Hi everyone,
I was flipping through the Canadian specs again as well as a sales support manual, (NO firm pricing in there so don't bother asking), and noticed the torque vectoring was only with the rear wheels. I seem to recall from earlier literature, (S-AWC literature with some vector diagrams in it if I remember correctly), indicating/implying that the torque vectoring could be done on BOTH the front and rear axles. Anyone else remember/know? (My memory isn't the greatest but...shrug, I figured if anyone would know, it would be here!)

the ayc is only on the rear wheels

 

Vectoring torque on the front axle would probably unsettle the car significantly. That and there is likely no room to place an electronic clutch in the case, at least right now.

 

It is my understanding that the ayc is an electronic overide of the rear diff, but that it is not the diff itself. The front and rear both have limited slip diffs, which will transfer power left and right depending on which wheel has the most grip. The ayc is, yet again unless I am misinformed, an electronic overide that can manipulate the power transfer characteristics to help the rear rotate and prevent understeer, or oversteer if the car gets out of control.

 

The front diff is a helical mechanical torque-biasing LSD. The rear diff is an active electro-hydraulic torque-biasing LSD. No difference between literature and actual.

 

Hey thanks guys for straightening/explaining it! I KNEW this would be the right place to ask
