23 MPG combined isn’t the most important figure for the 2020 Mercedes-Benz AMG E53 4matic Plus Convertible. Buyers probably aren’t prioritizing ultimate fuel efficiency when shopping for high-performance convertibles, but understanding its consumption is important for anyone considering this open-top experience with a potent 3.0L six-cylinder engine.

City and highway performance

The EPA estimates this AMG E53 variant achieves 20 MPG in the city and 26 MPG on the highway. This difference reflects the engine’s character: refined and responsive around town, truly coming alive on open roads. The nine-speed automatic transmission plays a key role, keeping the engine in its sweet spot for both brisk acceleration and relaxed cruising. While city driving invariably dips into the lower end of the gas mileage range, disciplined highway travel can approach, or even slightly exceed, the EPA’s 26 MPG estimate. As with any performance car, aggressive driving habits will drastically reduce these numbers.

Annual fuel cost

The EPA calculates the annual fuel cost for the 2020 Mercedes-Benz AMG E53 4matic Plus Convertible at exactly $2,500. This figure is based on driving 15,000 miles per year, using the national average price of gasoline when the vehicle was originally rated. Individual fuel costs will vary based on local gas prices, driving style, and the percentage of city versus highway miles driven. While some owners will inevitably spend more, and others less, $2,500 is a reasonable baseline for budgeting purposes.

Real-world expectations

The official EPA figures provide a benchmark, but in reality, expect some variation. Owners who frequently exploit the engine’s performance capabilities, enjoying spirited acceleration and aggressive passing, will likely see fuel economy dip below the stated numbers. Conversely, drivers focusing on smooth, consistent throttle inputs and maximizing highway miles can achieve results closer to the EPA estimates. The AMG E53’s performance-oriented setup, including its AMG-tuned suspension and performance tires, can increase rolling resistance, impacting fuel economy. Those investing in this car for appearance may not take the annual costs into consideration.

How it compares

Compared to other high-performance convertibles, the AMG E53’s fuel economy is in a reasonable range. The BMW M4 Convertible, for example, has an EPA rating of 18 city and 25 highway. Stepping up further in performance, the Porsche 911 Carrera S Cabriolet, with its more powerful engine, has ratings of 18 city and 24 highway and is more expensive. Buyers looking at the E53 may value performance over efficiency and will be shopping across these makes. For shoppers looking at all Mercedes Benz fuel economy data they may consider other E-Class models to save a bit at the pump.

Tips to maximize efficiency

Take advantage of the AMG E53’s driving modes. “Comfort” mode softens throttle response and optimizes transmission programming for fuel-efficient cruising. “Sport” and “Sport+” modes unleash the engine’s full potential, but also significantly increase fuel consumption. Switching into the more fuel friendly drive modes is key to saving gas.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, leading to reduced fuel economy. Check your tire pressures regularly and inflate them to the manufacturer’s recommended levels, found on the door jamb sticker.

Reduce unnecessary weight. Carrying excessive cargo in the trunk or cabin adds to the vehicle’s overall weight, which negatively impacts fuel efficiency. Remove any items you don’t need regularly.

Avoid aggressive driving habits. Rapid acceleration, hard braking, and frequent lane changes consume more fuel than smooth, deliberate driving. Anticipate traffic flow and maintain a steady speed whenever possible.

Plan your trips strategically. Combining errands into a single trip minimizes cold starts, where the engine operates less efficiently. Consider the traffic and road conditions for your travel and plan the best route. See AMG MPG across all years to compare with other performance options.
