I would like to see a gas/steam hybrid engine that uses waste heat from the engine to make steam to power an additional couple of pistons. That might get you better gas mileage than a gas/electric hybrid.

The best setup for that is not additional cylinders, but to run a 6-stroke cycle - injecting a drop of water at the end of the exhaust stroke, which will expand and generate some extra power.

Though not terribly efficient, we could certainly use thermoelectric generators like Peltier junctions to pull energy out of the waste heat in car exhaust. On the plus side they are cheap and have no moving parts (and they're not even radioactive).
