The entire class is a collection of floating, comfort-focused barges. Don’t expect much in terms of handling or driving fun, because if you care about those things you shouldn’t be buying a 16-foot-long sedan.
In terms of achieving that class-hallmark comfort, the Kia does a reasonable job. Body motions are more controlled than many full-sizers, and handling is at least reassuring if not impressive. The car is certainly comfortable, but the ride can get a bit busy at highway speeds as both ends start to move around a bit. Again, par for the class.
Power comes from a 3.3-liter V6, delivering 290 horsepower to the front wheels via an eight-speed automatic. That’s enough so you never really have to dip too far into the gas pedal to get up to speed, contributing to the Cadenza’s relaxed demeanor. Since it makes the best of all eight cogs, you also get up to 28mpg on the highway.
