The 2023 Genesis G80 AWD, equipped with its 2.5L 4-cylinder engine, gets 25 MPG combined, a figure that reflects a calculated balance of luxury, performance, and all-weather security. This isn’t a hybrid chasing ultimate efficiency, nor is it a brute-force V8 demanding premium fuel without apology. It’s a sedan positioned for buyers who appreciate refinement and confident handling, accepting mid-pack fuel economy as part of the overall package.

City and highway performance

The EPA estimates the G80 AWD 2.5T at 22 MPG in the city and 30 MPG on the highway. That city figure, while not exceptional, is respectable for a vehicle of this size and weight, particularly with all-wheel drive adding mechanical drag. The 30 MPG highway rating is more impressive; the engine is able to cruise efficiently once it’s up to speed. Long road trips will be kinder to your wallet than stop-and-go urban commutes.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 Genesis G80 AWD 2.5T at $2,300. This figure is based on driving 15,000 miles per year and using national average fuel prices. While individual fuel costs will vary based on driving habits and local gas prices, this provides a standardized benchmark for comparing the G80’s fuel consumption to other vehicles. If you regularly exceed 15,000 miles annually or live in an area with higher fuel costs, you can anticipate a higher annual fuel expenditure.

Real-world expectations

Remember that EPA estimates are conducted in controlled conditions and may not perfectly reflect your personal driving experience. Aggressive acceleration, frequent short trips (where the engine spends more time warming up and less time at optimal efficiency), and consistent use of Sport mode will all negatively impact your fuel economy. A gentle driving style, longer trips, and strategic use of the G80’s Eco mode can help you approach or even slightly exceed the EPA’s estimates. Understanding your own driving patterns is key to accurately predicting your fuel costs.

How it compares

Fuel economy is always relative, especially in the luxury sedan segment. The BMW 530i xDrive, also equipped with a 2.0L turbocharged four-cylinder and all-wheel drive, achieves a slightly better 27 MPG combined. The Mercedes-Benz E350 4MATIC, with its own 2.0L turbo engine and AWD, lands in a similar range with 25 MPG combined. However, the Acura TLX SH-AWD with the turbocharged 2.0L achieves around 24 MPG combined, a bit less than the G80. These differences, although seemingly small, can translate into significant savings over the lifespan of the vehicle, and many buyers in this segment are keen to minimize running costs where possible without sacrificing image or features. Comparing G80 MPG across all years is also critical to making an informed purchasing decision.

Tips to maximize efficiency

Keep your tires properly inflated. The G80’s tire pressure monitoring system (TPMS) is a useful tool, but regular manual checks are recommended. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Consult the sticker on your driver’s side doorjamb for the recommended tire pressure.

Use the G80’s Eco drive mode when appropriate. This mode adjusts the engine and transmission mapping to prioritize fuel efficiency over outright performance. While it may slightly reduce throttle response, it can make a noticeable difference in fuel consumption during highway cruising or in moderate city traffic.

Anticipate traffic flow and avoid sudden acceleration and braking. Smooth, gradual driving minimizes fuel waste. Look ahead, maintain a safe following distance, and try to maintain a consistent speed whenever possible. Consider using adaptive cruise control on the highway to maintain a set speed and distance from other vehicles.

Minimize idling. If you’re stopped for more than a minute or two, turn off the engine. Modern engines are designed to restart quickly and efficiently, and excessive idling consumes fuel without moving the vehicle. This is especially important in urban environments.

Regular maintenance is essential. Ensure that your G80’s engine is properly tuned and that all scheduled maintenance is performed according to the manufacturer’s recommendations. Clogged air filters, worn spark plugs, and dirty engine oil can all negatively impact fuel economy. Check all Genesis fuel economy data on our site for detailed information and comparisons.
