I think the term of art in the automotive space so far has been "series hybrid". But like you said, the differentiation here may just be the size of the battery. Series hybrids are still predominantly driven by fossil fuels, even if the drive is an EV drivetrain, due to the battery mainly acting as an energy buffer.
The absolute sweet spot, as someone from a country with long long distances, is a plugin series hybrid that has ~150-300km EV range and a ~60 litre fuel tank. That's getting me to work entirely electric, and then once a month when I need to see family I can chew down the fossil fuels.
Yeah, the difference is the Powerboost hybrid electric motor is only like 50 hp. I want 350 hp of electric motor that can be powered by either the battery or an onboard ICE.
