I enjoy that guy, but I've found he is wrong about what he talks about in several situations. This is probably one of them, but we'll see once the EREVs are tested. His argument here is basically, "The Volt wasn't fuel efficient so EREVs can't be". Ignoring all the has been learned about EVs since then. Plus he ignores that PHEVs and Hybrids are more complex than an EREV because they need complex transmissions and other subsystems because they need to be both an EV and an ICE vehicle.
I have an EV and a hybrid, and the EV is so much better than the hybrid - I will happily swap the hybrid for an EREV when the time comes.
