Blunt is fine, self-rightous to the point that you tell another person who's quite knowledgeable about a subject that he's "wrong" is not so much.efusco,
I apologize if I am very blunt, but there are some aspects of product development / marketing that I feel are "do or die" essential, and I believe that differentiating the Volt from other hybrids, by designating it as an EV with a range-extender is one of those critical, "do or die" essential tactics for its success.
Here is an article from CNN (far from a technical source), which elaborates on the facility of the range extended concept, and the easy segue to hydrogen vehicles from there.

I'm quite comfortable with the entire concept of the range extender....clearly you like it. I see it as a propaganda tool to try to expand a difference that is fairly minor. As a marketing tool that's a good idea. As a tool to simplify a subject that can be difficult for the general public to understand it's bad.
