29 MPG combined is an unremarkable figure, but for the 2018 Kia Optima FE with its 2.4L four-cylinder, it represents its mission: efficient and affordable transportation for families or individuals who prioritize value and reliability over thrills. This isn’t a hybrid chasing record numbers, nor is it a performance sedan; it’s a well-built car designed to deliver practical fuel economy.

City and highway performance

The EPA estimates of 25 MPG in the city and 36 MPG on the highway accurately reflect the Optima FE’s performance in typical driving conditions. The 2.4L engine, paired with a smooth-shifting six-speed automatic transmission (S6), provides adequate power for everyday commuting and long road trips. The city figure is adequate, but the highway number is where the Optima FE shines, making it a solid choice for those who rack up significant mileage. This balance makes the 2018 Optima FE a capable all-rounder, satisfying the needs of those who spend time in urban areas and on interstates.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2018 Kia Optima FE 2.4L to be $1,500. This figure is based on driving 15,000 miles per year and national average fuel prices. The lower annual fuel cost is a selling point for budget-conscious buyers considering the Optima FE. It directly translates to lower running costs, making it a smart financial choice for those seeking reliable and economical transportation.

Real-world expectations

While EPA estimates provide a standardized benchmark, real-world fuel economy can vary based on driving habits, traffic conditions, and vehicle maintenance. Optima FE owners can expect fuel economy to hover around the EPA’s 29 MPG combined figure with conscientious driving. Aggressive acceleration and frequent hard braking will negatively impact fuel efficiency, as will neglecting routine maintenance, such as tire inflation and oil changes. However, with mindful driving techniques, achieving or exceeding the EPA estimates is possible.

How it compares

In the mid-size sedan segment, the 2018 Kia Optima FE 2.4L is competitive. The Toyota Camry LE, for instance, boasts a slightly higher 32 MPG combined from its base engine. The Honda Accord LX offers a comparable 30 MPG combined with its 1.5T engine. The Hyundai Sonata SE, sharing its platform with the Optima, achieves similar figures around 28 MPG combined. The Optima FE isn’t the leader in fuel economy, but it represents a strong value when considering its features, reliability, and price. The Chrysler 200, which had been a direct competitor, has since been discontinued, further solidifying the Optima’s place in the market for economical mid-size sedans.

Tips to maximize efficiency

Pay attention to tire pressures. Properly inflated tires reduce rolling resistance, which directly improves fuel economy. Check your tire pressures regularly and inflate them to the recommended levels found on the driver’s side door jamb. Even a slight drop in pressure can noticeably decrease your MPG.

Use cruise control on the highway to maintain a constant speed, minimizing unnecessary acceleration and deceleration. The Optima FE’s six-speed automatic is programmed to select the most efficient gear at steady speeds, helping you maximize fuel efficiency during long drives.

Avoid aggressive acceleration and hard braking. Gradual acceleration and smooth deceleration are more fuel-efficient. Anticipate traffic flow and maintain a safe following distance to minimize the need for sudden stops and starts in the Optima FE.

Lighten the load. Excess weight in your vehicle reduces fuel economy. Remove any unnecessary items from the trunk and passenger cabin. Hauling around extra weight places additional strain on the engine, causing it to consume more fuel.

Keep up with regular maintenance. A well-maintained engine runs more efficiently. Follow the recommended maintenance schedule in your owner’s manual, including oil changes, air filter replacements, and spark plug checks. A healthy engine will deliver optimal performance and fuel economy.
