It's like AWD systems aren't even trying!

Do the rear wheels even do anything with these newfangled AWD systems? I'd be ticked if I got an AWD vehicle and it performed like all of the ones after the first Subaru. I'm glad I have part time 4WD on my 4Runner. Bonus: With the 4WD off, it's a RWD!

 

I’d say there’s more at play than what you’re seeing.

 

Fake news.

The systems differ quite a bit. In many lower priced vehicles (Ford, et. al.) the rear wheels receive torque that does not exceed the value capable of being delivered by the clutches.

When a vehicle is on an incline, more torque is required to move the vehicle, compared with level ground. The steepness of the incline (the video shows a very steep incline) can be chosen in such a way that certain vehicles "fail", while others "succeed".

Low cost AWD systems (Ford, et. al.) are principally designed to provide a small amount of traction in slippery conditions, for example in a small amount of snow on level, or nearly level, ground.

Any Ford vehicle that is not the Explorer or F-Series is not purchased for reasons of its "AWD" or "4WD" capability.

Fake news.

 

If I remember, the Rav4 of that vintage had a locking center diff. I wonder if they engaged it? As mtbpsych said, they is more at play that what you see and this is nothing more than a Subaru commercial.
