Kia.com, FuelEconomy.gov and Edmunds.com all have gas mileage information for current model year Kia automobiles, as of 2015. Testing for fuel efficiency ratings is typically performed by the manufacturer in laboratory conditions that meet federally specified guidelines. These reports are submitted to the U.S. Environmental Protection Agency for verification.
The EPA randomly retests vehicles to confirm the validity of the reported data. The actual mileage that a vehicle gets can vary significantly from its rating depending on numerous factors. Those factors include the type of fuel used, vehicle variations, engine break-in, maintenance, and how and where the car is driven. Edmund's allows users to enter some of these variables for a more representative mileage estimate for their type of driving.
