22 MPG combined isn’t thrilling, but for the 2022 Mercedes-Benz GLE350 4Matic, it’s a calculated decision. People buy this car for luxury, space, and the Mercedes brand, not just for saving money on gas. It’s a compromise between moving nearly 4,700 pounds of SUV and keeping fuel costs reasonable.

City and highway performance

The EPA estimates 19 MPG in the city and 26 MPG on the highway. City driving involves a lot of stopping and starting, where the GLE350’s weight and acceleration demands reduce fuel economy. The 26 MPG highway rating is better, thanks to the 9-speed automatic transmission that allows the engine to cruise at lower RPMs. These numbers are decent, showing Mercedes balances efficiency with performance.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2022 Mercedes-Benz GLE350 4Matic at $2,650. This is based on driving 15,000 miles per year with a mix of city and highway driving, using a national average fuel price. This is a significant expense, but GLE350 buyers probably expect it when owning a luxury SUV. They’re likely more concerned about the price or optional features.

Real-world expectations

The EPA estimates are a good starting point, but real-world fuel economy can change a lot based on driving style, road conditions, and weather. Driving hard, short trips, and carrying heavy items will decrease fuel economy. Driving carefully and following speed limits can help you get close to, or even beat, the EPA estimates. Colder weather can also lower fuel economy because the engine needs more energy to warm up and run accessories.

How it compares

The GLE350’s fuel economy is competitive for its class, but consider the alternatives. The BMW X5 sDrive40i gets a slightly better 23 MPG combined, which appeals to those who want good driving and efficiency. The Acura MDX with SH-AWD gets 21 MPG combined, making it a competitor for those who want value and reliability. The Lexus RX 350, which is known for comfort, also gets 22 MPG combined. GLE buyers often compare these models, balancing fuel economy with luxury, technology, and brand. See all Mercedes Benz fuel economy data for a broader comparison.

Tips to maximize efficiency

Use the GLE350’s driving modes. “Comfort” or “Eco” modes optimize the powertrain for fuel efficiency by reducing throttle response and shifting gears sooner. Pay attention to the throttle, avoid quick acceleration, and keep a steady speed.

Keep your tires inflated properly. Underinflated tires increase rolling resistance, making the engine work harder and use more fuel. Check tire pressures regularly and inflate them to the recommended levels, which are on a sticker inside the driver’s side doorjamb.

Don’t idle for too long. Idling wastes fuel without going anywhere. If you’ll be waiting for more than a minute, turn off the engine and restart it when you’re ready. This is important in cities where traffic is common.

Reduce weight. Extra weight decreases fuel economy. Remove unnecessary items from the trunk or cargo area, like sports equipment or tools. The less weight the engine moves, the better the fuel economy.

Follow the manufacturer’s maintenance schedule. Regular oil changes, air filter replacements, and other tasks keep the engine running well and can improve fuel economy. A well-maintained engine uses less gas. Learn more about GLE350 MPG across all years.
