About the 2018 Kia K900
1st gen (2015-2018 US), final year before the all-new second-generation 2019 redesign
Kia positioned the K900 as its flagship luxury sedan: a large rear-wheel-drive four-door focused on comfort, quietness, rich materials, and a long list of standard features. The model’s core appeal was giving shoppers full-size luxury-sedan space and amenities without the badge-driven pricing of German and Japanese flagship rivals. For most buyers, the K900’s identity was serene commuting and relaxed highway travel rather than sharp handling or showy performance.
The 2018 K900 is a full-size, rear-wheel-drive luxury sedan offered in V6 and V8 versions. Premium emphasizes quiet comfort and built-in equipment, including navigation, a panoramic sunroof, leather seating, and heated and ventilated front seats. Luxury adds a richer cabin with Nappa leather, a heated wood-trim steering wheel, and a 17-speaker Lexicon audio system.

Frequently asked questions
What changed on the 2018 Kia K900 compared with the 2017 model?
Nothing major changed for 2018. The K900 carried over its rear-wheel-drive layout, V6 and V8 lineup, styling, safety equipment, and cabin technology.
Was 2018 the final year of the first-generation Kia K900?
Yes. The 2018 K900 was the final U.S. model year of the first generation, followed by an all-new second-generation K900 for 2019.
Did the 2018 Kia K900 still offer both V6 and V8 versions?
Yes. The carryover 2018 lineup retained its V6 and V8 structure, with rear-wheel drive and an eight-speed automatic transmission.
How did the 2018 K900 Luxury differ from the Premium trim?
The Luxury trim focused on a more upscale cabin. Its defining features included Nappa leather, a heated wood-trim steering wheel, and a 17-speaker Lexicon audio system, while Premium already included navigation, leather seating, a panoramic sunroof, and heated and ventilated front seats.
Is a 2018 K900 meaningfully different from a 2017 K900?
No. The 2018 K900 is not meaningfully different in equipment or design, so condition, mileage, maintenance history, and trim matter more than the model-year change.
