Something I never tried
Lets say I take my IX and gently drive onto a ramp that has rollers on it. The front of the car goes up the ramp until it hits the rollers. Obviously the front wheels will just slip when they get on the rollers because there is no friction - will the rear wheels push the car up past the rollers or will it wait a second while it figures out "wait a minute, the front wheels arent grabbing" and hesitate.
I saw this video and this is when I thought of this.

wow, that is a really informative video. it probably safe to surmise that because of the transverse layout of the evo, and taking into consideration the unequal front axles we would suffer from torque steer under icey, climbing conditions lol.
the conditions of these experiments are rather extreme

Correct me if I'm wrong, but doesn't mitsubishi's system work backwards from the other systems that selectively power the non-slipping wheels only when a slip condition is detected.
I was under the impression that it operated like a truck in 4wd mode except when you go to steer, the system selectively unlocks the multiplate clutch pack in the active center diff to allow the wheels to spin at different speeds.
As such, there's no power to "send" anywhere because all 4 wheels are always powered. This would mean that in a straight line (such as that test above), the evo awd system wouldn't even need that momentary pause to "detect" the slip and send power to the rear since the power would already be there.
So you get the best of both worlds, the traction and stability of 4wd locked mode and having the computer manage variable states of unlock when cornering.
