I know this is an old thread, but a new study just came out [1]. 300% overestimated utility factor. It underscores my point that the category of PHEVs is largely a scam to cheat emissions regs.

However! It somewhat undermines my argument about the rav4, as it seems Toyotas are indeed the most charged / highest UF phevs.

Still drastically overestimated, just the least bad.
