21 MPG combined is not the primary reason someone buys a 2019 Mercedes-Benz AMG GT 53 4matic Plus. Performance, style, and the AMG badge are stronger motivators than pure fuel efficiency. It’s the price you pay for a sleek, technologically advanced “four-door coupe” producing over 429 horsepower.

City and highway performance

The AMG GT 53 achieves 19 MPG in the city and 24 MPG on the highway. The relatively small difference between city and highway figures suggests the car’s efficiency is heavily dependent on driving style, and the effectiveness of its automatic start/stop system and nine-speed automatic transmission in urban environments. Quick bursts of acceleration followed by periods of idling will decrease the MPG. On the open road, the smooth-shifting transmission and aerodynamic design help the GT 53 achieve its best numbers, but aggressive driving will always impact fuel consumption. This isn’t a car designed to merely cruise, and its EPA estimates reflect that.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,750 for the 2019 Mercedes-Benz AMG GT 53 4matic Plus. This figure is based on driving 15,000 miles per year and the national average fuel prices. Individual driving habits and changes in fuel costs will significantly impact the actual amount spent. Drivers with a heavier foot or those who primarily drive in stop-and-go traffic will likely exceed this estimate, while those who drive on the highway with a gentle right foot *might* spend less. Those seeking maximum efficieny can review all Mercedes Benz fuel economy data for more frugal models.

Real-world expectations

While the EPA provides a standardized benchmark, real-world fuel economy for the AMG GT 53 can vary considerably. Some owners report seeing slightly better highway figures, closer to 26 or even 27 MPG, in ideal conditions. Spirited driving, can easily drop the combined MPG into the mid-teens. The turbocharged engine with electric motor contributes to efficiency, but ultimately, driving style dictates the final numbers. Consider the 21 MPG combined figure a starting point, influenced by personal driving habits and conditions.

How it compares

The AMG GT 53 faces competition from other performance-oriented luxury vehicles. For example, the Porsche Panamera 4S, with its 2.9L twin-turbo V6, achieves around 21 MPG combined, closely matching the AMG GT 53. The BMW M850i xDrive Gran Coupe, boasting a powerful V8, delivers around 19 MPG combined, a sacrifice for additional power. A more direct competitor, the Audi RS7 with its 4.0L V8, is rated at just 18 MPG Combined. For the buyer considering the AMG GT 53, this comparison is important: it confirms that while fuel economy isn’t a priority in this segment, the AMG GT 53 does not lag significantly behind its rivals.

Tips to maximize efficiency

Use the car’s drive modes. The “Comfort” or “Eco” setting will prioritize fuel efficiency by optimizing throttle response, transmission mapping, and climate control settings. Use these modes for everyday driving where maximum performance isn’t required.

Make good use of the cruise control system, especially on long highway stretches. Maintaining a steady speed minimizes unnecessary acceleration and deceleration, improving fuel economy significantly. Avoid sudden bursts of speed, as they dramatically impact fuel consumption.

Ensure tires are properly inflated. Underinflated tires increase rolling resistance, forcing the engine to work harder and reducing fuel efficiency. Check tire pressures regularly and maintain them at the recommended levels listed on the door jamb sticker.

Minimize idling. Modern engines consume fuel even when stationary. If you anticipate being stopped for more than a minute, turn off the engine. The AMG GT 53’s automatic start/stop system assists with this, but it can be manually activated or deactivated.

The advertised horsepower is often irresistible, but restraint while driving will deliver more smiles per gallon.
