Sorry if this is a repost but: http://www.dailytech.com/Lithium+Technolog...article7503.htm I'd buy a Lithium Ion plug in that can get 100+ mpg . . .
<div class='quotetop'>QUOTE(bigj3347 @ May 31 2007, 02:52 PM) [snapback]452729[/snapback]</div> I don't know if that article is a repost though there are other plug-in versions that have previously been discussed. Personally I think that for Toyota to produce a Lithium based battery in the Prius it would have to result in double the efficiency without any increases in the price. If they managed a Prius III with 90mpg it would appeal to many more than it currently appeals to. However if that 90mpg only came after plugging in the vehicle that would complicate things a bit for the general public. As far as the article goes, it's a bit of a reach to claim that the new Prius won't have lithium battery because of a manufacturer defect on V8 camshafts...
