When considering the 2017 Mercedes-Benz AMG GLE43 4matic Coupe, the number 20 MPG combined is key. This figure might raise eyebrows, especially in today’s market, but it represents an acceptable trade-off for those who prioritize a strong engine, striking coupe-like design, and the AMG badge over ultimate fuel savings. It’s a statement.

City and highway performance

The EPA estimates for the GLE43 Coupe are 17 MPG in the city and 23 MPG on the highway. These figures reflect the realities of a high-performance engine and a relatively heavy vehicle with standard all-wheel drive. The city number, in particular, illustrates the impact of stop-and-go traffic on a turbocharged 3.0L V6 designed for spirited acceleration. On the open road, the nine-speed automatic transmission helps the GLE43 Coupe achieve slightly better efficiency, allowing for more relaxed cruising and optimized gear selection at higher speeds. But let’s be honest: no one buys an AMG for relaxed cruising.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2017 Mercedes-Benz AMG GLE43 4matic Coupe at $2,900. This calculation is based on driving 15,000 miles per year and using the EPA’s projected national average fuel prices. This figure offers a clear understanding of the potential financial burden associated with fueling this high-performance crossover coupe. While the GLE43 Coupe delivers a thrilling driving experience, prospective buyers should factor this cost into their overall budget.

Real-world expectations

While the EPA provides a standardized benchmark, real-world fuel economy can vary significantly depending on driving style, road conditions, and maintenance practices. Drivers with a heavier foot and those who frequently engage in the GLE43’s Sport or Sport+ driving modes will likely see numbers below the EPA’s estimates. Drivers who prioritize smooth acceleration and consistent highway speeds may experience results closer to, or even slightly exceeding, the rated figures. Keeping tires properly inflated and adhering to the manufacturer’s recommended maintenance schedule can also contribute to improved fuel efficiency. Always check all Mercedes Benz fuel economy data for every vehicle in Benz’s lineup.

How it compares

Competitors in this segment generally offer similar fuel economy. The BMW X6 xDrive35i, for instance, with its 3.0L turbocharged inline-six, delivers EPA-estimated combined fuel economy in the low 20s, making it comparable to the GLE43 Coupe. The Porsche Cayenne S Coupe, while boasting significantly more power, sees its fuel economy dip into the high teens in combined driving. Even the less performance-oriented Audi Q8 posts similar mpg numbers. For those seeking better fuel economy, the hybrid versions of some of these competitors offer improvements, but at a higher price point and with a slightly different driving experience. For example, the Cayenne E-Hybrid dramatically increases the fuel economy, but it’s a different driving experiences. Buyers considering an AMG are typically less concerned with maximizing fuel efficiency and more focused on performance and exclusivity, but it’s insightful to see how AMG MPG across all years stacks up against other luxury performance vehicles.

Tips to maximize efficiency

Resist the urge to constantly exploit the engine’s power. The GLE43 Coupe’s turbocharged V6 is addictive, but frequent hard acceleration will quickly diminish fuel economy. Employing a gentler driving style, particularly during city commutes, can noticeably improve your gas mileage.

Pay attention to tire pressure. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Regularly check and maintain the recommended tire pressure to optimize efficiency. The correct tire pressures are listed on the driver’s side doorjamb.

Make judicious use of the “Comfort” driving mode. While the “Sport” and “Sport+” modes enhance the driving experience, “Comfort” mode optimizes the engine and transmission settings for efficiency, providing a noticeable improvement in fuel economy during normal driving conditions.

Minimize unnecessary weight. Carrying excessive cargo in the GLE43 Coupe adds weight, which reduces fuel economy. Remove any unnecessary items from the vehicle to improve fuel efficiency. Every pound counts with an AMG.
