AFAIK, the motor system in a situation like this is simply dead weight.
The closest I could find are the US "highway" figures, which are 41-45-48mpg (gen 1-3).
Possibly also worth noting that the Prius doesn't use an otto-cycle engine - which goes some way to explain its efficiency and relatively poor power output for its displacement.
I just get the impression that they would have liked to build a pure EV, or a "proper" hybrid, where the engine simply drives a generator. As I said before though, I understand that everyone was massively hampered by the restrictions in available batteries.
I'm not sure it's realistic to compare the prius to a hummer, the hummer is far from an average or common car. How do you figure the emissions for the hummer? If CO2 it should be proportional to the fuel consumed. If NOx, SO2 etc, then fair enough.
The hybrid system works at all speeds and applies power whenever it needs to. Driving with cruise on a motorway trip at 140 kph I can easily get 5.1 L/100kms, or 55 imp mpg or 45.79 us mpg.
By the time I get through town or to my destination that always drops to 4.2-4.5. Something no Diesel I've ever driven of similar size could match.
Most of my commute involves a mixture of speeds from 80 kph to 120 kph.
So far over 165 kms on this tank of petrol I'm averaging 4.2L/100kms
Again, the prius is not a normal car and those figures take a bit of practice, so you can't drive it like a normal car, there is far more driver involvement!
