"Forty miles...and it is 55 miles north, or 55 miles south to the nearest "market town" that has any big stores. Nope; I'll pass."
If you could "recharge" at your destination, your one hundred and ten mile journey would cost you a gallon of gas.
Forty miles on electricity (battery)
Fifteen miles on gas (generator)
Recharge while shopping
Forty miles on electricity again
Fifteen miles on gas to home
So even in an extreme case, it could be of benefit.
Rule number one when driving a hybrid: Only pick up hitchhikers at the tops of hill, and drop them off at the bottoms.
For shame!!
Waste all that momentum? Accelerate UP the other side? ONLY stop at hill tops.
It has been too many decades since I took any physics, but just how many KWH worth of motors are we talking about? How many HP & KWH on the IC/generator setup? Just how efficient is their super-expensive IC?
What about (as it will be by the end of the week) below zero temps drastically reducing the battery's efficiency?
Which brings us to creature comforts: climate control; 200+W stereo systems, heated leather seats?
Then we hit the foul weather & night driving drains: HEADLIGHTS, wipers, electric defrosters, etc?
It was hard to tell from the picture, but just what kind of seating, payload, cargo cubage, & towing capacity at highway speeds, assuming several miles of 4-6% grades, are they designing in?
For the flat-lander commuter, with rare to occasional longer trips to Grandma's or the beach, maybe; but when they mentioned their "600 miles without stopping" they left out a heck of a lot of caveats. Oh, for that trip, better add in an electronic cooler for the snacks & sodas, too.
