GM didn’t reveal all the details until the patents were submitted. The mechanical drive portion makes perfect sense.

Yes, you are absolutely correct and I think they did the right thing. Why sacrifice 15% efficiency? The Volt is a winner and it's killing many on this site that the damn thing works as advertised. I know many don't like GM because of the bailout and I wish GM had a standard Chapter 11 bailout. But what's done is done and I wish GM, Ford, and Chrysler all the luck in the world. We need to keep manufacturing alive and well in the US. Not everyone can work for Google or Apple. We still need base manufacturing and the Automobile Industry is a big part of this.
