The 2021 Mercedes-Benz AMG GLE53 4matic Plus Coupe gets 20 MPG combined. It’s not a fuel-efficient vehicle, but an aggressive coupe-SUV that values driving thrills and style above all else. The GLE53 Coupe is for buyers who want AMG performance and a head-turning design. Owners prioritize the AMG-enhanced 3.0L inline-6 and the coupe roofline. They care less about fuel costs than enjoying a high-performance machine.

City and highway performance

The EPA estimates the GLE53 Coupe will achieve 18 MPG in the city and 23 MPG on the highway. These numbers show the compromises of blending SUV practicality with sports car ambitions. City driving with constant stops and starts hurts the MPG, as the engine works harder to move the vehicle’s weight. The highway MPG is better, but still reflects the aerodynamic drag of the coupe roofline and the thirst of a boosted six-cylinder.

Spirited driving will lower these estimates. Exploring the full potential of the AMG powerplant will make those numbers drop.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2021 Mercedes-Benz AMG GLE53 Coupe is $2,900. This is based on driving 15,000 miles per year, with 55% of those miles in the city and 45% on the highway, using the national average fuel price. Premium fuel is recommended, so fuel cost fluctuations will change this estimate. This figure provides a solid benchmark if you are considering buying this vehicle.

For owners covering more or fewer miles per year, the annual investment will vary.

Real-world expectations

The EPA provides a standard, but real-world fuel economy depends on driving style and conditions. Aggressive acceleration, frequent hard braking, and idling will hurt fuel consumption. Hilly terrain, heavier loads, and using air conditioning can lower MPG numbers. Don’t be surprised if your experience differs from the EPA estimates. Observing other GLE53 Coupe owners could help set realistic expectations.

How it compares

The GLE53 Coupe’s fuel economy is average for performance SUVs. The BMW X6 M50i, with its more powerful V8 engine, gets a similar 16 MPG city and 22 MPG highway. The Audi SQ8, with its turbocharged V8, is in the same ballpark, reflecting that these vehicles prioritize power. The Porsche Cayenne Coupe’s base trim offers slightly better fuel economy than the AMG GLE53, but its performance is lower. Understanding these trade-offs is critical to finding the vehicle that best fits your priorities. Access AMG MPG across all years to see the range and historical MPG ratings for the AMG lineup.

Tips to maximize efficiency

The AMG GLE53 Coupe has driving modes. Select “Comfort” or “Eco” to reduce throttle response and shift points, helping the engine operate more efficiently. These modes might reduce the AMG’s aggressive nature, but can improve fuel economy for daily commutes.

Anticipate traffic flow, rather than reacting to it. Smooth throttle inputs will reduce hard acceleration and braking, conserving fuel. This works for all vehicles but is crucial in performance models where quick acceleration is tempting.

Make sure tires are inflated. Low tire pressure increases rolling resistance and reduces fuel economy. Check tire pressures regularly and maintain the levels specified on the door jamb. Remember that the pressure listed on the tire is the *maximum* safe inflation amount.

Avoid idling. If you’re stopped for more than a minute, turn off the engine. Modern engines restart quickly, and the fuel saved from avoiding idling can add up. The GLE53 has start/stop technology that shuts off the engine at traffic signals, so make sure this is enabled.

Regular maintenance is critical. A well-maintained engine operates more efficiently. Follow the recommended service schedule and make sure that air filters, spark plugs, and other components are in good condition. Maintaining functionality in the 3.0L turbo engine and transmission translates to better fuel use.
