Prius V and Prius C concept.

First off, the Prius V - a Prius station wagon of sorts.  Longer and slightly taller than the standard Prius.  Seems like it gained at most, a foot in length in rear storage with the rear seats up, and another foot with the rear seats down.

The Prius C concept appears to be an evolution of design of the Toyota FT-CH from last year. Practically everything is carried over from the FT-CH concept, which makes one believe that Toyota is testing out the ideas of a finalized design before going to manufacturing for a 2012 model.

I see a lot of influence from CALTY's designs of the Scion xD in the rear quarter, and I most definitely love the front end.  It looks a lot more refined than Honda's CR-Z, in my opinion.
