Based on the Ford Fusion, the upscale MKZ has a luxurious, quiet interior, and its ride and handling rival some high-end European sports sedans. Powertrains include a 2.0-liter turbocharged four-cylinder and a 3.7-liter V6, each matched with a six-speed automatic. There's also a hybrid, which returned a near-class-best 34 mpg overall in our tests. The push-button gear selector and touch-sensitive controls for climate and audio functions are frustrating to use. And the modern styling compromises cabin access and rear-seat room. Reliability has been average. An updated 2017 MKZ with more powerful engines, a revised infotainment system, and simpler controls goes on sale this summer.
