The 31 MPG combined fuel economy of the 2017 Kia Optima 1.6L might not break any records, but it’s a significant achievement for a mid-size sedan focused on value and comfort. This engine configuration is for a specific buyer: someone who wants a refined, well-equipped car that doesn’t consume as much fuel as a larger engine, or cost as much as a pricier hybrid. They accept a moderate reduction in acceleration for the fuel savings and smooth operation of this powertrain.

City and highway performance

The EPA estimates of 28 MPG in the city and 37 MPG on the highway show where this Optima performs best. The higher highway figure is particularly good for commuters or those who take frequent road trips. The 1.6L engine, with a seven-speed dual-clutch transmission (DCT), operates efficiently at steady speeds. Stop-and-go city driving lowers fuel economy, but the DCT helps reduce some typical automatic transmission losses. For the best fuel economy, drive with a light touch, letting the transmission upshift quickly and keep the engine in its optimal efficiency range.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2017 Kia Optima 1.6L at $1,400. This is based on driving 15,000 miles per year and national average fuel prices. It’s a standardized calculation that provides a benchmark for comparing fuel costs across different vehicles. Actual fuel costs will change based on driving habits, local fuel prices, and fuel type. However, the $1,400 figure is a realistic estimate for the typical Optima 1.6L driver.

Real-world expectations

While the EPA estimates are a good starting point, real-world fuel economy often differs. Driving style, traffic, and tire pressure can change the MPG you get. Drivers who are more aggressive or frequently in heavy traffic might see figures closer to the city estimate, while those who accelerate gently and drive at consistent speeds on the highway may exceed 37 MPG. Regular maintenance, including oil changes and proper tire inflation, is critical for keeping fuel efficiency high.

How it compares

The 2017 Kia Optima 1.6L competes well with other mid-size sedans of the time. The 2017 Honda Accord with its base 2.4L engine gets slightly better combined fuel economy at 30 MPG city/36 MPG highway, but the Optima’s 1.6L is close, and often at a better price. A 2017 Toyota Camry with its 2.5L engine achieves about 24 MPG city and 33 MPG highway, less than the Optima. The important thing is who the target buyer is: someone who wants a balance of price and features with decent fuel economy. They might not need the best MPG, but they want a smart, well-rounded car. For those interested in comparing all Kia fuel economy data, detailed specifications are available. Comparing the OPTIMA MPG across all years shows how its fuel efficiency has changed.

Tips to maximize efficiency

The seven-speed DCT in the Optima 1.6L shifts early to save fuel. Accelerate smoothly and gradually, letting the transmission shift into higher gears quickly. Avoid hard acceleration and braking, which make the transmission downshift and burn more fuel. Try to anticipate traffic and keep a consistent speed when possible.

Tire pressure is very important for fuel economy. Check it regularly, at least monthly, and before long trips. Inflate your tires to the pressure on the sticker on the driver’s side doorjamb. Underinflated tires increase rolling resistance, reducing fuel efficiency.Checking tire pressure with a gauge can result in fuel savings over time.

Remove extra weight from the vehicle. Cargo in the trunk or backseat adds weight, making the engine work harder and use more fuel. Remove items you don’t need regularly, like sporting equipment, tools, or heavy boxes. Even small weight changes can improve fuel economy, especially in city driving.

Avoid idling for too long. Turn off the engine if you’re stopped for more than a minute or two. Modern engines restart quickly and efficiently, and idling wastes fuel. This is especially important in urban areas with stoplights and traffic. Restarting uses a small burst of fuel, but less than idling for a long time.
