Magna launches fuel-saving grille technology

The system reduces drag while maintaining optimal engine temperatures.



AURORA, Ont.—Magna International Inc.’s Magna Exteriors and Interiors (MEI) operating unit has developed an Active Grille Shutter (AGS), a louver system that blocks front-end airflow openings on vehicles, reducing drag while maintaining optimal engine temperatures.

Reduced drag is a key factor for improving vehicle fuel efficiency.

The system’s louvers, functioning like household blinds, automatically open and close based on various inputs from the vehicle.

When a vehicle is traveling at highway speeds the louvers remain closed, which directs airflow around the vehicle to reduce drag. In situations such as sitting in hot traffic, traveling uphill or pulling a trailer, the shutters remain open and send into the engine compartment for optimal cooling.

“Nearly every passenger vehicle introduced in upcoming years will have some kind of active shutter system,” said Bob Brownlee, President of Magna Exteriors and Interiors.

Magna’s AGS made its debut on the 2013 Dodge Dart and Ram 1500 pickup truck, with more vehicles expected to follow.

Similar systems can be found in the Ford Focus and the Chevrolet Cruze Eco.
