Hopefully its like the S54 just rawness which was lost throughout the years. Amazing 333 HP and 262 lb-ft of torque out of 3.2L with a 7900 redline. That was engineering at its best

Fuel consumption is totally irrelevant, and to a certain extent I'm not even worried about power output. The only things I really care about in my motors is the way they deliver power (I like a relatively flat torque band with peak power at or near redline, but I don't like engines that are overly peaky. I loved the powerband of the E9x M3 but would have liked it even better if it had 25 more lb/ft of torque from like 5-7k) and the way the engine sounds, not just at wide open throttle but at all times. For these reasons, I would prefer a new version of the V8 or even an updated straight six over any turbo alternatives but I'm not entirely against turbos, I definitely have no problem with the motor in my car.

No it's not. Maybe it is to you and the rest of the U$A, but elsewhere in the world people pay double or triple the price of your gas, and depending on the country also yearly taxes based on the fuel economy [or polution] of the car.
Less fuel economy [more polution] = more expensive at the pump + (a lot) more expensive on your tax bill. |

Interesting poll but I did not vote. Redlines are a key ingredient. I like that you mention consumption as well. It may not be folks deciding factor but it is still important.

I would love to see an "S65B44Tu", aka a revised version of the GTS/CRT engine with stronger internals for an even higher redline and power output, or an "S65B48", aka a stroked version of the S65B44 at the current redline but higher power output. Bonus points if either of those get a flatplane crankshaft.
None of that is going to happen, unfortunately.

If there ever again an revised (Tü) of the S65 could be, then it would remain with the capacity to 100% for 4.0ltr, if only to reduce the consumption. About the by swamp2 quoted Redline issue ... I'm also 100% believe, that if any one of both turbos could spin up to 7500rpm, it would then be the V6, because in the case of the I6 even the technical preconditions of the long crankshaft speaks against an higher redline.

Odd, two of the least important things for an M engine. From my perspective:
Power Shape of power and torque curves Redline All come well above torque and fuel efficiency. Are we interested in the same car?

You missed an important one:
S63B33 TT V8 with an 8000 RPM redline. The shorter stroke vs. the existing S63B44 allows for the higher peak RPM. Though higher RPM may also preclude the use of Valvetronic. Either way, this engine would, in my opinion, be a better fit within BMW's current product strategies than either an S65Tu or any V6. Of course, this also does nothing to address engine weight - something BMW will no doubt manage carefully with the new I6. |

I don´t think that an I6 based on the N55, re-inforced, with an bigger turbosystem/more turbo and the needed pipes could be lighter then an N54 ever a little bit heavier ... I think it would would weight somewhat between 195 and 200kg |

So as far as weights go: S54 > S65 > "S55" IMHO. Last edited by mkoesel; 07-09-2012 at 03:04 PM.. Reason: Duh, S54, not S52. |

I recall some great ambiguity in the numbers on this point. Are there official numbers that show this consistently in an apples to apples comparison? Thanks!

Well I used the rumored numbers. Mine are the M3 E90 is 100 kg lighter than the M3 F80, 50 kg lighter than 335i F30.
