Here's a direct link: Greenest | Greener Cars Our beloved Prius c made it at 4th place, in the middle of the top 5, which are all electric cars. Following that is the Prius plug-in, and the Lexus CT (although the CT's mileage figures don't seem to be correct).
glad the 500e is there, really saving the environment. in that list, the c should be number one, based on quantity on road.
