For each of those 51 hybrids you need to manufacture an extra ICE engine. Which is not cheap. It's more complex to make a drive train that can seamlessly handle switching from EV to ICE. So it's more difficult to manufacture. Has there been a study that takes the whole lifecycle of a hybrid into account vs an EV or ICE?
Would be super interested if there had been a research that also takes into account that we don't need SUVs that seems to be the go to car in the US.
ICE engines may be more complex, but batteries are still more expensive than a small ICE engine. Have you seen the cost of a replacement battery for a Tesla? $12-20k all day long. You don't need a massive, high performance ICE engine to charge up batteries on the go, or to get your car down the highway. Meanwhile I can get a high performance crate engine for less than half that cost ($5-6k all day). Less than half that for a basic, economical 4 banger.
