The 2021 Kia Stinger RWD 3.3L gets 20 MPG combined. This is the fuel economy for a rear-drive sport sedan with a potent twin-turbo V6, built to challenge established German marques. The Stinger RWD 3.3L prioritizes thrilling performance. Drivers might prioritize exhilaration over efficiency. This isn’t a family sedan pretending to be a sports car; it’s a genuine performance machine with four doors and a hatchback. Buyers know they’re getting a stylish, capable, engaging drive that doesn’t sip fuel. For them, the 20 MPG is a cost of doing business, a necessary sacrifice for a rewarding ownership experience.

City and highway performance

The EPA estimates the Stinger’s fuel economy at 17 MPG in the city and 25 MPG on the highway. The city figure reflects stop-and-go traffic, where the Stinger’s weight and the engine’s thirst for fuel become apparent. The transmission works to keep it in the right gear, but it’s a performance-oriented powerplant.
The highway number is more appealing. At a steady cruise, the Stinger settles into a more efficient rhythm, allowing the engine to loaf as the aerodynamic shape cuts through the air.

These figures are estimates, and real-world results will vary depending on driving style and conditions. Someone who accelerates quickly will see mileage closer to the city figure, regardless of location, while a conservative driver could beat the highway number on a long road trip.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2021 Kia Stinger RWD 3.3L at $2,900. This is based on driving 15,000 miles per year and using national average fuel prices. If you drive significantly more than 15,000 miles annually, or if fuel prices are higher in your area, your actual fuel costs will be higher. If you drive less or source cheaper fuel, you could spend less than the estimated $2,900.

This figure provides a benchmark for comparing the Stinger’s running costs to other vehicles, but it’s an estimate, and individual experiences will vary.

Real-world expectations

EPA figures provide a standardized benchmark, but real-world fuel economy often differs. Stinger RWD 3.3L drivers report figures ranging from the high teens to the low twenties in combined driving, with some achieving better than the EPA highway estimate on long trips. Factors such as driving style, traffic conditions, and even tire pressure impact fuel consumption.

The Stinger’s driving mode also plays a role. “Comfort” or “Eco” modes prioritize fuel efficiency, while “Sport” mode unleashes the engine’s full potential, at the expense of economy. If you drive it like a sports car, it will drink fuel like a sports car. Understanding this and adjusting driving habits can help you get the best possible fuel economy.

How it compares

The Stinger’s fuel economy places it within a specific segment of performance-oriented vehicles. A comparable Acura TLX 2.0T manages a slightly better 25 MPG combined, but lacks the Stinger’s power and rear-drive. The BMW 330i, rated at 28 MPG combined, offers a blend of performance and efficiency, but at a higher price. The Genesis G70 2.0T shares a platform with the Stinger and achieves a similar 24 MPG combined, but the turbo four-cylinder offers less power.

If you care about fuel economy, it is important to look at all Kia fuel economy data before making a final decision; consider the STINGER MPG across all years too. The decision hinges on priorities. The Stinger buyer isn’t solely focused on fuel efficiency. They seek a driving experience with a blend of style, performance, and value. They’re willing to accept a slight fuel economy difference to enjoy the Stinger’s character and capabilities.

Tips to maximize efficiency

Avoid aggressive acceleration. The Stinger’s twin-turbo V6 is responsive, but each burst of power consumes extra fuel. Smooth acceleration allows the engine to operate more efficiently, improving your overall MPG.

Maintain proper tire pressure. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressure regularly and inflate them to the recommended levels outlined in the owner’s manual.

Use cruise control on the highway. Maintaining a consistent speed minimizes unnecessary acceleration and deceleration, resulting in improved fuel efficiency. The Stinger’s adaptive cruise control system can enhance efficiency by automatically adjusting speed to maintain a safe following distance.

Reduce unnecessary weight. Carrying extra weight in your vehicle reduces fuel economy, as it requires more energy to accelerate and maintain speed. Remove any unnecessary items from the trunk and passenger compartment to lighten the load.

Consider using the “Eco” or “Comfort” drive modes when performance isn’t important. These modes remap the throttle response and shift points to prioritize fuel efficiency, helping you save gas during everyday driving.
