Sorry, to be more exact I should have said efficiency.
I was taking into account energy lost due to conversion at the engine where an ICE is between 20 and 25% efficient, or wheel to wheel efficiency if you will, I thought that would have been self-explanatory.
Even accounting for that pretty sure it’s still wrong, that’s why ICE vehicles usually have better range despite not stuffing gas tanks into every available space.
You know what that’s fair, I was speaking in a informal tense for which I should have avoided using technical terms to dissuade ambiguity
Imo it was clear what you mean if you apply any benefit of the doubt. But we’re on reddit, so they didn’t. (I know it’s not reddit, das de joke.)
It’s correct though.
ICE efficiency in a car ~ 20% for a car, gas to wheels.
Worst case scenario :
Electric cycle efficiency : ~33%
You need to add ~15% overweight for EV, making a conservative 28% total cycle efficiency.
It is definitely the energy density which makes the difference.
