25 MPG combined is acceptable for the 2021 Genesis G80 AWD 2.5L. This isn’t a compact commuter car. It’s a mid-size luxury sedan designed to surround its occupants in style and quiet. The G80 buyer prioritizes a smooth ride, a well-appointed interior, and distinctive design over ultimate fuel efficiency. They’re willing to trade some MPGs for the prestige and comfort this car delivers.

City and highway performance

The EPA estimates 22 MPG in the city and 30 MPG on the highway. The city figure reflects stop-and-go traffic, where the engine is constantly accelerating and decelerating. The highway number showcases the benefits of the G80’s eight-speed automatic transmission, which allows the engine to cruise at lower RPMs, maximizing fuel economy at speed. The all-wheel-drive system adds weight and complexity, but it doesn’t significantly impact fuel economy in steady-state highway driving. The G80’s turbocharger needs to work a little harder in the city, decreasing your fuel economy. Drivers with longer commutes will appreciate getting closer to the 30 MPG number.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2021 Genesis G80 AWD 2.5L at $2,300 per year. This figure is based on driving 15,000 miles per year and using national average fuel prices. It’s a useful benchmark for potential buyers to compare the G80’s running costs to other vehicles in its class. Your actual fuel costs will vary depending on your driving habits, the type of roads you drive on, and local fuel prices. If you’re primarily a city driver, expect your cost to exceed this estimate. If you do a lot of highway driving, you may end up spending less. Check to see if premium fuel is needed for your Genesis, since it is a luxury car.

Real-world expectations

While the EPA estimates provide a standardized comparison, real-world fuel economy often differs. Some drivers report figures close to the EPA’s combined MPG of 25, but variations are common. Aggressive driving, frequent short trips, and extreme weather conditions can negatively impact fuel economy. Careful driving, regular maintenance, and optimal tire inflation can help you achieve or exceed the EPA’s estimates. Premium fuel is recommended (but not required) for optimal performance, and using regular fuel may slightly reduce fuel economy. Stay on top of all Genesis fuel economy data.

How it compares

The G80’s fuel economy is competitive within the mid-size luxury sedan segment. The BMW 530i xDrive, for example, is rated at 25 MPG combined, matching the G80. The Mercedes-Benz E350 4MATIC achieves a similar 25 MPG combined rating. The Lexus ES 350, while not offering AWD, achieves a slightly better 26 MPG combined with its V6 engine. These comparisons highlight that the G80 offers similar fuel economy to its main rivals despite its focus on luxury and comfort. The buyer considering this class of car is often balancing fuel efficiency with performance and prestige, and the G80 strikes a reasonable balance. Ultimately, it’s up to each buyer to decide what matters most to them.

Tips to maximize efficiency

Avoid aggressive acceleration and hard braking. The G80’s turbocharged engine responds well to a gentle touch. Smooth, gradual acceleration will help you stay out of the turbo’s boost range, conserving fuel. Anticipating traffic flow and avoiding sudden stops will also improve your fuel economy.

Maintain proper tire inflation. 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 level, which can be found on a sticker inside the driver’s side doorjamb. Proper tire inflation not only improves fuel economy but also extends tire life.

Minimize idling. Idling consumes fuel without moving the car. If you’re stopped for more than a minute, turn off the engine. The G80 comes standard with auto start-stop, which shuts off the engine at stoplights and restarts it automatically when you lift your foot off the brake. Make sure this feature is enabled to maximize fuel savings in city driving.

Use cruise control on the highway. Cruise control helps maintain a constant speed, reducing unnecessary acceleration and deceleration. This can improve fuel economy on long highway trips. Set the cruise control to a reasonable speed and let the car manage the throttle for optimal efficiency.

Keep up with routine maintenance. Regular oil changes, air filter replacements, and tune-ups ensure that the engine is running efficiently. A poorly maintained engine will consume more fuel and produce more emissions. Refer to the owner’s manual for recommended maintenance intervals and follow them diligently.
