Nissan's third generation e-POWER powertrain

One thing that always puzzled me was how the gas engines in hybrids were so efficient. Technology Connections has a great video explainer: https://www.youtube.com/watch?v=KnUFH5GX_fI

tl;dw: constant RPM and a weird stroke geometry where the power stroke is longer than the other strokes to extract more energy from the expanding gasses.

I'm surprised there isn't more effort to create hybrids in reverse--an electric car with optional gas generator. The gas generator could run at constant speed, never changing RMP, while the battery handles constant changes in acceleration. The idea is not mine. I've heard about it in China

Hopefully it’s better than the second gen. Gas engine front only puts power to one wheel and electric rear only puts power to one wheel while the other two sit idle. Bad state for a mild 4x4 unless you keep it on pavement.
