Shift speeds.
Lexus is claiming 1/10th of a sec for up and down shifts on the IS-F. is this fast? I remember hearing that the audi DSG can do it in 1/60th of a second, but I'm not certain about that number. How fast does the BMW SMG shift?

The SMG transmission will up shift in about 80 milliseconds in the highest mode (S6).
You do raise an interesting point. Compared to other car manufacturers' transmissions, the estimated time for the IS-F's shifts are not as fast.

Well Lexus never said precisely what are the shift times. 1/10 could be 0.100 seconds or 0.189 seconds. Same like Fat Free candy that actually has 0.90grams of fat
It doesn't really matter anyway because it will still be fast as hell!

umm the isf is not dsg
anyway imo .1sec shifts are 'fast enough'
at that point i would be more concerned about the delay
ie how long does it take for the shift sequence to start after you pull the trigger for a new gear?
