"Fielded" by itself isn't saying much. I recall the number of actual end-users (not GM or its business partners) who got NiMH EV1s was close to negligible, certainly less than the originals. But if anyone can put hard numbers on that, either way, I'll slide.
The Envia announcement was certainly curious... but then we heard nothing more. I wish them lots of luck, but so far it looks like, as they say in the computer racket, it's "coming in three to five years."
Still, batteries will progress, whether it's due to Envia or A123 or someone we haven't even heard of yet. And electric final drive is coming one way or another, regardless of what the upstream source is. An electric Fit is a relatively cheap way for Honda to keep their electrical people ready, for whenever a truly competitive cell technology is available. They just tag the program onto their existing Insight/Civic processes. The fact that it meets CA minimums sweetens the deal.
