It (7AT) shifts faster than the 6MT, when viewing the entire process...ie, let off gas, drop clutch, shift, enguage clutch + gas...

The whole process is faster.

I can see the AT edging out the MT in a 1/4 mile race, but not around an actual course/track. There's just not enough control with the AT for it to beat even a semi-competent MT driver. Not a knock on the AT, but that's just how it is.

I guess it'd depend on the track.

Even then the margins would be pretty small, I'd imagine.

Professional drivers do something called a clutch-kick shift, its a quick stomp of the clutch, pull gear through neutral, release and gas simultaneously, this can be done in a fraction of a second, so the "Auto is faster" debate is unfounded. Hell even I can do it, and im not exactly a professional, a little bit of practice and it can be done.

btw, here is a simple example, the music is kinda gay, but you get the point...

right around 4-500 milliseconds..

Thanks for that, Red. I also read, in Car & Driver I think, that they had issues with the 7AT not wanting to drop down 2 gears when requested. I can't see how the 7AT could best a manual on the track with a competent driver.

Seems to work fine for me, but, then again, I've yet to hit a "track" with it.

The manual's only advantage on downshifting is that you can skip gears easier.
