i have a Prius, in fact, have purchased 3 of them and still have my 2006. total nearly 100,000 miles on them and no issues. not one. now being able to dump the current battery pack and putting an EESU in its place would be awesome. i am guessing that an option for multiple EESU's in one vehicle would be probably beyond my financial means plus it would be priced in the premium "long waiting list" market, etc.
as far as the Volt. my personal feeling (no real info to back this)is that the Volt was supposed to be introduced in spring 2008...didnt happen. now its coming 2010. the EESU was supposed to be out. didnt happen. now if GM had been counting on EESU as its power train and there was never any real development with the Li-ion (after all, would there not be prototypes running around this close to launch dates?)
anyway, we shall see soon enough. but lets face it, the Volt is over priced, under-performing and simply too late with the "expected" technology.
Zenn proposing a "energy storage research facility" next door to GM is convenient. if they are looking for a place to rapidly expand a production facility with a favorable tax climate, Michigan is definitely a good candidate for that.
