Low speed torque and driveability ?

Plus I question in relative terms are we really losing that much in the under 3000 rpms to be that concerned with especially when we spend fairly little time at full throttle under 3000 rpms?
And you spend little time at full throttle in the top 1500 RPM range. Probably spend more time in the off idle to 3000 RPM range at full throttle with aggressive driving. Even more important is part throttle like say 50% in that lower RPM range where most drive. That is where torque is a factor.
