I received the downgrade too.
Changes so far were as expected:
1) Less range
2) No fog lights
3) No immersive sound
I haven’t noticed any difference at all
since:
1) I drive using the chill mode to save energy, tires and have various components being less stressed
1b) I drive 12 miles roundtrip as daily commute
2) Luckily we don’t have fog... And I try to limit the use of lights when needed to avoid additional consumption
3) I’m not an audiophile, in the car I mostly listen to podcast about sports or finance so immersive sound doesn’t make a difference to me (not saying it’s not noticeable, I’m saying I don’t need immersive sound)
No changes (so still available)
