Correct, parent should have said EREX (electric, range extended) or EREV, but not PHEV.

The Fisker Karma and BMW i3 (well some of them) were this type of EV. My wife had an i3 Rex and loved it, though it irritatingly had only a 2 gallon gas tank.

Mazda was working on one but it never came out in the US. Supposedly the Scout EV will have a Rex, that would be nice.
