I’m not for electric cars.
But an electric motor is 90+% efficient.
An ICE is approx. 24% efficient.
Too bad there’s so much other crap to complicate it though.
The batteries are not cutting it.
Now you could put a trailer on the back of your hybrid, carrying a coal powered steam engine running a generator, and a supply of coal.
You'd have to stop once in a while to stoke the fire, and it would belch black smoke, but hey...you'd have unlimited range. And it would at least be honest.
