2007 Nissan Altima Hybrid Sedan 4dr Sedan (2.5L 4cyl gas/electric hybrid CVT)
Something not mentioned
 The fuel economy is tied to the battery efficiency, and the battery efficiency is highly ambient temperature dependent.  I found that below 35F I get 35 mpg as rated, worse if very cold.  However above 70F I can do mid-40 mpg on the same commuting trip.  My best record is ~49 mgp.  That said, economically it becomes a gray area to get this hybrid if you live in a cold region and drives mostly highway, a plain Altima may come out more economical.  Another thing is this car uses synthetic oil!  It was such a sticker shock with my first oil change.  Factor this extra cost in for a thorough car purchase evaluation.
