M3's came out of giga Shanghai since early Jan 2022 have the following updates:
- Ryzen chip (replaced intel atom chip)
- compact & long lasting 12v Li-ion battery (replaced 12v lead-acid battery - 12kg+)
- windscreen wipers heaters
- new redesign LED tail light cluster (dual reversing lights, larger brake/turning lights)
- Darker roof glass tint
Above updates had confirmed by SA's since early Jan, and also AU owners in this group started taking 2022 deliveries from early-mid Feb. If you had ordered your M3 on 29/01, further delay to your delivery date is unlikely to add any extras to the final car, giving the upward pressure on pricing & global chip shortage.
Having said that, the following features were rumoured to be added to 2022 M3's since late last year:
- Ventilated front seats
- Double-pane rear window glass
