The trunk on the Altima is the smallest of all passenger hybrid vehicles, sitting at a hair over 9 cubic feet of space.

The Camry and the HCH offer 10 cubic feet of trunk space. Considering the size of the Camry (mid-size), the HCH has a subjective space efficiency advantage here since it is a compact.

The Prius does come closest to addressing your needs, does it not?

It just occurred to me that the Civic Hybrid has a flat rear floor. This flat rear floor is an often neglected feature that allows for some pretty beefy items to be carried back there in a moment of need. The only negative is that the front seats may have to be adjusted forward for "thicker" items.

I know some folks with wheelchairs in your exact same situation that have managed to carry the folded wheel chair upright and behind the front seats. Of course this means that you can only carry at most one additional person in the rear seats.
