What is the scientific explantion of how a hybrid vehicle achieve

So where does the additional fuel efficiency stem from? Do hybrid
vechicles employ regernative braking which partially charges their
batteries at every braked stop?
The designs I have had a look at don't, so where is this increased
fuel efficiency coming from, or is this simply an empty marketing
gimmick based on drivers doing a greater abount of coasting?
What designs have you seen that don't use regenerative braking? I
haven't looked at all of them. But I do know the Prius certainly does.
To know, all you have to do is look at city/highway mileage. Those with
a much higher city will use regenerative braking.
Another fuel saver is their smaller size and smaller bhp.
