There is a thread on another forum that mentions the AT being 0.2 seconds slower to 60mph than the manual (figures were from Autotrend / motor week). I'd say that difference is pretty negligible. something like a 30 - 70 when rolling would be a more interesting timing, as I'd say it's a little more "real world" (highway on-ramp to joining highway - of course depending on the speed limit on the highway). All good and well a car having some crazy 0-60 time but then having a really crappy in gear time.
