18 MPG combined. That’s the reality faced when driving the 2022 Genesis G90 AWD with its reliable 5.0L V8. Fuel efficiency isn’t why anyone chooses this flagship sedan. Instead, buyers are seeking opulence, a smooth and powerful driving experience, and a statement of value. They gladly accept the fuel consumption because what they receive in return is a vehicle that rivals, and in some ways surpasses, established European luxury brands at a more accessible price point.

City and highway performance

The EPA estimates the G90 5.0L AWD will achieve 16 MPG in city driving and 23 MPG on the highway. The city figure reflects the engine’s displacement and the car’s weight. Stop-and-go traffic will inevitably take its toll, even with the smooth-shifting eight-speed automatic transmission working to optimize efficiency where possible. On the open road, the G90 fares noticeably better.

The 23 MPG highway rating is achievable when maintaining consistent speeds, but aggressive acceleration or higher speeds will quickly diminish those numbers. The 5.0L V8 delivers effortless power, and is always ready to tap into its reserves, making fuel consumption a direct reflection of driving style.

Annual fuel cost

The EPA estimates an annual fuel cost of $3,200 for the 2022 Genesis G90 5.0L AWD. This figure assumes 15,000 miles driven per year, using national average fuel prices. This is an estimate. Individual spending will vary based on driving habits, local fuel costs, and the percentage of city versus highway miles driven.

Drivers should be prepared for this number, and consider that the higher insurance costs of more expensive vehicles will be incurred as well.

Real-world expectations

While the EPA provides a standardized benchmark, it’s important to have realistic expectations for real-world fuel economy. Owners of the G90 5.0L AWD will likely see figures close to the EPA estimates, but many circumstances could cause deviations. Aggressive driving, frequent short trips, and even cold weather can negatively impact fuel consumption. Conversely, those who primarily drive on the highway and adopt a more conservative driving style may see slightly better results.

How it compares

Compared to its competitors, the G90 5.0L AWD falls in line with other V8-powered luxury sedans. For instance, the BMW 750i xDrive, with its 4.4L V8, carries an EPA estimate of 17 MPG combined. The Mercedes-Benz S580 4MATIC manages roughly 19 MPG combined from its mild-hybrid V8. The Lexus LS 500 AWD, with its turbocharged V6, scores around 21 MPG combined, making it a slightly more efficient option in the segment, but with less power. The Audi A8’s fuel economy numbers is also slightly better, with a combined 22 MPG. Buyers in this segment often cross-shop these vehicles. While fuel economy isn’t the primary concern, it’s still a factor when weighing the overall ownership costs and impact on less gas used.

Tips to maximize efficiency

Gentle acceleration is crucial. The G90’s abundant power can be tempting, but each hard stomp on the accelerator directly translates to increased fuel consumption. Smooth and gradual acceleration will help the engine operate more efficiently, especially in city driving.

Anticipate stops and maintain consistent speeds. By looking ahead and anticipating traffic flow, you can avoid unnecessary braking and acceleration. On the highway, using cruise control to maintain a steady speed will also help optimize fuel efficiency. Check out G90 MPG across all years for more information.

Tire pressure makes a difference. Ensure that your tires are properly inflated to the recommended pressure listed on the driver’s side doorjamb. Underinflated tires create more rolling resistance, which reduces fuel economy.

Minimize idling. Excessive idling wastes fuel, especially in a large-displacement engine like the G90’s 5.0L V8. If you anticipate being stopped for more than a minute, consider turning off the engine if it is safe to do so.

Regular maintenance is key. Adhering to the manufacturer’s recommended maintenance schedule, including oil changes and air filter replacements, will keep the engine running optimally and ensure the best possible fuel efficiency.
