I should add, I dont know about what the cost would be, for a let's say, 75hp (so we don't need the horse pee) Kubota diesel generator engine, 2-4 electric drive motors, and say, 2 hours worth of battery power stored on board. I would imagine weight could be reduced by using 1/4-1/2 the battery capacity of a 100% EV, but we gain weight with the ICE. Let's make it electric, air cooled, so we reduce some of the additional weight, but we still need to carry diesel fuel. Now, we run our 4000 lbs, 5 passenger, mid sized car, on 2 hours worth of battery life, a 75hp air cooled diesel, and maybe 8-13 gal of fuel. Maybe when going cross country, we get a "limp" mod, where our 75hp Kub engine isn't generating enough "juice" to run our AC, and keep the car at 85mph, and we get a warning light, and reduce speed to 45mph, and turn the accessories off, while we get off at the next exit for a 5 min pee and power up?
I accept I don't know what the cost of 2 or 4 electric drive motors are, or the weight, I dont know the cost or weight of our battery pack, but theoretically, we have a system that would be Very cheap to Run, purchase price might be out the window? We also use less rare earth minerals (no idea if that is truly a major issue, or a buzz word of the minute); we probably save some fuel, and we could also have a reverse feed power system, where your car can plug into the home charging station, and supply back up power to the home, off our diesel generator.
I also admit, I dont know how the partial recharging and constant charging of the battery off the generator engine would affect battery heat/life/chemistry.
