Bi-turbo confirmed instead of triple-turbo?
In the Car Magazine article that was published last month, they've stated that the new powertrain would include a bi-turbo instead of a triple-turbo (point #4):
http://www.carmagazine.co.uk/Secret-...t-you-to-know/ Does this mean all bets for a triple turbo are off? I was seriously hoping for a triple turbo engine (two tiny turbos, combined with a large turbo just like the M diesel offerings in Europe). How amazing would it be having near maximum torque just off idle with a set up like this? Could we get scott26 to confirm this? Also, since this is a next generation motor, and unrelated to the M5/M6 v8, is it possible for the redline to be substantially higher than 7200RPM as found in those? |

Car Magazine has also tried to pass renders of the M3 and M5 off as real images so they have little credibility IMO.
They may end up being right in the end either from luck or actual knowledge since anyone has a 50% chance when guessing either 2 or 3 turbos. But I'd take their info with a huge block of salt anyway. |

Yea, so automobile mag is betting on the triple turbo. I think I am too, I find the term "multi" turbo was thrown around by decent sources on bimmerpost on a couple occasions. I feel there would be no reason to use the word "multi" if it was a twin turbo.

This engine, an 3.2ltr.V6 BiTurbo has run into an endurance test on the engine test bench with this 8.000rpm ... which has probably led to the rumors of a redline of 8.000rpm for the new M3/M4 engine But the probably next M3/M4 engine, an 3.0ltr.I6 TriTurbo will almost certainly have a redline of ~ 7.000rpm.

Isn't the 991 GT3 a naturally aspirated engine? Not turbo

How come were assuming that more than just the engine block from the S55 will be used and bored out? the 991 GT3 engine is extremely different than that of the Carrera S even though the same block is used initially. Is there a source that indicated they would be very similar? Assuming the M5 revs to 7200rpm, I think it would be impossible for the M3 to rev lower than that. I think realistically we should expect 7200 or 7300 as the minimum. 7200-7600 would be expected, 7600-8000 would be a nice surprise. |

If the gen to come is to utilize bigger turbos pursuing high end at cost of low end reponsiveness that N54/55 is good at, which is most likely the case, it's not worth the wait at all. Nobody is going to be fine with a lighter and less powerful M5. |

Take N55 updates and apply it to the N54 setup... Call it the S55 and have three sources of intake charge air
1. Scooped from kidneys (air cooled ic) 2. Driver lower louvre intake (water cooled) 3. Either passenger lower louvre or from hood The current M3 provides 3 sources of intake air and so will the new one It may have a third electric turbo but I'm thinking either N54 set up or dual twin scrolls |

Probably not. We aren't likely to get such engine details until BMW is ready to release them, which will probably happen sometime later this year.

That would mean a brand new engine architecture with high costs. The whole point of working with an existing engine as a basis is to use existing tooling and maintain compatibility with some existing parts such as timing assembly, accessories, mounts, etc. |
