I just saw that section at the bottom too. I'm really not sure how the credits are determined, then. The article doesn't mention why the Prius gets such a large credit, when it obviously did not make a 25% improvement on FE over the 2002 model. I also read a while back (on Edmunds, I believe) that US lawmakers would try and favor American cars with these tax breaks, so somehow I think CNN's article is a little confused. If anyone can shed some light on this disconnect, that would be great.
