The base Premium trim is loaded with features, including 18-inch wheels, foglights, heated mirrors, hands-free trunk opening, keyless entry and ignition, a rearview camera, an auto-dimming rearview mirror, dual-zone automatic climate control, leather upholstery, eight-way power-adjustable and heated front seats (with driver two-way lumbar adjustment), a 7-inch touchscreen, Apple CarPlay and Android Auto integration, Bluetooth, and an eight-speaker audio system with HD and satellite radio and two USB ports.

The Premium is available with the Luxury package, which adds power-folding mirrors, an 8-inch touchscreen with navigation and a 12-speaker Harman Kardon premium audio system. Additional safety features include rear cross-traffic alert, rear parking sensors and advanced blind-spot monitoring.

The Panoramic Sunroof package (requires Luxury package) adds LED interior lighting and, you guessed it, a panoramic sunroof.

The Technology is one level up, adding the contents of both above packages, along with 19-inch wheels, LED headlights and foglights, automatic wipers, a power-adjustable and heated steering wheel with paddle shifters, a 10-way driver seat (with four-way lumbar adjustment), two-way lumbar adjustment for the front passenger, ventilated front seats, driver-seat memory settings and wireless phone charging.

You can't go any higher than the Limited trim, which equips the Cadenza with power trunk opening and closing, a head-up display, side rear sunshades, a power rear sunshade, upgraded leather upholstery and heated rear seats.

Acceleration from a stop is gradual in every driver mode but Sport. Passing maneuvers require a heavy foot because the transmission is reluctant to downshift and takes a moment even at full throttle. We recorded a 0-to-60 mph sprint time of 6.8 seconds, a few ticks slower than average for the class.

The brake pedal is easy to engage, with very mild braking pressure occurring as soon as you put your foot down. It's also easy to modulate, with predictable increasing effort. In Edmunds testing, a Cadenza Limited came to a stop from 60 mph in 115 feet, shorter than average for a large sedan.

Steering effort is light in the normal Comfort driving mode, firming up slightly when Sport is selected. The steering wheel requires a fair amount of rotation to navigate in turns, and back-to-back transitions get tiring quickly. Steering feel is mostly numb.

Large sedans optimize comfort over athletic ability, and the Cadenza is no exception. A healthy amount of body lean will have you resting on the seat's leg and side bolsters anytime you drive through a corner with some enthusiasm. Mid-corner bumps don't affect the Cadenza at all.

The transmission is smart enough to hold a low gear up steep grades, even in the gas-friendly Eco mode. In the normal Comfort setting, the Cadenza gets into high gears quickly. There's a noticeable lag when leaving from a stop, where the engine gets louder but you don't move until a moment later.

The seats are initially comfortable, with plenty of cushion and cushy leather. Even without the ventilation function, the seats feel breathable. They are best suited for short trips because thigh support isn't great; long-distance driving required multiple adjustments to alleviate driver fatigue.

The comfort-tuned suspension glides over most rough road surfaces, but dips in the asphalt cause the body to lean and rock to the side, more so than in other large sedans. Impacts are better controlled and much less noticeable than in the previous Cadenza.

The cabin is quiet enough that you never need to raise your voice to talk. Wind and tire noise is noticeable but not overpowering, and you will hear the engine's unimpressive groan at low speeds. Vibration at idle is nonexistent to the point that you might think there's an engine start-stop system.

Heated front seats are standard on all Cadenzas, with the midtier Technology trim adding ventilated fronts and a heated steering wheel. Heated rears come only on the Limited. All seats get nice and hot, and the cooling effect is greater than in many rivals. Rear air vents keep passengers happy.

All buttons and knobs on the center stack are within arm's reach of the driver and front passenger. The touchscreen is a little far away, however. Either front occupant will have to lean forward slightly to press the virtual buttons accurately.

Wide doors, a tall door opening, narrow side sills and unobtrusive seat bolsters make it easy to get into and out of the front seats. A gently sloping roofline makes for similarly easy entry and egress for the back row.

The driver seat offers a number of adjustments, including four-way lumbar and an extendable thigh bolster. The power steering wheel telescopes out pretty far, making it easy for tall drivers to find a comfortable position. It's also easy to see over the low hood.

The Cadenza's large interior provides ample room all around for most occupants. Legroom is generous, allowing 6-foot adults to sit behind each other without knees hitting the seatback. Only very tall passengers in a sunroof-equipped Cadenza will brush up against the headliner.

Tall, wide front windows promote excellent forward and side visibility. The rear roof pillars are thick, but the associated small windows help reduce the blind spots. The rear window is generously sized, so it's easy to see out the back.

The Cadenza Limited's materials quality seems appropriate given its price tag. Quilted seat bolsters are an unexpected touch in this class, and thoughtful touches such as a padded driver knee rest are appreciated. Glossy piano black and wood trim do not reflect glaring sunlight.

Front seat occupants get a cubby beneath the center stack and a bin under the armrest to store small items. There's not much in the rear, aside from the seatback map pockets. All doors have a cutout with room for a very small water bottle. Four normally sized cupholders are split between front and rear.

The cargo load floor is large and mostly flat, aside from a slight hump in the middle to provide room for the spare tire jack underneath. Cargo area measures 16 cubic feet, average for the segment but less than in the Impala and Taurus. There is a ski pass-through, but the rear seats don't fold.

Four lower LATCH anchors are hidden beneath plastic covers on the outboard seats that fold down under pressure but cannot be removed. Three upper anchors are located on the rear shelf and are also concealed under covers. All are easy to access.

The 12-speaker Harman Kardon system sounds awesome, with a wide volume range and a surround-sound effect that makes instruments and voices sound closer to the listener. We wish more than just treble, bass and mid were adjustable. Slow responses make the nav system a bit difficult to operate.

Android Auto and Apple CarPlay come on every Cadenza, while the Technology and Limited trims add a wireless phone charging pad under the center stack. Apple CarPlay is unusually difficult to find in the touchscreen menus. There's one USB port in front and another behind the center console.

Adaptive cruise control keeps speed well, exceeding the limit set by just 1 mph on a steep downhill grade. Unfortunately, it's slow to reapply acceleration if the car in front of you has turned or changed lanes. Lane departure warning is too sensitive, triggering an alarm with little provocation.

Kia's voice recognition software could use some work, as the navigation system is easily confused by numbered streets (e.g., "5th Street") and north/south/east/west descriptors. Phone book recognition is better. Siri Eyes Free is available if an iPhone is connected.
