The Kia K900 is the biggest, most expensive sedan the Korean automaker has yet offered in the U.S.--and its most luxurious offering to date, too.
A new model entry for the 2015 model year, the K900 shares its architecture with the Hyundai Equus, though it comes with a six-cylinder base model that is only available in Hyundai's shorter Genesis sedan. A V-8 engine is an upgrade.MORE: Read our 2015 Kia K900 review
Unlike some other in-your-face Kia designs, the K900 wears almost staid styling. Up front is the corporate grille, flowing into a pulled-back greenhouse and a rear end that looks like a combination of other brands'. All K900s come with Nappa leather trimmings inside, with a choice of wood for the fanciest versions.
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 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.
The K900 shares its 119.9-inch wheelbase with Hyundai's largest model, the Equus. This expansive measure provides extravagant rear-seat legroom and good space up front as well, with places for up to five occupants. Headroom isn't as good as in the more upright Hyundai, since the K900's lower roofline cuts in, especially at the rear.
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.
