I somehow massively doubt that it'll be THAT light. But we can always hope.

One can only hope.
But for the first time there will be a different internal code between the M and the standard 3-series platform, (f80 vs f30). Lets hope this means that the structures are so different from each other that there will be room for massive weight savings. Why would they else use different codes?? Once again, one can only hope... |

I don't see why not since the current e9x is actually 3550 as weighed by many owners indepedantly through the years. The e46 was 3450 which is much higher than most actually know. So to shave 200 pounds is not super easy, its also not really that difficult for a manufacterer with access to change the sound material, body panels, suspension component materials/subframe material etc
I expect it to weigh 3400 to be honest which with 420 "rated" and more likely 450 true hp as they always underrate engines |

Lets stop spreading bad data
If it achieves 3300 lb curb weight, this car will break some hearts and egos with that powerband.
OT and a but needs to be said. Quote:
Here is real data: My car came off the factory floor one of the fattest M3 coupes (I called her Miss Piggy back then) you can order and even with additional stereo components STILL did not achieve the weight you claim. With almost a full tank of gas, sunroof, SMG, PDC, OEM 19" boat anchors, nav and a 12" speaker box + 5 channel amp (+65 lbs) topped out at 3410. ZERO weight reduction - tool box and M mobility kit still in the trunk. I was trying to get it as FAT as possible for my initial weigh in before I put her on a diet. This weight from the Long-Acre scales (http://www.longacreracing.com/catalo...p?id=1&catid=1 ) was verified by the CCA at several Auto-X events that first year on their scales as well. Just for reference, non-sunroof 6MT car is right at or below 3300 stock on the same scales. Sunroof (+45), SMG (+15) and NAV (+10) do not add 150 pounds to the 46M's weight. I have removed those components from my car and weighed them and the car afterwards. Miss piggy today sits at 3290 lbs with the full interior, the same stereo and 1/2 tank of gas.

I see in the attached article, they mention CCB in the mix to get to this weight. No doubt CCB will be an expensive option to save the weight. Standard steel braked cars will weigh +30-40lbs

On a M5 it saves 42,8lb, probably a little less on a M3, since the rotors and calipers will be smaller in the first place, (6 piston front cal. on M5, probably 4piston on m3)

Interesting. What does the CCB option cost on the M5? Is that the $6500 "performance upgrade" listed on the build site?

http://www.f30post.com/goodiesforyou...3/BMW-M4-j.jpg http://www.f30post.com/goodiesforyou...3/BMW-M4-g.jpg They are definitely 6 piston front calipers on the front and the rears look to be 4 piston, not those single piston sliders like on the M5/M6 CCB option...

But I was talking about the standard steel brakes, those will probably be 4 piston fixed alu cal. at the front and 2 piston fixed at the rear on the new m3/4. In other words, smaller and lighter then the standars on m5. Point is that the difference between CCB and steel will be slightly less on M3/4 than it is on M5. I`m also happy that M gmbh are finally ditching those sliding cals. |

I may be in the minority when I say this, but I could care less how much more power this new M has over the S65 variant (415, 430, 455 blah) ... as all M cars make more power than their predecessor. I won't consider ordering one until the sedan is independently weighed. Anything south of #3400 and I may tell my son he can pay for his own undergraduate and graduate school like his dad did! Crank HP won't impact that decision, sadly. I must be getting old...

The M5/M6 CCB's use the exact same calipers as the stock versions, just different pads and discs, and down rated booster. I hope M3 goes the same way |

very highly doubt it.
Its larger than the outgoing E92. E92 335's are around what 3700 lbs on a good day? edit: just saw the weight comparo's. I don't think it'll be under 3500 for sure. |

The current V8 S65 is already lighter than the previous gen. E46 M3 I6....
But I'm sure they will reduce weight where they can. Target = 300 lbs. less than current E9x

No wonder, S54 block was made of cast iron, with the S65 they moved to alu-block, that helps on the weight...

Turbos, piping, intercooler etc ads a ton of weight that would offset any differences from losing 2 cyl and some displacement. I seriously doubt it will be 3400 wet regardless.
