The hybrid already gets 55mpg and the batteries are dirt cheap.
Its actually cheaper (for me in the UK) to run a corolla hybrid than an EV as I don't have the ability to charge at home.
Corolla is sort of highly underrated engineering marvel.
Not sure how you got one that gets 55mpg, mine gets 44 (47 was on the sticker). But in CA this still beats 100% EV.
55mpg is nothing. I get 100+ mpg equivalent on my massive F-150 lightning and if you include cost in the comparison it’s probably a couple of multipliers more than that.
Our 2026 hybrid gets 64mpg in Albuquerque. The last time I did the EROI calculation it beat everything by a long shot.
