The 2023 Mercedes-Benz AMG GLE63 S 4matic Plus Coupe offers high performance, but it comes with an EPA combined fuel economy rating of 17 MPG. Drivers who prioritize fuel efficiency won’t buy this vehicle. It’s for those who want fast acceleration and eye-catching style and understand the compromise: its handcrafted, twin-turbocharged V8 engine won’t conserve fuel like a hybrid.

City and highway performance

The EPA estimates 15 MPG in the city and 19 MPG on the highway. This difference reflects the engine’s characteristics. Stop-and-go city traffic keeps the turbos from operating efficiently. On the open road, keeping consistent speeds with minimal acceleration, the GLE63 S Coupe can extend its fuel a bit.

However, lead-footed driving will quickly lower those numbers, even on extended highway trips. The automatic 9-speed transmission helps highway fuel economy by keeping the engine in its optimal range, but it can only do so much against the available power.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 Mercedes-Benz AMG GLE63 S 4matic Plus Coupe is $3,400. This is based on driving 15,000 miles per year, with 45% in the city and 55% on the highway, using national average fuel prices. Premium fuel is required for optimal performance, raising the cost. This $3,400 serves as a reminder that high-performance vehicles have significant running expenses beyond the purchase price.

Real-world expectations

The EPA figures offer a baseline, but real-world fuel economy varies with driving habits and conditions. Aggressive acceleration, frequent Sport+ mode use, and long idling times all hurt fuel consumption. Gentle acceleration, reading traffic flow, and driving efficiently can help you reach or slightly exceed the EPA estimates.

Let’s be honest: most owners of this vehicle probably aren’t driving gently. They will be enjoying the acceleration and the exhaust note, and paying more at the pump.

How it compares

The BMW X6 M Competition gets about 15 MPG city and 20 MPG highway, showing the fuel consumption realities in this segment. The Porsche Cayenne Turbo Coupe, rated at 15 MPG city and 19 MPG highway, sits in the same performance area. Even “more efficient” rivals like the Range Rover Sport P530 First Edition only achieve around 16 MPG city and 21 MPG highway.

These comparisons show that the AMG GLE63 S Coupe fits within the expected fuel economy range for vehicles with this level of power, luxury, and performance. Check AMG MPG across all years for comparison’s sake.

Tips to maximize efficiency

Outright fuel efficiency might not be the main concern of an AMG GLE63 S Coupe owner, but there are steps to minimize fuel consumption. Use the “Comfort” driving mode for commuting. This mode softens throttle response and optimizes shift points for smoother, more efficient driving. The difference is small, but it adds up.

Tire pressures are important. Properly inflated tires reduce rolling resistance, which improves fuel economy. Check the sticker on the driver’s side doorjamb for the recommended pressure, and check regularly, especially during temperature changes.

Avoid unnecessary idling. Modern engines restart quickly, and prolonged idling wastes fuel. If you’re stopped for more than a minute, turning off the engine is usually more efficient, especially in stop-and-go traffic, or while waiting in parking lots.

Minimize aerodynamic drag. The GLE63 S Coupe has a sleek profile, so removing unnecessary items from the roof rack or cargo area can reduce drag and improve fuel economy, especially at higher speeds.

Finally, think about auditing your driving. It’s easy to accelerate fast and brake hard without realizing it. Consciously focusing on driving smoothly for a week or two can show where you can improve efficiency without losing too much enjoyment.
