The 2024 Mercedes-Benz GLE350 4matic gets 23 MPG combined, which isn’t exceptional, but fuel economy isn’t the main selling point for this model. Buyers in this segment typically want luxury, brand recognition, and a comfortable driving experience, all of which outweigh the need for great gas mileage. They often accept average gas mileage for the prestige and features the GLE350 offers.

City and highway performance

The EPA estimates for the 2024 GLE350 4matic, which has a 2.0L turbocharged four-cylinder engine and nine-speed automatic transmission, are 20 MPG in the city and 27 MPG on the highway. The city figure reflects the frequent stops and starts of urban driving, where the engine works harder and idles more. The highway number is better, showing how the nine-speed transmission lets the engine run at lower RPMs, improving efficiency.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2024 Mercedes-Benz GLE350 4matic at $2,500. This is based on driving 15,000 miles per year using national average fuel prices. Your actual fuel costs will depend on your driving habits, the type of driving you do, and gas prices in your area. However, this $2,500 figure gives you a benchmark to compare the GLE350’s fuel expenses with similar vehicles. Always check all Mercedes Benz fuel economy data to get a complete picture.

Real-world expectations

EPA estimates provide a standard comparison, but real-world MPG can change a lot. Driving style, traffic, and even tire pressure can affect fuel economy. Fast acceleration, hard braking, and long periods of idling will lower your MPG. Smooth, steady driving and proper tire pressure will help you get closer to the EPA estimates. Expect the fuel economy to decrease if you drive in harsh conditions such as snow or off-road. Be sure to check GLE350 MPG across all years to consider any model year variations.

How it compares

The GLE350 4matic’s fuel economy is average for its class. The BMW X5 sDrive40i, with its inline-six cylinder, gets a slightly better 25 MPG combined. The Acura MDX, especially the base trim, gets about 22 MPG combined. The Lexus RX 350 also gets 25 MPG combined. These differences are important for buyers who are comparing and weighing fuel costs and other things. While numbers are similar for some competitors, buyers in this segment care less about a small 1-2 MPG difference and care more about the overall ownership experience, interior features, technology, and brand image.

Tips to maximize efficiency

Use the GLE350’s driving modes. Select “Eco” mode for everyday driving. It optimizes throttle response, shift points, and climate control to prioritize fuel efficiency over outright performance.

Eco mode may feel slow sometimes, but it can noticeably reduce fuel consumption, especially during city driving.

Check your tire pressure regularly. Underinflated tires increase rolling resistance, making the engine work harder and burn more fuel. Check your tire pressure at least once a month and before long trips. The recommended tire pressure for the GLE350 is usually on a sticker on the driver’s side doorjamb or in the owner’s manual.

Avoid aggressive driving. Rapid acceleration and hard braking waste fuel. Accelerate smoothly and gradually, anticipating stops to avoid braking. Maintain a steady speed on the highway to improve fuel economy. Use cruise control when you can to maintain a steady pace.

Minimize idling. Idling burns fuel without going anywhere. If you expect to stop for more than a minute or two, turn off the engine. Modern cars like the GLE350 restart quickly and efficiently. In the wintertime it might be difficult to turn off the auto-start/stop feature, so be ready to accept a hit on gas mileage.
