.... say about the new 4WD system:
[I"Aiding Launch Control in its task of catapulting the 911 out of the gate is the new electronically controlled all-wheel-drive system. Porsche Traction Management was taken directly from the 911 Turbo and replaces the viscous coupling that was in the previous Carrera 4 and 4S. The system can vary the torque split front-to-rear in any ratio within 0.1 second and is only limited by the front axle's 295-lb-ft maximum. It uses lots of signals - like steering angle, wheel slip, and lateral and longitudinal acceleration - and, as we discovered on a special low-mu track, does a superb job of shuttling power around to make any driver look like a hero, even on a slippery surface. As long as the driver stays in the throttle, the car will also avoid the need for the stability program to intervene by way of the brakes."[/I]

Now it's a moot point.

When I was driving my C2S home after picking it up (it was raining most of the way home) I wanted to see how well it handled on wet pavement and I hit the throttle pretty hard coming out of a rest stop. I pretty much ended any desire I've had for a C4.

i found a video showing the differences between the 997 c4s awd and the turbo awd, really no differnce, the turbo had an advantage on compacted slick snow though. i forget where it was though, i'll post it if i find it.
rwd is better around the track provided you know how to get it to work with the engine out back. Awd really won't make much of a difference, just braking and corner speeds, exit speeds though can be done higher with awd than chasing the rear with the 2wd. just my experience with a nissan skyline gtr.
it's awd, in a straight line(like dragstrip) it's gonna be better if you know how to launch it...without the launch control...which is a bs toy anyway, i could launch a c4s better and achieve 1/4 better than with LC on.
as for daily commute on back roads, awd. it's more versitle. just in case you get the day that starts dry and sunny, then while at work it starts to rain, then changes to snow. unless you're a really good driver.
the carrera 997.5 has lsd as an option, might be standard on higher models.

I have a client who drives a 996 GT3 as his WINTER BEATER. Snow's never come off of it.
I asked him why a rear wheel drive for winter (as oppossed to the 'why a GT3 for winter?' DUH, cos I fekkin can!!)
he said: "AWD is for ******."
I laughed at that one.
Go for the 997mkII C2S RWD and call it a friggin day!!
Ps. this post has no real valuable content! just fun!

This is not an issue with the 997/997S. Rear grip is tremendous; there is no problem getting the power down even without the LSD that is now available in the US.
