I doubt BMW will allow the M4 to accelerate slower than the diesel, Xdrive or otherwise. It will certainly need to be good though, especially with the likely lower running costs of the 435d by comparison.

I wonder if that'll force them to make the M4 four wheel drive only?

What turbos and 4x4 at the same time? The M beards will have a fit!

The rumour is they have targeted a kerb weight in and around the e46 M3 for the f30/32 M3/4 lots of talk of carbon fibre everything in terms of body panels,they won't get there with a 4x4 drive system as well.

Best guess I've seen is 1550kg and 430-450 bhp.

Yeah, the beards would think the sky was falling in if they did both. It will be interesting though, hopefully it means the M4 will be even more special this time around so it can stand well above the rest of the range. As for me, having had a 335d six years ago, I think I might return to BMW and give the 435d a whirl, ideal for lazy but fast progress.

I guess that would get it far enough into the low 4s to 60 to distinguish it from the faster "normal" versions in the minds of the stats obsessed.

Will they bring a large diesel x drive to the UK.

With the 3GT they only have petrol engines in the xdrives. Maybe to avoid stealing sales from the X range of cars.

Either way, it immediately made me click back to look at X6's.

Don't argue with people who don't get it, you'll never win.

I remember arguing with this with dbv535d or whatever he was called on the old 'make it so' and 'mapped' threads but he still didn't get it after about 50 pages

Just refer them to the wiki entry

If any M4 is going to be carbon fibre this that and the other and the last M3 was £50k then wtf is this thing going to cost? Depreciation will be of the epic variety.

I don't think they'll make anything important out of CFRP, probably just the body panels. Non-structural CFRP is not particularly expensive to produce because it doesn't have to be made particularly well, especially if you aren't trying to shave every last gram that you can off it.

BMW have already stated the don't envisage a full on M car with 4wd... The M4 will be RWD but future M cars who knows... There was a time when they said never to turbos but hear we are.

What about the X5M and X6M? If they're saying that they aren't real M-cars, I think they might upset a few of their buyers.

It's true though.

Of course it is, but I didn't expect BMW to admit that.

Lol... You said it not me. I was merely seperating cars from SUVs which of course you knew . Bored and sniffed out a morning wind up to colour your otherwise drab day perhaps?

When I was over there a couple of years ago at the M5 launch, one of the engineers told me they'd produced them for the Far East and US markets. Sales in Europe are minuscule.

May as well just use GRP then

From a practical point of view, yes. From a marketing and snobbery point of view, less so.

It will still weigh around 1600kgs I expect.

The M4 CSL will have the juiciest bits (like the M3 CSL) to reduce weight below 1500kgs,

BMW will be using carbon more widely in their main stream cars to save weight. They have invested a sh!t load of money in their carbon production facility in the US. It's not just for the iSeries cars.
They have said the M4 will have more carbon to reduce weight and get it nearer the E46 as stated by others here.

I never said otherwise. I said they wont be using heinously expensive CFRP in order to save every last gram or to provide structural rigidity. Unless you're saying they're going to be making M4 chassis components out of CFRP?

CFRP body panels do save weight compared to metal but they are still largely a gimmick because other plastics give 90% of the weight reduction for 50% of the price.

There carbon facility...
