I still can't believe a diesel-electric, "train-locomotive-on-tires" hybrid concept has never been attempted stateside.
Electrical motor torque (from rest) screams to be marketed to American truck buyers. It's the one EV market that probably didn't ever need environmentalism as a boost to be successful.
A 2016 Prius gets ~40++ mpg on a 10 gal tank all day at 90mph. That is, >> 400 mile range per fueling stop. I heard this on the internets, of course, I wouldn't know, personally ;-). Fueling stops imply human fuel as well.
I gazed with amazement at all the fanboyz in the threads above about what a gamechanger this E-truck is. Oh. 230 mile range OPTIMAL. Some hope of a range extending $$$ option.
wrt to your comment, of course that would be a game changer, if a hybrid E-truck could get 40+ mpg with a 400+ mile range. (No comment on the aerodynamics and efficiency at speed) And the imagination goes... yeah, you could now financialize on-site construction generators... emergency power generators... whoa baby let me in where do I invest. Because you could market this to sportsball enthusiasts and then scale. In the US, maybe?
Well, I in fact own a 2001 Tundra V8 4WD which I recently refurbed $3K into because it just works. But I sure wish it got 40 mpg instead of an optimistic 13 mpg. Extra gas tanks are a well known technology for extended off road excursions, for a century now.
I fully expect that to be something the local u-haul rents out for cross-country road-trips.
