The Kia K900 is a full-size four-door sedan that was introduced for the 2015 model year. Sharing its styling with the Hyundai Equus, the K900 is Kia's biggest and most powerful vehicle to be sold in the U.S., with a standard V-6 engine that can be upgraded to a V-8.

With a base model powered by a V-6 engine, the K900 has a more frugal alternative to the Equus. The 3.8-liter V-6 is rated at 311 horsepower, and is teamed with an eight-speed automatic. At 420 horsepower, the K900's V-8 option makes it a direct rival for the Equus, and probably puts 6-second 0-60 mph times within reach. It's the most powerful Kia yet, and the brand's first eight-cylinder, and gets a differently tuned eight-speed automatic with a choice of Eco, Normal, and Sport shift modes.
Underpinning the K900 is an independent suspension setup with a subframe for the front coil-and-shock setup--and one for the rear and its five-link design. Electrohydraulic power steering is standard; V-6 cars ride on 18-inch, 50-series tires, while the V-8 gets 19-inchers.
Inside the K900, there's seating for five passengers, and legroom is ample. The K900 rides on a 119.9-inch wheelbase, the same as that in the Equus, though with its slightly lower roofline, there's likely a little less headroom.
The K900 is styled conservatively, with a version of Kia's corporate grille its most significant touch. The roofline is reminiscent of that on the Lexus GS or even the mid-size BMW range. Kia's fitted an interior trimmed in Nappa leather and poplar or sycamore wood on the most luxurious versions.
Kia fits Premium models with a 12-way power driver seat, while 16-way seats are available on the higher trim levels no matter which powertrain is installed. Heating and ventilation are standard for the front seats as well. In the rear, Kia fits the K900 with heated outboard seats and remote controls for the climate control system. A VIP package gets rear-seat ventilation, reclining seatbacks, and power lumbar adjustment.
No crash-test results are available, but with the Equus' track record (it's an IIHS Top Safety Pick), the K900 should fare well. Standard equipment includes parking sensors and both a front and a rearview camera; safety options include a head-up display, a lane-departure warning system, blind-spot monitors, and adaptive cruise control. Some of those become standard on higher-priced versions.
All K900 sedans get standard power features; leather upholstery; a power-close trunklid; steering-wheel audio and phone controls; Bluetooth with audio streaming; auxiliary and USB ports; and satellite and HD radio. The Lexicon audio system sends output to a set of 17 speakers with a total of 900 watts of power. Navigation is also standard equipment, and it's controlled through the latest version of Kia's UVO infotainment system.
