So, the Item in Panorama was in the tech section, relating to the engine oil in a GT4 and asking if A40 oil could be used or if only C40 (the spec required to protect GPFs) is OK. The response was as stated, all MY 21+ need C40, since they have the gas particulate filter system. Maybe they changed their minds, but that is what the mag says . . .
Read that as well although the source was not identified. . Unsure if the 2021 C2S picked up yesterday has them or not, but this is where to look for them:
My 2021 does NOT have a GPF. It is just a CAT and is the same size as the Soul cat I installed. There is no GPF inside. Here is what it looks like from the Turbo end.
Immediately following the catalysts in the flow of the exhaust gases. It's probably useful to think of an Exhaust Particulate Filter as an Air Filter in the exhaust stream that attempts to cause the air leaving the engine to be as particulate free as the air entering the engine after passing through the Intake Air Filter.
GPF costs more than just a cat. Porsche won't spend the money unless it is required by the EPA/CARB. Check the EPA/CARB rules and that will tell you when we get GPF. Porsche won't just do it without a good reason.
