Weight of options?

Anybody have a good idea on what the various options contribute to the curb weight? I'm sure BMW knows exactly how much each adds, but I doubt this information has been published. For instance, on an E90 I'm wondering how much weight the sunroof, heated/lumbar seats, fold-down rear seats, electronic damping control (or just the Tech package), and enhanced audio add to the car. Those seem like the most likely candidates for porking the car out. Even if it's only 10 pounds here and 20 pounds there, that could add up to a much heavier car.

What I'm getting at is, I would rather order a car with very low options if this stuff adds a lot of weight since it seems like every '08 out there is loaded with options. I don't mind all the extra gadgets but I don't need them and I'd rather have a sharper performing car, but if it's not a big weight penalty then I'll consider one of these leftover '08's I'm seeing.

If there's already a thread on this, by all means just direct me to it if it has the information in it, I searched and didn't find anything.

Thanks

sunroof is probably ~50lbs
heated/lumbar seats are probably negligible difference
Fold down seats are probably ~40lbs
EDC is probably negligible
Enhanced audio is probably less then 25lbs

this is the reason I ordered mine "stripped." It's supposed to be sports car, not a limo

The sunroof seems to be the biggie. Not only is it apx 50lbs on the E92, but the location couldn't be any worse.

Yeah, I could imagine it's a big penalty on the E92. I wonder what the difference is on the E90. I would think the CF roof makes around 10 pounds of difference vs. a plain steel skin just as an ass-pull guesstimate. Sunroofs are definitely the worst place to add weight to a car unless you put 50 pounds on a 10 foot pole mounted to the roof.

Negligible isn't negligible if it's more than 2 pounds IMO. If we're conservative about the estimates that seriousm3 posted, we just saved 100 pounds by leaving out the sunroof, audio, and fold-down seats. My gut feeling is that an E90 M3 with every option could weigh as much as 200 pounds more than a stripper with no options. I have an idea of what all the little googaws weigh by themselves (I've had a few of these god-awful BMW's, lol) but I have no data whatsoever.

Let's be realistic; we're not talking the e30 M. Any way you slice it, the e9x M is a big and heavy car. A few pounds here and there (with the possible exception of the moonroof) is not going to be noticiable.

Depends on who's driving. There's a reason no-options E36's and E46's are sought after by a certain group of people, and not all of them are trying to build racecars.

When adding lightness costs LESS money, that's a no-brainer to me.

The big weight contributor is the safety regulation equipments that need to be added to the car. I am sure that any company, including BMW, did some study on the marketing, cost and profitability. It looks like majority of the current new M3 owner (or future owner) prefer the amenities and options that are added in the current model. Let us face it, company needs to earn and survive and they want to maximize their profit.

I think I remember reading that the CF roof is worth 11 lbs over a steel skin so that's a good guess. I skimped on a lot of options with weight in mind, and the money savings is nice too. Honestly, there isn't anything that I really wanted that I did not get anyways. I like keeping things simple. Both of my cars are 6-speeds and neither have moonroofs.

if you re giving such thought to the weight of options, perhaps look at another car...there are much more raw sports cars than the m3. unless four doors is what you need.

Why would the fold down rear seat add 40 lbs over a fixed rear seat? Its the same seat structure isn't it?

The theory behind fold-down seats making a car heavier is that the lack of a bulkhead in that area means that additional weight has to be added to the seats to pass crash standards and the chassis to maintain stiffness. Could be lighter on the M3, I have no idea, but that's why they have caused a weight penalty in the past.

Disagree with that. However, depends on what you mean as negligible. You have the following differences between non EDC cars:

-Shocks/Struts
-Acceleration sensors
-Wiring harnesses

I'd guess at least 10 lbs. Really depends on the shocks/struts

Yeh, I suppose if you plan on tracking it heavily. There is absolutely no way, you or any one else is going to feel a hundred pound weight difference while driving on public roads, spirited or not. As far as your "lightness costs less" comment, it's because you are recieving less of those options that categorize this as a GT vehicle. (minus the sun roof). There is a multitude of vehicles on the market that are faster, more trackable, more throwable, and far trimmer than the m3. This is however it's best attribute, above average performance joined with daily driver luxury.

To give a general idea about weight of options, the lowest weight I've seen was a member that posted 3540 lbs for a AW e92 with the only option being 19s. That's with no driver and full tank. I think that's the lightest configuration possible for a stock M3. For comparison, Edmunds got a 3590 curb weight with the following options:

19-Inch Wheels With Performance Tires, Park Distance Control (Rear Only), HD Radio, iPod and USB Adapter, Premium Package, Technology Package, Cold Weather Package

I think the only things left off were sunroof, which we do have a number for and power sun shade and enhanced premium sound which I'm not aware of numbers for.

Yeah, I figured the "real" curb weight without driver would be somewhere around 3500 for a no-options car so that doesn't surprise me. I'd be very interested to see the results on the same scales with known fuel loads. I can't remember if Edmunds does full tank or empty tank or what when it weighs cars.

Ronin, want to come over to the shop and put your car on my scales?

I just might have to take you up on that. I'm targeting ~3580 after a few changes from the weight savings thread.

those 2 posts say it all in my opinion...the M3s purpose is to be a great daily driver with all the nice options/features while still being able to track it and drive it hard.

Spoken like someone who bought a convertible! (I kid because I love, if I didn't want 4 doors I'd own an E93 in a heartbeat...)

And, with all due respect, the purpose of an M3 (or any car) is whatever the owner wishes it to be.
