2018 Kia Optima 1.6L: Fuel Economy Analysis

The 2018 Kia Optima with the 1.6L turbocharged four-cylinder engine gets 31 MPG combined. This is a strong number, and a key part of this Optima’s appeal to budget-conscious buyers who still want a stylish and well-equipped mid-size sedan. This isn’t a hybrid built for ultimate efficiency, but a mainstream car offering a reasonable blend of performance and fuel savings.

City and highway performance

The EPA estimates for the 2018 Optima 1.6T are 28 MPG in the city and 37 MPG on the highway. The city figure is respectable for a car of this size and power, reflecting the engine’s stop-start system that helps reduce fuel consumption during urban driving. The 37 MPG highway rating is where this Optima shines, making it a comfortable and economical choice for commuters or those who frequently embark on longer road trips. This fuel efficiency is partly thanks to the 7-speed dual-clutch transmission (DCT), which is geared for efficient cruising at higher speeds.

Annual Fuel Cost

According to the EPA, the estimated annual fuel cost for the 2018 Kia Optima 1.6T is $1,400. This figure is based on driving 15,000 miles per year and using national average fuel prices. Individual results may vary depending on driving habits and local fuel costs, but $1,400 provides a useful benchmark for comparing the Optima 1.6T to other vehicles in its class. Keeping fuel costs under this amount is a significant factor for many buyers choosing this model. Review all Kia fuel economy data for a broader context.

Real-World Expectations

While the EPA estimates provide a standardized benchmark, real-world fuel economy can vary. Aggressive driving, heavy traffic, and extreme weather conditions can all negatively impact fuel efficiency. But, many owners of the 2018 Optima 1.6T report achieving fuel economy figures close to the EPA estimates in normal driving conditions. The key to maximizing fuel economy in this car is to adopt a smooth and consistent driving style, avoiding excessive acceleration and hard braking. Regular maintenance, such as keeping tires properly inflated and ensuring the engine is properly tuned, can also help to maintain optimal fuel efficiency.

How It Compares

The 2018 Kia Optima 1.6T compares well against its competitors in terms of fuel economy. The Honda Accord 1.5T, for example, offers similar EPA ratings of 30 MPG combined, 26 MPG city, and 35 MPG highway. The Toyota Camry LE, with its 2.5L four-cylinder, achieves 32 MPG combined, 28 MPG city, and 39 MPG highway, giving only a slight edge on the highway. Therefore, the Optima 1.6T sits right in the mix of fuel-efficient family sedans without the additional cost of a hybrid. These comparisons matter to the Optima buyer because they are often weighing overall value, and fuel economy plays a big role.

Tips to maximize efficiency

Use the Optima 1.6T’s Eco mode. This setting optimizes engine and transmission performance for maximum fuel efficiency. It might slightly reduce throttle response, but the impact on fuel economy can be noticeable, especially during city driving.

Monitor your tire pressure regularly. Underinflated tires increase rolling resistance, which reduces fuel economy. The recommended tire pressure for the 2018 Optima can be found on a sticker located on the driver’s side doorjamb. Keeping your tires properly inflated improves fuel efficiency, enhances safety, and extends tire life.

Avoid unnecessary idling. Idling consumes fuel without moving the car. If you anticipate sitting in one place for more than a minute, it is more fuel-efficient to turn off the engine. The Optima 1.6T’s start-stop system automatically shuts off the engine at stoplights and other brief stops, conserving fuel.

Minimize the use of accessories that put a strain on the engine. Air conditioning, for example, can significantly reduce fuel economy, especially in hot weather. Use the air conditioning sparingly and only when necessary. When possible, opt for the recirculate setting to cool the cabin more efficiently.
