GLC 43 and 63 engine future

Just read that MB will be upgrading the C43 and C63 from a 4 cyclinder engine to a 6 cyclinder engine. If that is the future for the C class, are there any plans to do the same for the GLC? Why are they making the change for the C class? I have read that customers want bigger ICE (more cylinders) than souped up 4 with electric motors. Also read that there will only be one model the C53. So the question is does this strategy makes sense for the GLC as well? The Porsche Macaan S has a V6. And Porsche is doubling down on all electric so who knows what the future holds.

They might, the 43 moniker is no more if true. https://mbworld.org/forums/c63-c43-a...g-c43-c63.html

I don't see why the GLC 43 won't become GLC 53 either but given the X254 (2023) is one year newer model year wise for the generation than the W206 (2022) it might take another year after the W206.
