Although the styling changes are subtle, the redesigned 2017 Cadenza features an all-new body structure. The new car is based on the Kia Optima, but it is considerably larger, competing with the Toyota Avalon and Chevrolet Impala. The car is roomy and quiet, with easy-to-use controls. Ride and handling are nothing special but pleasant enough. The 290-hp, 3.3-liter V6 is slick and powerful, and the eight-speed automatic shifts smoothly. Higher-end Limited versions include more soft-touch surfaces, real stitching on the dashboard, and available Nappa leather seats. Automatic emergency braking, adaptive cruise control, and lane-departure warning are available.
