24 MPG combined is respectable for the 2016 Mercedes-Benz GLE300 d 4matic, a luxury SUV that values refinement, capability, and a premium driving experience over extreme fuel efficiency. It’s diesel-powered, and its buyers understand that diesel benefits, like torque, longevity, and highway cruising range, often mean slightly lower overall fuel economy than some gasoline cars. This isn’t made for extreme mileage seekers; it appeals to buyers wanting a dependable SUV with all-weather confidence.

City and highway performance

The GLE300 d gets an EPA-estimated 22 MPG in the city and 29 MPG on the highway. While the city MPG reflects urban stop-and-go driving, the highway figure shows this SUV’s strengths. The 2.1L four-cylinder diesel engine, with the 7-speed automatic transmission, cruises comfortably at highway speeds, maximizing its efficiency. The 4matic all-wheel-drive system adds security in bad weather, but also impacts fuel use.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2016 Mercedes-Benz GLE300 d 4matic at $2,300. This is based on driving 15,000 miles yearly, using the national average fuel price. Changes to these factors, like driving more miles, higher local fuel prices, or aggressive driving, will change your actual fuel expenses. Understanding this calculation lets buyers relate the figure to their driving and budget.

Real-world expectations

While the EPA provides a standard, real-world fuel economy can vary based on driving style, terrain, and maintenance. Aggressive acceleration, frequent hard braking, and neglecting maintenance can hurt fuel consumption. Cargo and passenger weight, and using accessories like air conditioning and the 4matic all-wheel-drive system, also matter. Expect slightly lower figures than the EPA estimates if you often drive hard or in tough conditions.

How it compares

Among mid-size luxury SUVs of that time, the GLE300 d’s fuel economy is unique. The gasoline-powered BMW X5 sDrive35i, got an EPA combined rating of 21 MPG. The Audi Q7 2.0T, with its turbocharged gasoline engine, achieved a combined rating of 22 MPG. The Lexus RX 350, known for its smooth operation and reliability, offered a similar 22 MPG combined rating. However, these gasoline vehicles often lack the GLE300 d’s diesel torque and highway cruising range.

Tips to maximize efficiency

Maintain proper tire inflation. Inflating your tires to the pressure on the door jamb sticker reduces rolling resistance, boosting MPG.

Anticipate traffic flow. Avoid sudden acceleration and braking by looking ahead and keeping a consistent speed. This smooth driving is good for diesel engines, helping them operate most efficiently.

Keep your vehicle well-maintained. Regular oil changes, air filter replacements, and following the maintenance schedule ensure the engine runs well. Diesel engines especially benefit from regular maintenance. For more on the GLE300 MPG across all years, look at data from previous and later models.

Minimize idling. Avoid long idling, especially when cold. Modern diesels warm up fast, so long idling wastes fuel. Turn off the engine if you wait more than a minute.

Lighten your load. Remove unneeded items from the vehicle to reduce weight. Less weight improves fuel economy.
