2015 Kia K900: Hushed Cabin
September 24, 2014
The interior of our long-term 2015 Kia K900 is quiet, like really quiet. The 5.0-liter V8 gives a good rumble when you give it the beans, but this thing is exceptionally quiet on the highway and in city traffic. In fact, it is one of the quietest cars in our long-term fleet. To see just how quiet it is, I turned to our official testing numbers.
Our old long-term 2013 Tesla Model S and 2014 Ram 1500 Ecodiesel are great at drowning out noise, and I've used them as a benchmark for cabin silence before, but even those two have a hard time competing with this big, buttoned up, luxury sedan. Here's how the K900 stacks up against those models and a couple of other flagships from its upscale competitors:
|dB @ Idle||dB @ "Full Throttle"||dB @ 70 mph|
|2015 Kia K900||39.3||69.5||59.5|
|2013 Tesla Model S||36.4||62.5||61.7|
|2014 Ram 1500 EcoDiesel||41.9||65.1||60.2|
|2014 Audi A8 4.0T||40.1||68.4||61.8|
|2014 Mercedes S550||37.5||67.6||60.1|
So while the Kia K900 is marginally louder at full throttle than the other big sedans, it's definitely the quietest at highway speeds and that's no small feat when it's up against vehicles that cost nearly twice as much.
