The 2020 Mercedes-Benz GLE350 4matic’s 22 MPG combined rating with its 2.0L turbocharged four-cylinder engine reflects a balance of priorities. This isn’t solely about maximizing fuel savings. It’s about driving a prestigious, comfortable, and technologically advanced mid-size SUV with standard all-wheel drive, and accepting the fuel costs associated with it. GLE350 4matic buyers likely prioritize luxury, capability, and brand appeal over ultimate fuel efficiency.

City and highway performance

EPA estimates project 19 MPG in the city and 26 MPG on the highway. The 19 MPG city rating reflects the demands of stop-and-go traffic and idling, where the smaller 2.0L engine works harder to move the GLE350’s weight. The 26 MPG highway figure is more respectable, showing that the nine-speed automatic transmission can optimize engine RPM at cruising speeds. Your actual mileage will strongly depend on your driving style and the mix of city and highway miles you drive.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2020 GLE350 4matic at $2,650. This is based on 15,000 miles per year and current national average fuel prices. This is only an estimate. If you drive more or less than 15,000 miles annually, or if fuel prices change, your actual fuel cost will vary. It provides a benchmark for budgeting and comparing the GLE350 4matic to other vehicles. Remember to factor in premium fuel costs, as Mercedes-Benz engines typically perform best with it.

Real-world expectations

While the EPA estimates provide a baseline, real-world MPG can change. Driving style, tire pressure, weather, and terrain all influence fuel consumption. Aggressive acceleration and hard braking will lower MPG, as will high speeds. Keeping proper tire inflation and following scheduled maintenance can help with fuel efficiency. Avoid extended idling.

How it compares

The GLE350 4matic isn’t a fuel economy leader in its class. The 2020 Acura MDX with standard all-wheel drive achieves 22 MPG combined, a similar number. Some hybrid options, like the Lexus RX 450h, offer significantly better fuel economy, around 30 MPG combined. However, those buyers often prioritize fuel savings. Within the Mercedes-Benz lineup, the GLE350’s MPG is lower than some other models. The C300 sedan, for example, can achieve around 28 MPG combined. Those seeking better fuel economy within the GLE range might consider a plug-in hybrid option, if available. See the GLE350 MPG across all years on our website.

Tips to maximize efficiency

Use the GLE350’s driving modes. Select “Comfort” or “Eco” mode for everyday driving to improve fuel efficiency by adjusting throttle response and transmission shift points. Avoid “Sport” mode unless you need the performance, as it will impact fuel consumption.

Anticipate traffic flow and maintain a steady speed. Avoid sudden acceleration and hard braking, as these consume more fuel. Smooth and gradual acceleration allows the engine to operate more efficiently, improving your MPG.

Regularly check and maintain proper tire inflation. Underinflated tires increase rolling resistance, which forces the engine to work harder and reduces fuel efficiency. Consult the sticker on your driver’s side doorjamb for the recommended tire pressure.

Minimize use of accessories that place an extra load on the engine, such as air conditioning. While A/C is necessary, especially in hot weather, be mindful of its impact on fuel economy. Using recirculating air can decrease the demand on the compressor for better mileage.

Avoid extended idling. If you’re stopped for more than a minute or two, it’s generally more fuel-efficient to turn off the engine. Modern engines are designed to restart quickly, and idling consumes fuel without moving.
