19 MPG combined isn’t going to win any fuel efficiency awards, but for the 2019 Mercedes-Benz AMG GLE43 4matic, it’s arguably beside the point. This isn’t a vehicle for hypermilers; it’s a performance-oriented SUV draped in luxury, appealing to buyers who prioritize driving experience and brand prestige over ultimate fuel savings. They want the growl of the AMG-tuned engine, the responsive handling, and the cachet of the three-pointed star. Fuel economy is a secondary consideration, a necessary evil accepted in exchange for the GLE 43’s blend of sport and utility.

City and highway performance

The GLE 43’s fuel economy breaks down to 17 MPG in the city and 22 MPG on the highway, according to EPA estimates. The city figure reflects the demands of stop-and-go traffic, with frequent acceleration and braking taking a toll. The turbocharger spools up more often, the nine-speed automatic shifts more aggressively, and the engine works harder. The highway figure is more palatable, as the GLE 43 settles into a more relaxed cruise. At a steady 70 MPH, the engine isn’t stressed, and the fuel consumption improves. However, aggressive passing maneuvers or sustained high-speed driving will quickly reduce those gains.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2019 Mercedes-Benz AMG GLE43 4matic at $3,050. This figure is based on driving 15,000 miles per year, with a mix of city and highway driving, and assumes national average fuel prices. Of course, this is just an estimate. Individual fuel costs will vary depending on driving habits, location, and local fuel prices. Drivers who primarily drive in the city or those with a lead foot will likely exceed this estimate, while those who primarily drive on the highway and practice fuel-efficient driving techniques may spend less.

Real-world expectations

While the EPA provides a standardized benchmark, real-world fuel economy often deviates. The AMG GLE43’s turbocharger is particularly sensitive to throttle input. Drive it hard, and fuel economy plummets. Drive it gently, and you might approach the EPA estimates. The vehicle’s weight also plays a role. At over 4,800 pounds, the GLE 43 requires more energy to accelerate and maintain speed than a lighter vehicle. Expect the on-board MPG readout to fluctuate considerably based on driving style and conditions. Some owners see slightly below the EPA combined figure in mixed driving.

How it compares

Compared to its competitors, the 2019 AMG GLE43’s fuel economy is fairly typical for a performance SUV in its class. The BMW X5 xDrive50i, with its larger V8 engine, achieves around 17 MPG combined. The Audi SQ5, a direct competitor with a similar turbocharged V6, also hovers around 19 MPG combined. Even the Porsche Cayenne S, another performance-oriented SUV, lands in the same ballpark, with an EPA rating of around 20 MPG combined. For buyers in this segment, fuel efficiency is often secondary to power and prestige, meaning that relatively similar MPG numbers are acceptable for all competing vehicles. If you are looking for all Mercedes Benz fuel economy data or AMG MPG across all years, there are other models to consider.

Tips to maximize efficiency

While the AMG GLE43 isn’t designed for ultimate fuel efficiency, there are strategies to improve mileage. Gentle acceleration is key. Avoid sudden bursts of speed and allow the turbocharger to spool up gradually. This will reduce fuel consumption during the most demanding phases of driving.

Anticipate traffic flow to minimize braking. Each time you brake, you’re converting kinetic energy into heat, wasting fuel in the process. By looking ahead and anticipating slowdowns, you can coast more often and reduce the need to brake aggressively, which conserves fuel.

Ensure proper tire inflation. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressures regularly and inflate them to the recommended levels, which are typically found on a sticker inside the driver’s side doorjamb.

Avoid unnecessary idling. When stationary for more than a minute or two, turn off the engine. Idling consumes fuel without covering any distance. This is especially important in urban environments with frequent traffic stops. Also, avoid using the remote start to pre-heat or pre-cool the car unless absolutely necessary.
