Overview

The Kia K900 Sedan is a full-size sedan that offers premium luxury and is the flagship model of the brand. The 2018 Kia K900 carries forward unchanged this year and is offered in 3 trims. Between 3 trims, the K900 offers 2 powertrains. The base engine is a 3.8L V6 capable of making 311 horsepower and 293 lb-ft of torque while there is also a 420 horsepower-making 5.0L V8 engine. The base powertrain does the 0-60 MPH sprint in 5.3 seconds and yet returns a healthy 25 MPG combined.

The 2018 Kia K900 price starts at $50,900 and it mainly competes with the Genesis G80 Sedan, the Cadillac CT6 Sedan, and the Lincoln Continental Sedan. While we're on the topic of choices, the 3 striking colors the K900 comes in really pull you towards itself. Check out the video below by "NewCarTube" for a detailed walkaround and review of the K900. 

Key observations in the video:

  • Premium exterior design and interior quality
  • Spacious and feature-loaded cabin
  • Exquisite luxuries and technology
  • Strong powertrain and comfortable ride quality
  • High price tag

Buying Advice

While the base V6 Premium offers plenty of creature comforts, it lacks desirable technology and driver assistance features. Our recommendation is for the Luxury trim, which includes upgraded leather upholstery, upgraded power seats with 16-way adjustment, power-reclining and ventilated rear seats, heated wood-trimmed steering wheel with transmission shift paddles, interior wood accents, and a head-up display.
