lets try to make and educated guess of the weight of the M2 , DIN weight which I believe is all fluids , 90 fuel, no driver...

My guess for M2 Manual trans BMW will report 3,175lbs DIN / Actual real world weight will be 3,375

BMW reported 3,300lbs DIN weight for a manual trans M4 and in reality it was about 3,450-3,500 on real life scales

Winner gets all the beer they can drink

not light enough already won

Despite how much I wish otherwise, I highly doubt that it will be any lighter than a similarly-equipped M235i. It's rather unlikely that the weight-saving measures of the M3/4 will be applied to the M2, due to cost. If I am wrong, however, I will be pleasantly surprised.

[PopsnBurbles]

For the US market, I'd imagine it between 3350 lbs. and 3400 lbs. curb weight (full tank, all fluids, complete interior, and no passengers+baggage). That is for the manual car.

Add another 75 lbs. for the DCT.

[blefevre]

<50lbs heavier then a similarly equipped M235i

Weight savings (guess)
- Exhaust
- Suspension components
- Driveshaft

Weight gain (guess)
- Diff
- Cooling
- Wheelset/Tires
- Body work

[m981addicts]

Hopefully less than four mature male pigs. A comparable Audi is at least five(okay, 4 and 2/3).

Assuming 837.5 lb. porkers.

DOH! Well you are already wrong... so expect a pleasant surprise

the M3/M4 suspension is lighter. the control arms will feature more aluminum... not sure if the M235 has the solid mounted subframe... the wheels will be larger overall but more than likely overall they are still lighter.. Same with things like brake rotors ...

The weight savings from the 135 to the 1M was on the order of about 77 lbs IIRC.. So I would expect a little more of the same here..
100 pounds aint much.. but give credit where it's due..

[oldmanstyle]

I've always thought about 3380 lbs so I will just +1 the OP.

[chaddy74]

My guess is 3,280 pounds Auto or 3,250 with the manual gearbox.

This is probably going to be a bit long, so bear with me:

While you are correct that the M3/4 suspension arms are aluminum (I believe that the M235i's are stamped steel), keep in mind that the subframes were extensively re-engineered and stiffened to support them. Though I can't say for sure, without the actual weights of both subframes, it is possible that the M3/4's subframes are actually slightly heavier than the standard 3/4. The goal of the lighter suspension components is less overall weight reduction and more unsprung weight reduction. Trading a slightly heavier subframe for lighter suspension arms would still make for a dynamically superior suspension, even if the total system provides no net weight savings.

As for the wheels, a quick google search suggests that the 19" M wheels are less than 1 lb lighter than the M235i's 18" wheels. Though the difference is relatively small, they are indeed lighter, so you are correct. However, if the rolling diameters (including tires) of the M2's 19" wheels are larger than the 235's 18" wheels, the M2's tires will likely be heavier than the 235's, offsetting the weight savings from the wheels.

Rotors are a toss-up without actual weights; while the M3/4 rotors are floating (I don't believe the 235's are), they are over an inch larger in diameter than the 235's, which is a fairly significant amount of material. In addition, you have to consider that the calipers will be larger and heavier than the 235's, as well.

Finally, wasn't a major contributor to the 1M's weight loss the moonroof delete? With a number of spyshots showing M2 mules with sunroofs/moonroofs, that fairly significant weight savings can't be counted on. This is why I specifically stated "I highly doubt that it will be any lighter than a similarly-equipped M235i". Similarly-equipped would assume both cars with or without moonroofs.

While it is possible that the M2 will receive a CF driveshaft, similar to the M3/4, please remember that the M3/4 also has an aluminum hood, aluminum front fenders, CF roof, and CF trunk. I believe that I also read somewhere that the S55 had significant weight-saving measures applied to its components, as compared to the N55. These are a lot of things that the M2 is unlikely to get, due to the target price point and adherence to the 1M "formula".

The M3/M4 front fenders are plastic not aluminum.

[cwg]

According to the BMW USA site specifications on the M235i coupe:

"Extensive aluminum componentry, including front suspension components (forged-aluminum lower arms); subframe; steering rack; and brake components"

"Aluminum double-pivot spring and strut-type front suspension"

"Five-link fully independent rear suspension in lightweight steel"

I doubt there is a lot of weight to be saved in the front suspension - maybe a few pounds in the rear.

I just don't see where any significant weight reduction will come from moving to the M2 from the M235i - Hope BMW found some way, but does not appear from various reports that they will make use of much carbon fiber.

Let's say approximately the weight of 3 BMW Isetta cars.

[OrangeCrush]

3350 or less would be great. My guess is at least 3450-3500lbs.

Oh weight......

[135iDCT]

Unladen weight EU = 3293 lb (manual, standard equipment, 150lb driver, 90% fuel)

[JNoSol]

Manual M3 is 3,540lbs. Manual 340i is 3,665lbs. The M division was able to shave 3.4% off, use to lighter suspension/carbon drive shaft/components.

The M235i is 3,505lbs. If the same weight savings percentage applies, the M2 might weigh 3,385lbs. I'm guessing it will be closer to 3,405lbs.

That percentage won't work 100%, but should be close. The M2 is not getting the aluminum hood and CF roof. I also think 3400 lbs is right where it'll be, which is right on par with an E46 M3.

I'm OK with that.
