We haven't had snow yet, but winter is coming. And that is exactly where I used 4A a lot on my old truck. I'll have to give the Slippery mode a shot when the time comes. Thanks for the heads up on its potential effectiveness.At first I thought that was something I was going to miss as well, but having said that....
I haven't had the opportunity to fully test in situations where it matters, however, from a bad snow storm we got a couple weeks ago with 14" of snow that melted and iced up the roads pretty good I found the "Slippery" drive mode just as effective driving on ice and mixed ice/dry roads. There's a particularly badly crowned road I have to turn out on and in 2WD Slippery mode I had no problems whatsoever. Felt like it really put the power to the ground where in the 4A in my '13 F150 seemed to bog down more instead of get you moving. That and it was LOUD in my F150 although I think most of that was from the traction control.
