There axtually is at least one diesel/electric hybrid car but not in the US. I’ve had it explained to me that diesel is costly, hybrid electric is coatly and so the combination of the two is economically unfeasible as far as the market. While the cost issue is true, there is atleast one as I mentioned. We get short shrift on diesel passenger vehicles and small trucks. Why, I’m not certain but some have said it pertains to refinery infrastructure limiting the amount of diesel fuel that can be made available.
There are several diesel-electric hybrid cars on the market, in the EU. The one that is regarded as the best at present is a Citroen, bless their weird little hearts. Should’ve known, lol. I hate that they’re no longer sold in the US. Very innovative, not at all afraid to be different and they’re good at it. The worst ones are also French though. Peugeot. Pieces of crap from what I read. Par for the course there, too, lol.
