I don't know what people mean by "good bye 'proper' high reving m car" It's not like the redline on this thing is going to be 5500.
If I recall correctly, the original M3 had a 7200 rpm redline. I doubt the new one will be much less than that. Probably will be quite close to it.
If you had all the people bitching about "not high enough redlines" I am sure you could put black tape over the tach and they would never know the difference.
My lowly yet very satisfying 330i doesn't rev much past 7000 rpm, but it is very entertaining and responsive.
