Where did you hear this? I'd venture that your "info" is wrong. GJM already said he made a typo and meant to type "vent" not hood. Clearly there is a hood bulge in these pics and the latest test cars have it too.
As re the article, the written portion is pretty worthless but thanks hugely for posting the pics. Looks good, I'll be getting one. Scott- can you confirm a CFRP roof for the sedan? |

You mean horizontal line near the roundel? Doesn't bother me in the least. It's a more-than-acceptable trade to get the sharper lines and move past the sickly yellow angel eyes on the E90s.

Well that would make even less sense since the B38 is the three cylinder. the B68 (I accidentally typed B58 in my previous post) is the next I6 with which the B38 and B48 I4 will share 60% or more of its parts.
It is possible the new M engine will be a member of this family too but as I say, I am a bit skeptical. |

I see no chance that BMW/M-GmbH develops two different I6 engines ... and an "S68" based on the B68 would never reach 8.000rpm redline ... but there is an small possibility that two B38 blocks could also put together in V-form to use an S63Tü style turbo-system. |

I disagree. In the past there have been a number of M engines that were not based upon a current generation series engine. In fact, if the M I6 is indeed based upon the the B68, it will be the first ever M engine to my knowledge that debuts essentially right along side of a brand new series engine on which it is based. And actually, we don't even know if the B68 will debut this year with the F32 or not - this is still only speculation. If that does not happen then there is almost zero chance in my opinion that the new family will be introduced with the M3.

But what you say about two 3-cylinder put in V is quite possible. There were those engine specs of 3.2l I6 and 3.0l V6. We thought the V6 displacement was wrong because it would rather have been 3.3l, then we came to the conclussion that it could be based off the S65, the as you say, 1.5l I3 226 PS(B38) + 1.5l I3 226 PS (B38) = 3.0l V6 452 PS (B68) sounds just like it. Having seen the acceleration and sound vid of the 3 cylinder 1 series, it was amazingly fast. This could really be the engine. It means it would be lighter than a 3.3l V6 based on the S63. The M3/M4 is the greatest engine enigma in car history. |

SO ... if the M3/M4 gets an I6 the only logical conclusion is that it was based on the B38/48/68 engine platform ... and its also possible that an new engine debuts in m form ... look at the N63Tü which debuts in the M5 as S63Tü ... and also the other infos made sence ... that they would use the latest valvetronic system (like in the B38?). FOR me there is only one reason for two totally different 6-cylinder-engines, build side by side and with the same displacement, ... an 3.0ltr.R6 BiTurbo for all .35i/.40i and M.35i/M.40i and an unique and stand alone 3.0ltr.V6 BiTurbo for the M3/M4 ... both based on the B38 platform with many common or common produced parts. BUT we are already sure, that the new M3/M4 engine could only be an I6 !!! |

So, yes, I think a similar scenario is very possible today. All we know for sure is that the M engine will be based (however loosely) on an existing series engine. In theory, it could be the N54, N55 or B68. You are putting all of you eggs in one basket and committing yourself to latter as the only possibility. I am allowing for any of them, while suggesting the the N55 seems the most probable to me at this point. Clearly the M engine could not have be based upon the new engine family if its development was not progressed far enough along yet when M started their work. The N54 and N55 on the other hand we know for certain are available and have been for years. We don't know exact development timelines for the newer engines (at least I don't, and I doubt you do either), so for now we cannot (at least I can't) make a conclusion yet. Quote:

But still, it is quite tempting to think about a mid-front mounted V6 in the M4.
It is also hard to understand how Mercedes AMG can build specific engines for different models; TC 2.0l I4 for the A AMG, TC 4.0l V8 for the C AMG, TC 6.0l V12 for S AMG, TC 5.5l V8 for E AMG, NA 5.5l V8 for SLK AMG. M5/M6 engine is "ok". M3/M4 engine might be ok. But if M2 engine will be a tuned N55, that will be an EPIC fail for the second time (1M first EPIC fail). The M2 better get a special I4 or a detuned M3/M4 engine. |

Infact S5X series engines are totally different, block are bored and longer than std. M5X series and its made on castiron, Crank got bigger main bearings, rods are totally differend, all engine parts are forged and cylinder head is special too, you can´t bolt S5X cylinder head on M5X engine etc... Everything in engine is totally differend than standart M5x engine, so how can you say that they are only little modifed?
