19 MPG combined won’t win any fuel economy awards, but for the 2017 Genesis G80 AWD with the 3.8L V6, it’s an acceptable compromise. This isn’t a vehicle bought to maximize miles per gallon; it’s a luxury sedan offering considerable comfort, a smooth ride, and all-weather security. The buyer prioritizes these attributes over outright thriftiness and understands there’s a cost associated with the G80’s spacious interior, refined driving experience, and capable all-wheel-drive system.

City and highway performance

The EPA estimates the 2017 G80 AWD 3.8L at 16 MPG in the city and 25 MPG on the highway. That city figure reflects stop-and-go traffic, where the G80’s weight and the demands of the all-wheel-drive system take their toll. The highway number is more respectable, benefiting from the engine’s ability to cruise at lower RPMs in its top gears and the vehicle’s relatively aerodynamic profile. Expect the highway figure to drop if you frequently drive at speeds above 70 mph.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2017 Genesis G80 AWD 3.8L at $2,300. This calculation is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway, using national average fuel prices. Your fuel costs will vary depending on driving habits, location, and fuel prices in your area. For example, someone who does mostly highway driving and lives in a state with lower gas prices will likely spend less than $2,300 annually.

Real-world expectations

While the EPA provides a standardized benchmark, real-world fuel economy often differs. The G80’s eight-speed automatic transmission can contribute to better mileage when driven gently, but aggressive acceleration will quickly diminish fuel efficiency. Many owners report averages slightly below the official EPA figures, around 17-18 MPG in mixed driving. When evaluating the G80’s fuel costs, factor in your typical driving style and conditions, consult resources like FuelEconomyHub.com for G80 MPG across all years to compare owner experiences.

How it compares

The 2017 G80 AWD 3.8L competes directly with other mid-size luxury sedans offering all-wheel drive. The Lexus GS 350 AWD achieves a slightly better 22 MPG combined. The BMW 530i xDrive is rated at 27 MPG combined; however, that’s for the base four-cylinder model, not the more powerful six-cylinder option that provides similar performance to the G80’s V6. The Mercedes-Benz E300 4MATIC is rated at 25 MPG combined. For those considering similar models from the same maker, all Genesis fuel economy data can be examined to see how the G80 compares to the smaller G70 or larger G90. These differences, while seemingly small on paper, can add up to significant savings (or expenses) over the vehicle’s lifespan, influencing some buyers’ decisions. However, consumers often decide that the G80’s lower price point offsets its thirstier engine.

Tips to maximize efficiency

The 2017 G80 AWD 3.8L responds well to gentle driving habits. Avoid aggressive acceleration and hard braking, as these actions significantly reduce fuel economy. Anticipate traffic flow and maintain a steady speed whenever possible.

Ensure your tires are properly inflated. 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 specifications found on the driver’s side doorjamb.

Reduce excess weight in the vehicle. Carrying unnecessary cargo adds to the vehicle’s weight, impacting fuel efficiency. Remove any items you don’t need to lighten the load.

Schedule regular maintenance. A well-maintained engine operates more efficiently. Follow the manufacturer’s recommended service schedule, including oil changes, air filter replacements, and spark plug inspections.

Consider using the G80’s “Eco” driving mode, if equipped. This mode adjusts throttle response and transmission shift points to prioritize fuel efficiency over performance. While it may slightly reduce acceleration, it can help improve your overall MPG, especially in city driving.
