The Honda AWD system uses a compact, lightweight and fuel-efficient rear differential. The design requires a certain torque limitation for the device to be able to work effectively in real conditions, but at the same time, it must not exceed the total capacity of the AWD drive.
So, the rear diff now can only handle 10ft-lb of torque? Even Honda motors today make more torque than that. Sounds like they are saying, if there is zero traction up front, you're SOL, the rear diff can't handle the torque available off-idle.

In other words Honda does not see that the roll test fairly highlights CR-V's AWD performance.
Of course they don't like this test--they failed it!

but I don't think it's that unrealistic to imagine a similar situation happening on an icy hill; where the rear wheels are on solid ground but the fronts are stuck on slippery stuff.
Nope, I can see that scenario. Heck, I've gotten stuck where
one tire was on ice, the rest on ground (usually it was in a pothole also).

Not sure what to make of this test, actually, since it's seems pretty hard to believe that Honda "forgot" to test the AWD bits. I'm guessing it works. Don't know why it doesn't work here, and I wouldn't want to buy an AWD system that failed like this. But it seems hard to believe that it would fail like this.
