While I have the feeling you have more experience in this area than I, I think your counterpoint may actually have supported my original commnents. Unless you are going to be racing the '01, most owners will not see the benefits of the new motor during average driving unless BMW decides to change the gearing between now and delivery.

The two engines will drive very similar in the RPM range of the current Coupe. The new engine should have better throttle response and acceleration but that should be a change of degree not magnitude. This all changes however as the current redline is exceeded.

I don't agree at all that the raised RPM limit is only of value at high speeds. There are significant benefits in any gear at the higher RPM, this is because the cars power out-put or horse power is significantly higher. hp is a very useful measurement of power out-put. The longer you maintain torque as you increase RPM the greater you power output. That is why people say that for race cars it is better to have peak torque at higher RPM, because this results in greater hp.

A comparison of 0-60 times does not get at the heart of the matter unless both cars have optimized gearing for 0-60 based on their respective RPM limits.
