Actually, almost all the M engines have been based on series production motors. The E46 M3's S54 was derived from the M54, E36 M3's S50 from M50, and the E30 S14 from the M10 block. Even the Mclaren F1's S70 was developed from the M70 block. The S85/S65 are the first to be truly bespoke and with BMW's desire to save costs, I believe they would like to return to that traditional formula as they have done with the S63/tu. With all the rumors flying about the V6, I have faith that BMW will stick to the glorious I6 for the E8X generation. It is just not financially prudent to allocate the resources to make a great V6 (not to mention the backlash from the BMW enthusiast community).

1. Yes sound is REALLY important to a lot of folks. An aftermarket exhaust set up can help but it can't turn a FI sounding car into a NA high revving sound.
2. This car does not sound very good to me. 3. Yes the production car will sound different than this one, for sure. 4. I'd be willing to bet all of you posting that you can tell what the engine configuration (I vs. V) is by the sound could not actually do that in a blind aural test among Is and Vs.

I think we've already seen the tri-turbo experiment or derivation from a previous m-engine - the tri-turbo diesel engines in the X550d and X5d. Also
the development of the 1M helped BMW stress the efficiency and resilience of a FI engine on a track. The sound of the F80 M3 in that video is definitely I6. The engine will combine direct injection, valvetronic and three turbos (small, medium and large) to simulate the linear power curve of an NA motor (similar to what we have seen with the tri-turbo diesel). V6 would be an interesting move, but I don't think it's as easy as chopping two cylinders off. Plus they sound like crap (go listen to a Nissan or Infinity V6 accelerate) |

It's going to be a V6 bi/tri turbo, sucks but true and needed to make bigger power and efficiency. An I-6 would require a big turbo/s and much bigger displacement to make reliable ~450 HP. 3.5 liter V6 twin turbo is my bet. Tuners are going to love and no more stupidly overpriced superchargers

I would put a cent at present to some concept.
Even employees of the M-GmbH tell everything-except the truth! Thus speaks one half of the V6, the other half of the R6 ... It is interesting but just a rumor that has surfaced: Latest BMW insider info, 3 sources. Here we go: Dubbed "S54b42 '(e46 m3 had notice S54b32) N / A 3.6l inline 6 ~ 466hp @ 6700rpm-7700rpm ~ 434hp @ 8300rpm redline ~ 390tq from 4300rpm all the way up to 7500rpm ~ 350tq @ 8300rpm redline performance exhaust Fuel Economy 27mpg highway 20mpg city M3 F80 3180lb dry Carbon roof Carbon hood and trunk 6 piston front 4 piston rear, drilled or slotted rotors 14:5:1 steering (same as e46 m3 csl and comp. Package) Race tuned, adjustable suspension 19 inch BBS wheels, e46 csl wheels by inspried but "new / updated" look Michelin PSS optional Pilot Cup tires Sprot Whether it really is true, I can not say .... ...but as of the release-date I can tell you something: It will not take more like 12 months! |

I recommend you once read in various forums ...
Of particular interest is always the fact that knowledge with each new video, the self-proclaimed experts no matter what the bears under the hood ... and the only sound in a video! For example, a 100% sure that this can only act in a I6 .... and the others are sure 100% that the sound was definitely not a I6 can be ... And at the end are all as smart as previously... |

you know I've been following this new M3 release for a while and while what a lot of what kueks29 says seems far fetched, i.e 3180 dry weight-- one thing does seem interesting, do we know for sure it will be turbo charged?
What if what really comes out is a NA inline 6 or V6 for that matter making 430 -450 hp and close to 400 ft lbs of torque. That would be very inspiring to say the least and would be a game changer. Sadly nothing points to this direction except misinformation perhaps. Reading into BMW is like trying to read our own federal government it takes a lot of deciphering through rumors, theories and hearsay to get to the truth. |

lol you are funny, I like that.
Unladen weight then would be 3500 lbs? Around 200lbs less than e90 m3, Perhaps this is attainable but you missed the major point of my post, which was to give some thought to what you claimed as being the new motor s54b42 <<why would this not be s54b36 if 3.6 liter? Glad to have such a welcome though, thanks |

I agree with the sound not being up to par with the S65 V8. Everyday the weather is nice, I put the top down or the windows down, turn down the radio, and listen to the engine. It is one of the reasons I love the car so much.
Having said that, I would think the exhaust on this car is not likely the finished product and still has a year before release for fine tuning. Also, it seems to me that this driver was not pushing the engine as much as handling. At a few points, the wheels were squealing from what seemed more like aggressive turns, without necessarily pushing things. I'm not a racer, just offering a thought. You all can tell me if I'm crazy. Just didn't seem like this car was really being DRIVEN. |

I said clearly that this rumor was posted in another forum! Click here, because you can find the original post. Moreover, it seems more of a late April Fool's joke act |

that's A LOT of stress for a turbo motor at that rpm, esp for an inline 6?

Normally the numbers after the "b" in the engine designation signify the displacement... 3.6L would be S54b36 not S54b42... IDK MAN |

Most are forgetting something. All V6 engines on the market now (Nissan GT-R, Nissan 370 Z, Mercedes C350, Mustang V6) are at 60°. The M3 F80 engine, if it is a V6, it is at 90°. You think BMW will make it like the old GMs? No, they will surely install a counter-rotating balacing shaft, that will makethis V6 almost as smooth as an I6. That is why the sound is not that different between such a V6 @ 90° and an I6, so we can't tell it from the vid.

I think that they would use an special firing order for the cylinders like they had done it with the S85 V10 ... same result like an counter-rotating balancing shaft, but no weight increase and the reason for the different sound ! Last edited by Uli_HH; 04-03-2012 at 05:55 AM.. |
