14 MPG combined for the 2025 Mercedes-Benz AMG GT 63 PRO 4Matic Plus (coupe) reflects its mission: uncompromising performance and a driving experience that electrifies the senses. This car is not designed to sip fuel. It is engineered to devour asphalt, to assault apexes, and to deliver an auditory symphony from its twin-turbo V8. For its buyers, economy is an afterthought. The GT 63 PRO exists for those who demand the pinnacle of Mercedes-AMG engineering in a sleek, four-door coupe package, where the price of admission, both financial and at the fuel pump, is understood and accepted as part of the privilege.

City and highway performance

The AMG GT 63 PRO registers 12 MPG in city driving, dropping to 19 MPG on the highway. These figures indicate the powerful engine under the hood. The 4.0L 8-cylinder engine, mated to a responsive 9-speed automatic transmission, is built for furious acceleration and relentless power delivery. Around town, the sheer mass and instant torque of the V8, combined with the stop-and-go nature of urban environments, naturally translates to higher fuel consumption. It is always ready to spring. On the highway, the 19 MPG figure is respectable for a vehicle of this power, but sustained high speeds and drivers who exploit the engine’s vast reserves will certainly see that number dip. This car is not about maintaining a steady cruise for maximum efficiency, but rather about the thrill of the open road and the potent rush of an available overtaking maneuver.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2025 Mercedes-Benz AMG GT 63 PRO 4Matic Plus at $4,150. This figure is calculated based on an assumed 15,000 miles driven per year, using national average fuel prices, and factoring in the vehicle’s specific combined MPG. For the individual purchasing a vehicle with an MSRP likely approaching or exceeding a quarter-million dollars, a $4,150 annual fuel bill is a negligible line item. It is simply the cost of feeding a hungry, high-performance engine that delivers an unparalleled driving experience. The buyer of this AMG GT 63 PRO is not scrutinizing this number; they are accustomed to premium expenditures for premium experiences, and fuel is just another part of that equation.

Real-world expectations

In the real world, owners of the AMG GT 63 PRO will likely see actual fuel economy vary. The official EPA numbers represent a controlled test environment. In the hands of an enthusiast driver, which is precisely who buys this car, aggressive throttle inputs, frequent blasts to redline, and spirited driving on twisty roads will push those MPG figures even lower. Conversely, a disciplined long-distance highway cruise might yield slightly better than 19 MPG, but that scenario is an anomaly for this vehicle. The GT 63 PRO encourages dynamic driving, and its fuel economy reflects that constant urge to perform. Buyers expect this, embrace it, and would not have it any other way, understanding that the intoxicating sound and relentless power come at a literal cost. The mission of this car is not frugality; it is exhilaration.

How it compares

When stacked against its closest rivals, the 2025 Mercedes-Benz AMG GT 63 PRO’s 14 MPG combined is right in line with expectations for its performance segment. A direct competitor like the Porsche Panamera Turbo S E-Hybrid offers a combined 23 MPGe (miles per gallon equivalent) thanks to its plug-in hybrid powertrain, but its pure gasoline combined rating stands at 19 MPG, still a few points higher, but with a different powertrain philosophy. The BMW M8 Gran Coupe, another strong contender with a similar V8 focus, manages a combined 17 MPG (15 City/22 Highway). The Audi RS 7, with its own potent V8, typically hovers around 18 MPG combined (15 City/24 Highway). These comparisons reveal that the AMG GT 63 PRO pushes the boundary further into pure, unadulterated performance, making fewer concessions for efficiency. Its buyers are not cross-shopping based on MPGs; they are evaluating driving dynamics, brand prestige, and outright power. The AMG GT 63 PRO makes a strong case for itself in this area, even if it uses more fuel.

Tips to maximize efficiency

While efficiency is not the primary concern for an AMG GT 63 PRO owner, several strategies can help temper its thirst, even if marginally. Maintaining smooth throttle inputs and avoiding excessive bursts of acceleration will make the biggest difference in urban driving, allowing the 9-speed transmission to upshift earlier and keep the engine in lower, more efficient RPM ranges.

Proper tire inflation is always critical for fuel economy, and on a performance car like the GT 63 PRO, it also ensures optimal handling and safety. Regularly checking and adjusting tire pressures to the manufacturer’s recommended settings will minimize rolling resistance, contributing to better fuel figures.

Using the “Comfort” or “Slippery” drive modes, when appropriate, will soften throttle response and shift points, making the vehicle less eager to dip into its full power reserves. This can be beneficial in heavy traffic or during extended highway cruises where maximum performance is not required.

Minimizing unnecessary weight in the trunk or cabin can also slightly improve fuel economy. While a few extra pounds will not drastically alter the consumption of a 4.0L V8, every little bit helps in making the engine work less to propel the vehicle.
