Coolant temperature stabilizes at 78°C and it's hard to get it over 82°C without blocking the upper grille. If I block it (winter) the temperature will go up to 88-90°C, but often falls back to ~80°C when hypermiling. I believe that the engine "likes" to be closer to 90°C, consumption may be a tad bit lower then.

The upper grille is blocked November thru April. Both sides of the lower grille are closed when I start the car and I open the intercooler side when the coolant warms up to ~70°C. I open the radiator side only when the coolant temp stays above 90°C, to keep the fan from cycling on too often (turns on @ 97°C, off @ 89°C).
