24 MPG combined is an acceptable fuel economy figure for the 2023 Mercedes-Benz AMG E53 4matic Plus. This isn’t a basic commuter car; it’s a performance-oriented luxury sedan (or coupe or convertible, depending on your preference) designed to thrill more than to save gas. Its buyers understand this trade-off, prioritizing driving experience and prestige over outright efficiency. The E53 caters to those who want a daily driver that can confidently take on a back road on the weekends, a mission where efficiency is less important than responsiveness and power.

City and highway performance

The EPA estimates of 21 MPG in the city and 29 MPG on the highway show the E53’s dual nature. Stop-and-go city driving, with its constant acceleration and braking, taxes the 3.0L inline-six and its mild-hybrid system. The highway figure, however, demonstrates that when cruising at a steady speed, the E53’s efficient engine and nine-speed automatic transmission can deliver respectable fuel economy. The 29 MPG highway figure is achievable on long road trips when you’re not constantly dipping into the turbocharger’s reserves.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2023 Mercedes-AMG E53 is $2,400. This calculation is based on driving 15,000 miles per year and using the EPA’s projected national average fuel price. This figure provides a benchmark, but your actual fuel expenses will vary depending on your driving habits, local fuel prices, and how often you drive using the E53’s performance capabilities. Driving aggressively will invariably lead to more frequent trips to the gas station and a higher annual fuel bill.

Real-world expectations

While the EPA estimates provide a useful baseline, real-world fuel economy for the AMG E53 will likely fluctuate based on individual driving styles, traffic conditions, and the type of roads driven. Drivers who spend most of their time in heavily congested urban areas might see figures closer to the city estimate, while those with longer commutes on open highways might achieve numbers closer to, or even slightly above, the highway figure. Aggressive driving, characterized by frequent hard acceleration and braking, will negatively impact fuel economy. Conversely, adopting a smoother, more moderate driving style, and using the car’s drive modes well, can help improve efficiency. Don’t be surprised if your average MPG varies significantly from the EPA combined figure, it’s more of a guideline than a guarantee.

How it compares

In the realm of performance-oriented luxury sedans, the AMG E53’s fuel economy is fairly competitive. The BMW M550i xDrive, with its powerful V8 engine, delivers a combined 19 MPG. The Audi S6, also boasting a potent V6, achieves a combined 22 MPG. Even the Porsche Panamera 4S, known for its performance pedigree, comes in around 21 MPG combined. Considering the AMG E53’s performance capabilities, its MPG figures are acceptable for this class of vehicle. For buyers cross-shopping these high-performance trims, fuel economy often takes a backseat to horsepower, handling, and overall driving enjoyment, but finding a balance like the AMG E53 offers is a smart choice. If even this is more than you want, be sure to review all Mercedes Benz fuel economy data to see how its other offerings stack up, and maybe review AMG MPG across all years should you be open to a pre-owned car.

Tips to maximize efficiency

Take advantage of the AMG E53’s driving modes. Selecting “Comfort” or “Eco” mode will change the throttle response, shift points, and other parameters to prioritize fuel efficiency. This can make a noticeable difference, particularly in city driving, without completely sacrificing the car’s performance character. Also, make sure you are obeying all posted speed limits.

Pay attention to tire pressure. Properly inflated tires reduce rolling resistance, improving fuel economy. Check your tire pressure regularly and inflate them to the recommended pressure listed on the door jamb sticker. This simple maintenance task can have a surprising impact on efficiency.

Avoid unnecessary idling. Modern engines are designed to be efficient even at startup, so idling for extended periods is generally wasteful. If you’re stopped for more than a minute, it’s usually more efficient to turn off the engine. This becomes even more critical due to the popularity of stop/start systems. Make sure yours is functional.

Reduce your reliance on hard acceleration and braking. Anticipate traffic flow and maintain a smooth, consistent speed whenever possible. Gradual acceleration and gentle braking not only improve fuel economy but also reduce wear and tear on the car’s components.

Minimize your use of accessories. Air conditioning, heated seats, and other electrical accessories place a load on the engine, which reduces fuel economy. Use these features reasonably, particularly in city driving, when their impact on efficiency is most noticeable.
