Fyi. I havent test drived the 2022 with 18.8kwh battery yet.Volvo is doing it right now, putting 18.8Kwh battery in same T8 body. We don't know if they had left spare space inside the battery pack or the new cells are higher capacity.
But it seems that space was taken from underneath the middle console. Shallower storage space and removed drive selection wheel. But this is just my speculations atm.
I am really looking forward to the possibility to tune or upgrade the battery for the current models. But for my2019+ someone need to crack the Denso/freescale first..
