It'll be quicker in real terms on longer journeys as you may get an extra 100 miles out of that bigger tank are you expecting similar mpg? it looks like it is on paper anyway... I would never of considered an X3 in the past (when I was doing the miles/needed the space ) but that one makes a lot of sense

When I had a X3 loaner a short while back in 2.0d form, the mpg was considerably less than my 330d, esp. baring in mind the considerable performance difference.
I was getting around 44mpg in the 330d at the time, but averaged 38mpg in the 2.0d X3. Whenever I've had a 320d on loan, it 's averaged ~48mpg on my journeys...
I really like the new X3, but it's tall form factor and extra weight will blunt fuel economy don't kid yourselves.. I would estimate that an X3 in M40d form would be around 30-34 mpg long term average....

Thanks for posting this...may be my next car ..one day...
Very closely priced the i\d...tough one to judge..I like the d for it's not Nm and mpg but the 40i has all the drama...hard one that.

I think it will be very close to the 335d mpg, and anyway my main problem with poor fuel economy is having to fill up more often, and the X3 has a 68 litre fuel tank!

I very much doubt it will be. I've had a 335D GT and a 335D Touring and they both averaged well over 40 mpg. Mrs R's X3 3.5D has averaged 34.4!!

The new X3 is lighter and has a more efficient engine than your wife's 35d, and I average 36 to 38 mpg in my 335d!

Just for the record, the current 330d and 335d is a N57:

the one in teastons M40d and the G30 (and G20 no doubt) is a B57:

Yep, all new engine, hence the extra 60NM torque!

Indeed. However, no idea why they only gave it a mere 7hp more.

Missed a trick there. All joking apart and based on the performance figures, if they gave it another 20-30hp more, it would have been a lot quicker than the M40i. And that wouldn't go down well.

They've no doubt pegged it back to keep the performance similar - given the d has a lot more torque.

13hp actually, old one was 313hp new one is 326hp

I should think it was to keep the emissions below 170 g/km as with the Runflats it just makes under at 169 although mine with the non-runflats is 172!

Ar yes you are correct about the power. I was going by those Wikipedia pages which state the B57D30 is 235 kW (315 hp) - which is not the same as your engine.

Yours is 240kW which is 326hp.

Oh yes it is a strong engine, the M340d is going to be one hell of a super saloon!

[Ronstein]

Still not sure where you're getting your info from. As far as I can see, the official figures are M4.0D (3.5D) Urban - 38.2 (42.2) - Extra Urban 48.7 (51.4) - Combined 44.1 (47.1).

The M40d figures are the new much stricter WLTP testing ones, so only being 3mpg off the 35d's old NEDC figures is very impressive!

Indeed, but would be good it they up'd the power for the M340d. Especially given the M340i is a verified 374hp output.

Thats quite a difference between the two if the M340d gets the 326hp engine given they were always quite similar in power before now.

[isleaiw1]

I guess the fuel consumption difference will depend on type of driving - if a lot is at higher constant speed then lack of aerodynamics will make a difference...

But console yourself that s few quid on fuel will be nothing compared to depreciation!

I am reckoning that with a few extras, that is looking like 5k down and 530 a month on 10k miles, over 600 on 20k mile terms...

...and the WLTP figure for an F31 335d is 44.8 (so under 1 mpg in it in theory) - hence why I'm assuming same driver same roads should get fairly similar results although obviously at higher speed where drag will come more in to play the difference will open out... But whatever it is in reality it is an impressive blend of go & mpg for those that do high mileage, need the space and want the performance... Not sure a smaller engine can really be compared as it reminds me of when Top Gear sent a Prius around a track flat out followed by an M3 (I think)...

Yes but it's improved the X3's 0-62 by half a second, so the M340d could be less than 4.3 0-62, so quicker than a manual F80 M3!

The 3.5D is pretty interesting, even more so if you stick it in Sport... doesn't drive like an SUV, it's an animal!! Lighter with more power will be VERY interesting. A friend has ordered one to replace an M4 GTS (growing family). Can't wait to get his views.

With the badging being so subtle on the 3.5D (just small wing badges) it's great fun tackling hot hatches that think they're going to leave you in the dust
