    560 EPA mile range maths out to 446 Wh/mile, not unreasonable for improved efficiency under favorable conditions.
    Also implies 535 Wh/mile for a 300kWh pack, fair numbers if we consider each motor may get its own 100kWh pack (simplifying manufacture of single/dual/tri motor configurations).

    Even with battery cost improvements, a 250kWh battery isn't economical. You'd still be looking at the battery alone costing >$20k and weighing around 1000kg. It would take more than 30 hours to charge on a typical 50A 240V home circuit. A 250kW battery is borderline impractical.

    With good gains in powertrain efficiency and aerodynamics, the Cybertruck should get down to around 400wh/mi, giving a 500mi range with a much more reasonable 200kWh pack. With the HPWC, you could get that thing charged in around 16 hours, around the upper limit of practicality.

    I'm pretty sure that's 72A peak, which is around 50A RMS. AC power = voltage * RMS current, which would be 12kW, not 17kW

    (I could be wrong though)
