I think there will be an increase in gas mileage, however, it will not be noticeable. It will be very slight. You will see the increase because the clutch transferring power to the front will be open, i.e. no friction losses, but you still have the weight from the AWD system. It might be somewhere between an i and xi, leaning a little more towards the xi I would think.
Update on my status:
I am taking tons of data at the moment and trying to reverse engineer some things. I can see the light at the end of the tunnel. This is really getting fun
I.think that I might be working at this from a different direction to you.
