i love how the M3 builds the power up high. not to mention revs well past 8k RPM. Most cars today have the flat power. the M3 S65 is just different which some people like. i do see how some people would want more power down low and would make the statement of the S65 not being well suited for the M3. but for people like me, who wants a engine that is not practical and needs to a mad man behind the wheel to have fun with it on the streets. the the S65 is great to be honest my M3 sees 8300RPM on a daily basis. |

To the OP and everyone else:
There are numerous German tuners that do engine swaps "on a daily basis" Manhart and others have done 1 and 3-series with the S85, S65 and S63 (twin turbo)engine. Manhart even did, on customers request, an E92 M3 with a tuned N54 and X-drive So, all of your wishes can come true via aftermarket tuning companies (at least in Germany) |

Not saying the S55 is no good. It is lighter (heck, two less cylinders) and more hp. But it will feel different. It may be faster but it will lose the magic of the S65. Now, how much magic of its own will it make? I can't wait to see. Cheers.

I sincerely feel that the response in my f30 335 (sport mode) was a lot better than my current s65 (power activated). I personally predict the s55 to be much better than the s65 in absolute terms (not just good "for a turbo engine"). |

even guys over on the Audi forum are upset about Audi dropping there RS5 high revving n/a V8, and going with a TT V6. though AMG is probably keeping a V8 for next C63. people will miss the big 6.3L n/a V8. the power and sound of that engine is unreal. while sure many do welcome the new turbo era. |

It sounds like some teams might be experimenting with electrically spooling the turbos and also using the turbos to generate electricity. It's not crazy to imagine a power control algorithm which uses harvested energy to spool the turbos whenever the driver is not on the throttle and when on the throttle, uses energy to recharge the energy store and also to supply power to the rear wheels.

It can be a bit tricky to discriminate throttle response and lag when widely varying throttle maps are used. For instance using the aggressive throttle mapping in the S65 M3, I would say the throttle is too sensitive at low throttle openings. This can give an illusion of a "faster" car or better throttle response or it can just make the car downright jumpy and too sensitive (which is my evaluation). However, I find it next to impossible to believe that you find a turbo charged N55 to have a better throttle response than the S65. You really must be confused.

and you even went as far to say "a lot better" the S65 is known for throttle response. |

Lighter - that's good, not by much. Fuel efficient, that's great, but surely it is a relatively low priority for a sports car? Perhaps engine character might come above carbon footprint for such a car? Torque curves are almost if not entirely meaningless for the performance of a sports car. Wheel torque is slightly more meaningful but peak power tells us almost everything. The power of science, engineering and experience allows one to form very resonable conclusions without direct experiential knowledge. Exactly my point is how the S55 will and does run out of steam at high rpm and will almost for sure need to be short shifted to achieve maximum performance (at least in the latter gears). How sporty is that...

I've also heard people talk about the poor throttle response of the S65 at low rpm in higher gears. Personally I prefer the term throttle modulation because it seems more precise. And to be pedantic, the response to the throttle at low rpm in higher gears is poor when compared to a turbo motor Pat |

But lighter ... I don´t beleave that the gross weight of the S55 is lower than the gross weight of the S65 -> I heard numbers of 205kg (S55) vs. 202kg (S65), that is pretty much the same weight class. |

Sorry to nitpick but the M156 was a 6.2L as I'm sure you are well aware. Stupid Mercs and their 6.3 badges. And you are right - that engine will be dearly missed, but I'm sure the M177 will be freaking awesome as well. |

My S65 has such quick throttle response that if I'm at a low speed and low gear (moderate rpm level) and have the power button on, If I hit the throttle sometimes the car 'bucks' as it jumps ahead, pushes my foot off the throttle, slows, and my light pressure on the throttle is enough to push it down again -- repeat a few times for a weird 'jerking'.
Doesn't happen very often, and it has to be the weird specific set of above circumstances, but in that case (and that case only ) maybe a decreased throttle response wouldn't be a bad thing, lol. |

You also have to consider/include the extra cooling in the S55 that the S65 does not have.

I'm going to laugh my ass off if this S55 engine becomes adored. People were fairly resistant to BMW going to the V8 too, and people were writing it off long before they were able to drive it because it wasn't an I6.

There is also NO WAY an I6 will sound as good as a V8, no matter what exhaust you put on it. As for efficiency, the new Porsches get excellent mileage, make great power and don't have a blower. The S55 is all abou saving money. If you don't track the car, you'll never really appreciate what it's like to rev out a high rev motor that lets you reach the next turn without needing to shift.

Agree completely.

Let me get this straight... You are swapping out parts designed by some of the top engineers in the world because some guys sponsored by a company told you it's "better??" But when you ask the same guy about tracking, "oh no, I have a kid now" or "I just detailed my car." or "i just got new tires."
