Well you can get after-market modifications to the Prius that allow it to operate as a plug-in hybrid. The Volt will drive the wheels only from electric motors. The HSD on Toyotas is much more complex and the gasoline engine can (and usually does) drive the wheels directly).

Trust me when I tell you I understand your reasoning but it's the ability to capture and store energy that sets the Prius apart from the conventional car and regardless of the source, wind, braking or coasting, the Prius has the ability to run on that energy in it's stored electric state. If I too wanted to split hairs, I could argue that a Volt plugged into my house is coal fired because most of my electricity comes from coal. |
