E92 M3 = ??
With an estimated 114 HP extra on the M3, I can only hope the new M3 is below 1600kg, but I realy doubt that............................

A CF roof may only save 6 kg (13.2 lbs) over a steel roof (probably more, I'd think) but there is about a 50 lbs savings between a steel roof WITH a sunroof (plus motors, track, etc) vs. a CF roof.
So compared to a 335i coupe that weighs 3570 lbs or so, the M3 should saver 50 lbs on the roof, 10-20 lbs on the aluminum hood, 10 lbs PER CORNER on the wheels and tires (forged 18", hopefully), and maybe a few more lbs on lightweight aluminum fenders, less sound deadening, etc.
I doubt the brakes will be heavier than the 13.6" monsters on the 335i, so that weight should not go up by more than a few lbs. And the aluminum V8 weighs about the same as the E46 M3's 3.2 L six, and probably about the same as the 3L turbo in the 335i (when you factor in the weight of the turbo, intercooler, plumbing, etc.)
3570
- 50
- 40
- 20
= 3460 lbs
They may add some weight back with a stiffer structure, but hopefully this will be negated by lighter seats (manuals vs. standard power seats in 335i).
I think the rumor that the E92 M3 is supposed to weigh no more than the E46 M3 may be true. Now everyone close your eyes and imagine your E46 M3 with a screaming 420 HP V8 . . . mmmmmmmmmm
