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?
