But if you're looking for best fuel economy, you need to scrap both diesel and gas IC engines eventually, and go to a Stirling-engined PHEV system. The electric system provides primary drive, and the starting torque & immediate startup that Stirlings don't have, while the Stirling engine turns fuel into power in the most thermodynamically-efficient way possible for a heat engine.

Though of course the ultimate would be a fuel cell that runs on biofuel of some sort. I seem to remember an alcohol-fueled one, and don't offhand see why it shouldn't be possible to run one on sugar.

And in fact it seems to be possible:
