The 2013 Lincoln MKS is a big luxury sedan, and despite the introduction of a few more fuel-saving technologies this year it doesn't offer gas mileage that's any better than the norm for a vehicle this size.
Active Grille Shutters, now included in 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.
Base versions of the MKS earn EPA ratings of 18/27 mpg--2 mpg better on the highway than last year. That's still quite low figure for a modern V-6-powered sedan. EcoBoost turbo versions with all-wheel drive are rated 17/25, while AWD 3.7-liter versions get 18/26 mpg.
