Ford, in a strange way, does actually try to predict the future. If the FEH/MMH is driven into an area of sub-freezing weather then the level of regenerative braking is significantly REDUCED. This is done to protect the driver against the potential for loss of control due to FWD "engine" braking should an ice patch be encountered. They also disable regenerative braking anything you are using the brakes and ABS activates.
According to the Ford documentation, AWD vehicles engage the rear wheels as the vehicle comes out of a turn, to provide traction. Can't say anthing about the technical details, but that is what they say.

The regen braking is also suspended if the ABS activates.

BTW, I had a CR-V formerly, AWD, which I had in all sorts of nasty weather, and had no problems. AWD, of course, does not help when slowing, only when getting started (and occasionally as needed when the front wheels slip).

I'm afraid I haven't read of any disasters involving the Grim Reaper traced to AWD and front transaxles. Cadillac prefers RWD because it handles better.
