The 2019 Genesis G80 AWD 5.0L gets 18 MPG combined. This isn’t a number that will win any awards for less gas, but enthusiasts and luxury car buyers who prioritize performance already expect it. This G80 appeals to drivers wanting V8 power, a premium feel, and understated style. Fuel economy isn’t their main concern, it’s a consequence.

City and highway performance

The EPA estimates the 2019 Genesis G80 AWD 5.0L gets 15 MPG in the city and 23 MPG on the highway. This difference reflects the engine’s characteristics. The naturally aspirated 5.0L V8 works harder in stop-and-go conditions, lowering city efficiency. However, on the open road, the eight-speed automatic transmission lets the engine cruise at lower RPMs, improving fuel economy to around 23 MPG. Remember that these figures are from controlled conditions, so real-world traffic, driving style, and weather can change these numbers.

Annual fuel cost

The EPA says the annual fuel cost for the 2019 Genesis G80 AWD 5.0L is $3,200. This is based on driving 15,000 miles per year, using national average fuel prices. Individual fuel costs will vary based on local gas prices and driving habits. Drivers who mainly use the G80 for short trips in heavy traffic can expect an annual fuel bill higher than $3,200. If you want to see G80 MPG across all years you’ll see that the 2019 fuel economy is similar to previous years.

Real-world expectations

While the EPA provides a standard, real-world fuel economy for the 2019 Genesis G80 AWD 5.0L can be different. Drivers who accelerate quickly or speed often will likely see numbers below the official ratings. But those who accelerate smoothly and maintain consistent speeds on the highway might see results closer to or slightly above the EPA estimates. Tire pressure, vehicle maintenance, and even the type of gasoline used can matter.

How it compares

The 2019 Genesis G80 AWD 5.0L isn’t competing for best fuel economy. A more efficient alternative in the luxury sedan class is the Lexus ES 350, which gets 26 MPG combined. However, the ES prioritizes comfort and efficiency over raw power. The BMW 540i xDrive offers comparable performance, netting around 25 MPG combined. This shows that turbocharged engines can sometimes deliver better economy with similar horsepower. A base G80 with the 3.8L V6 engine gives buyers better efficiency, up to around 22 MPG combined, but without the V8’s unique sound. The Mercedes-Benz E450 4MATIC comes in at around 25 MPG combined. Buyers who want the throaty V8 in the G80 are trading lower fuel mileage for a more exciting driving experience.

Tips to maximize efficiency

The 5.0L V8 responds well to consistent throttle inputs. Avoid fast starts and speeding to save fuel. Smooth acceleration and watching traffic can reduce fuel use, especially in city driving.

Make sure your tires have the correct pressure. It’s on a sticker inside the driver’s side door. Underinflated tires increase rolling resistance, making the engine work harder and reducing fuel efficiency.

Regular maintenance is critical. Keep the engine tuned and use the recommended oil to reduce friction and improve performance. Dirty air filters reduce airflow and hurt fuel economy.

Use cruise control on the highway to maintain a consistent speed and prevent speeding. This helps fuel economy during long drives. Keep your speed moderate; speeding wastes gas.

Remove unnecessary weight from the vehicle. Extra cargo adds weight, which hurts fuel consumption. Every pound matters, so lightening the load can offer better mileage. If you want to learn more, browse all Genesis fuel economy data.
