I do understand that it is difficult for a linear torque curve for a normally aspirated engine but to get there, BMW M engineers made design decisions to affect the engine's volumemetric efficiency to be better below 6000 rpms....decisions from intake runners, cam shafts, timing etc.

I would prefer that they didn't get this linear curve and opt for the VTEC like bump after 5000 rpm as it would be better for acceleration. I would sacrafice drivability (which is best with flat torque curves) to get faster acceleration.
