16 MPG combined. That’s the fuel economy for those who want the visceral thrill and opulent presence of the 2024 Mercedes-Benz AMG GT 63 4matic Plus Coupe. This isn’t a number most prospective buyers will dwell on, because the GT 63 isn’t bought to save gas; it’s acquired for its sledgehammer performance, its hand-built AMG engine, and its undeniable road presence. This is a statement car, a machine that prioritizes raw power and exhilarating dynamics over low fuel consumption. The target demographic are affluent individuals who value performance and exclusivity above all else, and are willing to pay the financial price, both at the dealership and at the pump, to secure it.

City and highway performance

The GT 63’s EPA-estimated 13 MPG in the city reflects the realities of stop-and-go traffic and frequent bursts of acceleration in an environment where the engine rarely settles into an efficient cruising range. The 20 MPG highway estimate is more palatable, showcasing the potential for slightly improved efficiency during longer journeys at a steady speed. However, even on the open road, the temptation to use the twin-turbo V8’s prodigious power is ever-present, likely resulting in fuel economy figures below the EPA’s projections.

Annual fuel cost

The EPA estimates that owners of the 2024 AMG GT 63 Coupe will spend approximately $3,600 on fuel annually. This figure is based on driving 15,000 miles per year, with a mix of city and highway driving, and using the EPA’s MPG estimates alongside national average fuel prices. It’s a substantial sum, no doubt, but a price many are willing to pay for the privilege of driving such a potent machine. This annual fuel cost emphasizes the point: this is not a budget-conscious decision. It’s a trade-off accepted by those who prioritize performance over economy.

Real-world expectations

While the EPA provides a standardized baseline, real-world fuel economy for the AMG GT 63 is likely to vary considerably depending on driving style and conditions. Aggressive acceleration, frequent use of the sport modes, and a bias towards city driving will invariably lead to lower MPG figures. Conversely, a more restrained driving style and a greater emphasis on highway cruising could yield results closer to, or even slightly better than, the EPA’s estimates. However, let’s be honest, few will purchase this vehicle and then try to hypermile it. The character of the GT 63 practically demands spirited driving.

How it compares

Compared to its rivals, the AMG GT 63’s fuel economy is, predictably, in the lower end of the spectrum. The Porsche Panamera Turbo S, with its similar performance credentials, achieves around 17 MPG combined. Even the BMW M8 Competition Coupe, a strong contender in this segment, posts similar combined figures – around 17 MPG. These comparisons highlight that the performance this car offers requires sacrifices. Exploring AMG MPG across all years shows a consistent theme – performance and fuel considerations are often opposing priorities.

Tips to maximize efficiency

While saving gas isn’t the main objective of AMG GT 63 ownership, there are still steps that drivers can take to lessen the impact of its thirst. Avoid unnecessary idling. The engine is most inefficient when stationary, burning fuel without covering distance. Modern engines don’t require prolonged warm-ups, so get moving shortly after starting the car.

Anticipate traffic flow and practice smooth acceleration and braking. Abrupt changes in speed waste fuel. Gentle and progressive throttle inputs will help maintain momentum and reduce the strain on the engine.

Ensure that your tires are properly inflated to the recommended pressure. Underinflated tires increase rolling resistance, which in turn reduces fuel efficiency. Check tire pressures regularly and adjust as needed.

Limit the use of aggressive driving modes and features like launch control unless truly necessary. While these enhance performance, they also significantly increase fuel consumption. Reserve these features for moments when you truly want to experience the car’s full potential.

Consider using the “Comfort” driving mode when cruising on the highway or in less demanding driving situations. This mode optimizes the car’s settings for efficiency, reducing throttle response and shifting earlier to keep the engine in a more economical range.
