I agree with swamp. The S65 is not "peaky". Peaky implies the torque curve is like in inverted "V". The new S55 is the more "peaky" engine.

What you feel in the S65 is like a locomotive: it keeps pulling with the same acceleration (mostly) all the way up to redline. The S55 will give you acceleration until it reaches 5500 rpm at which point it starts to fall off dramatically (IMHO). This will feel noticeably different then the E9x M3. I can see why swamp is afraid that the new engine will not have the same character as the old. It remains to be seen just how bad this will be.


Cheers.
