Sorry no on the ‘how are they supporting 400V?’ point. Really that’s just a deduction.Oooh. Very interesting. Do you have a link please?
If it were reusing the AC charger it would be much lower power, and if it were reconfiguring the pack they’d surely just be offering 150kW out of the box.
The other info is in the car spec/pricing/options configurator which is now online.
