C6 A6 Question regarding Launch off the line and acceleration out of the turns
I just got my 06 with A6 and I am having trouble getting of the line and getting responsive acceleration out of the turns at a local autocross event this weekend. It seems sluggish almost like a hesitation. I had an 03 with A4 I autocrossed that did not have these issues. I tried S with TC control off, S in Competition mode, S with TC off using the paddles. In each instance the car just didn't seem to have the power of my C5 even with the additional HP and A6. Any help would be great. This very well could be me just not being familiar with my new car.
With 400HP I should be able to smoke the tires if I wanted to and rip out of the turns.

I'm not sure transmission tuning is available yet for the A6, but if not it will be available soon. Until that is hacked, you won't be able to fully get rid of the torque management.

Are you holding the car in 1st or 2nd gear? Will the trans stay locked in 1st or 2nd gear? Looking at the stock ratios, 1st gear is good for around 48mph, and 2nd for 81mph at 6500rpm.
If you are in a single gear, not shifting, there should hopefully be little torque management kicking in.
I can see it being frustrating with so many systems holding back the cars performance - GM needs to work on this, they are not building Buick's here.

Just playing devil's advocate here... it is first and foremost a street car, intended to be safe on the street, and somewhat accepting of a ham-footed driver...
But I agree, it is unfortunate that there are so many things to be overcome. GM uses track capability as a selling point, yet doesn't really make a track car...

Probably still better than a BMW or Mercedes where you can't turn off the AH. Just was reading my latest edition of the Roundel where they were testing the 5 series and they were wishing it was more like the Corvette.

Melting Slicks
I AutoXed a friend's A6 C6 about a month back on my 315 & 335 Kuhmo 710s.
First off turn both the AH & TC off. With those on at all it won't let you do jack. Second make sure you're in "S" then tap one of the paddles to make sure you are controlling the shifts. I found the car pretty responsive like this. I'd launch in 1 and brake-torque it as much as the stock torque converter would allow. It launched hard but really wouldn't spin the 335s (which surprised me a little, I expected to be able to spin them at will off the line). But it certainly came out of the hole nicely, no issue there.
The only times it felt slugish or unresponsive out of the turns was when I forgot to shift it back down to 1 in the braking zone for the tighter turns (I run a very fast AutoX series where there's plenty of turns well over 1st gear's top speed, but still a few that duck under it). That was mostly my lack of seat-time in the car and being used to a M6 myself.
Overall the car felt really good and impressed me for what it was (base model with C6 Z06 sway bars & shocks, and the R-compound mentioned before). The A6 isn't perfect, and I certainly would have chose the gear ratios differently, but you can make it work.
Just whatever you do don't let it think for itself...

Thanks for the input. I agree its possible to make it work autocrossing. The car handles like a dream with the great corning and braking capabilities due to the Z51 package. The biggest problem are the C5/C4 MN6 guys ripping off the line to the first turn. I am sure I can get more out of the car with seat time. Some of the isssues could be in how quite the car is it just doesn't sound like its going fast. I found this made the car hard to shift because I couldn't hear the engine until the RPM'S were really high.
