The mags are printing more news about BMW making the next M3 and M5 turbo charged cars and presumably these are well-connected individuals printing the stories to gauge public opinion. Are BMW insane? I understand that they need to reduce emissions across their range and that they need to make their cars more efficient but surely they can do that to a normally aspirated engine with their efficient dynamics technology? Why force turbos down our throats? (pardon the pun)

Surely a new naturally aspirated V8 M3 and a new V10 M5 with improved efficiency, even better engine noises and 8,500rpm engine cutouts are just what the doctor ordered and precisely what M customers want.

I know that BMW make fantastic turbo engines but if I wanted one I'd just buy a 335i! If BMW decides that all new M cars will be twin turbos, I'm voting with my feet - the new RS5 will have a V8, as do the Merc equivalents - that'll be where my money's going!

Is the RS5 having a V8?? I thought it was having a pumped up version of the Supercharged 6 as in the newest S4??

Bigger heavier subsequent models + tighter emission requirements = technology not yet available to fulfill current requirements via NA motor; what is the easiest and most cost effective way to satisfy the remit? Turbo chargers. They are not all bad and have come along way over the last 10 years, should BMW choose to go this route it could be the best thing to happen to turbo charger technology for a while but will it spoil what we currently know as M powered cars?

For me turbocharging goes completely against the idea of the M cars always being NA, high revving machines, however, I do see the possible need for it in when fuel consumption and emissions are also key factors (cue: the fuel consumption of the E60 M5 and a pathetic 70 litre fuel tank) but what horrifies me more is the idea of an M version of the X5 and X6! Big, heavy, automatic only, 4 WD SUV do not sit very well with the M ethos, IMHO... Guess "M" will be more like A "M" G then!

it's depressing, but it's the future, I'm afraid. The V10 and V8 are magnificent engines, but they use extraordinary quantities of fuel. Keeping the performance or increasing it while reducing the fuel consumption by a significant margin would be a tall order. I've managed with difficulty to reconcile myself to turbo M engines (after all, one of the first M cars, although without the designation, was the 2002 turbo, and BMW's 1980s turbo F1 engines were peerless. What I cannot reconcile is the X5M and X6M abominations. By all means make powerful 4wd monsters, but do not call them M cars. They are not what M GmbH is about.

According to Autocar this week it will be a V8 with 450 bhp Hmmmm....cloud9

I just think it's a shame - I'm sure most "M" owners want the high revving NA engine - in fact in the last 3 iterations of M3, I'd say that the engine is what has made the car. It's certainly the centrepiece of my car and is what makes it special! Surely, inthe overall scheme of things the number of M3 and M5 sales is relatively small, so why can't BMW cater for the customer's requirements outside of the mainstream models. I don't drive that much anyway, so the fuel cost doesn't bother me and although I care about the planet and recycle etc, I'm a car nut and it's pretty much my only vice and I want my next car to be a NA V8 or V10!

Pour moi, the best trajectory for ultimate höonschleppen would involve the existing V10, extrapolated, like some ruddy great variant on the former Caterham technique of stroking the venerable K series to the point of detonation as per Superlight applications...

Except here, it would be bored out to maybe 5.7 litres, the n/a power would crescendo at the high fives whilst a true CSL style regime would batter the blubber.

A 1450 kilo //M6 with say, 580 bhp, bigger brakes and some scaffolding?

Where, the f@ck, do I sign??? spermdrivingevil

That would be the 5.7 litre V10 stroker engine offered by Dinan (of the US of A)

I'll buy that for a dollar (or rather more actually).
