Maximum Bob talks pure EV Volt, battery-free Volt and prototype drives!
The other possibility that Lutz mentions is eliminating the engine/generator and going battery only. This is actually not a new idea and was discussed as a long-term possibility back in late 2006 when GM held the first background briefings on the Volt prior to its auto show debut. The idea is that if battery technology progresses to the point that a Volt type vehicle could provide a reasonable electric range without a range extender just by using a bigger battery, it could easily be done. The idea is mentioned in the first E-Flex technical description I wrote here. Finally, Lutz indicated that within the next two weeks he will be taking an initial test drive in a real Volt prototype. According to Scott this is an actual Volt prototype not a Malibu-based mule. I find that unlikely at this stage. A mule drive is almost a certainty though.
Update: Rob Peterson at GM confirmed that it is only a mule that Lutz will be driving. Actual Volt prototypes are still many months away.
