You might want to consider a Honda...

On the freeway at 70mph, HCH 2 can average close to 50mpg. I tend to keep it between 55-65mph and have average about 52 overall (20/80 city/hwy).

I dont know if the Accord Hybrid might also fare better than the Camry if you have mostly freeway miles.

Certainly, around town, the Prius/Camry tend to get better FE than the Hondas.
