20 MPG combined is not an outstanding number, but it’s what you can expect from the 2018 Kia Sedona with its 3.3L V6 engine. No one expects Prius-like fuel efficiency from a minivan, but this figure is generally acceptable for families. These buyers prioritize space, practicality, and a comfortable ride. They understand they’re trading lower fuel costs for the ability to haul kids, cargo, and the occasional soccer team.

City and highway performance

The EPA further breaks down the Sedona’s fuel consumption, giving it a rating of 18 MPG in the city and 24 MPG on the highway. This difference is expected, as stop-and-go city driving increases fuel consumption, especially with a naturally aspirated V6 in a vehicle of this size. The highway figure is more appealing and shows the Sedona’s ability to cruise comfortably on long trips. The six-speed automatic transmission shifts smoothly and predictably, but with only six gears, it can be slow to react to quick changes in throttle position. Aggressive highway driving will quickly lower the average below 24 MPG, while a steady pace can lead to slightly better results.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2018 Kia Sedona 3.3L V6 is $2,200. This is based on driving 15,000 miles per year and using national average fuel prices. Your actual fuel costs will depend on your driving habits, the type of driving you do, and local fuel prices. This figure is a useful benchmark, but consider your own situation for a more accurate estimate of your potential spending. The annual fuel cost is a key factor for minivan buyers, but it’s often less important than space and usability.

Real-world expectations

EPA estimates provide a standard, but real-world fuel economy varies based on driving style, load, and conditions. Some Sedona owners report numbers slightly below the EPA estimates, mainly in mixed driving. Expect figures closer to 17-19 MPG in daily use with errands, school runs, and traffic. Highway trips can push the average closer to 24 MPG, but only with careful driving. Regular maintenance, correct tire pressures, and avoiding idling can improve fuel economy and better match the EPA estimates. The SEDONA MPG across all years is very similar.

How it compares

The 2018 Sedona’s fuel economy is similar to others in the minivan class, but some offer slightly better figures. The Honda Odyssey, for example, is rated at 19 MPG city and 28 MPG highway, with a combined estimate of 22 MPG. The Toyota Sienna achieves similar numbers, with EPA ratings of 19 MPG city and 27 MPG highway, for 22 MPG combined in front-wheel-drive models. The Chrysler Pacifica, especially the hybrid, has significantly better fuel economy, but costs more. The Sedona’s fuel economy is a factor in the buying decision. Consumers must also consider the vehicle’s pricing, features, and value. See all Kia fuel economy data.

Tips to Maximize Efficiency

The Sedona’s naturally aspirated V6 responds well to smooth acceleration. Avoid sudden speed increases and try to drive at a steady pace, especially when starting from a stop. The engine doesn’t need high RPMs to perform well around town, so using gentle throttle will help.

Tire pressure is often forgotten when considering fuel economy. Check your tires regularly and inflate them to the recommended pressure, found on the sticker inside the driver’s side doorjamb. Underinflated tires increase rolling resistance, which reduces your MPGs. A simple tire inflator can save you money.

Reduce unnecessary weight in the vehicle. Extra weight forces the engine to work harder and burn more fuel. Regularly clear out unwanted cargo to minimize weight and improve efficiency. An empty third row will be more efficient than a full one.

Plan your trips to avoid unnecessary driving. Combine errands and choose the most direct route to minimize mileage. Avoiding peak traffic can also save fuel by reducing idling time. Route planning apps can help you find the most efficient routes, so use them.
