Nowhere near as extreme in measures as I first thought or what I have heard Audi are intending for their S5 Lightweight with it's extensive use of aluminium and carbon fiber, but then again it does need more help with weight reduction than the M3 did.
The information on the weight drop differs quite a bit. It seems like 100 kg at least, but some say BMW managed to drop another 80 - 100kg. Seems like we need to wait a little more until knowing this for sure.
