their plug-in-hybrid "Energi" is in the same (broad) category, no?
(not saying it's as advanced or complex as Voltec)
what you wrote also makes me think that "OneFord" has something to do not 'endowing' a subsidiary brandlet
on another point,
I'm not sure Ford has had a really strong position on not having a particular electrified model(s) ... they
used to sounds like that
but now they're changing tricks with the hybrid-only C-Maxeses - in the U.S.,
while dropping the hybrid from the new Escape.
I'd like to see electrified drivetrains available on every model;
really like the little I've read about GM's eAssist;
also very enthused about Volvo's coming V60 which will have what I've called "Virtual AWD": petrol front, electric rear - Plus their very-cool-imho Pure-Hybrid-Power driver selections

and
have been pondering a lot about a more complete approach for Lincoln models...
...since at one time Fomoco was saying Lincoln will lead in alternative drivetrains in the Luxury segment
