Kia K900 engines, horsepower and mpg

Horsepower and torque are left blank: Kia's US spec pages for this discontinued model are no longer online, and we only publish ratings from official Kia sources. Engines, transmissions and mpg come from EPA records. EPA lists premium fuel for the V8 and the 3.3L turbo V6, and regular fuel for the 3.8L V6.
