Is the Volt miles ahead of the Prius

This Prius by Hybrids-Plus achieves more than 100 mpg, today

I just finished reading David Kiley's BW article, GM's Plug-In Push, which opens, "General Motors is developing a plug-in hybrid technology for its Chevy Volt that is miles ahead of Toyota and Honda."

Really?

I heard the same such sentiment several months ago regarding GM's hybrid vehicles, which many have called more advanced and more sophisticated than Toyota's hybrids such as the Prius. Perhaps, but still I have asked, what are the costs of GM's technology, will it be sold in a package that consumers want at a price they are willing to pay? (Finish)
