17 MPG combined is not a typo. Nor is it an oversight. That figure represents the EPA’s combined fuel economy estimate for the 2021 Mercedes-Benz AMG GT Black Series, a machine whose very reason for existence sits at the opposite end of the spectrum from fuel efficiency. This isn’t a car for grocery runs or daily commutes; it’s a thinly veiled race car for the road, a brutal instrument designed to carve apexes and devour asphalt. Fuel economy is simply not part of the purchasing equation for its target demographic.

City and highway performance

The AMG GT Black Series achieves 15 MPG in the city and 20 MPG on the highway. You won’t see those numbers unless you drive it gently. The hand-built 4.0L twin-turbo V8, producing a monstrous 720 horsepower, is exceptionally sensitive to throttle input. Prod it gingerly, and you might approach those figures. Unleash its fury, as its owner inevitably will, and expect those numbers to plummet. Highway cruising, while theoretically capable of achieving 20 MPG, is often punctuated by bursts of acceleration and downshifts that decimate fuel consumption. This car demands to be driven hard, and its fuel economy reflects that.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2021 Mercedes-Benz AMG GT Black Series at $3,400. This figure is based on driving 15,000 miles per year, with 45% of those miles driven in the city and 55% on the highway, using national average fuel prices. That’s a considerable sum of money, enough to buy another used car. The Black Series buyer is unlikely to flinch at this; they are buying an experience, not just transportation. The cost of fuel is simply factored into the overall cost of ownership, an acceptable expense for the levels of performance on offer.

Real-world expectations

Expecting to match the EPA estimates in real-world driving is optimistic. The AMG GT Black Series exists to deliver an unparalleled driving experience, and that experience involves exploiting its prodigious power. Expect more frequent fill-ups than the official numbers suggest, especially if you regularly track the car, attend performance driving events, or simply succumb to the temptation to fully unleash the V8’s potential. The cost of high-octane fuel will become a familiar sight on your credit card statements.

How it compares

Considering a few competitors offers some context, even if direct comparisons are slightly absurd due to the Black Series’ extreme focus. The Porsche 911 GT3, another track-focused weapon, manages around 15 MPG combined with its naturally aspirated engine. A Ferrari F8 Tributo, with its turbocharged V8, nets about 18 MPG combined. Even the considerably tamer Mercedes-AMG GT C Roadster boasts only slightly better figures, around 18 MPG combined. Understanding AMG MPG across all years shows the overall trend for performance-oriented vehicles within the brand. The Black Series’ lower number underlines its commitment to all-out performance above all else. Someone cross-shopping these vehicles isn’t prioritizing fuel efficiency but rather comparing raw performance data and brand cachet. They might also consider all Mercedes Benz fuel economy data to see other options.

Tips to maximize efficiency

While the AMG GT Black Series isn’t designed for fuel sipping, a few strategies can help minimize consumption, at least marginally. Focus on smooth acceleration and avoid excessively hard braking. The less you engage the turbochargers, the less fuel you’ll burn. Consider it a challenge, can you still enjoy the car’s handling prowess without constantly pushing it to its limits?

Use the car’s drive modes intelligently. The “Comfort” mode, while still potent, will remap the throttle response and shift points to prioritize efficiency over outright performance. It won’t transform it into Prius, but it can make a difference on longer, less spirited drives.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, leading to higher fuel consumption. Consult the sticker on the driver’s side doorjamb for the recommended tire pressure and check it regularly.

Minimize unnecessary weight. Removing any extraneous items from the car can slightly improve fuel economy. Every little bit helps, even if it’s only a marginal improvement.

Resist the urge to constantly demonstrate the car’s acceleration to every passerby. While the temptation is understandable, each full-throttle run translates directly into a higher fuel bill. Save the theatrics for special occasions; your wallet will thank you.
