Scorecard

Performance: 7.4

The 2017 Kia K900 has a smooth ride and delivers the relaxed, quiet driving experience that a luxury car should. Its standard V6 engine is sufficiently powerful, and its optional V8 is strong. Both are matched with a well-behaved automatic transmission. Though comfortable, the K900 isn’t as agile as some of its class rivals. Instead, it biases ride quality over sharp handling.

  • "Supple gas pedal and easy-to-modulate brakes make the K900 driver-friendly. The automatic transmission shifts smoothly, though with eight speeds it will downshift up grades." -- Edmunds
  • "Kia's 2017 K900 luxury sedan is a big car that favors a comfortable ride over a rigid attitude. To that end, the K900 won't perform like a BMW 7 Series, Audi A8 or Cadillac CT6, and maybe that's a good thing." -- Kelley Blue Book
  • "Kia isn't as adept at tuning a suspension as it is at designing an exterior or outfitting an interior, but the K900 drives the way a luxury sedan should. It feels solid, almost vaultlike from behind the wheel. It's very quiet on the road, and the suspension insulates passengers from road irregularities." -- MSN Autos (2015)

Acceleration and Power

The 2017 Kia K900 comes standard with a 3.8-liter V6 engine that puts out 311 horsepower. A 5.0-liter V8 that produces 420 horsepower is available in the V8 Luxury trim. An eight-speed automatic transmission is standard with both engines. With the V6 engine, the K900 gets an EPA-estimated 17 mpg in the city and 25 mpg on the highway, which is below average for the class. The V8 delivers an even lower 15 mpg in the city and 23 on the highway.

The K900's V6 engine provides adequate acceleration. The V8 has plenty of power, though some class rivals offer stronger engines. The eight-speed automatic transmission delivers quick, silky gear changes and makes sure there’s plenty of torque when you need it.

  • Acceleration is good with the V6 and robust with the 420-horsepower V8 under the hood, but fuel economy takes a considerable hit with the larger engine." -- Kelley Blue Book
  • "With 0-60 mph in 5.7 seconds, it's not as quick as the supercharged/turbocharged six-cylinders from Audi and BMW, but the 420-hp V8 moves the K900 with ease. Extra power is summoned with just a slight prod of the gas pedal. Sounds good, too." -- Edmunds
  • "You'll likely be surprised by the amount of thrust on tap when you stab the right pedal. The K900 loves to go, making it easy to trigger traction control when accelerating from a standstill. Equally impressive are the seamless shifts from the 8-speed transmission, which make the power flow as if there's an endless supply of torque from the engine." -- Autotrader (2016)

Handling and Braking

The Kia K900 comes standard with rear-wheel drive. All-wheel drive is not available. The K900’s suspension provides a smooth, comfortable ride and enables confident handling. Its brakes deliver ample stopping power. The K900 doesn’t steer or corner as sharply as some of its sport-tuned rivals, though.

  • While many luxury cars have morphed into 4-door sports sedans, the K900 pampers its occupants with a soft ride and acceptable levels of cornering and braking. The electric-assist power steering is rather vague, requiring constant minute adjustments. Shifting to the Sport setting somewhat improves the feel, but not the response." -- Kelley Blue Book
  • "Around town, the brakes feel like they have plenty of stopping power. An intuitive pedal feel means it is easy to bring it to a halt exactly where you plan." -- Edmunds
  • "Unlike many luxury pretenders, the K900's cabin feels blissfully devoid of wind or moving noise at highway speeds. Similarly, there's excellent suspension damping over rough surfaces, revealing an impressively adaptable suspension. When it comes to pitching the K900 into corners, this sedan comes across as bigger and heftier, making it feel more like an early Cadillac or Lexus and less like a modern BMW or Mercedes-Benz." -- Autotrader (2016)
