20 MPG combined isn’t going to win any fuel economy awards, but the 2018 Kia Stinger RWD with its 3.3-liter twin-turbo V6 isn’t about sipping fuel. It’s about stylish grand touring performance. This particular Stinger is for the driver who prioritizes spirited acceleration and a planted rear-wheel-drive experience over outright frugality. They understand that the burble of a V6 comes at a cost, and they’re willing to pay it.

City and highway performance

The Stinger’s EPA estimates break down to 17 MPG in the city and 25 MPG on the highway. The city figure reflects the engine’s appetite for fuel when dealing with stop-and-go traffic and frequent acceleration. The highway number is more respectable, indicating that the Stinger settles into a more efficient cruise when covering long distances. However, lead-footed drivers will likely see their highway MPG dip below the EPA estimate, as the temptation to use the engine’s abundant power is always present. This is not a car for hypermiling; it’s a car built to be enjoyed.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2018 Kia Stinger RWD 3.3L at $2,900. This figure is based on driving 15,000 miles per year and using national average fuel prices. Remember that this is just an estimate; your actual fuel costs will vary depending on your driving habits, the type of fuel you use, and local fuel prices. Aggressive driving and premium fuel (which is recommended but not required) will certainly push that annual cost higher. However, for many Stinger owners, the added cost is a worthwhile trade-off for the performance and driving experience the car delivers.

Real-world expectations

While the EPA estimates provide a benchmark, real-world fuel economy often differs. Stinger owners frequently report numbers slightly below the official figures, particularly in mixed driving conditions. Expect to see averages in the 18-22 MPG range if your driving includes a mix of city streets and highway miles. Drivers who like to put the pedal down should prepare for even lower numbers, as the Stinger’s performance is simply too alluring to resist. Explore all Kia fuel economy data for more information. And make sure that you do diligent research to find STINGER MPG across all years.

How it compares

Compared to other sporty sedans in its class, the 2018 Kia Stinger RWD 3.3L occupies a middle ground in terms of fuel economy. An Audi S5 Sportback, for example, achieves a combined 24 MPG thanks to its turbocharged V6 and more efficient tuning, appealing to a buyer who wants performance with fewer trips to the gas station. The BMW 440i Gran Coupe, with its inline-six, manages around 25 MPG combined. On the other hand, a V8-powered Dodge Charger R/T will deliver significantly lower MPG, often struggling to reach 19 MPG combined, but offers a visceral muscle car experience the Stinger doesn’t quite match. The Acura TLX V6 (discontinued but still found in the used market) offered similar performance but traded some driving excitement for better-than-20 MPG combined.

Tips to maximize efficiency

Resist the urge to constantly bury the throttle. The Stinger’s twin-turbo V6 is addictive, but frequent bursts of acceleration will reduce your fuel economy. Smooth, deliberate inputs will help you save gas without sacrificing all the enjoyment. Use the car’s various driving modes to your advantage. The “Eco” mode dampens throttle response and optimizes transmission settings for efficiency, making it suitable for mundane commutes on surface streets. It won’t turn the Stinger into a Prius, but it can help you squeeze out a few extra miles per gallon.

Maintain your Stinger properly. Regular oil changes with the correct viscosity, properly inflated tires, and timely spark plug replacements all contribute to optimal engine performance and fuel efficiency. Don’t neglect scheduled maintenance, as neglected components can negatively impact MPG but often go unnoticed during typical driving.

Consider your tire choices carefully. Performance tires offer excellent grip, but often come at the expense of rolling resistance, which impacts fuel economy. Choosing tires with a lower rolling resistance rating can help improve MPG slightly without completely compromising the car’s handling capabilities. However, balance this with the car’s mission and purpose; don’t neuter a performance car for marginal MPG gain.

Minimize unnecessary weight in the car. Carrying around extra weight in the trunk or cabin puts additional strain on the engine, reducing fuel economy. Remove any unnecessary items that are adding weight, as a lighter car is always going to be a more efficient car. Take this advice with a grain of salt, a few pounds here and there won’t make a big difference, but it can add up.
