The United Sates Environmental Protection Agency measures the fuel economy of the 2015 Kia Sorento at 20 miles per gallon in the city and 27 miles per gallon on the highway. The combined EPA rating is 23 miles per gallon, though real-world measurements may vary.
An automobile's fuel economy is the fuel efficiency relationship between travel distance and fuel consumption. EPA ratings presume drivers are in the city 55 percent of the time and on the highway 45 percent of the time. Fuel economy lessens oil dependence costs, reduces climate change, saves drivers money and increases energy sustainability, according to Fueleconomy.gov.
