This three-row SUV is based on the Ford Flex, with a similarly roomy interior and a more stylized shape. Base models are equipped with a lackluster 3.7-liter V6. We tested the uplevel 3.5-liter turbo V6 version, which was quick and returned 18 mpg overall. The ride is comfortable but stiffer than that of the Flex, and the MKT is cumbersome at its cornering limits. The interior is very roomy, plush, and quiet. But visibility and the driving position are compromised, and the third-row seats are best suited for kids. A wide turning circle and overall length hamper maneuverability. Sync 3 has replaced the much-maligned MyLincoln Touch infotainment system.
