The 2023 Kia Stinger RWD with its 3.3L 6-cylinder engine gets 20 MPG combined, which is the price for its accessible performance. It’s not a hybrid or a fuel-sipping commuter, but a rear-wheel-drive sport sedan with a potent twin-turbo V6 designed to offer both practicality and driving enjoyment. Buyers accept this fuel economy because they prioritize the Stinger’s style, speed, and value over being extremely efficient. They are willing to pay more at the pump for the driving experience.

City and highway performance

The EPA estimates of 18 MPG in the city and 25 MPG on the highway reflect the Stinger’s character. Stop-and-go city driving, with its constant acceleration and braking, impacts fuel consumption, especially with a powerful engine. However, the 25 MPG highway figure shows that the Stinger can achieve respectable efficiency during steady-state cruising. The eight-speed automatic transmission plays a key role here, offering smooth and responsive shifts while also maximizing fuel economy at higher speeds by keeping the engine at its optimal RPM.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 Kia Stinger RWD 3.3L at $2,900. This figure is calculated based on driving 15,000 miles per year and using the national average fuel price. It’s a helpful data point for comparing the running costs of different vehicles, but your actual fuel expenses will vary depending on your driving habits, local fuel prices, and the type of fuel you use. The Stinger doesn’t require premium fuel, but some drivers find that it delivers slightly better performance and fuel economy when using it.

Real-world expectations

While the EPA estimates provide a standard, real-world fuel economy often differs. Stinger drivers who frequently use the engine’s power can expect lower MPG than the EPA figures suggest. However, those who prioritize fuel efficiency and drive more conservatively may see numbers closer to, or even slightly exceeding, the official estimates. Factors like tire pressure, vehicle maintenance, and weather conditions also play a role. The STINGER MPG will vary year-to-year, so consult STINGER MPG across all years.

How it compares

Competitors to the Stinger exist, each with its own strengths and weaknesses. The Acura TLX, for example, delivers a combined EPA rating of 25 MPG with its 2.0L turbocharged four-cylinder engine, a significant advantage over the Stinger. However, the TLX with the 3.0L turbocharged V6 drops to 21 MPG combined and doesn’t deliver the same feel as the Stinger, so the Stinger RWD buyer likely appreciates the greater power when buying and accepts the lower fuel economy. The BMW 330i, a benchmark sport sedan, achieves 29 MPG combined, offering performance and efficiency that can tempt some Stinger buyers. The Genesis G70, closely related to the Stinger, achieves an EPA combined of 21 MPG with its 3.3L V6 and RWD.

Tips to maximize efficiency

Maintain optimal tire pressure. Often overlooked, proper tire inflation reduces rolling resistance and improves fuel economy. Check your tire pressure regularly, and adhere to the pressures listed on the door placard. A few extra PSI can make a difference over time.

Anticipate traffic flow and practice smooth acceleration and braking. The Stinger’s powerful engine responds quickly to throttle inputs, but aggressive acceleration wastes fuel. By anticipating traffic patterns and maintaining a consistent speed, you’ll minimize unnecessary braking and acceleration, improving your MPG.

Avoid excessive idling. Modern engines are designed to operate efficiently while moving, and prolonged idling wastes fuel. If you anticipate a wait of more than a minute or two, shut off the engine. This is relevant in urban environments where traffic congestion can lead to extended periods of standstill.

Use cruise control on the highway. Cruise control helps maintain a consistent speed, minimizing changes in fuel consumption. It’s effective on relatively flat stretches of highway. Using cruise control on long drives will substantially increase fuel mileage.

Keep up with routine maintenance. A well-maintained engine operates more efficiently. Follow the recommended maintenance schedule outlined in your owner’s manual, including regular oil changes, air filter replacements, and spark plug inspections. Failing to maintain the car can lead to decreased performance and lower fuel economy.
