2023 Mercedes-Benz GLE580 Fuel Economy Analysis

18 MPG combined won’t win any fuel-sipping awards, but it’s the cost for the performance and luxury offered by the 2023 Mercedes-Benz GLE580 4Matic. This isn’t a vehicle designed for hypermilers; it’s engineered for effortless power, quiet comfort, and a commanding presence. Buyers prioritize a driving experience with a turbocharged V8 and luxury features over saving money at the pump, valuing those aspects far more.

City and highway performance

The EPA estimates the GLE580 achieves 16 MPG in the city and 21 MPG on the highway. The city figure reflects stop-and-go driving where the engine’s weight and power require more fuel. On the open road, the advanced 9-speed automatic transmission and the engine’s ability to cruise at lower RPMs help improve efficiency, though the relatively poor aerodynamics of an SUV like this prevent truly amazing highway MPG.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 Mercedes-Benz GLE580 4Matic to be $3,200. This calculation is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway, using national average fuel prices for premium gasoline. It’s a useful benchmark, but your actual fuel costs will vary depending on your driving habits, local fuel prices, and driving conditions.

Real-world expectations

EPA figures are a good starting point, but real-world fuel economy can vary. Drivers who accelerate quickly or tow heavy loads will likely see numbers below the EPA estimates. However, those who primarily drive on the highway at moderate speeds might achieve slightly better fuel economy. The heavy curb weight of the GLE580 plays a role, so minimizing unnecessary cargo and avoiding aggressive driving will affect fuel consumption.

How it compares

The GLE580’s fuel economy is what you’d expect for a powerful, luxury SUV with a V8 engine. A BMW X5 M50i, with its reliable V8, also gets around 16-22 MPG combined. Even the higher-performance Mercedes-AMG GLE63 S posts similar numbers, despite its increased power, since both vehicles face the same physics and use similar drivetrain technology. A Porsche Cayenne S delivers similar MPG too, though offering a sportier drive. These alternatives are viewed as the GLE 580’s direct rivals, and their buyers often cross-shop these other makes and models.

Tips to maximize efficiency

Use the GLE580’s driving modes. Select “Comfort” or “Eco” mode for everyday driving because they optimize throttle response and shift points to prioritize fuel efficiency. Resist the urge to constantly use the full potential of the V8 engine.

Ensure your tires are properly inflated, since underinflated tires increase rolling resistance, which reduces fuel economy. Check your tire pressure regularly and maintain the recommended levels from the vehicle’s owner’s manual or door jamb sticker.

Avoid unnecessary idling. If you’re stopped for more than a minute, consider turning off the engine. Modern engines restart quickly and efficiently, and idling consumes fuel without moving the vehicle. The GLE580 features an auto start/stop function.

Schedule regular maintenance. A well-maintained engine operates more efficiently. Follow the recommended maintenance schedule for oil changes, air filter replacements, and routine servicing to ensure optimal function, minimizing fuel consumption.
