Nah, that's only 200 Wh / mile (Model 3's 55kWh/215miles range = 255Wh/mile). We could probably do that with weight drops through better batteries, and reduction of safety equipment (no longer needed due to moving cargo to trains, and autonomous driving). Aerodynamics can also be improved through similar methods. Even if all needed to come from drag coefficient, that is only a Cd of 0.16 (from 0.21), which the VW XL1 has now.
