Case Study Flex R&D Leads to Smart Airflow Controls The pressure to create more fuel-efficient vehicles is mounting thanks to a mixture of government regulations and environmentally conscious consumers. One automaker wanted to improve its fuel efficiency by exploring an emerging trend in vehicle design—active grille shutters. These are shutters that are integrated into the vehicle’s front intake grille to alter the flow of air to the engine, promoting cooling when open and fuel-sparing aerodynamics when closed. Active grille shutters are a relatively new technique in automotive design, and they carry some challenges, particularly in safety and durability. For example, the vendor must be confident that a grille won’t get stuck in ways that would affect vehicle performance o
