The commonly accepted definition of a full hybrid (there's no "real" definition of course) is a car that can travel using only the electric motor. I argue IMA cannot do this; it's been many months since the last time my car did since I gave up putting the effort into trying to activate it. Whereas a Prius just does it automatically. You'd never see posts asking how to activate EV mode in a Prius; it just happens.

That's debatable anyway. But yes, by "full hybrid" I mean HSD, Ford's system, and the Dual-Mode system GM/Chrysler/BMW is developing.
