“The car is wonderful. It seems as good as a comparable BMW or Mercedes at a much lower price and warranty.”
2015 Kia K900: What's New, Specs & Features
Last updated August 4, 2026
The biggest change for 2015 is the K900 itself: this was Kia’s all-new U.S.-market flagship sedan and its first model year here. It debuted as a full-size, rear-wheel-drive luxury car centered on a 420-hp V8.
About the 2015 Kia K900
1st generation K900/K9 (KH), U.S. debut year / first model year.
Kia positioned the K900 as a big, quiet rear-wheel-drive flagship for shoppers who wanted space, smooth V8 power, and a long list of luxury features without paying for a traditional luxury badge. Kia framed it as proof the brand had moved upscale. Its core appeal was comfort, rear-seat room, understated styling, and strong standard equipment, not sport-sedan handling or flashy brand image.
Kia positioned the Premium as the more accessible flagship, with a panoramic sunroof, a 9.2-inch navigation screen, heated and ventilated front seats, and heated rear outboard seats. The Luxury adds Nappa leather, a 17-speaker Lexicon audio system, LED headlights, blind-spot monitoring, and lane-departure warning for a more complete luxury experience.

2015 Kia K900 Reviews
What owners are saying about the 2015 Kia K900.
4.3
2015 Kia K900
(60 reviews)
“I totally would not recommend KIA to anyone. My car is three months old and been in the shop three times already. I need to put it back in the shop once again for the same reason as the first three times.”
“For the K900 to be accepted as a true luxury vehicle, Kia needs to alter and differentiate the design since it now looks too similar to the Optima and Cadenza which are lower level vehicles.”
