Go to Toyota's website today and you'll see that a Rav4 Plug-in Hybrid is more expensive than the bZ which is the equivalent full EV.
Going to an EREV layout (a series plug-in hybrid where the gas engine cannot drive the wheels mechanically) doesn't really save any costs directly, but allows sharing the platform between EV and EREV models.
An EREV is basically the worst of almost all worlds. It's a BEV with a motor tacked on. It ends up with a battery not a lot smaller than a pure BEV, so no real reduction in the cost of an expensive component, plus an engine and generator along with associated maintenance headaches. Not to mention the almost certain loss of cargo capacity.
I can't see myself ever wanting a Lightning EREV, for example, because of this exact issue. If I needed to tow, that would be the sole situation where it might hold enough of an advantage to matter. Aside from that, it will have (most likely) about 75% of the battery the BEV Lightning has, and it will lose the frunk, which is one of my favorite features. Plus, unlike my Lightning with it's 200K mile first required maintenance work, the EREV will probably have to be serviced every 10-20K miles. Ugh.
