We can do some math on that. Trucks, especially heavy-duty ones that can tow that much, are big and heavy and tend to have poor aerodynamics. I'll be generous and suggest they might be able to manage 500 Wh / mile, or two miles per kWh, though it'll almost certainly be worse. And that's obviously for just the truck, unloaded. So, to target a 200 mile range for the unloaded truck, you'd need at least a 100 kWh (usable) battery. That's more battery than Tesla has ever sold in a vehicle. Now, load the truck down with 4,000 pounds in a decidedly-not-aerodynamic horse trailer and push the range to 250 miles? I think it'd still be generous to merely double the battery requirement. And you're now looking at the same class of problem that rocket scientists face...a quarter of a megawatt-hour of battery capacity is itself going to be insanely heavy, requiring even _more_ battery to make up for all the extra battery you're hauling. And all this is supposed to cost $15K _less_ than a base-model Tesla Model S? I don't think so! b& -------------- next part -------------- A non-text attachment was scrubbed...
