AWD vs 4x4

Saw this video and thought I would share it with anyone interested.

I have a feeling the author of this video is pretty uninformed and most of the advantages he lists are rather due to modern systems like traction control and stability control. Most earlier AWDs like the Honda CRV RAV 4 relied on a Torsen differential to mechanically engage when it detected slippage in the rear wheela. Like a LSD diff and much like a LSD over time that got worn out effectively leaving these cars as FWDs and 99% of the owners never reall went off the beaten path to realize that.

Now most decent new 4x4s are full time AWD along with the option of Selecting 4x4 or they have the option of 2wd,Auto and 4x4. with ABS, traction and stability control they work just as described in the video.

AND even today most of these AWDs use Torsen Diffs to save weight and costs rather than a transfer case like 4x4s, so even with all the gadgetry eventually they will turn in to FWDs unless the diff is serviced or replaced

Thanks for adding to the tread @desertdude. This is very informative.
