The Fusion S and SE come standard with a 2.5-liter four-cylinder engine that's rated at 175 hp and 175 lb-ft of torque. Power is sent to the front wheels through a six-speed automatic transmission. EPA-estimated fuel economy stands at 25 mpg combined (21 city/32 highway), which is average for this class.

For the SE, there are two additional engine options. The first is a turbocharged 1.5-liter four-cylinder that produces 181 hp and 185 lb-ft of torque. It's paired with a six-speed automatic and includes paddle shifters and automatic engine stop-start to help save fuel at stoplights. Fuel economy stands at 27 mpg combined (23 city/34 highway).

Also available on the SE (and standard on the Titanium and Platinum) is the turbocharged 2.0-liter four-cylinder with 240 hp and 270 lb-ft of torque. Front-wheel drive and a six-speed automatic is standard, and all-wheel drive is optional. Front-wheel-drive versions earn 25 mpg combined (21 city/31 highway), while AWD brings the rating down slightly to 23 mpg combined (20 city/29 highway). In Edmunds performance testing, a Fusion Titanium with this engine and AWD accelerated from zero to 60 mph in 6.9 seconds, a little slower than average for a midsize sedan with an upgraded engine.

Unique to the V6 Sport is a turbocharged 2.7-liter V6 engine that develops 325 hp and a whopping 380 lb-ft of torque. All-wheel drive and the six-speed transmission are standard. Expect 20 mpg combined, assuming you drive with restraint.
