I actually don't know the name of this but was hoping to get a little more information. I purchased this 2000 A6 Avant with tiptronic and the 2.8 about two months ago and have been enjoying it completely.

I did have a question about this switch though. When you are driving normally in either the automatic or tiptronic mode there is a switch operated by the gas pedal that will cause the transmission to shift to the lowest possible gear (as per current RPM) so that you can have emergency accelleration. Its pretty nice to have to get out of people's way or pass if needed.

I'm talking about when you push the accellerator pedal all the way to the floor and then push some more. You'll feel it 'click' and then feel the gear change.

My A6 2.8 has it and my friends A6 4.2 has it as well.

So the questions? How often do you guys use this feature? Does it actually skip gears when its shifting down like that? I've seen mine apparrently drop from fifth to second at times. Do the 2.7Ts have this feature as well with their tiptronic transmission? It just seems like those turbos kicking in like that with such a jump in engine rpm will hurt the transmission.
