The 2022 Genesis G90 RWD 3.3L 6-cylinder gets 19 MPG combined. This isn’t a compact commuter car chasing every last tenth of a mile per gallon; it’s a full-size luxury sedan prioritizing space, comfort, and a quiet driving experience. The G90 buyer understands this tradeoff, willingly exchanging ultimate fuel efficiency for a premium experience on the road.
City and highway performance
The EPA estimates the G90 RWD earns 17 MPG in the city and 24 MPG on the highway. While these numbers are unlikely to win any awards, they are realistically attainable for most drivers. The city figure reflects the stop-and-go nature of urban driving, where the G90’s weight and displacement affect fuel economy. On the open road, the G90’s smooth-shifting 8-speed automatic settles into a relaxed cruise, allowing the turbocharged 3.3L V6 to become surprisingly efficient at maintaining highway speeds. Drivers should note that aggressive acceleration will significantly impact fuel consumption.
Annual fuel cost
The EPA estimates the annual fuel cost for the 2022 Genesis G90 RWD 3.3L 6-cylinder at $3,050. This figure is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway, using national average fuel prices. Your actual fuel costs may vary depending on your driving habits, fuel prices in your area, and the type of fuel you use. Opting for premium fuel, while sometimes recommended for optimal performance in turbocharged engines, will further increase your annual expenditure.
Real-world expectations
While the EPA provides a standardized framework, real-world fuel economy can differ. Factors such as driving style, traffic conditions, and even weather can influence your MPG. Expect to see figures close to the EPA estimates if you drive gently and spend a significant portion of your time on the highway. However, frequent hard acceleration or consistently driving in heavy city traffic will likely result in fuel economy below the official ratings. Owners reporting their actual MPG to online communities, like those discussing G90 MPG across all years, provide valuable insights into what to expect in various driving conditions.
How it compares
The G90’s fuel economy is similar to other full-size luxury sedans that prioritize power and comfort. For example, the BMW 740i, with its turbocharged 3.0L inline-six, is rated at 22 MPG combined. The Mercedes-Benz S500, featuring a turbocharged 3.0L inline-six with mild hybrid assistance, achieves a slightly better 24 MPG combined. The Lexus LS 500 RWD posts 22 MPG combined. While hybrid versions of some competitors offer significantly improved fuel economy, they also come with a higher price tag. For buyers prioritizing a smooth, powerful, and luxurious driving experience at a competitive price point, the G90 provides good value, even if its fuel economy isn’t class-leading.

Tips to maximize efficiency
Adopt a smooth and gentle driving style. Avoid aggressive acceleration and hard braking, as these habits increase fuel consumption. Anticipate traffic flow and maintain a steady speed whenever possible. The G90 responds well to a relaxed driving approach.
Keep your tires properly inflated. Underinflated tires increase rolling resistance, forcing the engine to work harder and burn more fuel. Check your tire pressure regularly and inflate them to the recommended pressure listed on the doorjamb sticker.
Reduce unnecessary weight. Carrying around excessive cargo in your trunk adds weight to the vehicle, reducing fuel efficiency. Remove any unnecessary items to lighten the load and improve MPG. A cleaner trunk means less fuel burned.
Use cruise control on the highway. Maintaining a consistent speed on the highway can improve fuel economy. Cruise control helps eliminate variations in speed and optimize fuel consumption, especially on long journeys.
Consider using “Smart” drive mode. The G90 features selectable drive modes that tailor the vehicle’s performance characteristics. The “Smart” mode will automatically adjust engine mapping and transmission behavior to optimize fuel efficiency based on your driving style and road conditions.
