Ford's adding a new engine to its Fusion lineup in the hopes of increasing fuel economy. Turns out, the turbocharged 1.5-liter EcoBoost four-cylinder is slightly less efficient than the current 1.6-liter EcoBoost.
The 178-horsepower 1.5-liter, which is optional on SE models, is rated at 23/36/28 mpg city/highway/combined with the six-speed automatic transmission, according to the EPA. For 2014, the 178-hp 1.6-liter can only be equipped with a manual transmission and is rated slightly higher at 25/37/29 mpg.
Like the 1.6-liter, the new 1.5-liter will be available with stop-start engine technology. A 2.5-liter four-cylinder (22/34/26 mpg) remains standard on the S and SE models, and the Titanium retains a standard turbocharged 2.0-liter four-cylinder that makes 22/33/26 mpg (front-wheel-drive versions.)
