Torsen

[Dane]

A magical device called a clutch.

2017 have that??

Both that and mechanical locking.

I thought you knew everything about 4x4 because you live in Colorado , but yes it does.

4A uses a computer controlled clutch to vary output to the front anywhere from 0-50% of power.
4H is part time (locked) 4WD split 50-50 front-rear

My 2015 Silverado had the same thing, as did my 2004 Suburban. It's not new. New to the Raptor though I think.

I understand the varying output of power, but it's still leaving the front and rear locked together isn't it? Causing that pulling effect I think you are talking about where steering is more difficult.

I actually didn't know this was an upgrade to the 2017. Personally I'm not a fan of tech like that. I think it causes more problems than it solves. When I want four wheel drive, I'll put it in four wheel drive.

I'll concede I'm not up on AWD stuff, just standard 4x4.

This is my view, as well.

The good news is that you aren't forced to use it. Plain ol' 4x4 is still there and it's locked so it doesn't rely on the clutch holding.

It's a nice system when conditions are variable. You can leave it 4A forever if you want, you'll just potentially wear out the clutch sooner.

If it's just kicking in for rain, it sounds WAY too touchy for me. C'mon, rain?

Here's what 4 wheel drive is for...

It's not touchy at all. You won't even notice it if the wheels are straight, or you aren't accelerating, or you don't have the Torsen. You really have to look at the Power Distribution screen to see what it's doing.

I've been up the Eisenhower in a blizzard using 4A, the technology works. Wasn't near as bad as your pics, but there were some trucks putting on chains.

My point is, why is four wheel drive kicking in in the rain? That's what I meant by touchy. It seems unnecessary to me.

Because it's in 4A. It's doing what it is supposed to do. Like I said, it's somewhat similar to AWD and totally normal to be sending power to the front, even when dry.
