28 MPG combined is respectable for the 2023 Kia K5 AWD with its 1.6L turbocharged four-cylinder. It’s not going to win any hypermiling competitions, but it’s a reasonable compromise for drivers who value the K5’s stylish design, comfortable interior, and the added confidence of all-wheel drive, especially those living in climates where snow or rain are frequent. This particular K5 variant appeals to buyers who want something more distinctive than a run-of-the-mill sedan, but aren’t willing to sacrifice everyday practicality or spend too much on gas.

City and highway performance

The EPA estimates the 2023 Kia K5 AWD at 25 MPG in the city and 33 MPG on the highway. These are important numbers to understand in the context of how you intend to use the vehicle. The city figure reflects stop-and-go driving, where the turbocharger might be working harder to get the car moving from a standstill. The highway figure suggests the K5 cruises efficiently at higher speeds, likely due to its well-tuned 8-speed automatic transmission which allows the engine to maintain lower RPM. If your daily commute is mostly urban, expect your average to skew closer to that 25 MPG mark.

Conversely, those who frequently undertake longer highway journeys should see results closer to, or even exceeding, the EPA’s 33 MPG estimate.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2023 Kia K5 AWD is $1,550. This is based on driving 15,000 miles per year and using national average fuel prices. It’s a useful benchmark for comparing the K5’s running costs against other vehicles you might be considering. However, this is just an estimate. Your actual fuel costs will vary depending on your individual driving habits, local fuel prices, and how frequently you drive.

Real-world expectations

While the EPA figures provide a solid baseline, real-world fuel economy often differs. Many factors can influence your MPG, including driving style, how well the vehicle is maintained, tire pressure, and even the weather. Aggressive acceleration, frequent hard braking, and carrying heavy loads will all negatively impact fuel economy; smooth, consistent driving and keeping up with routine maintenance, such as oil changes and tire rotations, can help you achieve better results. Online forums, fuel tracking apps, and speaking with current K5 owners can provide valuable insights into what owners are typically achieving in similar driving conditions.

How it compares

The all-wheel-drive K5 isn’t alone in its segment, and comparing its fuel economy to rivals is critical. The Nissan Altima AWD, for example, achieves an EPA-estimated 26 MPG combined, making the K5 slightly more efficient. The Subaru Legacy, famed for its standard all-wheel drive, manages 35 MPG highway. However, it’s important to consider the entire package. While the Subaru might offer better highway mileage, the K5 has a more stylish design and technology. Those who don’t require AWD might consider the front-wheel-drive K5, which achieves better figures. It’s worth exploring K5 MPG across all years and trims to see which configuration best suits your needs. You can also explore all Kia fuel economy data to compare this K5 against other offerings from the brand. The best choice depends on your specific priorities.

Tips to maximize efficiency

The K5’s 1.6L turbo engine is responsive but benefits from a gentle foot. Avoid aggressive acceleration and try to maintain a smooth, even pace. The turbocharger provides a welcome boost of power when needed, but can also consume a significant amount of fuel if used excessively.

Tire pressure is an important factor in fuel economy. Check your tire pressure regularly and inflate them to the recommended PSI (found on a sticker inside the driver’s doorjamb). Underinflated tires increase rolling resistance, reducing fuel efficiency.

Minimize unnecessary weight in the vehicle. Carrying around heavy items in the trunk or back seat can negatively impact fuel economy. Remove any unnecessary items to lighten the load.

Consider using the K5’s drive mode settings. “Sport” mode enhances performance, and “Eco” mode will prioritize fuel efficiency by adjusting throttle response and transmission mapping. Experiment to see the difference in your regular driving conditions.

Idling wastes fuel. If you’re stopped for more than a minute, turn off the engine. Modern cars are designed to restart quickly and efficiently, and you’ll save fuel in the process.
