Its not hard gents. The e92 motor was basically 2 off the v10 of the e60. Same for text time. Just take two off. So it will be a v6 TT off the same architecture of the v8 TT of the upcoming m5.
just my dumb assed speculation. wait and see. But to me I think the e92 with the 8400 rev limit... you just cant replace that. It is 1000% wait and see with what the next m5 will look like IMHO. 7000 rpm limit or below = fail.

I think my post is slightly better than "speculation" isn't it. I'd give it educated guess or hypothesis at least. Quote:
You totally made that word up. It's pretty cool though. A major consideration of engine configuration is the engines balance and efficiency. Cross plane V8s like the M3 are naturally quite balanced. V6s are both poorly balanced thus require extra gear driven balancing and are less efficient than I6 because of that and the entire extra head and valve system. Since BMW has had no production engines ever in this configuration it is extremely unlikely. I6 is the most efficient and balanced engine configuration around. The only real drawback is its long length, making it typically unsuited to a FWD application.

F32 M3
So, from these guestimations, the F32 M3 would spanked by the current R35 GTR, not to mention the 2011 C63 AMG.
That's depressing.

(Apology in advance if it was already answered in the thread. It's a long thread & I only glanced thru it.)
At this point, do we know w/ certainty if it's I6TT or V6TT ?

Sorry, but I cannot take credit for the word creation. We tend to use "automotive" in English when automobilistic could be used as well. We do ride in automobiles afterall.

Also, note that it is not guaranteed to be a twin turbo either. |

Regarding the growth point, that's not particularly important since they don't typically bump the power of the car over its lifetime. If they need more power for a future generation, they can just switch to the V8 at that time.
As far as reliability, that might be a stronger point, especially given the troubles BMW has had with its modern turbocharged I6 efforts. However, the problems don't appear to be due to squeezing large amounts of power from a small displacement motor. Though, some may be quick to point out that the N63 and S63 are not suffering from the high failure rate of the N54/N55 (but as I understand it there have still been some issues with the V8s, or at least the N63).

From everything we know today, the next M3 will be a twin-turbo inline 6, and as many already stated probably a variant of the N55 with two turbos instead of just one and a larger displacement. A twin turbo 8cyl engine is irrealistic, already from a fuel consumption standpoint (and yes, that has also become relevant for the M cars nowadays), but also because power-wise it is not a necessity as an inline 6 is largely sufficient for the roughly 450hp that are targeted. Time will tell, of course. Alpina_B3_Lux

High rev turbos
The new Mclaren MP4-12C has a twin turbo 3.8L V8 with an 8,500 rpm limit (600 hp). Obviously this is a supercar that is not in the same league as the M3, but it can be done on road cars.

Fair enough. For what it is worth Autoblog had quoted the 8500 RPM figure as well until the official reveal. I am sure they had a good reason to change their info, although perhaps it is as simple as the red region on the tach starting at 8000 RPM or something of that nature. Like I said above, fuel shut off could very well remain at 8500 RPM

The thing is, no other car in the class will have a high revving motor either. The upcoming (current in ROW) RS5 will, but that will probably be gone just about the time the the F32 M3 arrives on the scene. Doesn't make it non-viable as an alternative, however, the current M3 is besting it in just about every comparison test. The new one will likely decimate it performance wise. That said, at least some other cars in the class will have V8 power. Even when the high revvers are all gone, I am still inclined to choose a V8 over an I6, assuming closely competitive performance in other areas of course. |

There are two things that need to happen for me to buy the next gen M3
1. HPFP issues have to be resolved. Completely. 2. 4 door version that isn't a bastardized GT. I'm sorry but the 5GT is ugly and the M3 GT can only get a little less uglier. You'd do well bringing a M3 wagon to the states. |

M-W is slacking, but will catch up eventually. I suspect that you along with all speakers of one or more of the Romance languages (a.k.a. Romanic languages) understood its meaning in context. Moving along... Isn't it time for a turbo poll; Dealbreaker or not for the next M3?

The current M3 with competition package has gone up against the C63 AMG (with "competition" package or whatever they call it) and has matched it in the straights and bested it on the track. A close battle but also all subjective evaluations also favor the M3. The GT-R is a bit on an anomaly. The F32 M3 certainly be tunable to match the R35 GT-R but that will be a fairly aggressive tune (perhaps software+hardware). Keep in mind the GT-R is, by most reasonable accounts, putting out about 530 hp. It is also a clear anomaly in term of performance to price ratio. I suppose last but not least because the GT-R is for all practical purposes a 2 seater, many don't consider it a direct competitor to the M3. If you want GT-R performance with a GT-R price, buy a GT-R. Although I haven't driven one, be prepared for what most describe as a soulless car... The flip side of that is one also quite easy to drive very hard.
