Edit: I should point out as well that they are actually building EV cars right now. They have a joint venture with several other Japan car manufacturers. They will start selling for the 2020 sales year (which I expect will start pretty soon).
I mean, check the tag line on Toyota's own site: https://www.toyota.com/alternative-fuel/
Hybrid. Plug-in Hybrid (yay?). Fuel Cell EV.
That's their game plan. Even then the only plug-in hybrid is the Prius, none of their other cars seem to be plug-in capable.
