From an, "I need range" perspective, I suspect the closest I'll ever get in the future to an electric vehicle is some sort of Hybrid drive vehicle with an on-board generator in which your range is only limited by the generator's fuel tank, just like now when you're driving a Hybrid or internal combustion vehicle.
Various manufacturers have been planning the truck equivalent of a diesel-electric hybrid for a while, though I have not seen one hit the market.
The engineering to get that working in a passenger truck must more difficult than it seems, but the range from a diesel engine that can run in its most fuel efficient band all the time, with the upsides of full-torque-at-any-speed electric motors driving each wheel independently, plus losing all the traditional drivetrain components, seems pretty sweet.
