I do not understand why someone would be interested in a performance car if they just cared about low to mid power ( this is what trucks and SUVs are tuned for.) But then again, why would someone buy a performance car with slush box. Lets say you take your 335i to redline in first gear, when you shift to second your RPM's drop to 4700. You are right at where the torque is just about to fall. This is why the turbo puts out tons more power in the mid range and not so much more on top. The 335i puts out 50% more torque than the 328 but only 30% more HP.

First of all, the 335i is underrated, so compare the rwhp ratings, and you will see more than a 30% advantage. Secondly, you do not drive around redline all that much. And if you did, you would most likely be getting less than 6mpg. So honestly, if you are getting better than 6mpg, you aren't that kind of "performance" driver to begin with.
Secondly, there are plenty of torquey sporty cars that don't rev that high, or have maximum torque around redline. Just look at a Porsche GT2RS Turbo. Doesn't even rev that high compared to a GT3, but with over 600hp, it will leave the GT3 for dead in any kind of acceleration contest. So feel happy revving the normally aspirated version, but I would take the faster version any day .
