27 MPG combined. That figure for the 2019 Kia Optima 2.4L isn’t going to win any hypermiling contests, but it’s a solid middle ground and an acceptable fuel economy number for what this car is: a comfortable, reliable, and affordable mid-size sedan. The Optima appeals to buyers who prioritize value, space, and ease of use over fuel efficiency. They’re looking for a practical family car or a comfortable commuter, and the 2.4L engine delivers adequate power without costing too much at the pump.

City and highway performance

The EPA estimates for the Optima 2.4L break down to 24 MPG in the city and 33 MPG on the highway. The city figure reflects how the engine behaves in stop-and-go traffic, where frequent acceleration and idling reduce fuel economy. The six-speed automatic transmission shifts smoothly and unobtrusively, but isn’t tuned for fuel saving during urban driving. On the highway, however, the Optima settles into a more efficient cruise. 33 MPG is achievable on longer journeys, making it a reasonable choice for road trips or daily commutes that involve significant highway mileage. The engine doesn’t feel strained at higher speeds, providing adequate power for passing without frequent downshifts.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2019 Kia Optima 2.4L at $1,600. This figure is based on driving 15,000 miles per year and using national average fuel prices at the time of testing. Your actual fuel costs will vary depending on your driving habits, the type of driving you do (city vs. highway), and where you live; fuel prices vary considerably by region. The $1,600 figure provides a benchmark for comparing the Optima 2.4L’s fuel costs against other vehicles. Drivers covering significantly more than 15,000 miles annually should anticipate spending more on fuel.

Real-world expectations

While EPA estimates provide a standardized measure, real-world fuel economy often differs due to individual driving styles, terrain, and weather conditions. Owners of the 2019 Optima 2.4L report achieving figures close to the EPA estimates, particularly on longer highway drives. However, those who spend most of their time in congested urban areas may see slightly lower MPG numbers. Aggressive acceleration and hard braking can also negatively impact fuel economy. Regular maintenance, such as keeping tires properly inflated and changing the engine oil on schedule, can help maintain good fuel efficiency. The “combined” 27 MPG is a weighted average, not necessarily what any individual driver will experience consistently.

How it compares

The 2019 Optima 2.4L competes in a crowded segment of mid-size sedans. The Honda Accord 1.5T achieves a combined rating of 33 MPG, offering better fuel economy. The Toyota Camry LE with its 2.5L engine nets 32 MPG combined, also outpacing the Optima. The Hyundai Sonata, mechanically similar to the Optima, also offers comparable fuel economy depending on the trim. These comparisons are important for buyers who prioritize fuel efficiency. However, the Optima often offers a more attractive price point or a longer warranty, factors which may sway buyers willing to accept slightly lower MPG. The Optima’s fuel economy is a trade-off they’re willing to make compared to competitors.

Tips to maximize efficiency

Gentle acceleration and smooth braking are the most effective ways to improve the fuel economy of the 2019 Kia Optima 2.4L. Avoid aggressive starts from stoplights and anticipate traffic flow to minimize the need for hard braking. This engine and transmission combination responds well to a relaxed driving style, rewarding drivers with better MPG in everyday situations. Keeping tires properly inflated is another basic factor. Check your tire pressure regularly and maintain it at the recommended level, which is typically found on a sticker inside the driver’s side doorjamb. Underinflated tires increase rolling resistance, reducing fuel efficiency.

Minimize idling time. If you’re stopped for more than a minute or two, it’s more efficient to turn off the engine than to let it idle. Modern engines start quickly and reliably, so shutting down the engine during extended stops can noticeably improve fuel economy, particularly in city driving. Carrying excess weight in the vehicle also reduces fuel efficiency, forcing the engine to work harder. Remove any unnecessary items from the trunk and passenger compartment.

Consider using cruise control on the highway. Cruise control helps maintain a consistent speed, preventing unnecessary acceleration and deceleration, which can save fuel. However, avoid using cruise control in hilly terrain, as the system may overcompensate when climbing hills, leading to reduced fuel economy. Regular maintenance, including oil changes, air filter replacements, and spark plug maintenance, ensures the engine is operating efficiently. A well-maintained engine burns fuel more cleanly and efficiently.

Exploring OPTIMA MPG across all years can help you determine whether its driving habits have changed dramatically since other iterations of the Kia sedan. To get a wider scope, compare all Kia fuel economy data to other models produced by the manufacturer.
