Depends a lot on the hills. If the hills are so steep that you have to brake on the way down, it's often less efficient. But if the hills are enough to maintain speed in neutral or with light engine braking (just enough to get deceleration fuel cut off), you can often get better fuel economy than on the flat.
Driver skill comes into play a lot more on hills, and manual transmissions really shine in comparison to autos (especially on the way up).
Are your cars manual? If they are, what at what kinda revs do you shift up?
