Oddbean new post about login | logout Maybe manufacturers are afraid of the "sticker shock" of diesel vs unleaded at the pump.
In Europe diesels are everywhere, a lot of them get like 50-70 mpg on the highway, you add in regenerative breaking and you should be able to get 40-50 even in stop-and-go city driving. But diesel engines are a bit more costly than gasoline engines, so it might be that nobody wants to combine diesel cost with battery cost...
