The 2024 Mercedes-Benz GLE580 4MATIC gets 17 MPG combined. While it won’t lead in fuel efficiency, understanding this number means understanding what the GLE580 is: a supremely comfortable, technologically advanced, and effortlessly powerful luxury SUV. This isn’t a vehicle for those seeking maximum MPG; it’s for those who prioritize a commanding presence, a sublime driving experience, and the ability to effortlessly cover miles, accepting the fuel cost as part of the experience.

City and highway performance

EPA estimates show 15 MPG in the city and 20 MPG on the highway. The city figure reflects the stop-and-go nature of urban driving, where the GLE580’s weight and the inefficiencies of internal combustion engines affect fuel economy. On the highway, the 9-speed automatic transmission settles into a comfortable cruising gear, allowing the engine to operate at lower RPMs and improve fuel economy, but even on the open road, the GLE580’s appetite for premium fuel is considerable. Expect that 20 MPG figure to decrease if you drive aggressively or encounter significant hills.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2024 Mercedes-Benz GLE580 4MATIC is exactly $3,400. This is based on driving 15,000 miles per year, using a mix of city and highway driving, and assuming the national average fuel price for premium gasoline. It’s a large sum, and one that potential buyers should include in their overall cost of ownership. Remember that this is just an estimate; your actual fuel costs will vary depending on your driving habits, local fuel prices, and the conditions in which you drive.

Real-world expectations

While the EPA figures provide a baseline, real-world fuel economy can vary. Aggressive driving, frequent short trips (where the engine doesn’t reach optimal operating temperature), and carrying heavy loads will all negatively affect your MPG. Conversely, gentle acceleration, consistent highway speeds, and well-maintained tires can help you get closer to the EPA estimates. Drivers often report figures within 1-2 MPG of the EPA’s combined rating, but larger differences are possible.

How it compares

The GLE580 competes with other luxury SUVs. The BMW X5 M60i, with its similarly powerful engine, achieves an EPA-estimated 17 MPG combined, the same as the GLE580. The Land Rover Range Rover Sport P400 gets about 21 MPG combined. The Porsche Cayenne S manages around 19 MPG combined. These figures highlight the trade-offs: performance and luxury often increase fuel consumption. For those prioritizing lower fuel costs, the GLE450, with a turbocharged inline-six, achieves considerably better MPG.

Tips to maximize efficiency

Take advantage of the GLE580’s driving modes. “Comfort” mode will help fuel efficiency by adjusting throttle response and transmission mapping. “Sport” mode unlocks the full potential of the V8, so reserve it for when you need extra performance. Constant hard accelerations will quickly decrease your MPG, so smooth and gradual throttle inputs will make a noticeable difference.

Make sure your tires are properly inflated. Underinflated tires increase rolling resistance, making the engine work harder and consume more fuel. Check your tire pressure regularly, and maintain the recommended pressure listed on the doorjamb sticker. This applies to any car, but if you’re trying to save money on a vehicle that gets 17 MPG, it’s even more critical.

Minimize idling. Letting your engine idle for extended periods wastes fuel, especially with a large V8. If you’re stopped for more than a minute, it’s generally more fuel-efficient to turn off the engine and restart it. The GLE’s automatic start/stop system is designed to help, automatically shutting off the engine at stoplights and restarting it when you lift your foot off the brake.

Plan your routes strategically. Avoiding congested areas and opting for routes with consistent speeds can improve your fuel economy. Use your navigation system to identify potential traffic delays and choose alternative routes when possible. The less stopping and starting you do, the better your average MPG will be.
