The document details how Flex and its Mirror Controls International subsidiary supported a leading automaker in developing active grille shutters. Using Sketch-to-Scale design and Smart Control actuators with fail-safe defaults, the solution reduced aerodynamic drag while ensuring engine cooling and regulatory compliance. The approach simplified the system architecture and lowered component count.

Key takeaways

Active grille shutters reduce drag and improve fuel efficiency when closed

Smart Control uses centralized intelligence to manage multiple actuators without separate PCBs

Fail-safe design defaults shutters open on power or signal loss to prevent engine overheating

Integration at the design stage reduces part count and improves reliability

Lower cabin noise achieved through controlled air intake
