yes, the Avalanche is more traditional 4-wheel drive.
It had some pretty impressive traction control tho.
In normal rear-wheel drive, if it sensed any wheel-spin it would transfer power to the front almost instantly.
No need to push the '4x4' button.
I tried to deliberately put it into a skid on ice: computer takes over & controls the skid using the 4x4 and individual wheel braking.
Don't ask me just how it works, but it does work.

The Subaru is all-wheel drive all the time.
For some reason the all-season tires on the front would push instead of steer on ice.
Once snow tires (Goodyear, I think) were installed, it was good.
But it would not correct driver error like the Avalanche.

I haven't had the Traverse through a winter yet, but we did have some early snow.
It is front wheel drive with rear drive assist.
Computer traction control similar to the Avalanche, but doesn't correct driver error to the same extent the Avalanche does.
Likely several factors at play: front-wheel drive & rear assist instead of rear-wheel drive with front assist and it's a much lighter vehicle, shorter & narrower wheelbase.
I'm thinking snow tires would be a very good idea on this car, just have to get used to the $1200+ price tag!

hmmm, seem to have hijacked the thread into a discussion about traction control...
