For 2012, the Ford Edge gets a new, optional turbocharged four-cylinder "EcoBoost" engine that essentially produces the power of a V6 but returns the fuel economy of a four-cylinder. The EcoBoost Edge also comes with aerodynamic enhancements, which include shutters in the grille that automatically open and close based on speed for improved airflow. The Edge is one of the most popular SUVs in the country, and after last year's overhaul, it's easy to see why.
