20 MPG combined won’t win any awards, but that’s what owners of the 2019 Genesis G80 AWD with the 3.3L twin-turbo V6 can expect. This isn’t a car for penny-pinchers; it’s a statement about value and performance for those who appreciate a well-engineered luxury sedan without the flash (or price tag) of its European rivals. The G80 buyer prioritizes style, comfort, and a smooth ride over outright fuel efficiency, accepting the mileage as a tradeoff for the responsive power and all-weather confidence delivered by this configuration.

City and highway performance

The 2019 G80 AWD 3.3T gets 17 MPG in the city, a figure that reflects the engine’s need to work harder in stop-and-go traffic. The turbochargers spool up less frequently at steady cruising speed, resulting in 24 MPG on the highway. This split between city and highway consumption is typical for a turbocharged engine in a vehicle of this size and weight. Aggressive driving will push these numbers down further, while a light foot and anticipation of traffic flow can help nudge them upward.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2019 Genesis G80 AWD 3.3T at $2,900. This is based on driving 15,000 miles per year, using the national average fuel price. Remember that fuel prices fluctuate, and your actual mileage may vary depending on your driving habits and conditions. This is a useful figure for comparison, but individual spending will certainly vary. Whether this cost is acceptable or not depends entirely on the buyer’s financial situation and priorities.

Real-world expectations

While EPA estimates provide a good benchmark, real-world fuel economy often differs. Owners report numbers close to the EPA figures with careful driving, but spirited acceleration and frequent short trips can easily lower the average. Consider tracking your own fuel consumption over time to get a better picture of what you can expect in your typical driving environment. The G80’s trip computer is a useful tool for monitoring fuel economy and adjusting driving habits accordingly.

How it compares

Compared to its competitors, the G80’s fuel economy is in the middle of the pack. The BMW 540i xDrive, another AWD competitor with a turbocharged six-cylinder, achieves a slightly better 25 MPG combined. The Mercedes-Benz E450 4MATIC, with its similar engine configuration, also manages a combined 25 MPG. The Lexus GS 350 AWD, with its naturally aspirated V6, posts 22 MPG combined, a bit better than the Genesis. These differences, while seemingly small, can add up over time. Review G80 MPG across all years to fully appreciate the model’s consumption figures. For context on the broader marque, see all Genesis fuel economy data.

Tips to maximize efficiency

Use the G80’s drive modes. The “Eco” mode can dampen throttle response and adjust transmission shift points to prioritize fuel efficiency. While it might slightly reduce the car’s responsiveness, it can make a noticeable difference in MPG, especially during city driving.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, forcing the engine to work harder and burn more fuel. Check your tire pressure regularly and inflate to the recommended levels listed on the sticker inside the driver’s side door jamb.

Avoid unnecessary idling. If you’re stopped for more than a minute, turn off the engine. Modern engines are designed to restart quickly and efficiently, and idling consumes fuel without moving the vehicle.

Practice smooth acceleration and braking. Anticipate traffic flow and avoid sudden bursts of speed or hard braking. Gentle driving habits will not only improve fuel economy but also extend the life of your brakes and tires.

Reduce weight inside the vehicle. Carrying unnecessary cargo adds to the car’s overall weight, reducing fuel efficiency. Remove any items from the trunk or backseat that you don’t need on a regular basis.
