19 MPG combined is the price of admission for those seeking the unique combination of performance and luxury offered by the 2021 Mercedes-Benz AMG GLE53 4matic Plus. It’s a figure that won’t win it any green awards, but it’s a compromise most buyers are willing to make when prioritizing a hand-built AMG engine, supple leather, and head-turning style. This isn’t just transportation, it’s a statement.

City and highway performance

The GLE53’s EPA estimates break down to 18 MPG in the city and 22 MPG on the highway. While these aren’t stellar figures, they are fairly typical for a performance-oriented SUV with a powerful six-cylinder engine and standard all-wheel drive. The city MPG reflects the stop-and-go driving conditions that demand more power for acceleration, while the highway number benefits from more consistent speeds and the engine operating in a more efficient range. The 9-speed automatic transmission certainly helps optimize fuel economy on the open road. Keep in mind that these figures are estimates, and your actual mileage will vary depending on driving style, traffic conditions, and vehicle maintenance.

Annual fuel cost

According to the EPA, the annual fuel cost for the 2021 Mercedes-Benz AMG GLE53 4matic Plus is $3,050. This figure is based on driving 15,000 miles per year and using national average fuel prices. It’s important to understand that this is merely an estimate, and what you actually spend on fuel could be significantly higher or lower depending on your individual driving habits and fuel prices in your area. If you predominantly drive in the city or have a heavy foot, expect to surpass this figure. Conversely, those who primarily drive on the highway and practice fuel-efficient driving techniques might see a lower annual fuel cost.

Real-world expectations

While the EPA estimates provide a baseline, real-world fuel economy for the AMG GLE53 can vary considerably. Owners frequently report figures slightly below the EPA estimates, especially in mixed driving conditions. The draw of the AMG’s potent engine and the engaging exhaust note often lead to a more spirited driving style, which inevitably impacts fuel consumption. Don’t expect to consistently achieve 22 MPG on the highway unless you actively focus on maximizing fuel efficiency. A more realistic expectation for mixed driving is likely to be in the 16-20 MPG range. Some owners on long highway trips, being gentle with the throttle, have seen figures around 25 MPG, but this is not the norm.

How it compares

Compared to its competitors, the AMG GLE53’s fuel economy puts it roughly in the middle of the pack. For instance, the BMW X5 M50i, with its powerful V8 engine, achieves a combined MPG of 18. The Porsche Cayenne S, another performance-oriented SUV, offers similar fuel economy numbers, around 19 MPG combined, depending on options. The Audi SQ7, with its turbocharged V8, also delivers around 17 MPG combined. A less performance-focused option like the Lexus RX 350 nets substantially higher fuel economy, around 23 MPG combined, but the RX is hardly a competitor for the AMG GLE53’s blend of performance and luxury. For drivers considering all Mercedes Benz fuel economy data, the AMG GLE53 sits noticeably lower down the list than other Mercedes SUVs. The key takeaway is that buyers in this segment are often willing to sacrifice fuel economy for performance and prestige, making fuel costs a secondary consideration, while others look into AMG MPG across all years to inform their decision.

Tips to maximize efficiency

Take advantage of the GLE53’s driving modes. The “Comfort” or “Eco” mode will soften throttle response, optimize shift points, and generally prioritize fuel efficiency over performance. Leaving the GLE53 in “Sport” or “Sport+” mode will deliver the most engaging driving experience, but it will also significantly reduce fuel economy.

Avoid aggressive acceleration and braking. The AMG GLE53’s engine is responsive, but a gentle and progressive driving style will help conserve fuel. Anticipate traffic flow and maintain a steady speed whenever possible to avoid unnecessary braking and acceleration.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, which negatively impacts fuel economy. Check your tire pressures regularly and inflate them to the recommended levels, which can be found on a sticker inside the driver’s side doorjamb. Consider using the recommended summer tires only for the weather they are intended and swap back to all-season tires for the winter to improve your fuel economy.

Reduce unnecessary weight. Carrying excess cargo adds weight to the vehicle, which requires more energy to accelerate and maintain speed. Remove any unnecessary items from the trunk or cargo area to improve fuel efficiency. This is especially important if you frequently use the GLE 53 for hauling items it wasn’t intended to, and it can put stress on your vehicle.

Consider limiting use of the Automatic engine start/stop system to city driving and moderate traffic to avoid constantly restarting the engine in situations where it provides minimal benefit. On slower city streets it will help, but on the highway, the energy spent on restarting it will equal or exceed the fuel savings.
