Ok, so now that we're talking about a External Combustion Engine Hybrid... with turbo...
So, how do you hypermile in one of those? ... Because we can't NICE-On Coast, since there is no need for 'N', and no ICE. There is no 5th gear. There's just a pedal to deliver your fuel/air-mixture directly to the giant blowtorch in back. Pulse-and-Glide? Honestly, that would be kinda like ambling down the road while periodically burning your farts. Which intuitively would seem more energy-efficient than burning one long fart continuously and very slowly... as you would be forced to do going up hill. But I suppose that's where the "Hybrid" part clicks in, since that would be kind of like the aerosol-can-fart-rocket-assist, again very annoying to non-hypermilers, who unfortunately would find it difficult to read your "No, I'm not old, I'm hypermiling" bumper sticker due to the glare. On the other hand, most may find it impressive enough to forgive your cardboard wheel skirts.
