Just listen to the natural sound inside the cabin of the BMW 1M Coupé in this video: (BMW starts at 2:17)
It isn't as good/loud as in the past M3's, (because of the Turbo's, we all know that) but it has no ASD and in my opinion it sounds very good. That's what I want for the upcoming M2 (GC) (and for the M3/4 as well), but I fear there will be no choice when it comes from the factory, but there will and must be a way to turn that off.
