20 MPG combined is what you get for driving a 2023 Kia Stinger AWD with the 3.3L twin-turbo V6. It’s not stellar, and it certainly lags behind the four-cylinder Stinger, but it’s the figure anyone considering this car has already factored into their ownership experience. This isn’t about squeezing every last mile from a gallon; it’s about enjoying performance, style, and practicality that few cars at this price point can match.

City and highway performance

The EPA estimates for the 2023 Kia Stinger AWD 3.3L V6 are 17 MPG in the city and 24 MPG on the highway. The city number reflects stop-and-go traffic and the engine needing to work harder to overcome inertia. The highway figure is more representative of steady-state cruising, where the eight-speed automatic transmission can settle into its higher gears and the engine operates more efficiently. Remember that these numbers are derived from a standardized testing procedure, and individual results will vary based on driving style, traffic conditions, and environmental factors.

Annual fuel cost

The EPA estimates the annual fuel cost for this Stinger configuration to be $2,900. This figure is based on driving 15,000 miles per year and using national average fuel prices. Obviously, if you drive significantly more or less than 15,000 miles, or if fuel prices in your area are higher or lower than the national average, your actual fuel costs will vary. The EPA uses these standardized calculations to provide a baseline for comparing the fuel costs of different vehicles, including all Kia fuel economy data.

Real-world expectations

While the EPA provides a standardized estimate, real-world fuel economy often differs. Stinger drivers who frequently exploit the engine’s power, and let’s be honest, the temptation is strong, will likely see numbers closer to the city rating, if not slightly lower. Conversely, those who prioritize smooth acceleration and consistent highway speeds might be able to achieve or even slightly exceed the 24 MPG highway estimate. The key is to be mindful of your driving habits and adjust accordingly if you want to maximize fuel efficiency. Factors like tire pressure and vehicle maintenance also play a role.

How it compares

The Stinger’s fuel economy places it in a specific segment of the market. As alternatives, the Acura TLX Type S, with its 355-horsepower turbocharged V6 and standard SH-AWD, delivers an EPA-estimated 21 MPG combined. The BMW M340i xDrive, a frequent Stinger rival, manages a slightly better 26 MPG combined thanks to its mild-hybrid system enhancing the engine. A Lexus IS350 AWD rates at 22 MPG combined. These comparisons highlight that while the Stinger offers strong performance, other options exist for buyers seeking slightly better fuel efficiency in a similar performance bracket. Always check the

Tips to maximize efficiency

One of the most effective ways to improve fuel economy in the Stinger is to be gentle with the throttle. The Stinger’s V6 responds eagerly to even small inputs, but aggressive acceleration burns fuel. Smooth, gradual acceleration allows the engine to operate more efficiently. Resist the urge to constantly pass or weave through traffic, as these maneuvers require frequent changes in speed and put extra strain on the engine.

Maintaining proper tire inflation is critical for fuel efficiency. Underinflated tires increase rolling resistance, which forces the engine to work harder. Check your tire pressure regularly, ideally every few weeks, and inflate them to the manufacturer’s recommended pressure, which can be found on a sticker on the driver’s side doorjamb. Using the correct tire pressure not only improves fuel economy but also extends tire life and enhances handling.

Avoid unnecessary idling. Modern engines are designed to be more efficient when running than when idling for extended periods. If you anticipate being stopped for more than a minute, it’s generally more fuel-efficient to turn off the engine. The Stinger’s engine restart is quick, so you won’t experience any significant delay when it’s time to move again.

Take advantage of the Stinger’s different driving modes. The “Eco” mode, if equipped, typically adjusts throttle response and transmission shift points to prioritize fuel efficiency. While it may slightly reduce performance, it can make a noticeable difference in fuel consumption, especially during city driving. Experiment with the different modes and choose the one that best suits your driving conditions and priorities.
