20 MPG combined is what you get with a 2022 Genesis G80 AWD 3.5L. This vehicle isn’t bought for its frugality, but for its striking design, luxurious features, and engaging driving. The all-wheel-drive system and strong twin-turbo V6 engine deliver confidence and performance, but they also lead to fuel consumption that is lower than some competitors.

City and highway performance

The EPA estimates the 2022 Genesis G80 AWD 3.5L achieves 17 MPG in the city and 26 MPG on the highway. The difference between city and highway figures shows the nature of the engine. The twin-turbo V6 needs to build boost to deliver its impressive power, meaning that stop-and-go city driving puts a greater strain on fuel use. On the open highway, with consistent speeds and less need for rapid acceleration, the engine can operate more efficiently. An eight-speed automatic transmission helps optimize the engine’s output for both performance and fuel economy thanks to its broad range of ratios.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,900 for the 2022 Genesis G80 AWD 3.5L. This figure is based on driving 15,000 miles per year and using national average fuel prices. Your personal fuel costs will vary depending on your driving habits, the type of driving you do, and the fuel prices in your area. The $2,900 EPA estimate provides a useful benchmark for comparing the G80 to other vehicles and understanding the potential cost of ownership.

Real-world expectations

While the EPA estimates provide a standardized comparison, real-world fuel economy often differs. Owners who prioritize spirited driving or spend a majority of their time in congested urban environments may see fuel economy figures at the lower end of the EPA range or even below it. Drivers who primarily use their G80 for highway cruising at moderate speeds might see numbers closer to, or even slightly exceeding, the EPA’s 26 MPG highway estimate. Careful driving habits and diligent maintenance are key to achieving the best possible fuel economy.

How it compares

Within the mid-size luxury sedan segment, the Genesis G80’s fuel economy positions it amidst comparable vehicles. The BMW 540i xDrive, with its 3.0L turbocharged inline-six and all-wheel drive, achieves an EPA-estimated 25 MPG combined. The Mercedes-Benz E 450 4MATIC sedan, featuring a 3.0L turbocharged inline-six with mild hybrid assistance, gets 24 MPG combined. The Audi A6 55 TFSI quattro, with a similar turbocharged V6, posts 24 MPG combined. For comparison, you can review all Genesis fuel economy data. The G80’s lower MPG might give pause, but its considerably lower price point helps to offset the fuel costs. You can also assess G80 MPG across all years to see historical trends.

Tips to maximize efficiency

The twin-turbo V6 in the Genesis G80 benefits from smooth and gradual acceleration. Avoid hard launches and heavy throttle inputs, especially when the engine is cold. Let the turbos spool up progressively rather than demanding instant power to conserve fuel.

The G80’s driving mode selector offers an “Eco” mode. Using this mode recalibrates the throttle response, transmission shift points, and climate control settings to prioritize fuel efficiency. This is especially effective for routine commuting.

Tire pressure plays an important role in fuel economy. Make sure that your tires are inflated to the recommended pressure specified on the driver’s side doorjamb. Underinflated tires increase rolling resistance, which reduces fuel efficiency.

Regular maintenance, especially timely oil changes and air filter replacements, is critical for optimal fuel economy. A clean air filter ensures the engine breathes freely, and fresh oil reduces friction, both of which improve efficiency.

Minimize the use of accessories like air conditioning, especially at lower speeds. While necessary for comfort in many climates, the A/C compressor places a load on the engine, decreasing fuel economy. Use the auto climate control sparingly.
