27 MPG combined is a respectable figure for the 2022 Kia K5 with the 2.5L four-cylinder engine. This isn’t a hybrid, nor is it a dedicated efficiency champion. The K5 2.5 is a stylish, comfortable, and well-equipped mid-size sedan aimed at buyers who prioritize value, design, and interior space over outright fuel sipping, although 27 MPG from a non-hybrid sedan is nothing to be ashamed of.

City and highway performance

The EPA estimates the K5 2.5L at 24 MPG in the city and 32 MPG on the highway. The city figure reflects the stop-and-go driving conditions typical of urban environments, where the engine spends more time idling or accelerating from a standstill, which reduces fuel economy. The highway figure represents a more consistent speed with less demand on the engine, resulting in better efficiency. The K5’s eight-speed automatic transmission (AM-S8) even in this non-sporting application, plays a crucial role in optimizing fuel economy at higher speeds, keeping the engine in its most efficient RPM range. These numbers reflect a balance Kia struck between performance and efficiency for a buyer who wants a good looking sedan that’s easy on the wallet, both at the point of purchase and at the pump.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2022 Kia K5 2.5L at $1,600. This figure is based on driving 15,000 miles per year and using national average fuel prices. It’s important to remember that your actual fuel costs may vary depending on your driving habits, the type of gasoline you use, and fluctuations in fuel prices.

If you drive significantly more or less than 15,000 miles annually, or if fuel prices in your area are substantially higher or lower than the national average, your actual fuel costs will differ accordingly. Still, $1,600 is a good benchmark when you’re considering the total cost of ownership of the K5 2.5, and a relatively attractive figure within its competitive set.

Real-world expectations

While the EPA estimates provide a useful baseline, real-world fuel economy often differs. Factors such as driving style, traffic conditions, and even tire pressure can impact the actual MPG you achieve. Aggressive acceleration, hard braking, and prolonged idling will all decrease fuel economy.

Similarly, consistently driving in heavy traffic or on poorly maintained roads can also lead to lower MPG. Keeping tires properly inflated and performing regular maintenance, such as oil changes and air filter replacements, will help to maintain optimal fuel efficiency. Consider these factors when evaluating the 2022 K5 MPG across all years.

How it compares

The mid-size sedan market is filled with efficient options, and the K5 2.5 stacks up competitively. The Toyota Camry achieves an EPA-estimated 28 MPG combined in its base 2.5L configuration, a negligible difference, but still worth calling out. The Honda Accord with its 1.5L turbo manages 33 MPG combined, a noticeable advantage. However, those seeking more power in the Accord will find its 2.0L turbo achieves only 26 MPG combined, putting it slightly behind the K5 2.5. These comparisons show that the K5 2.5 strikes a decent balance; a bit thriftier than the thirstier versions of its competitors, but not quite matching the stellar efficiency of the hyper-efficient trims.

Tips to maximize efficiency

Gentle acceleration is key to maximizing fuel economy in the K5 2.5. Avoid aggressive starts and maintain a smooth, steady pace. The car’s eight-speed automatic will do its best work when you’re not demanding sudden bursts of power, allowing it to keep the engine in its optimal efficiency range. Gradual inputs are rewarded with gradual, optimized gear changes.

Pay attention to tire pressure. Underinflated tires increase rolling resistance, forcing the engine to work harder and burn more fuel. Check your tire pressure regularly and inflate them to the recommended level, which can be found on a sticker in the driver’s side doorjamb. Properly inflated tires will also improve handling and extend tire life.

Reduce unnecessary weight inside the vehicle. Extra cargo adds to the vehicle’s overall weight, which negatively impacts fuel efficiency. Remove any items from the trunk or passenger compartment that are not essential, especially heavy items. This is basic advice, but it’s surprising how much junk can accumulate in a car over time, and every little bit counts.

Use cruise control on the highway to maintain a consistent speed. This helps to avoid unnecessary acceleration and deceleration, which can waste fuel. However, be mindful of traffic conditions and adjust your speed accordingly. Cruise control isn’t magic, but at a steady 70 MPH, it’s more efficient than most drivers could ever hope to be.
