Yep.
I originally didn't like how complicated the propulsion unit is but have to
admit that it works.
At heart I am a BEVer and have two I converted/built myself but the Volt/Ampera
really does do what it was purchased for.It completely replaces an ICE car and
I rarely if ever fill it up as the range is enough for daily commuting, even
weekends.

I like to win an argument? LOL!
I post an article speaking of all the confusion on how the volt works and
citing a GM engineer to clear the mud.
So you come back with auto news that contradicts the GM engineer.
