When AutoblogGreen visited Bob Lutz's house for the Vectrix electric scooter delivery this week, GM's product development chief Bob Lutz gave us some pretty candid information about the Chevy Volt's progress. Take this tidbit, when Sam asked Lutz if GM has vehicles running with both the CPI (i.e., LG Chem) and the A123/Conti packs?

About a month ago, we spoke with Dr. Prabhakar Patil of Compact Power, Inc. about CPI's lithium-ion battery technology. We didn't want to miss the chance to chat in person during the SAE Congress this week, so we stopped by the CPI booth. The reason most AutoblogGreen readers would be following the fortunes of CPI is the company's work with GM on the Chevy Volt (CPI, along with A123 Systems, are supplying the test battery packs for the Volt. BTW, the Volt/Malibu mules are on the track) but Dr. P

We've spoken with Denise Gray, GM's director of Hybrid Energy Storage Systems (she's working to get the hybrid taken out of her title, considering the whole E-REV thing), about the Chevy Volt's batteries many times in the last year or so (read our talks from August 2007, November 2007, and January 2008).

While that announcement was slightly newsworthy because it signaled a small delay/shifting of the timeline. Whatever. The news that the lithium-ion-powered mules would still be on track to be driven at all was a good sign. Lutz has now confirmed to Reuters that those rides are still scheduled for July but then announced a delay of a different kind.

The other day, Dr. Prabhakar Patil of Compact Power, Inc. was up in Vancouver, BC for the Auto FutureTech Summit. While AutoblogGreen wasn't able to attend the show, we did get a hold of Dr. Patil on the phone for about 15 minutes to talk about CPI's lithium ion batteries and get Dr. Patil's perspective on what the future holds for electric drive cars. As many readers probably know, CPI is one of the companies delivering batteries to GM for the Chevy Volt, so Dr. Patil is in the center of the li
