So Im thinking what's the difference between their AWD, the nissan Gt-r ALTESSA-ETS AWD , Evo Super awc, Super Handling awd by honda.I think this is more complex, or maybe what's the diffrence in the torque distribution of these 3. I know the shawd of honda sometimes has a zero torque in one of it's wheel which I don't know if evo do that too.

All I know is the GT-R can distribute up to 97% of the torque to either the front and rear wheel.

i think all of them are capable of distributing the torque from front to rear, left to right but the SHawd of honda can do zero torque in the inner wheels while cornering, we will see that in the new NSX and the LF-A(rumored toyota will use it)

i can't find the video presentation for the other 2.

SAWC can do 50/50 front vs rear, and is also smart enough to give the most power to the wheel that's turning the least.

Well since we already know how the S-AWC in the Evo X works.
