What are RAM active grille shutters?

[heavybutterfly196]

The new 2013 Ram 1500 is the first pickup truck to employ an active grille shutter system, which automatically closes the huge grille when cooling is least needed. The system improves fuel economy by 0.5 percent by reducing drag roughly 3 to 5 percent and improves warm-up time and windshield-defrost time.

Located between the front grille and the condenser, the Active Grille Shutters (AGS), otherwise known as Radiator Shutter Assembly, are plastic shutters that open or close to control the airflow going under the hood.

Subsequently, question is, what is the purpose of active grill shutters? Active grille shutters are popping up on a number of new models, including the 2015 Ford Mustang. The shutters open and close automatically to control airflow, reducing aerodynamic drag and improving fuel efficiency.

what is active grille shutters?

Active Grille shutters are designed for extreme air-flow conditions (10 % of driving conditions): the active grille shutter system opens the radiator air inlet at the front of the vehicle when the air conditioning is at the highest setting and helps improve the aerodynamic drag coefficient by an average of 9%.

At what speed range is active grille shutter generally closed?

The ECM operates the shutter to the closed position when all the conditions of the active grille shutter are met: Vehicle speed – approximately 19-88 MPH (30 - 140 km/h) Engine coolant temperature – less than 203°F (95°C)
