2015 Kia K900

Motor Trend logo Motor Trend 2/19/2015 Stefan Ogbac

New for 2015

The Kia K900 is an all-new model for the 2015 model year.

Vehicle Summary

The 2015 Kia K900 is a rear-drive full-size luxury sedan slotting above the front-drive, full-size Cadenza. It's new to the U.S. market for the 2015 model year and has been on sale in other markets as the Quoris and the K9 in South Korea since 2012.


The 2015 Kia K900 is powered by a 5.0-liter V-8 with 420 hp and 376 lb-ft. A 311-hp 3.8-liter V-6 is expected to arrive for the 2016 or 2017 model year. The 2015 model's V-8 is paired to an eight-speed automatic transmission. Fuel economy is mediocre, with the V-8 rated at 15/23 mpg.

Comfort is one of the 2015 K900's strong suits, with a suspension tuned for soaking up road imperfections with little harshness being transmitted to the cabin. Handling is lackluster due to the car's soft chassis, which is the result of Kia's focus on giving buyers a "traditional luxury-car experience."

Inside, the 2015 K900 is offered with a long list of standard and optional features such as Nappa leather upholstery with contrast piping, a 12.3-inch digital instrument cluster, head-up display, a 9.2-inch screen for the navigation and infotainment systems, heated front and rear seats, and reclining rear seats. Driver aids are also plentiful with lane departure warning, around-view parking monitor, and blind spot warning system all available. Refinement is impressive, with little outside noise entering the cabin.

The 2015 Kia K900 has not been crash tested by the NHTSA or the IIHS.

What We Think

As a traditional luxury sedan, the 2015 Kia K900 excels because it offers a smooth ride and a comfortable, well-built interior. In a First Test review, we said that the car is "the quietest Kia ever" with little noise entering the cabin even at high speeds, and has a "relaxing character." Driving dynamics, however, are a weak point due to the car's strong emphasis on comfort, which detracts from its handling. In one long-term update review, we noted that the car has a lot of body roll due to its ultra-soft suspension. The K900 V-8's fuel economy and shorter driving range (compared to more expensive competitors) is another issue.
