Owners of the 2016 Kia Sedona SX with the smooth-operating 3.3L V6 engine experience 21 MPG combined. No one buys a minivan expecting Prius-like fuel efficiency, of course. This vehicle is chosen for its large interior, its ability to carry up to eight passengers (in some trims), and its family-friendly features. The fuel economy is simply a trade-off for those who need this kind of practicality.

City and highway performance

The Sedona SX’s EPA estimates are 18 MPG in the city and 25 MPG on the highway. The city figure reflects the realities of stop-and-go family life, school drop-offs, errand runs, and the general grind of suburban traffic. The V6 provides enough power, but it’s working to move a relatively large vehicle. The 25 MPG highway number is easier to achieve on long road trips, where consistent speeds allow the engine to settle into its most efficient operating range. However, if you load up the Sedona with passengers and luggage, even that highway figure will decrease.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2016 Kia Sedona SX at $2,100. This figure is based on driving 15,000 miles per year, using the EPA’s projected fuel price based on national averages. Remember that this is just an estimate. Your actual fuel costs will vary depending on your driving habits, the type of driving you do (city vs. highway), and the fuel prices in your area. If you live in an area with higher fuel costs, or if you tend to drive more aggressively, expect to spend more than $2,100 annually. If you drive less than 15,000 miles per year or drive gently, you could spend less.

Real-world expectations

While the EPA estimates provide a useful baseline, real-world fuel economy can be different. Many Sedona SX owners report numbers close to the EPA estimates, particularly on longer trips. However, some evidence suggests that achieving the 18 MPG city rating consistently can be difficult, especially in congested areas, and if you frequently use the Sedona for towing or hauling heavy loads, expect a significant decrease in fuel economy. The 6-speed automatic transmission is generally smooth and responsive, but it can sometimes hunt for gears in hilly terrain, which can also affect efficiency.

How it compares

The 2016 Kia Sedona SX’s fuel economy is similar to other minivans of its time. The Honda Odyssey, for example, was rated at 19 MPG combined for its V6 engine, slightly ahead. The Toyota Sienna, another strong competitor, achieved an EPA-estimated 20 MPG combined with its V6 and front-wheel drive. Even the Chrysler Pacifica, which later became available as a hybrid, started with a similar 18/25 MPG city/highway rating for its gasoline-only models. These differences are measurable, but probably won’t decide minivan buyers. Someone choosing between these vehicles is more likely prioritizing layout, features, and reliability, accepting the fuel economy as a necessary compromise. Check out SEDONA MPG across all years.

Tips to maximize efficiency

Regular maintenance is important. Ensure your Sedona SX’s tires are properly inflated to the recommended pressure. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel.

Drive smoothly and avoid aggressive acceleration and braking. The Sedona’s V6 offers plenty of power, but using it wisely will significantly improve fuel economy. Anticipate traffic flow and maintain a steady pace when possible.

Reduce unnecessary weight. Remove any items from the vehicle that you don’t need to carry regularly. Extra weight puts additional strain on the engine, reducing fuel efficiency, especially when carrying cargo in the rear cargo area.

Minimize idling. If you’re stopped for more than a minute or two, turn off the engine. Modern engines are designed to restart quickly and efficiently, and idling wastes fuel, which is especially important during those school pickup lines.
