For the ecoboost engine in particular 190 200 seems to be the best temperature.
Ford active grille shutters are special shutters in the grill that are opened and closed automatically to reduce aerodynamic drag while still allowing for proper cooling.
These are great for cold weather climates like canada but horrible if its not cold outside.
Essentially a way to boost fuel economy at higher speeds active grill.
But just like george foreman the engineers at ford are always looking for ways to make things better even the lowly grille.
Active grille shutters are a system that optimize aerodynamics by using vents within the grille to adjust airflow to the engine department.
When the shutters are closed aerodynamics are improved by up to 6 resulting in improved fuel economy.
