In straight line acceleration, has anyone been able to break traction (squeel wheels, burn rubber, etc...) on all 4 wheels at once? If so, what were the circumstances? I am trying to settle a debate and any help would be greatly appreciated.

Since this is on the A6 forum, are you referring to any particular models or just anything with quattro? I have seen bone stock new S4's peel out all four with authority on slick concrete (not wet). I can roast the fronts on my modified 5KTQ anywhere, we'll see if I can do it with all four when I put in the Torsen diffs.

Essentially, if you have the right tires you shouldn't be able to do it. However, with stock tires and enough horsepower (and a manual transmission) it is possible in extreme circumstances. The older quattro systems couldn't spin all four because they had open diffs (unless you locked them). The Quattro IV cars can do it if you have enough power. The TT does not have enough power stock, you will only shred the clutch (seen the results!!).

I would think that an A6 2.7T 6spd stands a chance of spinning all four if chipped, on concrete not asphalt with stock tires, at a 4K rpm launch in first. However, the clutch may not grab enough to do it. Higher revs at launch and the clutch definitely will not grab.

My 4.2 will not do it even in the rain. It just lauches you. It maight slip a little but I can't tell. I would think something bad would happen if you dropped the clutch in a manual at 4K with over 300 hp and quattro.

Friggin "Exhibition of Acceleration" tickets what a joke. Might as well be "I hate the color of your car". No, I have not gotten one of those tickets . . . yet.

If you have stock tires (not the optional A6 4.2 tires) then they will slip on smooth pavement before you break anything. I'm not saying that it is healthy for your clutch, and I would advise slipping the clutch instead of dumping it. My car has over 200K miles on it and it doesn't care :-)

86 5KTQ - currently turbo is taken out while chasing an oil leak.
