For the 2012 model year, the Ford Edge gets a serious fuel economy boost by the way of turbocharging. However, its V-6 versions still have only average gas mileage.
The new EcoBoost option is available on Edge SE and higher trim levels. It features a 2.0-liter turbocharged four-cylinder engine and six-speed automatic for a net of 240 horsepower and 270 pound-feet of torque. Ford says it will earn an EPA highway rating of 21/30 mpg, excellent numbers for the five-passenger crossover market. The engine's not alone in its hard work: direct injection is a big factor in fuel economy, but Ford also uses lower rolling-resistance 18-inch tires to cut down on friction, while it also employs an active aerodynamic grill that closes at lower engine temperatures, improving airflow and reducing drag.
Other models aren't quite as frugal. The front-drive Edge with Ford's 3.5-liter V-6 is rated at 19/27 mpg; adding all-wheel drive drops figures to 18/25 mpg, which is where the 3.7-liter Edge Sport starts out. An AWD Edge Sport has the least efficient drivetrain, at 17/23 mpg.
