The EPA posted fuel economy numbers for the 2013 Ford Fusion in front-wheel-drive, all-wheel-drive and hybrid flavors, but they were quickly removed from certain parts of the FuelEconomy.gov website. Car and Driver snagged the numbers before they disappeared, however, and it makes for fine reading.
It's a toss-up nowadays as to whether an automatic or manual will get the ultimate economy, but the best numbers among the conventional Fusion powertrains are the 25 city / 37 highway miles per gallon returned by the six-speed-manual-equipped FWD Fusion with the 179-horsepower 1.6-liter EcoBoost motor. Numbers for the six-speed automatic are right behind, at 23 city / 36 highway.
Dropping nine horsepower and a turbocharger will get you price but not efficiency gains, with the 170-hp naturally-aspirated 2.5-liter four doing 22 city / 34 hwy. In the other direction, that's one small mpg away from the 22 hwy / 33 city to be had by the 237-hp 2.0-liter turbo four-cylinder. Add all-wheel drive to the equation and pay a 2-mpg penalty, with the 237-hp motor doing 22 city / 31 hwy when turning all four wheels.
Of course the hybrid Fusion killed it, getting 47 city and 47 hwy. That is only bested by the 2012 Toyota Prius C and Prius, ties the 2013 Ford C-Max Hybrid and beats the 2012 Honda Civic Hybrid. Among its competitors, the Fusion is in the mosh pit with the 2012 Toyota Camry's 25 city / 35 hwy, the Honda Accord's 27 city / 37 hwy and the Chevrolet Malibu's 22 city / 34 hwy, with just the sedan-surfing Nissan Altima jumping out at 27 city / 38 hwy.
