E90 M3 vs. E92M3
Can't wait till the mags start comparing the two so we can see the differences, beyond the obvious ones of one has more doors

didnt they claim also that the sedan is slower...
and now that we have a CF roof on the coupe, the handling of the Coupe is a little better? (don't flame me if im wrong just what I heard) but im excited for some reviews lol

We'll see about the handling. If we go back to the e46, the sedan without folding rear seats (like mine) was much more rigid than the coupe. After driving a coupe, the difference was quite evident. I'm not sure if their is a tangible difference in the e90 / e92 or not.....

But they did say that the coupe E92 M3 is stiffer than the E90 sedan, but I'll wait and see how they both drive. I'm leaning towards the sedan myself. It comes down to cost for me. If the E92 is priced higher than what I'm willing to pay (..with the options that I'm interested in), then I will save a few grand and opt for the sedan. I have gotten used to the utility of my 4-door E90 330i. |

I would assume, due to wieghing less, having smaller coefficient of drag, and being stiffer, that its a safe bet that the coupe will be a better performer than the sedan.
Though, im still going for the sedan .

The coupe weighs about 25 lbs. less. Not much difference at all. Also, coefficient numbers are relatively equal for the sedan/coupe. We'll have to just wait and see how everything truly pans out once both vehicles are on the streets. |

E90 vs. E92
Autoweek did in the last issue, "...with the M3 sedan offering a slightly more compliant ride than the coupe due to the slightly inferior ridgidity of its four-door body." Keep up here, wouldya?

I can count on two hands the times I've used my rear seat for anything other than carrying drycleaning, but if you have a family, that changes everything. I do like the folding seatbacks, though, so I can stick my bike in.

Are you saying the folding back seats decrease chassis stiffness here? For that to happen, there must be cross braces or other structural members behind the non-folding seats in the sedan. I seriously doubt that. Any evidence to back that up?

Im sure there is at least a metal pannel behind the seats if no fold-down option were there. If thats the case, then twisting forces will be reduced. It doesent necessarily need heavy duty cross-bracing for it to work.

According to BMW info the E92 chassis is quite a bit stiffer than the E90 chassis (sorry I don't have a reference but a search on E90post should turn it up). I am not sure how the fold down seats figure in here, but I do know you cannot get an E92 without fold-down seats in the US (M3 included), so I assume the above fact takes that into account (if indeed the folding seat option even has an effect on the chassis stiffness this generation).

The opening behind the fold down seats in my E46 is not that large actually. Which means that whatever is running across the car on the perimeter (above and below) of the opening probably adds to the stiffness just as much as a cross brace would. A cross brace would be more effective since it could be running across and up/down at the same time. |

Per BMW, and tuner info. I know it's posted on E46Fanatics. I can find the info if you'd like. Whether it will hold true on the new ///M sedan vs coupe is another story.

Here is the info....
and...
As you can see, the sedan w/o folding seats is the stiffest of the bunch. |

Well, looking at my E90 sedan, the back of the seat is covered in the same carpeted material as the trunk (..so you can't see any of the bracing). There was a picture posted on E46Fanatics. Let me see if I can find it.

If they have a couple of cross braces running an X pattern, that would explain this.

Excellent post...thanks Greg. I'm new to the e90 scene and have spent my first 6 years of bimmer lust over @ www.bimmerfest.com. Unfortunately, there isn't much e90 M3 talk going on over there. So, I do plan on keepin' up and spending more time over here. BTW, not only do I prefer the sedan styling, I need it as I have 2 boys! |
