This is not how the fuel consumption guage worked on any of the cars I

Hi Mord,
You are looking for something like this:community:

But you are right that hybrid cars have a lot of user-visible algorithms in
them, and I think this makes it interesting to reverse-engineer.

a few observations:
- forget about honda insight. it is not very fuel-efficient.
- the Prius can give you about the same gasoline consumption as a small
manual car (such as the alto, the i10, etc.). this is true both in-town
and out-of-town.
- one of the reasons that the Prius is much more
