seem to be much more economical. That is very close to the true picture, if you drive the smaller engine quite hard. Noted by users over the pond in the US, where many have driven the 328i and 335i. If you drive the 328i near the limits, the 335i at the same pace is just as economical, only when you use the extra performance of the 335i do you use more fuel, as you'd expect.

Where the 328i will score is if you drive light, then the benefit of the smaller engine will show.

Good point. Not that I'm using this as the most scientific test but Top Gear once had one of the smaller 'economical' cars around the test track and had a high performance car behind it. The economical car was driven hard around the track and the high performance model was told to just keep up with it. Fuel economy was then compared

Results? Economical car was worse off than the high performance model, as economical car was driven at 9/10 whereas the performance car was at barely 4/10.

This was obviously done by the TG crew to feed the petrol-heads desire for bigger engines. Someone will post a link of the video I'm sure.

EDIT: Quick google tells me it was Season 11, Episode 1 - https://en.wikipedia.org/wiki/Top_Gear_(series_11)

After Clarkson is criticized for using supercars to discuss fuel economy with, he is told to do another test. Using a Toyota Prius and a BMW M3, he has both drive around for ten laps of the test track, with the Prius driven at maximum speed. The Prius is revealed to have managed 17.2 miles per imperial gallon (16.4 L/100 km), while the M3 (which matches the Prius' speed) is able to achieve 19.4 miles per imperial gallon (14.6 L/100 km) with its 4.0 L V8 engine. Clarkson declares that it doesn't matter what you drive, but how you drive it.

your argument seem sound enough to me, it is costing you money by not changing I would get your order in now.............

So how are our 340 owners enjoying their cars. Maybe some have now run in the engines, so how is the performance now?

Also, mpg - should be getting a rough indication of expected mpg now? I know mine has got steadily better as the engine beds in but what is the 340 delivering mpg wise?

Still working away on my man maths so any info helps!

Frazzle I'd seriously look at the 340i and 335d only which I think you might be. I'd say that unless you frequently have the chance to track them the M3 is overkill and you're only getting it for the 'look'. Just some honest personal feedback, for uk roads it's about 2-3 seconds of acceleration only at a time!

If you have a 335i currently I guess your mileage must be manageable for petrol so it must surely be the 340i unless there's a compelling negative for that engine or your circumstances have changed.

Nice choice to be making though, which top of the range 6cyl BMW shall I own next yeah!

Not sure if it helps the man maths, but fuelly only has figures for one 340i, with a second just registered. Both are forum members here.

http://www.fuelly.com/car/bmw/340i

It looks pretty similar to the 335i on the limited data we have so far.

Thanks. Its the M135 that I have at the moment. My commute is mostly motorway so for the man maths to work I need the car to be half decent in terms of mpg on motorways.

The 335d is therefore looking increasingly tempting, and while I would miss the noise of the petrol, the only thing that really bothers me from what I've read is the handling of the 335d.

For the 340, it would be a 340 touring which would really be attractive to me from a family space point of view, but it would need to get mid 30s on a motorway cruise.

The handling seems to be more of an issue on pre LCI 335d's.
Owners that have 335d LCI's have not particularly reported any issues with handling.


You can always go down the ACS springs like most of us have if you are that fussed ... and keep your warranty intact.

First thoughts (bearing in mind I've had the car less that a week and have only covered 300 miles)...

Ride - On the adaptive suspension the car is very composed. Coming from a 328i on stock suspension & 18" wheels, this car is actually more comfortable and seems to handle the rubbish roads round Sussex/Surrey much better. Not at all 'crashy' even in Sport. Overall I'd say it feels very planted and pretty well refined.

Noise - Engine noise is a pleasant burble and not at all intrusive at m/way speeds. Running 19" 442Ms with Goodyear Eagles and I reckon they're quieter than the 18" 398's + Potenza's on my last car. Could be that the sound deadening is better on the LCI?

MPG - What can I say... mid 40's on a long m/way run, spirited driving (although I'm keeping it under 4500rpm) hints at mid 30's? Don't do much town driving. Didn't buy this car for its mpg figures, but am pleasantly surprised.

Really can't say much about the performance yet as it's not run in, but there's no hesitation at all when you poke the throttle at any speed it just picks up and takes off!

Plan to write a few more words when I've run it in.

Good to see you're really enjoying it. I'd really appreciate a meet up once you've run it in (as I know you can't be far away as you got the car from Chandlers) as would be good to have a ride in the passenger seat - I'd love to see how the new handling and engine has changed things. You're more than welcome to have a drive in mine (you're insured).

I've got a daftly well sorted 335d but I can't help but want a petrol again. As has been said, a well set up 340i xDrive would be brilliant. My car doesn't owe me anything now so I can change if I want but I suppose my problem is will the M3 be worth changing for? My original issue with it was handling and traction but I now know this can be sorted with ACS setup and we've now got BMW's own M Performance and Competition Packages coming along with difference dampers.... Hmmmm... But is it worth £20k over the what seems like an excellent 340i and is that enough to be worth changing?

Glad I'm not the only one trying to work out what to do!! Being lent an MY16 M4 for a couple of days this week but I'd also like to get my hands on a 340i but so far no joy.

This is great thank you, just the kind of bone that those of us waiting for ours like to be thrown. Week or 2 from getting mine and ride quality was a slight worry so that's good to hear.

[alarustic]

My own car is a 335d. Last week I had to make a one way trip to Bristol over a few days. I hired a car for this booked as a C-Class (not my choice). When I turned up to collect it the guys said, 'you can have the Merc or there's a 340 if you want it?' How lucky is that?!

First thing noticed is the sound in comparison to mine.... it is just lovely! Quite quiet but lovely all the same. Whenever I had to stop at lights/traffic it was always the same procedure... radio off, windows down and wait to hear the engine fire up again.... magic! Don't think I'd ever get bored of that! It had proper m-sport suspension which of course was much better than the X-drive.

The mpg it returned was 29.8 over the 500 miles and would do 35 on the motorway no problem. This car had just 300 miles on it when collected, so not run in at all.

Of course the twin exhausts just top it off nicely!
