The 2022 Mercedes-Benz AMG E53 4Matic+ Convertible gets an EPA-estimated 22 MPG combined. This isn’t a class leader in fuel efficiency, nor is it designed to be. The E53 Convertible’s specific goal is open-air performance and luxury for drivers who value thrills and style more than ultimate economy. Buyers likely aren’t comparing this car to a Prius, and Mercedes-Benz understands this. It’s a weekend escape car, not a commuter, so fuel consumption reflects that.

City and highway performance

EPA estimates break down to 20 MPG in the city and 27 MPG on the highway. The city number reflects typical stop-and-go traffic, where the E53’s 3.0-liter turbocharged inline-six engine constantly changes its power. The highway number is better, as the car can cruise steadily, allowing the mild-hybrid system to add to efficiency. This car performs best on long, open roads, where you can enjoy its power with sunshine and fresh air. The 9-speed automatic transmission clearly favors performance, quickly downshifting to access the engine’s powerful midrange.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2022 Mercedes-Benz AMG E53 4Matic+ Convertible at $2,650. This number assumes 15,000 miles per year and national average fuel prices. It’s useful for comparing fuel costs across vehicles, assuming your driving matches the EPA test cycle. Drivers who mostly drive in cities or accelerate quickly might see higher annual costs, while owners who drive more on highways or drive more carefully may see lower costs.

Real-world expectations

EPA estimates are a helpful starting point, but your actual MPG will vary with driving style, road conditions, and maintenance. Expect numbers near the EPA estimates. Quick acceleration, frequent hard braking, and idling will hurt your MPG. However, smoother driving and consistent maintenance offer a better chance of reaching the official numbers. Watch the car’s fuel consumption data in the instrument cluster to better understand your driving habits and their effect on fuel efficiency. Owners can track AMG MPG across all years to see MPG variation.

How it compares

The AMG E53 Convertible’s fuel economy is predictably average compared to competitors. The BMW M440i Convertible, for example, gets around 25 MPG combined, offering slightly better fuel efficiency but a different driving style. The Audi S5 Cabriolet achieves around 24 MPG combined. These MPG differences matter to buyers focused on fuel costs who may sacrifice some performance for better economy. However, the E53 buyer often values the AMG brand and performance, accepting the fuel economy trade-off. Buyers interested in lower running cost across the Mercedes Benz lineup, it’s worth taking a look at all Mercedes Benz fuel economy data.

Tips to maximize efficiency

Strategically use the car’s driving modes. “Comfort” mode optimizes the engine and transmission for efficiency, while “Sport” and “Sport+” modes prioritize performance. Selecting “Comfort” during daily driving can notably improve fuel economy.

Check your tire pressure regularly. Underinflated tires increase rolling resistance, making the engine work harder and use more fuel. Keeping tires properly inflated to the recommended pressure on the door jamb sticker improves fuel economy and enhances handling and tire life.

Reduce unnecessary weight. Remove extra items from the trunk and passenger area. Extra weight adds to the vehicle’s load and reduces fuel efficiency.

Anticipate traffic and avoid aggressive driving. Smooth acceleration and gentle braking use less fuel than hard starts and stops. Look ahead, anticipate traffic signals, and maintain a consistent speed when possible.

The E53 has a mild hybrid system that boosts power and enables engine-off coasting. Lift off the accelerator slightly when approaching a stop or coasting downhill, allowing the system to recoup energy and shut off the engine when appropriate.
