The 2023 Mercedes-Benz AMG GT 53 4matic Plus has an official EPA rating of 21 MPG combined. While no one buys this car primarily for fuel efficiency, it’s a sleek, stylish, high-performance machine draped in luxury. The fuel economy is simply a cost for effortless acceleration and head-turning looks. It’s a consideration, but rarely a deciding factor for most buyers.

City and highway performance

The EPA provides further detail, rating the AMG GT 53 at 19 MPG in the city and 24 MPG on the highway. The city figure reflects urban driving’s frequent stops, where the 3.0L turbocharged inline-six engine and its mild-hybrid system work harder, and the 9-speed automatic transmission shifts gears more often. The highway number is better and shows the engine’s efficiency at a steady cruise. While prioritizing performance, the mild-hybrid system does recover some energy while coasting, which helps raise the highway MPG figure.

Annual fuel cost

The EPA estimates that annual fuel costs for the 2023 Mercedes-Benz AMG GT 53 will be $2,750. This is based on driving 15,000 miles per year, with 55% city and 45% highway driving, and assumes current national average fuel prices. Individual fuel costs will vary based on driving habits, local fuel prices, and the type of fuel used. The AMG GT 53 requires premium fuel, which typically increases the cost.

Real-world expectations

While the EPA provides a standard, real-world fuel economy can differ. More aggressive driving, frequent performance feature use, and consistent use of Sport+ driving modes will result in lower MPG. However, a driver who focuses on smooth acceleration and uses Eco mode might see numbers close to, or even slightly above, the EPA estimates. Most AMG GT 53 owners are unlikely to prioritize fuel savings over enjoying the car’s performance.

How it compares

The AMG GT 53 competes with rivals offering various performance and fuel economy. For example, the Porsche Panamera 4 E-Hybrid gets better fuel economy, especially when using its plug-in hybrid capability, potentially exceeding 50 MPGe. However, the Panamera has a higher initial price. The BMW M850i xDrive Gran Coupe, with its powerful V8, achieves around 17 MPG combined, significantly less than the AMG GT 53. Audi’s RS7 also delivers similar fuel economy, around 18 MPG combined. These comparisons are important because potential buyers are likely cross-shopping various high-performance luxury sedans; understanding the trade-offs between power, prestige, and fuel consumption is often part of that process.

Tips to maximize efficiency

While saving fuel might not be a top priority for the AMG GT 53 owner, there are ways to optimize fuel efficiency without sacrificing too much performance. Avoid accelerating and braking hard because the smoother you drive, the less fuel you’ll consume. The AMG GT 53’s 3.0L engine delivers plenty of power across the rev range, so you rarely need to push it to its limits.

Use the car’s drive mode selector. Eco mode, while not ideal for the full AMG experience, can improve fuel economy during daily commuting; it adjusts throttle response and transmission mapping to prioritize efficiency. Comfort mode also balances performance and economy for general driving.

Make sure your tires are properly inflated. Underinflated tires increase rolling resistance, which reduces fuel mileage. Check your tire pressures regularly and keep them at the levels specified on the driver’s side doorjamb. This is an easy way to make a small but noticeable difference.

Keep the car as light as possible by removing extra weight. Carrying extra cargo in the trunk adds weight to the vehicle, and that requires the engine to work harder and consume more fuel. Remove any items you don’t need regularly to improve efficiency because a lighter car is always more fuel-efficient.

Think about highway speeds when driving. While the AMG GT 53 is designed for high-speed cruising, fuel economy can decrease significantly at speeds above 70 mph. Maintaining a moderate speed on the highway will help you get the best possible MPG. The 9-speed transmission is geared for efficiency at lower speeds.
