A combined 23 MPG won’t win any fuel efficiency awards, but in the world of high-performance luxury coupes like the 2020 Mercedes-Benz AMG E53 4matic Plus Coupe, it’s a figure most buyers accept as the price. This isn’t a car purchased for saving gas; it’s about refined power, style, and the AMG driving experience. The E53 Coupe appeals to individuals or couples who prioritize driving pleasure and brand prestige over fuel savings. Efficiency is secondary to the turbocharged and electrically supercharged 3.0L inline-6 engine, which delivers 429 horsepower and an AMG soundtrack.

City and highway performance

The EPA estimates that the E53 Coupe achieves 21 MPG in the city and 28 MPG on the highway. These figures reflect the engine’s character. In urban environments, the stop-and-go driving means the engine relies more on its turbocharger and electric auxiliary compressor, impacting fuel consumption. The 9-speed automatic transmission, while smooth and responsive, can’t entirely address the demands of frequent acceleration. On the open road, however, the E53’s efficiency improves. At steady cruising speeds, the engine operates more efficiently, allowing for respectable highway fuel economy. The 4MATIC+ all-wheel-drive system, while enhancing grip and stability, adds some weight, which slightly impacts overall MPG compared to a rear-wheel-drive equivalent. Most E53 buyers consider the added all-weather capability a worthwhile trade-off. Performance and luxury are important; fuel economy is a secondary consideration.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2020 Mercedes-Benz AMG E53 4matic Plus Coupe is $2,500. This figure is based on driving 15,000 miles per year and using national average fuel prices. Keep in mind that this is just an estimate. Actual fuel costs will vary depending on individual driving habits, local fuel prices, and the type of fuel used. Premium fuel is recommended for the E53 to ensure optimal performance and efficiency, so owners should expect to pay more per gallon than for regular gasoline. While $2,500 per year might seem high compared to more fuel-efficient vehicles, it’s a minor expense for the target buyer of this performance coupe, who is more concerned with the overall ownership experience than the cost of filling the tank.

Real-world expectations

While the EPA estimates provide a baseline, real-world fuel economy for the E53 Coupe can vary depending on driving style and conditions. Drivers who frequently exploit the engine’s power will likely see figures lower than the EPA estimates. Those who prioritize smooth acceleration and consistent speeds can potentially achieve numbers closer to, or slightly exceeding, the EPA ratings. The type of driving also plays a significant role. City driving with frequent stops and starts will generally result in lower fuel economy than predominantly highway driving. And factors such as tire pressure, vehicle maintenance, and even the use of climate control can influence fuel consumption.

How it compares

Compared to other performance coupes in its class, the 2020 AMG E53 Coupe’s fuel economy is competitive, though not class-leading. The BMW M440i xDrive Coupe, for example, achieves around 25 MPG combined, offering slightly better fuel efficiency. The Audi S5 Coupe, is rated at around 24 MPG combined. The Porsche 911 Carrera, while a step up in performance and price, also lands around 21 MPG combined in some configurations. The E53’s blend of performance, luxury, and all-wheel drive sets it apart. While some competitors may offer slightly better fuel economy, they might lack the AMG’s distinctive character or the E-Class’s level of refinement. Buyers in this segment often prioritize these qualities over fuel savings, seeking a well-rounded package that delivers both excitement and everyday usability.

Tips to maximize efficiency

Although fuel economy might not be the primary concern of an E53 owner, there are still steps you can take to optimize fuel consumption without sacrificing driving enjoyment. Start by adopting a smooth and progressive driving style. Avoid harsh acceleration and braking, as these actions can significantly increase fuel consumption. The E53’s responsive engine and well-tuned suspension make it easy to maintain momentum, reducing the need for sudden bursts of power.

Regular maintenance is also critical for maintaining optimal fuel efficiency. Ensure that your tires are properly inflated to the recommended pressure, as underinflated tires create more rolling resistance and increase fuel consumption. Keep your engine properly tuned, and change your air filter regularly to ensure optimal airflow.

Use the E53’s driving modes. The “Comfort” mode prioritizes efficiency by optimizing the engine and transmission settings for relaxed cruising. This can be useful during highway driving or in congested city traffic. While it reduces the car’s outright performance, it also noticeably improves fuel economy.

Minimize unnecessary weight in the vehicle. Removing any extra items from the trunk or rear seats can reduce the overall weight of the car, leading to improved fuel efficiency. While the effect may be subtle, every little bit helps. Consider limiting your use of the car’s performance features. While the E53 is fun to drive, constantly engaging Sport or Sport+ mode and pushing the engine to its limits will inevitably impact fuel economy.
