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 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.
