The fuel economy for the 2014 Lincoln MKS is average to middling for the segment, ranging from 20 to 22 mpg combined--despite some new fuel-saving technologies added to the big luxury sedan.
The most efficient model is the base front-wheel-drive sedan, which comes with a 3.7-liter V-6 and is rated at 22 mpg combined (19 mpg city, 28 mpg highway). Add all-wheel drive to that model and the ratings fall slightly, to 21 mpg combined (18 mpg city, 26 mpg highway). Finally, the performance option pairs a more powerful turbocharged 3.5-liter EcoBoost V-6 with all-wheel drive; it's rated at 20 mpg combined (17 mpg city, 25 mpg highway).
Active grille shutters--now standard on the 3.7-liter versions of the MKS--smartly open only when more cooling is needed, reducing aerodynamic drag and improving fuel economy on the highway. Also new for the MKS is a smart battery management system that puts a higher priority on battery charging when coasting or decelerating.
