The 2023 Mercedes-Benz AMG GLE63 S 4matic Plus achieves 17 MPG combined. This vehicle isn’t about saving money on gas, it’s about a powerful experience designed with German engineering. Buyers likely want a high-performance SUV that handles family duties and track days. Fuel economy is a trade-off for the 603 horsepower on tap.

City and highway performance

The GLE63 S’s EPA estimates show how differently it performs in different conditions. The city rating of 15 MPG reflects the impact of its weight and engine in stop-and-go traffic. While quick bursts offer immediate power, they increase fuel consumption. The 20 MPG highway rating shows that the GLE63 S can be more efficient when cruising. The nine-speed automatic transmission helps keep the engine efficient at higher speeds; however, the vehicle’s aerodynamics and performance tuning still impact fuel use.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 Mercedes-Benz AMG GLE63 S at $3,400. This is based on 15,000 miles per year, with 55% city and 45% highway driving, using national average fuel prices. Consider this estimate a guideline. Your driving habits, local fuel costs, and how often you accelerate hard will change fuel costs. For many owners, that $3,400 is a normal car expense, consider insurance and maintenance. If you are interested in all Mercedes Benz fuel economy data, there is much more to explore outside of this model.

Real-world expectations

Forget the EPA when driving aggressively. The GLE63 S can drop to single-digit MPG when driven hard. The 4.0-liter V8, with twin turbos in the “hot V,” is responsive, but burns more fuel. Expect numbers around the EPA estimates during normal driving. You’ll likely see slightly lower mileage in the city or with frequent hard acceleration. Consider the highway numbers a best-case scenario for long trips.

How it compares

The BMW X5 M Competition, a direct rival, offers a similar experience at an EPA-estimated 15 MPG combined. The Porsche Cayenne Turbo achieves 17 MPG combined, matching the GLE63 S. The Land Rover Range Rover Sport P530 First Edition with its V8 gets 16 MPG combined. The AMG GLE63 S’s fuel economy is typical for its class. Buyers focus on performance, luxury, and brand appeal, not MPG. Look at AMG MPG across all years to see the evolution of the group’s efficiency.

Tips to maximize efficiency

Engage Comfort mode. The AMG GLE63 S has driving modes that change its performance. Comfort mode softens the throttle and optimizes the transmission for less gas. This reduces excitement, but can improve MPG during commutes.

Avoid accelerating hard. The GLE63 S encourages aggressive driving. Rapid acceleration increases fuel consumption. Smooth throttle inputs improve mileage.

Maintain proper tire inflation. Correctly inflated tires reduce rolling resistance and improve fuel efficiency. Check tire pressures and follow the manufacturer’s recommendation.

Lighten the load. Extra weight decreases fuel economy. Remove unnecessary items from the vehicle.

Plan your routes strategically. Avoid congestion and rush hour if possible. Stop-and-go driving hurts fuel efficiency in the GLE63 S.
