At what speed range is active grille shutter generally closed?
Active grille shutters are an innovative feature in modern vehicles designed to enhance aerodynamics and improve fuel efficiency. As the owner of Kevin's Autos, I want to share insights into how these components function, particularly focusing on the speed range at which they typically close.
What Are Active Grille Shutters?
Active grille shutters are adjustable panels located in the front grille of a vehicle. Their primary purpose is to control airflow into the engine compartment. By opening and closing based on driving conditions, these shutters help optimize engine temperature and reduce drag, ultimately contributing to better fuel economy.
Speed Range for Closure
Generally, active grille shutters are designed to close at higher speeds, typically around 30 to 50 miles per hour (48 to 80 kilometers per hour). This speed range allows the vehicle to minimize aerodynamic drag while maintaining optimal engine performance. When the vehicle is traveling at these speeds, the shutters close to streamline airflow, which can lead to improved fuel efficiency.
Benefits of Active Grille Shutters
Here are some key benefits of having active grille shutters in your vehicle:
- Improved Fuel Efficiency: By reducing drag, active grille shutters can enhance fuel economy, especially during highway driving.
- Optimal Engine Temperature: These shutters help maintain the engine at the right temperature by controlling airflow, which is crucial for performance and longevity.
- Reduced Emissions: Better fuel efficiency translates to lower emissions, making your vehicle more environmentally friendly.
Conclusion
Understanding the operation of active grille shutters can help you appreciate the engineering behind modern vehicles. By closing at speeds between 30 to 50 mph, these components play a vital role in enhancing performance and efficiency.

Frequently Asked Questions
Are active grill shutters necessary?
Whilst the primary function of the active grille shutters is to reduce the aerodynamic drag of the car, there are some secondary benefits like improving the warm up time of engine and also retaining engine heat when parked.
Why is my active grille air shutter a performance stuck off?
In some cases, it may be due to a faulty active grille air shutter actuator, while in others, it might be because of debris obstructing or impeding one of the active grille air shutters. It's common for these shutters to be affected by front end impacts to the vehicle, including impacts from debris and hazards.
At what speed range is the 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), engine coolant temperature (approximately less than 203°F), engine oil temperature (approximately less than 284°F), CVT fluid temperature (approximately 275°F), ...
Should a grill shutter be open or closed?
Yes, you can drive with the shutters open. It is a failsafe design so that they won't block airflow through the radiator and cause the engine to overheat.
What is the active grill shutter?
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%.
When should you close the grill?
You want to grill with the lid down when you're using indirect heat on items like bone-in chicken breasts, or slow-cooking something huge like a brisket that needs long exposure to low heat so it can reach doneness without a completely charred exterior.
What is the benefit of the active grille shutter on 2025 Rogue?
Enhancing Efficiency: The Benefits of the Active Grille Shutter on the 2025 Nissan Rogue. The 2025 Nissan Rogue boasts several advancements aimed at improving fuel economy and overall performance.
What is the code for active grille shutters?
P059F
Common indicators that an active grill shutter could be involved with your check engine light are: Error Codes: Error codes such as P05A0 or P059F indicate active grill shutter malfunction. They signal to the ECU that there has been an issue with its operation, typically the active shutter not moving smoothly enough.
What is the closing speed of a fire shutter?
g) Average closing speed: No less than 6” per second or more than 9” per second. h) Resetting of spring tension or mechanical dropouts shall not be required.
What is the performance of the active grille air shutter?
The advantages of Active Grille Shutter at a glance:
Closed air flaps smooth out the vehicle front and reduce the drag coefficient. In addition, the engine reaches operating temperature more quickly and remains hot for longer after it is has been switched off.
