In driving like that where there is lots of braking done, a heavier vehicle is ALWAYS going to waste much, much more actual energy than a light vehicle. The heavier hybrid will be able to recover much more energy than the light one, so that is more "free" energy overall to use to get the weight going again, meaning it is more efficient.
Ever notice how a Prius actually gets better gas mileage in the city? If you don't understand why, pls refer to the first two pics I posted.
