I'd say look at one of the Prius, maybe the Prius V if you need a lot of space. It's practically a minivan and yet it's easy to get over 50mpg in it. The normal, mid-sized Prius actually has more passenger-compartment volume AND luggage space than a Camry, though perhaps not as much legroom, and the V is cavernous inside. Otherwise, a Chevy Volt could be a great option. A member here, Cowmeat, recently picked one up and is getting close to 50 miles of electric range, and probably hasn't burned more than a gallon of gasoline since he bought it.
