The 2023 Mercedes-Benz GLE350 4matic with its 2.0L turbocharged four-cylinder engine gets 21 MPG combined. This figure represents a compromise, a calculated sacrifice accepted by buyers who prioritize luxury, brand cachet, and a specific suite of features over outright fuel efficiency. GLE350 owners aren’t necessarily hypermilers; they are typically affluent individuals or families who value the Mercedes-Benz experience and all-weather capability without stepping up to the thirstier V6 or AMG variants.

City and highway performance

The EPA estimates suggest 20 MPG in the city and 24 MPG on the highway for this particular GLE350 configuration. The city figure reflects the stop-and-go nature of urban driving, where the 2.0L engine and nine-speed automatic transmission can struggle to maintain optimal efficiency. The highway number is more respectable, as the transmission can settle into higher gears and allow the engine to cruise at lower RPMs. Despite the turbocharger, consistent highway speeds will yield the best fuel economy this vehicle can offer.

Annual fuel cost

According to the EPA, the annual fuel cost for the 2023 Mercedes-Benz GLE350 4matic 2.0L 4-cyl is estimated at $2,750. This figure is based on driving 15,000 miles per year and using national average fuel prices. Actual fuel costs may vary depending on driving habits, location, and prevailing fuel prices. Aggressive driving or consistent use of premium fuel (which is recommended but not strictly required) will inflate that number. Not all Mercedes Benz fuel economy data costs that much.

Real-world expectations

While the EPA estimates provide a baseline, real-world fuel economy can vary considerably. Expect slightly lower numbers in cold weather, as the engine works harder to reach operating temperature. Similarly, frequent short trips will negatively impact fuel efficiency. A lead foot will, of course, penalize mileage. However, gentle acceleration and anticipation of traffic patterns can help achieve numbers closer to the EPA estimates. Drivers who routinely load the GLE350 with passengers and cargo can also expect to see a dip in fuel economy.

How it compares

The GLE350’s fuel economy is fairly typical for its class, but certain competitors offer slightly better figures. The Lexus RX 350h, a hybrid, achieves significantly better fuel economy, rated at 36 MPG combined. Even the BMW X5 xDrive40i, with its larger inline-six engine, manages around 23 MPG combined. While not offering hybrid power, you can view more GLE350 MPG across all years to see any trends. The Volvo XC90 B5, with its mild-hybrid system, achieves around 24 MPG combined. For buyers prioritizing fuel efficiency above all else, these alternatives may be more interesting, but they each offer a different blend of luxury, performance, and driving dynamics. Many Mercedes-Benz buyers are drawn to the brand’s particular blend of performance, style, and technology and are willing to accept the fuel economy compromise.

Tips to maximize efficiency

Take advantage of the GLE350’s driving modes. The “Comfort” mode optimizes fuel efficiency by prioritizing smooth acceleration and earlier gear shifts. While “Sport” mode offers more responsive performance, it also consumes more fuel. Choose “Comfort” for everyday driving to maximize MPG.

Ensure tires are properly inflated. Underinflated tires increase rolling resistance, which reduces fuel efficiency. Check tire pressure regularly and maintain the recommended levels specified on the driver’s side doorjamb. This simple step can make a noticeable difference, particularly on longer journeys.

Minimize idling. Excessive idling wastes fuel and contributes to emissions. If anticipating stopping for more than a minute or two, turn off the engine. Modern vehicles are designed to restart quickly and efficiently, making this a simple way to conserve fuel.

Avoid aggressive driving habits. Rapid acceleration, hard braking, and high speeds all decrease fuel economy. Drive smoothly and maintain a consistent speed whenever possible.
