The interesting thing about the FEH (as opposed to the Toyota) Hybrid AWD systems is that it is identical mechanically to the non hybrid. The Toyotas use individual electric drives on the rear wheel, which can over heat and shut down (although this seldom happens in the real world, from what I have read).

I have a feeling that Ford considers most of it's hybrid programming very secret, and chooses not to produce any documentation that explains their AWD drive routines and how they actually implement the AWD. Of course they publish any maintenance guides required, but that is different from the design of how the system operates. So about all we know is that the sales literature says that it is "intelligent" 4WD and adapts to road conditions, rather than reacts to road conditions. But this is really only implied in the sales literature.

Thus, owning an FEH means one has the documentation and driving experience to share with other FEH owners about Ford products.

wwest tends to spout Toyota information in the FEH threads, which is why he is on my ignore list - I cannot trust that any information he provides definitively applies to the FEH as opposed to the HSD.
