Have the hardware option to provide 72 or 80 amp AC charging when buying new or as a retrofit.
This option used to be available, but was removed in late 2018 from all models and the only option in new vehicles is 48 amps (11.5 kW in USA).
This is needed as some public locations that have higher power AC available. If you have limited time at such a location, the current onboard chargers do not cut it.
A better argument is done by Bjorn here.
