Agree with C Swenson. Mine (2015 S550), once warmed up in a few minutes, is always at 190 or 200F. Like clockwork.

I am going to chime in....hmmmm..yes. Normal
I dont think the temp really is 190 or 200. Its probably 195, 196. I say that because it can change from 190 to 200 pretty quickly and then again back down to 190

I have also noticed that M278 engines slightly runs higher than 6 cylinders like M276
