@CMoZ to this thread since this is 2020 vehicle related, not really Acceleration boost related.
So, I found the definitive proof that the Performance for 2020 has greater range than the AWD 2020. The EPA documents have not yet been published, but the CARB has their Executive Orders which must be issued before sale of the vehicle, which include the drive cycle data for each variant. These are UDDS (Urban/City) cycle numbers; no highway test here, but they can be compared relative to prior data.

If you multiply these numbers by the 2-cycle to 5-cycle ratio of 0.7032, you will find the numbers sometimes match the EPA datafile, but there are some inconsistencies there. But it does not matter, really.
Extra Performance efficiency secured!
A couple of factors here: If you're comparing vehicles with different 100% rated mile values with the same size battery, that means the energy per mile is different. So they will charge at different rates even with equal energy input. (But total energy into the battery per unit time and total charging time will be identical.)
The other thing is the charging efficiency. We don't know yet, but the 2020 vehicles may have slightly improved the on-board charger. This results in a better efficiency metric (more power into the battery for a fixed amount of power from the wall). If you squint really closely at the EPA data, you can make the argument that the efficiency may be a couple % improved over prior years. We don't have the documents yet to say definitively, though. That would make the charging rates slightly different, too.
