The EPA rates the 2018 Kia Sedona SX with its 3.3L V6 at 21 MPG combined, a number that isn’t impressive, but one that families and shuttle services find acceptable. This minivan focuses on hauling people and cargo in comfort and style. For the Sedona’s core mission, fuel economy is a secondary consideration, though it still matters.
City and highway performance
The 2018 Kia Sedona SX earns an EPA rating of 18 MPG in the city and 25 MPG on the highway. The city figure reflects the demands of stop-and-go traffic, where the Sedona’s weight and relatively large engine are a disadvantage. The highway figure, while better, isn’t class-leading, because minivans aren’t aerodynamic, and the Sedona’s boxy shape increases wind resistance at higher speeds. The six-speed automatic transmission is generally smooth, but it doesn’t have as many gears as some competitors, which can keep the engine in its most efficient range at cruising speeds. However, for most drivers the real-world difference in fuel costs is less important than the Sedona’s smooth ride, ample cargo space, and long list of standard features.
Annual fuel cost
The EPA estimates the annual fuel cost for the 2018 Kia Sedona SX will be $2,100. This figure is based on driving 15,000 miles per year and using national average fuel prices. Individual costs will vary depending on driving habits, local fuel prices, and the specific mix of city versus highway driving. The $2,100 estimate provides a useful benchmark for comparing the Sedona’s fuel costs to those of other vehicles. Buyers considering the SEDONA MPG across all years should keep this in mind.
Real-world expectations
EPA estimates provide a standardized comparison, but real-world fuel economy often differs. Aggressive driving, heavy loads, and prolonged idling can all reduce MPG. Gentle acceleration, consistent highway speeds, and proper tire inflation can improve fuel economy compared to the EPA estimates. Some owners who track their mileage report figures slightly higher or lower than the official ratings. Expect that your personal experience will vary somewhat from the published numbers.
How it compares
The Chrysler Pacifica, and especially the hybrid version, is a more fuel-efficient minivan. The Pacifica Hybrid achieves 82 MPGe combined when running on electric power and 32 MPG combined once the battery is depleted. The non-hybrid Pacifica achieves around 22 MPG combined. The Honda Odyssey typically achieves around 22 MPG combined. The 2018 Kia Sedona SX is near the lower end of the minivan fuel economy spectrum. Many Sedona buyers prioritize value, features, and styling more than fuel efficiency. Kia fuel economy data reveals that other Kia models offer substantially better MPG figures for those who want to maximize efficiency.
Tips to maximize efficiency
Pay attention to tire pressure. Underinflated tires increase rolling resistance, which makes the engine work harder. Check your tires at least once a month and inflate them to the recommended pressure listed on the sticker inside the driver’s side door.
Avoid aggressive driving habits like rapid acceleration and hard braking. Smooth and steady driving reduces fuel consumption. Anticipate traffic flow and maintain a consistent speed when possible.
Minimize idling. Turn off the engine if you anticipate stopping for more than a minute or two. Modern engines restart quickly, and prolonged idling wastes fuel.
Reduce unnecessary weight. Excess cargo adds to the vehicle’s overall weight, which reduces fuel economy. Remove any unnecessary items from the vehicle, especially heavy objects, to improve MPG.
Consider using cruise control on the highway. Cruise control helps maintain a consistent speed, which can improve fuel economy on long trips. Avoid using cruise control in hilly terrain, as the transmission may downshift frequently, negating fuel savings.
