The 2019 Genesis G90 AWD with the 5.0L V8 gets 18 MPG combined. This isn’t a compact sedan, a hybrid, or anything close to an economy car. This is a flagship luxury sedan, dripping in leather, technology, and old-school V8 power, a deliberate choice for those who prioritize a quiet driving experience over pinching pennies at the pump. The G90 buyer understands that effortless power and all-wheel drive come at a price, and fuel efficiency is simply not their main concern. Instead, they’re focused on arriving in comfort and style, without the ubiquity of the German luxury brands.

City and highway performance

The EPA estimates for the 2019 G90 5.0L AWD break down to 15 MPG in the city and 23 MPG on the highway. These figures are indicative of the engine’s nature. In stop-and-go city driving, the large-displacement V8 works harder to move the G90’s substantial weight, leading to lower fuel economy. On the open highway, however, the engine can cruise more efficiently, approaching its peak fuel economy rating. The eight-speed automatic transmission also plays a role, offering smooth shifts and helping to keep the engine in its optimal power band for both performance and efficiency. Keep in mind that aggressive driving will significantly decrease these numbers, while a gentle, steady approach can help you approach the EPA estimates more consistently.

Annual fuel cost

The EPA estimates that the annual fuel cost for the 2019 Genesis G90 AWD 5.0L V8 is $3,200. This figure is based on driving 15,000 miles per year and using national average fuel prices at the time of calculation. Your actual fuel costs will vary depending on your driving habits, the type of fuel you use (premium is recommended for optimal performance), and local fuel prices. Expect to pay more if you frequently drive in heavy traffic, have a lead foot, or live in an area with high gasoline prices.

Real-world expectations

While the EPA provides a standardized estimate, real-world fuel economy often differs. Several factors can influence your MPG, including driving style, terrain, weather conditions, and even tire pressure. G90 owners who prioritize smooth acceleration, anticipate traffic, and maintain their vehicle properly are more likely to achieve fuel economy closer to the EPA estimates. Those who frequently engage in spirited driving or neglect maintenance will likely see lower numbers. Online owner forums and fuel tracking apps can provide a better sense of what other G90 5.0L AWD owners are experiencing in daily driving.

How it compares

In the realm of large, V8-powered luxury sedans with all-wheel drive, the 2019 G90’s fuel economy is generally in line with its competitors, though some offer more efficient alternatives. For instance, the BMW 750i xDrive, with its twin-turbo V8, achieves a similar EPA rating of 17 MPG combined. The Lexus LS 500 AWD offers a slightly better 21 MPG combined, thanks to its smaller, turbocharged V6 engine. The Mercedes-Benz S560 4MATIC, with its V8 engine, is rated at 19 MPG combined, slightly better. The target buyer for the G90 often finds the value to be good, accepting the fuel economy in exchange for the car’s lower price point compared to these European rivals. It’s a conscious trade-off: a bit more spent at the pump for considerable savings on the initial purchase price.

Tips to maximize efficiency

While fuel efficiency might not be the primary concern for G90 5.0L AWD owners, there are still steps to minimize fuel consumption. Avoid aggressive acceleration and braking, as these actions put unnecessary strain on the engine and consume more fuel. Instead, focus on smooth, gradual inputs to maintain momentum and conserve fuel.

Ensure your tires are properly inflated to the recommended pressure. Underinflated tires increase rolling resistance, which lowers fuel economy. Check your tire pressure regularly, especially during changes in temperature, and adjust as needed.

Reduce unnecessary weight in the vehicle. Carrying around extra cargo adds to the vehicle’s load, forcing the engine to work harder and consume more fuel. Consider removing any items you don’t need to carry on a regular basis.

Consider eco-driving modes, if equipped. These modes often adjust the throttle response and shift patterns to prioritize fuel efficiency. While they might slightly reduce performance, driving in eco-mode can help you squeeze a bit more mileage out of each gallon of fuel.

Maintain your vehicle properly. Regular maintenance, such as oil changes, air filter replacements, and spark plug replacements, ensures that your engine is running efficiently. A well-maintained engine operates at peak performance, maximizing fuel economy and extending its lifespan.
