Not wanting to add more fuel to the fire, but not all "AWD" systems are equal. There are mechanical ones and there are electrical ones. And among those categories, there are many different systems with considerable variation in purpose, function, performance, and effectiveness. For example, the ZR1X corvette has a type of electric AWD, but it is very, very different from the gen5 prius electric AWD. And, unfortunately, the gen5 prius AWD does not appear to be super effective:
Good thing the roads aren't rollers....LOL. That's not a real life test. I've run mine pretty fast on snowy/ice roads in the mtns and it handle really well
You're correct about that, but nobody is saying that they are. Rollers are indeed a challenging test. But some cars with AWD are able to pass this kind of roller test with ease. Unfortunately, the prius AWD is not one of them.
The latest gen Camry failed the last test as well, and needed to be run in sport mode to pass one of the others. He concluded it’s good for some ice and snow, but would get overwhelmed by a lot.
Of course they are. That's their whole point: rollers are like slippery roads. Otherwise, why bother? My takeaway from the video? When stuck on snow and ice or other slippery stuff, switch to sport mode and turn off traction control.
