M2 anticipated weight?

My M4 is apparently somewhere around 3,500 lbs. One of the things I loved about my prior 1M was that it was approx 300 lbs. lighter than that, which I could definitely feel every time I drove the car (along with the shorter wheelbase). I also understand that the M235i (upon which the M2 will be loosely based) is similarly around 3,500 lbs.

From what I have read, the M2 is expected to be "significantly" lighter than the 235, but what do the experts and "insiders" say on this issue? I am hoping that the lighter weight, shorter wheelbase, and maybe a warmed over tune will strike the perfect balance between the M4's freight train thrust and the 1M's responsiveness and nimbleness. Not to mention the exhaust note...

Doubt will be much lighter... as won't have all the CF treatment the M4 gets....
Also will have bigger wheels and tires which won't help either...

maybe 200lbs lighter if at all....

Both good estimates, in my opinion. I propose we set the over/under at 3,350. Place your bets, ladies and gentlemen...

Where did you read that it'll be significantly lighter? I'll bet you it won't be, and it won't be because it doesn't have a CF roof. That really doesn't save that much weight. It's just that the 2er with an I6 is decently hefty to begin with.

My prediction is 3400 lbs with low options. I'd be happy if I can get it down to 3300-3350 lbs after some mods

Here we go again, M2 weight thread. I don't think it will be significantly lighter than the 235i but we will know soon.

Could even be heavier, it's bigger that's for sure so where are they saving the weight? Are the M3 parts lighter? If so it can't be much, it's not going to be some stripped down lightweight, remember it needs to be a sensible price, the one thing I’d like is a bigger fuel tank!

Juggling with curb weight

The Porsche Cayman GT4 features stock a fuel tank with a capacity of 54 liter. However, Porsche offers, for the GT4 only, free of charge a fuel tank of 64 liter (Porsche option #085). So that's a range extender bumping the fuel capacity from 54 liter (14.27 gallons) to 64 liter (16.91 gallons), i.e. 10 liter (2.64 gallons). Except if mistaken, the larger GT4 fuel tank has no impact on boot space. I guess Porsche will have a race-track related explanation for this smaller/larger fuel tank offer.

On the other hand, the offer might have an additional reason. As we know, the official curb weight (unladen mass) figure includes weight of fuel at nominal tank capacity. Hence, for the official GT4 curb weight figure, Porsche only needs to take into account the weight of 54 liter of fuel (instead of 64 liter) ...despite the fact that most GT4s will likely feature the optional 64 liter fuel tank.

So BMW, fit the M2 stock with a 30 liter fuel tank and offer - free of charge - an optional 52 or 60 liter tank, to further reduce the official curb weight figure.

A gallon weighs what, a little over 8 lbs., right? So at a 2.64-gallon difference we're talking about a rather modest 21-pound difference with the full normal tank weighing 21 lbs. less than a full extended-range tank. Seems like a lot of work on Porsche's part if they are just trying to get their registered curb weight down by 21 lbs.

Isn't the 1M slightly lighter than the 135? I think they did this with the combination of no moonroof, the aluminum suspension from the M3 and and I believe they took out a lot of sound deadening material. Seriously, I can hear every thud, thunk, clink, bonk, snap, pop and other noises from the 1M underpinnings. Definitely not a quiet car. I hope they do this with the M2, contributes to the hard core feel of the car.

I don't see where this 200 lbs weight reduction will come from that people are predicting. The only major savings are no sunroof and aluminum suspension parts. Brakes will be larger and heavier. More cooling. More bodywork. Bigger wheels and tires.

Yes but otherwise the official weight could be higher than the Cayman GTS. All other Caymans come standard with the larger tank.

Not to me. When I drove one, I thought its handling characteristics belied its advertised weight.

It's a bit front-end heavy. I think if you reduce the front by 30-50 lbs it would be perfect. It is a very nimble car but you can feel the weight a bit when tossing it around turns.

I thought that also made the 1M feel more "alive." I almost feel too insulated and cushy in my M4 (although I know I shouldn't complain), even with sport plus suspension and throttle settings.

I don't expect any weight reduction.
Sorry I don't see where BMW can save weight without making the car a lot expensiver.

Brakes will be at least 20lbs heavier.
Suspension, differential, bigger wheels again 20-30lbs.

We can be happy when the M2 has the same weight as the M235i.

The problem is a manual M3 weighs 3540 lbs.
The manual M235i weighs 3505 lbs.

That's a 35 lb difference. That sucks.

BMWUSA.com lists the curb weights of each car as follows:
  • 435i - 3600 .lbs (manual) / 3635 .lbs (automatic)
  • M4 - 3530 .lbs (manual) / 3585 .lbs (DCT)
  • M235i - 3505 .lbs (manual) / 3535 .lbs (automatic)

I'd guess that an after-market carbon fiber hood might save 30-50 lb.
But the front ride-height might increase a tiny bit.
