When I engage snow/ice mode, does that lock up the rear diff to give better traction in bad weather i.e. similar to a locking diff on a 4 wheel drive truck?

No, you have a limited slip dif not a locker

On the SS (non 1LE) model the different modes have different software maps for throttle, NPP exhaust, steering and suspension (MRC on 2SS). The rear diff uses mechanical methods (clutches and friction modifier in the fluid) to manage the rear wheel engagement from side to side.

The one thing that makes the most difference in snow/ice driving is your right foot. Go slow and easy like you have an egg under your right foot. Of course since you live in Cleveland I'm sure you know all about that.

Haha yes, I do. The reason I asked is the other day I backed it out to get to something in my garage, and there's some ice and snow on the driveway. When I pulled it in it just spun the wheels when I hit the lip of the garage floor, just feathering the clutch not giving it gas. Then I engaged snow/ice mode and it got right up with no spinning at all, like it locked right up and dug in. And it's on the factory summer-only tires.

Traction control doing its job.

That's what I was thinking except doesn't it do it's job when in any of the other modes or it has a higher threshold of engagement in the other modes?

[Scottyz]

Yes it varies as per the mode you are in.
