2023 Mercedes-Benz AMG GLE53 Coupe Fuel Economy: What To Expect

The 2023 Mercedes-Benz AMG GLE53 4matic Plus Coupe gets 19 MPG combined. It’s not a fuel-sipping hybrid, nor is it meant to be. Performance, style, and presence are the priorities and they affect efficiency. The GLE53 Coupe is for a buyer who values the AMG performance and unique coupe-SUV styling, and likely has other vehicles. They aren’t choosing this vehicle to save money on gas.

City and highway performance

The GLE53 Coupe’s 17 MPG city and 21 MPG highway ratings reflect its powertrain and aerodynamics. The city rating reflects the energy required to repeatedly accelerate its heavy curb weight, a penalty increased by stop-and-go traffic. The highway figure, while better, is still affected by the coupe’s sloping roofline, which introduces aerodynamic compromises compared to a traditional SUV shape. The 3.0L inline-six cylinder engine, though equipped with a mild-hybrid system, is primarily designed for power, not better gas mileage.

Annual Fuel Cost

The EPA estimates the annual fuel cost for the GLE53 Coupe is $3,050. This is based on driving 15,000 miles per year, with 55% of those miles in the city and 45% on the highway. The calculation also uses the national average fuel price at the time of the estimate, which will fluctuate. Understand that this $3,050 is an estimate. If you drive more aggressively, drive significantly more miles, or live in an area with higher fuel prices, your actual cost will be higher.

Real-World Expectations

While the EPA provides a useful guideline, real-world fuel economy will vary based on driving habits and conditions. Expect to see figures close to the EPA estimates during normal driving, but aggressive acceleration and frequent use of the AMG’s performance features will lower your average MPG. A more relaxed driving style, particularly on the highway, might yield slightly better results than the EPA’s 21 MPG rating.

How it compares

The segment in which the AMG GLE53 resides isn’t known for prioritizing efficient vehicles. Consider the BMW X6 M50i, a direct competitor with a similar focus on performance and style. It delivers an EPA-estimated 16 MPG combined. The Porsche Cayenne Coupe S, another comparable model, achieves around 18 MPG combined. Even the non-AMG GLE450 Coupe, while slightly more fuel-efficient, only manages around 21 MPG combined. Those seeking better efficiency and a luxurious package may explore all Mercedes Benz fuel economy data and consider something like the GLE350, but that sacrifices the AMG’s performance and image. Consider looking at AMG MPG across all years to see if a different model year would better suit your needs. The GLE53 Coupe isn’t class-leading when it comes to efficiency; it prioritizes performance.

Tips to maximize efficiency

Take advantage of the GLE53’s drive modes. Selecting “Comfort” mode softens the throttle response and optimizes the drivetrain for efficiency, helping to minimize fuel consumption during everyday driving.

Be mindful of your right foot. The AMG GLE53 Coupe has immense power, and frequent hard acceleration will drastically reduce fuel economy. Smooth, gradual acceleration will make a noticeable difference.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, which reduces fuel efficiency. Check your tire pressure regularly and inflate to the recommended levels as listed on the driver’s side door jamb.

Minimize unnecessary weight. Carrying excessive cargo adds weight, forcing the engine to work harder and consume more fuel. Remove any unnecessary items from your vehicle to improve gas mileage.
