2015 Kia K900 Fuel Economy

6.0
Fuel Economy

In its most luxurious form, the 2015 Kia K900 large four-door sedan with a 5.0-liter V-8 engine and an eight-speed automatic transmission receive a combined rating of 18 mpg (15 mpg city, 23 mpg highway). While we haven’t yet test-driven a K900 fitted with the smaller 3.8-liter V-6 and the same eight-speed automatic, it receives a higher combined rating of 21 mpg (18 mpg city, 27 mpg highway).

Those fuel-efficiency numbers aren’t bad for a large four-door sedan, but they’re far from spectacular. Kia has neither hybrid nor diesel models of the K900—unlike Audi, BMW, and Mercedes-Benz, each of which offers one or the other on its mid-size and large luxury sedans.

The 2015 Kia K900 gets about average fuel economy for V-6 and V-8 luxury sedans, but offers no hybrid or diesel option.
