One thing that always puzzled me was how the gas engines in hybrids were so efficient. Technology Connections has a great video explainer: <a href="https://www.youtube.com/watch?v=KnUFH5GX_fI" rel="nofollow">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
Yup, my friends had one and loved it despite the... unique styling.
They live in the Puget Sound area, and both work at the same place. It worked out to where they could do their commute, and ordinary errands entirely on battery, and only needed the range extender if they were going into downtown Seattle or on a road trip or such.

the ICE extender was an option.
