Ok, so I did a long drive yesterday, used my OBD2 connector and compared it with the temp gauge. Below is the results I saw....
179F - Below the middle line, halfway between the middle and next lower hatch mark
190F - Just under middle line
195F - Exactly in the middle line
200F - Just over the middle line
205F - A few mm above the middle line (what most of us see when we drive)
207F - The highest temp I saw all day, including sitting for a while in a drive thru line.
In short, this car is by far the coolest running vehicle I have. Yes, modern cars are designed to run hotter these days, but still impressive that my Crossfire’s hottest temp is at the same level at the coolest operational temp of our newer RAM & Toyota vehicles. Don’t let the gauge needle location worry you, your car is likely running very cool.

Example of operational range:
2004 Crossfire 179F – 207F
2019 RAM Rebel 205F – 228F
