[
From BMW on SMG II:
Double Declutching
To prevent a fast downshift from upsetting the M3’s composure in any way, the SMG II will
automatically double clutch and raise engine speed on downshifts to guarantee that engine
RPM and road speed are perfectly matched before the lower gear engages. The result is
quicker, smoother downshifts with less wear on the clutch and less chance of upsetting the
car’s chassis.
So, who still thinks double declutching on a syncro'd transmission is a waste?
