I'm assuming JB is referring to hardware and that much of it will be non-apparent. Possibilities/opportunities: Structural: Advances in Lightweighting? Greater ease of assembly? Even better crash-worthiness? (NCAP 7??) Powertrain: More efficient motor rotor cooling? Improved motor torque-rpm profile? Battery: Improved battery performance in cold weather? Faster Supercharging? Any other possible hardware improvements?
