19 MPG combined. This isn’t a Prius, and nobody shopping for a 2022 Mercedes-Benz AMG GLE53 4matic Plus expects it to be. It’s a performance SUV, a meticulously engineered Autobahn stormer with luxurious features. Fuel economy is less important than power, handling, and the experience of owning an AMG. This SUV is for those who value exhilarating performance and are willing to pay for it at the dealership and the pump.

City and highway performance

The EPA estimates are 18 MPG in the city and 22 MPG on the highway. The difference isn’t huge, reflecting the turbocharged engine with electric motor. The 3.0L inline-six engine, with its electric auxiliary compressor and turbocharger, delivers strong power. This means drivers don’t need to aggressively push the engine in the city, contributing to better city numbers. On the highway, the fast-shifting 9-speed automatic transmission helps keep the engine at optimum RPM, optimizing power and fuel efficiency to a point.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2022 Mercedes-Benz AMG GLE53 4matic Plus 3.0L 6-cyl at $3,050. This is based on driving 15,000 miles per year and using national average fuel prices. Premium fuel is recommended for this engine, which will increase the real-world cost. The high fuel cost is the trade-off for the GLE53’s power.

Real-world expectations

EPA estimates can vary based on driving habits, traffic, and weather. Drivers who accelerate quickly will likely see numbers below the EPA estimates, especially in the city. Regular use of AMG’s performance modes will impact fuel consumption. Those who prioritize smooth acceleration and consistent highway speeds may achieve figures closer to, or above, the EPA’s highway rating.

How it compares

The AMG GLE53’s fuel economy is what you’d expect for a performance SUV. The BMW X5 M50i, with its V8 engine, delivers around 16 MPG combined, showing the fuel cost of more power. The Porsche Cayenne S manages around 19 MPG combined, similar to the GLE53. The Audi SQ7, with its turbocharged V8, has an EPA combined rating of 17 MPG. Buyers cross-shopping these models are more concerned with performance than fuel savings, making the GLE53’s economy acceptable in this situation. Considering all Mercedes Benz fuel economy data, the AMG GLE53 sits near the bottom of the list, a result of its performance focus. You can further explore AMG MPG across all years on our site.

Tips to maximize efficiency

Avoid constantly using the AMG’s full power. Aggressive acceleration and high-speed cruising will deplete the fuel tank. Drive more gently. Smooth acceleration and anticipating traffic can improve fuel economy, especially in the city.

Use the GLE53’s drive modes. “Comfort” or “Eco” modes change the engine and transmission for fuel efficiency. These modes don’t deliver the same performance as “Sport” or “Sport+,” but they can save fuel during commuting. You’ll notice the MPG gains from these calmer driving modes when not on your favorite roads.

Proper tire inflation is important. Underinflated tires increase rolling resistance, making the engine work harder. Check your tire pressures and keep them at the recommended levels, usually found on a sticker inside the driver’s side doorjamb.

Minimize idling. Modern engines are efficient and idling wastes fuel. You should turn off the engine if you’re stopped for more than a minute or two, that will help save gas. The GLE53 restarts quickly thanks to its mild-hybrid system.

Regular maintenance is critical. A maintained engine operates efficiently. Follow the manufacturer’s service intervals, including oil changes, air filter replacements, and spark plug replacements. Ignoring these can reduce performance and fuel economy.
