20 MPG combined isn’t a figure that will set the world on fire, especially in 2024, but it’s an honest assessment for the 2022 Genesis G90 AWD with its 3.3L turbocharged six-cylinder engine. This isn’t a vehicle purchased by penny-pinchers; it’s a statement about quiet luxury, a sanctuary of premium materials and effortless power. Those who choose the G90 understand that ultimate comfort and effortless cruising come at a fuel cost, they’re willing to pay that price for the unique experience the car offers.

City and highway performance

The EPA estimates the 2022 Genesis G90 AWD at 17 MPG in the city and 24 MPG on the highway. The city figure, arguably more relevant for the G90’s typical duty cycle of chauffeuring executives and navigating urban landscapes, reflects the engine’s need to overcome the car’s considerable weight in stop-and-go traffic. The 24 MPG highway rating is more palatable, revealing the efficiency of the eight-speed automatic transmission and the engine’s considerable torque that allows relaxed cruising. While not stellar, these figures are realistic for a large, all-wheel-drive luxury sedan prioritizing comfort and refinement over outright fuel efficiency.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2022 Genesis G90 AWD at $2,900. This figure is based on driving 15,000 miles per year, with 45% of those miles driven in the city and 55% on the highway, using national average fuel prices. Consider this a benchmark; your actual fuel costs will vary depending on your driving habits, local fuel prices, and how frequently you exploit the G90’s considerable performance. This annual fuel cost is a key factor for prospective buyers, and can be compared against G90 MPG across all years.

Real-world expectations

While the EPA provides a consistent yardstick for comparison, real-world MPG often deviates. Owners of the 2022 G90 report figures that generally align with the EPA’s estimates, but aggressive driving, frequent short trips in cold weather, and sustained high-speed cruising can easily push fuel economy below the stated numbers. Conversely, careful drivers who prioritize smooth acceleration and anticipate traffic flow may see slightly improved MPG. It’s critical to adopt a realistic expectation and understand that the G90 rewards a measured driving style with relatively improved efficiency.

How it compares

The fuel economy of the 2022 Genesis G90 AWD positions it squarely within its competitive set. The Lexus LS 500 AWD, for example, manages a slightly better 17 MPG city and 25 MPG highway. The BMW 740i xDrive, with its inline-six, boasts 22 MPG combined. The Mercedes-Benz S500 4MATIC, a perennial benchmark, achieves around 21 MPG combined, with slightly better highway numbers. The Audi A8 offers similar figures, depending on the specific engine configuration. For the buyer who places immense value on fuel economy, there are more efficient luxury cars. However, they may come with compromises in features, comfort, or overall performance compared to the G90. Buyers should also compare these figures against all Genesis fuel economy data.

Tips to maximize efficiency

The Genesis G90’s turbocharged engine responds well to smooth acceleration. Avoid abrupt starts and hard braking, as these actions consume excessive fuel. Gently build speed, and anticipate traffic flow to minimize the need for braking. The G90’s smart cruise control system is also adept at maintaining a consistent speed and distance from other vehicles and can improve highway efficiency.

Ensure your G90’s tires are properly inflated. Underinflated tires increase rolling resistance, which reduces fuel economy. Check your tire pressure regularly and inflate them to the manufacturer’s recommended specifications. This small step can make a measurable difference over time.

Minimize idling. While the temptation to keep the climate control running is strong, excessive idling wastes fuel. If you’re stopped for more than a minute, consider turning off the engine, especially during prolonged stops.

Schedule regular maintenance for your G90. A well-maintained engine runs more efficiently. Ensure that your air filter is clean and that your spark plugs are in good condition. Follow the manufacturer’s recommended maintenance schedule to keep your G90 performing at its best.
