how does the 996tt AWD system differ from the 997tt ?

This thread should be a sticky. I never knew AWD and goat milk were related.
Would be awesome if other people can recommence posts on the AWD effectiveness of 996tt/997tt in rain/snow/low traction conditions.

Even more useful might be a thread on the different exhaust systems and free-range chicken.

The 996 awd system does work. My left rear hit coolant coming out of a corner, I'd didn't even know this until the next lap where I saw the coolant. But at the time I exited the corner and hit the throttle and instead of the normal acceleration you'd expect. I saw the PSM flash as the one rear tire spun, half the power transferred to the front and I thought at the time I just blew my engine. A few seconds later for the next corner full power returned, that's when I took a cool down lap to figure out what just happened as then saw the spill. AWD does work.
The 997 has an electronic AWD system. The computer works out when to transfer power to each wheel by monitoring wheel and yaw with sensors. It is very advanced compared to the 996 which is straight mechanical and not intelligent.
The engineers program the computer to manage the way the computer will control the system. 997.1 is their first gen and it's said to be a bit restrictive and early. 997.2 has a updated program which allows for a little yaw/fun before it starts cutting in. I am sure the next version will be even better and maybe will we see the ability to switch programs depending on what the driver says the road conditions are.

Is there a practical difference in rain/snow/ice traction comparing the 996tt and the 997tt?

In snow/ice the way the 997 AWD works, is very different. If you're used to the 996 it needs to be driven differently. With the 997 you basically stop using/working the steering wheel and just point and throttle.
Both have the same traction on same size/type of tires but it's the way it handles the traction. 996 with PSM on will just cut throttle to the engine and brake the wheels which prevents wheel spin. Turning off PSM will allow the rears to spin which will sent power to the front. 997 will do a much better job of integrating the PSM, ABS and throttle control. Leaving the driver with nothing really to do and feeling like there is more traction then there really is.

997tt is computer driven therefore in theory faster. In the real world they are very similar. Very difficult to feel the difference if you drive them back to back. I drove both and I'll be damned if I can feel any difference in dry or wet. As far as snow goes I have not tried that.
