Factors Affecting Real-World Highway Mileage
It’s crucial to understand that the EPA estimates are standardized tests. Your actual highway mileage can and will vary based on several real-world factors.
-
Driving Speed: This is one of the most significant variables. Most vehicles achieve optimal fuel efficiency at moderate highway speeds, typically between 55-65 mph. Exceeding 70 mph will generally decrease MPG. Aerodynamic drag increases exponentially with speed, meaning higher speeds demand significantly more energy (fuel) to overcome resistance.
For some insights into efficient driving, the U.S. Department of Energy’s FuelEconomy.gov website offers excellent tips on how driving habits impact fuel consumption.
-
Terrain and Hills: Driving through hilly or mountainous terrain requires the engine to work harder, especially during ascents. This will naturally lead to lower MPG compared to driving on flat, level roads.
-
Vehicle Load: The more weight your GL-Class is carrying (passengers, luggage, cargo), the more fuel it will consume. A heavier vehicle requires more energy to accelerate and maintain speed.
-
Tire Pressure: Underinflated tires create more rolling resistance, forcing the engine to work harder and burn more fuel. Regularly checking and maintaining proper tire pressure is essential for both safety and fuel efficiency. Your recommended tire pressures can usually be found on a sticker inside the driver’s doorjamb.
-
Weather Conditions: Strong headwinds can significantly impact MPG by increasing aerodynamic drag. Cold weather can also reduce efficiency as the engine takes longer to reach optimal operating temperature, and cold air is denser.
-
Vehicle Maintenance: A well-maintained vehicle runs more efficiently. Ensure your GL-Class adheres to its recommended maintenance schedule. This includes regular oil changes, air filter replacements, and spark plug checks. Clogged air filters, for instance, restrict airflow to the engine, making it burn fuel less efficiently.
-
Use of Accessories: While the impact is usually minor on the highway, excessive use of air conditioning or other power-hungry accessories can slightly decrease MPG.
Maximizing Your GL-Class Highway Mileage
While you can’t change the fundamental engineering of your 2016 GL-Class, there are several proactive steps you can take to help your vehicle achieve the best possible highway mileage.
-
Maintain Optimal Tire Pressure: As mentioned, this is a simple yet highly effective way to improve fuel economy. Aim for the pressure recommended by Mercedes-Benz, usually found on the sticker in the driver’s side doorjamb.
-
Drive Smoothly and Consistently: Avoid aggressive acceleration and hard braking. Gradually increase speed and anticipate traffic flow to maintain a steady pace. On the highway, setting cruise control can help maintain a consistent speed, especially on flat terrain.
-
Reduce Unnecessary Weight: If you’re carrying items in the cargo area that aren’t needed for your trip, consider removing them. Less weight means better fuel economy.
-
Minimize Idling: While less of an issue on the highway compared to city driving, if you find yourself stopped for an extended period, it’s generally more fuel-efficient to turn off the engine.
-
Adhere to Maintenance Schedule: This is critical for overall vehicle health and optimal performance, including fuel efficiency. Regularly service your GL-Class according to the manufacturer’s recommendations. This includes checking and replacing air filters, spark plugs, and ensuring the engine oil is at the correct level and type.
For detailed maintenance schedules specific to your GL-Class, consult your owner’s manual or the official Mercedes-Benz USA owner’s portal.
-
Observe Speed Limits (and Recommended Speeds): While sticking to speed limits is a legal requirement, understanding that fuel efficiency often peaks around 55-60 mph means that driving even slightly faster can noticeably reduce MPG. For maximum efficiency on long stretches, consider if a slightly reduced highway speed is feasible for your journey.
Performance vs. Efficiency: A Luxurious Compromise
The Mercedes-Benz GL-Class is a luxury SUV designed for comfort, space, and capability. It’s not manufactured with the primary goal of being the most fuel-efficient vehicle on the road.
