16 MPG combined is what you can expect from the 2022 Mercedes-Benz AMG GLE63 S 4matic Plus Coupe. This isn’t a vehicle you buy to save on gas. It’s a statement, a powerful combination of aggressive looks, amazing performance, and a luxurious interior. The buyer who chooses this AMG isn’t thinking about gas station stops; they want adrenaline, exclusivity, and the thrill of a hand-built 4.0L V8.

City and highway performance

The EPA estimates 15 MPG in the city and 19 MPG on the highway. Think of these numbers as a starting point. In city traffic, the AMG’s power goes mostly unused, which means lower fuel economy. On the highway, if you’re careful with the gas pedal, you can get close to 19 MPG. But, if you give in to the urge to use the engine’s power, even for a short time, you’ll quickly lose any fuel savings. The 9-speed automatic transmission is generally smooth and responsive, however, it’s designed for performance, not saving gas. It holds lower gears longer than you might expect in a more economical vehicle, which adds to fuel consumption, even at highway speeds.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2022 Mercedes-Benz AMG GLE63 S Coupe is $3,600. This is based on driving 15,000 miles per year, using the national average price for premium gasoline. Fuel prices change, so this cost can vary. Drivers who mostly drive in the city or drive hard will probably spend more than this, while those who mainly drive on the highway and drive gently might spend a little less. Either way, expect a significant fuel bill.

Real-world expectations

The EPA numbers are good for comparison, but your mileage will probably be different. Hard acceleration, using Sport or Sport+ driving modes a lot, and idling for a long time will all hurt your fuel economy. If you drive more easily, use the Eco mode (if the car has one), and don’t idle as much, you might get closer to the EPA numbers. This vehicle weighs over 5,300 lbs and its powertrain is designed for performance, which is important to remember; it takes a lot of energy to move a vehicle this heavy and powerful, no matter how you drive. Many owners find their mileage is closer to the low end of the range, especially if they enjoy the vehicle’s power.

How it compares

The BMW X6 M, a direct competitor, has an EPA combined rating of 15 MPG, which shows the fuel consumption of high-performance SUVs. Even the Porsche Cayenne Turbo Coupe gets only 17 MPG combined. The Audi RS Q8 also gets 16 MPG combined. These comparisons aren’t about finding a fuel-efficient option; they’re about seeing where the AMG GLE63 S Coupe fits in its class. For buyers in this group, a difference of 1 or 2 MPG is often less important than the performance, style, and brand of each vehicle.

Tips to maximize efficiency

Avoid hard acceleration and braking. The AMG’s power is fun, but gentle use of the pedals saves gas. Anticipate traffic and drive at a steady speed when you can. Accelerating quickly and then braking hard uses a lot of fuel.

Check your tire pressure often. Underinflated tires make the engine work harder and use more fuel. Check your tires at least once a month and make sure they have the correct pressure as shown in the owner’s manual.

Remove extra weight. If you carry extra cargo in the trunk or on the roof, the engine has to work harder, which lowers fuel economy. Remove anything you don’t need every day.

Consider using the ECO driving mode, if equipped. This mode changes the throttle response, transmission shift points, and other settings to prioritize fuel efficiency. It might reduce performance a bit, but it can help save fuel, especially in the city. Also compare all Mercedes Benz fuel economy data to other brands to see how Mercedes stacks up.

Service your engine on schedule according to Mercedes-Benz’s recommendations. Regular maintenance such as oil and air filter changes, and spark plug replacements makes sure the engine runs well and efficiently. It is also worth checking out AMG MPG across all years.
