I wonder if they designed the vehicle based on hybrid model so non hybrid model has more spare space under the hood, body, etc…so people did not see the gain in possible space with non hybrid models….or the battery and electric motor really take up very little space.  I think the batteries are wider and flatter so more easily hidden.   regardless, good to hear you are happy with yours.  Do you ever compare with your neighbors the differences in fuel savings?

0, you'd never know the difference between mine and a non hybrid - they're identical on the inside and outside My neighbor has the exact same vehicle - non hybrid model - can't tell

What space is lost in the vehicle with both a battery, gasoline engine and I assume electric motor that must attach to the vehicle drive train?

That is what I have. I will admit it works VERY well - and IMO - is the absolute perfect/best of both worlds and nothing more than that is needed to save all of us from melting, or freezing, whichever the climate changers tell us will happen

I could see the benefit to a hybrid vehicle.   Honda makes one.  Not a plug in hybrid, but the battery is charged by the gas engine, and engine shuts off and on as needed.  IIRC.   I would never own a fully electric vehicle.  Living in the country, everything is 20 minutes away ( except the snowmobile trail, I can see this from my house👍)
