From M3Post forum

Following this thread, I came across some more speculation on the engine powering the next generation M3, called the F3x M3. In the past, SCOTT has mentioned that the N55 TwinPower inline 6 would be used as the base engine. No firm news yet, but here's some information on what BMW M is working on to turn the N55 into a real M engine.

First of all, it's my understanding that BMW M is still considering several engines or rather engine layouts for the next M3, so I can't tell whether this particular engine will actually make it into production, only that this is one possible layout they're looking into:


ENGINE / TRANSMISSION:

This engine -- let's call it S55 -- underwent heavy modifications to meet the prospective output of 450 HP:

- The displacement will be increased from 3.0l to 3.5l. We've had a discussion on this possibility earlier here, and came to the conclusion it wasn't possible based on the N55's cylinder spacing. What we didn't know back then is that BMW wouldn't touch the N55's bore, but implement this increase solely by adding stroke. In other words, crank and heads will be different from the N55.

- Furthermore, the S55 will have a new turbo layout. There's no word yet on the exact layout other than it will be aspirated by the help of three turbos. BMW followed a similar approach with the N63 V8 engine on its way to become the S63 engine powering the X5/6 M and soon the M5/6 models. The N63's two individual turbo chargers (each taking care of one bank of the V) were replaced with two twinscroll turbo chargers, and thus the amount of individual scrolls has been doubled. As some have suggested already, this approach can't feasibly be replicated on an inline 6 engine (or any 6 cylinder). There is no easy way to split the exhaust pulses of 6 cylinders into 4 turbo scrolls. Instead, three turbo scrolls were found to be the right solution. Whether that means one additional turbo to the existing twinscroll turbo of the N55 or three individual (single scroll) turbos, or even one tri-scroll turbo remains to be seen. Personally, I'd expect three individual turbos because that would allow for rather small chargers with a low inertia.

As of now, it sounds like the next M3 will only be available with a seven speed DCT transmission. No 6MT! Also, as things look now, there will be an F30 M3 sedan complementing the F32 M3 coupe and the F33 M3 convertible again.

We brought you the news of the X3 M reaching its mature phase of development last week. Now we can add the first, yet most important, fact about this car: It will basically share the engine with the F3x M3. In other words, BMW would choose the same route as with the X5/6M and let an early version of the S55 engine debut in the X3 M.


E90/E92 M3:

Finally, here's a heads-up for everybody disdaining BMW M's decision to turn away from high-revving, naturally aspirated, engines: You better be quick to put in your order for an E9x M3. The rumor has it that the E9x M3 ends production in 2011, including the E92 and E93 M3.

digi gor you really done a good research on the next new M3!! It would be nice if the next generation M3 still come with a N/A engine with the ITB, maybe like a V10 NA engine with about 500hp+? i think the M division should give the new cars with turbo-ed S engines a new name, for instance, Motorsport Turbo-ed Racer("MTR" :mrgreen: ), instead of still calling them "M3" ... :lol:

M1 will be a real benchmark. It should set the base for what to expect for this new M3.

Hi jj,

think the info above is more speculation than any actual deliverable by BMW but its an interesting discussion. X:P

yeah, very interesting ... if the next generation AMG C63 coupe coming with a new 5.5-liter V8 biturbo engine, BMW may have to consider to turbocharge the V8 engine with 2 x twin-scroll turbocharger for the new "M3" as well...

More insanity from AMG as always. If oil prices keep moving up and closing in on the 3 digit figure, AMG may just need to re-consider smaller engines. :lol:

400 - 500 horses of insanity is probably more than enough for us on the road, but then again we have some members here that can take/handle more. :lol:

I believe moving forward (2011 and beyond) the keyword will probably be "POWER TO WEIGHT". The hay days of cheap oil are running out, and with oil companies now starting up their oil sands operations (remember for oil sands to be viable business, oil needs to sit $100 or greater), they obviously feel oil prices are going to hit the magic $100+ pretty soon.

It will be very interesting to see how Lotus performs with its new lineup of super-duper sport cars.

I concur entirely!!

Cars are so damn heavy these days notably from a number of manufacturers including BMW.

'Efficient' dynamics my ass.

Agreed!! And I think that is why BMW introducing these Forced Induction models. I think they are really great cars, but it is just that BMW shouldn’t mix up these FI models with the ///M. And sad to see BMW following the rivals’ performance competition making the M3 like an elephant…

M3, such a legendary car, shouldn’t the manufacturer always putting the nice little L4/L6 N/A S engines for it and keeping it the most fun and balanced car to drive on the road and track? Simply just like the way the VW keeping their GTI… Sight! (I guess the new management team is very sales driven and very forward thinking, and also very creative, you never know we might see a special ///McDonalds version one day… hahahahaaaaa)
