As mentioned, turbocharged cars do have some reputation for rev hang. But it's hard to say under what conditions it'll be worse and when it won't be as bad. On our new WRX, rev hang is horrible on the 1-2 if you're hurrying it at all. But almost completely absent if you aren't, and unnoticeable between other gears under . . . let's call it "moderate enthusiasm" using maybe 80% of redline and shifting carefully but reasonably quickly.


On re-reading Midblue's original thoughts it also occurs to me that if NLS was calibrated more for the straight line crowd it's not going to suit the corner-carvers - or those who drive less "brutally" - nearly as well.

When the revs are intentionally held higher than the next gear requires, you gain a brief acceleration spike as flywheel inertia converts to additional driveline torque as it decelerates to the rpm that matches road speed. This spike is also what helps you chirp the tires on a harsh upshift. But it isn't particularly useful at autocross or out on the big tracks where smoothness is the preferred quality and where reducing shift time to some absolute minimum normally isn't all that important.

Well said.
