I was just browsing around on the Internet and found some interesting articles on Active Grille Shutters. This technology is used by Ford in the C-Max and Fusion line-ups, and by other manufacturers to improve aerodynamics and hence, overall MPG. I just wonder in the event of failure, what would the cost of repairs be? Perhaps it's time for me to reconsider that Ford-backed extended warranty/service plan...it may be worth it due to all the high-tech that are in the C-Max!?!?! Anyway, I hope you all find it interesting and educational as I have. http://www.greencarreports.com/news/1079678_active-shutter-grille-vents-how-they-help-improve-mpg http://www.tundraheadquarters.com/blog/2012/10/03/how-active-grille-shutters-work/ http://www.sonceboz.com/en/latest-news/latest-news3.html
