What Are the Pros and Cons of Active Grille Shutters?

[AylaMarie]

"Active grille shutters are generally more beneficial than detrimental. Similar to common window shutters, active grille shutters can automatically adjust their opening degree based on actual conditions. The ability to control the opening and closing of the grille means regulating air intake and cooling. For example, during cold winter starts, the grille remains closed, allowing the engine temperature to rise faster, which improves vehicle performance in winter. When the engine temperature is high, the front grille automatically opens for cooling. This means active grille shutters resolve the conflict between summer cooling and winter insulation. Overall, the advantages of active grille shutters outweigh the disadvantages. The primary benefit is the automatic regulation of engine temperature, ensuring the engine always operates at optimal conditions. Additionally, during high-speed driving, closing the grille reduces air resistance, enhancing fuel efficiency. The downside is their higher cost, currently only available in premium models, making this feature absent in mid-to-low-end vehicles."
