The 2018 Mercedes-Benz AMG GLE43 4matic Coupe gets 19 MPG combined. This number indicates choices were made, acknowledging that style, performance, and status sometimes matter more than ultimate fuel efficiency. The GLE43 Coupe prioritizes a head-turning vehicle with a potent engine for drivers who aren’t overly concerned about the cost of premium fuel. Understanding the GLE43 Coupe means recognizing that efficiency, while considered, isn’t its top priority.

City and highway performance

The EPA estimates the GLE43 Coupe gets 17 MPG in the city and 22 MPG on the highway. These numbers are related to its 3.0-liter turbocharged V6 engine and its 9-speed automatic transmission. The city figure reflects frequent stop-and-go driving, where the engine works harder to accelerate its considerable weight. On the open road, the 22 MPG highway estimate is better, as the 9-speed transmission allows the engine to cruise at lower RPMs. However, even at highway speeds, the vehicle’s aerodynamics, due to its coupe-like design, limit its ability to achieve significantly higher fuel economy.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2018 Mercedes-Benz AMG GLE43 4matic Coupe at $3,050. This figure is based on driving 15,000 miles per year and using national average fuel prices for premium gasoline, which the GLE43 requires. This significant annual cost shows what buyers give up for the vehicle’s performance and image. Anyone considering this vehicle should include this figure in their overall budget, along with insurance, maintenance, and other ownership costs.

Real-world expectations

While the EPA estimates provide a baseline, real-world fuel economy can change a lot. Driving habits, traffic conditions, and even the type of terrain can all affect the MPG you achieve. Aggressive acceleration, frequent hard braking, and prolonged idling will all hurt fuel consumption. Owners who mostly drive in congested urban areas should expect fuel economy closer to, or even below, the 17 MPG city rating.

However, those who mainly drive on the highway, keeping a steady speed, may see figures closer to, or slightly above, the 22 MPG highway estimate. Knowing your own driving patterns is key to setting realistic expectations for fuel economy.

How it compares

The GLE43 Coupe is in a segment of performance-oriented SUVs where fuel economy isn’t always the main concern. The BMW X6 xDrive35i, a direct competitor, gets a similar 20 MPG combined. The Porsche Cayenne S, with its own turbocharged V6, offers slightly better fuel economy at 20 MPG combined. Comparing the GLE43 Coupe to the GLC43 SUV (20 MPG combined) shows how the coupe body style slightly affects fuel efficiency, even within the Mercedes Benz family. Buyers cross-shopping these vehicles need to weigh the differences in style, performance, and price alongside the nuances in fuel consumption. For all Mercedes Benz fuel economy data, you can check a wider range of MPG figures.

Tips to maximize efficiency

While the GLE43 Coupe isn’t designed for ultimate fuel efficiency, there are ways to reduce its thirst. Gentle acceleration is key, avoid abrupt starts and hard braking, as these actions waste fuel. The GLE43’s powerful engine delivers ample performance with moderate throttle inputs, so use this to your advantage.

Tire pressure is important for fuel economy. Make sure your tires are inflated to the recommended pressure, listed on the driver’s side doorjamb. Underinflated tires increase rolling resistance, making the engine work harder and consume more fuel. Regularly check and adjust tire pressure, especially when the temperature changes.

Minimize idling. If you expect to wait for more than a minute, turn off the engine. Modern engines are designed to restart quickly and efficiently. Idling consumes fuel without moving the vehicle, which is especially relevant in urban environments with frequent stops.

Take advantage of the GLE43’s driving modes. Select the “Comfort” or “Eco” mode when maximum performance isn’t needed. These modes typically adjust the engine and transmission mapping to prioritize fuel efficiency. Learn to use the different modes to maximize AMG MPG across all years.

Reduce aerodynamic drag. Remove any unnecessary items from the roof rack or cargo carrier, as these increase wind resistance and reduce fuel economy. Even driving with the windows down at highway speeds can slightly impact fuel consumption, so consider using the climate control system instead.
