When Toyota significantly upgraded the Prius from 2003 to the 2004 car, will 2008 be another big jump? Anyone in the know think a plug in, switch to a different and better battery etc. be involved? So far, each year has just been cosmetic and I guess 2007 will be more of the same. If you know anything about what Toyota has in store for us, let me know!
If you want, you can do a search to read up on the threads. I can answer that it's very probably to your questions that you mention. I think "Prius & Hybrid News" would be your best bet.
