Engine temperatures
I've got two OM606s, one in the E-class and one in the G-class. Both run at just under 80C in normal traffic. The E's temperature gauge hardly ever varies. The G weighs twice as much when loaded for travel and has the aerodynamics of a postal truck. Climbing long steep hills in the heat gets the temp up to 87C. The only time I've seen 100C is when the fan failed.
