I do believe Subaru made this video, so its a little bias ...

A very interest video nevertheless ...

the Legacy should have alot more power then the Passat...

and its a known fact that CR-V's so call "4wd" never works lol

I'm curious on how CR-V's 4WD works. Most of us know that the so-called "Real Time 4WD" is front wheel drive under normal driving. Shouldn't it transfer at least some power to the rear when the front loses traction? But it doesn't look like so in the video.

It does, but not enough to get the car moving.

For those who know 4WD/AWD, then you know many 4WD aren't really true 4WD.  Just like 2WD aren't true 2WD.

Open diff vs some kind traction control diff.., but they aren't all build equal.

Eg. the Jeep Grand Cherokee Quadra drive is one of the full time 4WD system that can move 100% torque to one wheel when necessary.  I was able to use that feature for going off road and climb rocks and stuffs.

Then when looking at many of the other stock 4WD system..., most of them suck big time, until they modify their Front/Rear differentials.

What I am saying is that many AWD system out there only transfer 10%-15% torque from the front to the rear, which is far less than enough to move the car forward in many cases..!  It's probably not a big deal for those who live in Richmond, but it's probably a big deal for people who have to drive in the snow or ice, at places with hills..!

You know, it would be nice if we can do our own test at some sort of event to test out our AWD/4WD system  =(

呢個因為拍攝局限, 室內同室外光差太大.
