I make it a habit to do a quick google around the net around once a week or so to see if there are any rumours about the next generation Prius. After all, its been 2 years since I bought mine - there has to be something in the works, right?
Well, stumbled across something at digg.com today on the first whispers about the next model. I’ve googled a little further, and this URL has a decent summary:
http://www.greenhybrid.com/discuss/2008-prius-lithium-ion-and-94-mpg-us.6729.html
To spoil the surprise, they’re talking about a lithium battery (instead of NiMH), fuel economy roughly twice as good (which is pretty mind-blowing itself), and shaving a second or so of the 0-100km/h figure. Nice…… 
Only downside? The net gossip is talking about 2008 as a release date - and thats for the UK/US! Past experience has Oz getting their models another year after that. Sniff….
