Just returned from test drive my A6.
While driving: 1st press of the button = traction control off. Yellow warning light displayed in the speedometer gauge. Floored it and smoked all 1st gear TM kicked in when shifting into 2nd.
2nd press = competition mode on. Yellow light not pressent. Floored it and again it smoked all 1st gear, however TM was hardly present when shifting into second. Car was going straighter?
3rd press AH/TC on.
Hold down a few seconds, AH/TC off. Yellow warning light. Again all first gear, medium TM intervention. My psi is 33 cold. During test drive it was 35.

<snip>...This highly experienced race driver actually turned his best lap times with the car set in competetive mode! He said that it felt slower to him but that it actually turned out to be faster. Chevy has done a masterful job with the electronics on the C6.
Yah, I had this little observation too at the track. The difference in driving is the fun factor sliding the car around provides. However, you can drive faster with the comp mode off as long as you are powering the car through the turns and not sliding around them while waiting to accelerate. That little slip that occurs is a nasty feeling when you are getting full throttle, but if you can adjust before it oversteer's just a weeeee bit you can keep it straight and power down to the ground.
Ironically, if you are on the back side of the traction curve, letting out of the throttle will give you lift and cause you to spin, more so than if you would just stay in it...slip angle
The second push should result in the display saying "Comp Mode" or something like that. It is awesome for track events. I went into an S turn way too hot, car got sideways, and the Comp Mode then says..."hey stupid, you can't drive, but I will fix it for you". You can feel the AH reset the car's direction to where I wanted it, and away I went, sailing through the turn (but did lose some precious time). No value on street, but on the track....awesome !!!
I would definitely leave that traction control and active handling on especially on public streets.
The street is a whole lot different than a purpose built road course and an error or unanticipated event at speed can quickly convince you of the value of the pre-need plans your local mortuary has available. These cars are wicked fast and will get away from you in a hearbeat if imprudently driven. Leave the TC and AH on during street driving. Respect the car for what it is, or it will bite you.
I always ran my 99 at the track in "competetive" mode. I could feel the difference during hard acceleration. I assume my 06 will also run best in this too. When I get a few more miles I'll find out.
The c6 tc/ah is very different from the c5. I experienced a couple turns at watkins glen, turn 7 and mildy on turn 8 where it drove the ah nuts. Turn 7 transistions from a smooth patch to a rather rough patch at an increasing angle to the right causing ah to activate the entire time during the turn to the point where it was either cutting power or appling the brakes so hard the car felt like it was bucking. I tried for 2 days to take this turn without the ah kicking in but no luck unless I was very slow approaching the turn. Once the tires where on smooth asphalt is was ok and I could get back on the throttle. 3 c6's there experienced the samething to different degrees(c6z06 not as bad) and the 2 c5 z06's I had the pleasure to ride with never had any issues on this turn.
