The 2024 Kia K5 AWD with the 1.6L turbo engine gets 28 MPG combined. It’s not going to win any hypermiling competitions, but it’s a reasonable compromise for buyers who prioritize all-weather traction and distinctive styling in a mainstream sedan. This isn’t a Prius competitor, and Kia knows it. The K5 is targeted toward drivers willing to trade ultimate fuel efficiency for confident grip in snow and rain, wrapped in a more striking package than its rivals.

City and highway performance

The EPA estimates the 2024 Kia K5 AWD 1.6L at 25 MPG in the city and 33 MPG on the highway. The city figure reflects the realities of stop-and-go driving, where the engine spends more time idling or accelerating from a standstill. The highway number showcases the engine’s efficiency at a constant cruising speed, aided by the smooth-shifting 8-speed automatic transmission (S8). In real-world driving, expect your mileage to fluctuate between these two figures depending on your driving style and the conditions.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2024 Kia K5 AWD 1.6L is $1,550. This figure is calculated based on driving 15,000 miles per year and using national averages for fuel prices. Your actual fuel costs will vary depending on how much you drive, the type of driving you do (city vs. highway), and the prevailing fuel prices in your area. Aggressive driving habits can also significantly increase your fuel consumption and subsequently your annual fuel expenses.

Real-world expectations

EPA estimates provide a useful baseline, but real-world MPG can vary. Drivers who spend most of their time in congested urban environments are likely to see fuel economy figures closer to the 25 MPG city rating. Conversely, those who primarily drive on open highways may achieve numbers closer to, or even slightly exceeding, the 33 MPG highway estimate. Driving style, weather conditions, and even tire pressure can all influence fuel consumption. Don’t be surprised if your personal experience differs somewhat from the EPA’s projections.

How it compares

The AWD Kia K5’s fuel economy has to be considered against competitors with similar drivetrains and mission. A comparable Nissan Altima AWD achieves a slightly better 29 MPG combined. Toyota Camry AWD models also hover around 28 MPG combined, but offer no additional benefit to K5 buyers. The Honda Accord no longer offers AWD. Within the Kia family, the K5’s numbers are important compared to other models. For example, checking all Kia fuel economy data illustrates how Kia balances economy in cars such as the K5 against the needs of larger SUVs. These comparisons matter to K5 buyers because they are aware rival vehicles offer comparable performance without the added cost and complexity of AWD. In the K5 they are making an active choice to prioritize traction.

Tips to maximize efficiency

Gentle acceleration and braking are the easiest ways to improve fuel economy, especially in city driving. The K5’s turbocharged engine responds well to a light foot. Avoid aggressive starts and stops, as these maneuvers consume considerably more fuel. Anticipate traffic flow and maintain a steady speed whenever possible.

Proper tire inflation also contributes to better fuel economy. Check your tires regularly and inflate them to the recommended pressure, which can be found on a sticker inside the driver’s side doorjamb. Underinflated tires increase rolling resistance, which reduces fuel efficiency. Consider that the typical K5 AWD buyer is likely in an area where winter tires are used, and these tips are especially relevant as they transition to all-seasons.

Minimize idling. If you anticipate being stopped for more than a minute or two, turn off the engine. Modern engines are designed to restart quickly and efficiently, so you won’t waste much fuel with frequent restarts. This is particularly relevant in colder climates where drivers tend to leave their engines running to warm up the cabin.

Reduce aerodynamic drag by removing unnecessary items. The K5 is not a vehicle typically used with roof racks and cargo carriers, so cleaning up other forms of clutter will have greater impact.

Use cruise control on the highway to maintain a consistent speed and optimize fuel efficiency. Cruise control helps to prevent unintended acceleration or deceleration, which can waste fuel. Be mindful of the road conditions and traffic flow, and disengage cruise control when necessary for safety.
