I have my doubts about this info from Tesla UK. The WLTP ranges were all updated to account for battery changes, e.g. BT43 instead of BT42 in the M3P. The inventory 2022 M3P with 352 miles range has the BT42.These inventory cars with 352 miles have the Intel processor so there is a 12 mile mileage reduction for the Ryzen processor.
It might be that there is a further reduction in range from the Ryzen, as others have been asked to accept versus the published spec.
[Edited] I just grabbed this off the German forum, from V21 certification.
M3P range reduces from 567Km (352m) to 559Km (347m) with Ryzen.
