18 MPG combined is the reality for anyone considering a 2017 Mercedes-Benz AMG GT with the 4.0L V8. However, MPG is likely the last thing on the mind of someone who pays serious money for a hand-built GT coupe or roadster. This isn’t a practical commuter car; it’s a statement, an experience, and a serious performance machine. The fuel economy is simply the price of admission to a very exclusive club.
City and highway performance
The EPA estimates 16 MPG in the city and 22 MPG on the highway. The city figure reflects the GT’s tendency to be driven enthusiastically, with frequent bursts of acceleration and aggressive overtaking. The highway number, while seemingly achievable on a long, steady cruise, is quickly eroded as soon as the driver decides to even slightly tap into the V8’s massive power. Consider the highway rating a best-case scenario achieved under ideal conditions, not a typical result for most owners.
Annual fuel cost
The EPA calculates that the average owner of a 2017 AMG GT will spend approximately $3,200 per year on fuel. This figure is based on driving 15,000 miles annually, using the then-current national average fuel price for premium gasoline (which the AMG GT requires). Someone who uses the GT as a daily driver in stop-and-go traffic will likely exceed this figure, while someone who reserves it for weekend trips and track days might find themselves spending less, though frequent track use won’t improve fuel consumption.
Real-world expectations
Forget the EPA numbers for a moment. What fuel economy to expect in a 2017 AMG GT mostly depends on the driver’s self-control, or lack thereof. If you’re constantly dipping into the throttle to hear the V8’s roar, expect to see numbers considerably lower than the official estimates. Owners have reported averages hovering around 14-15 MPG in mixed driving. Mindful driving on longer trips can yield results closer to the 22 MPG highway rating, but few AMG GT owners are prioritizing fuel savings behind the wheel of their powerful GT. The simple act of knowing all Mercedes Benz fuel economy data won’t change how you drive this car.
How it compares
The AMG GT exists in a world of high-performance sports cars, not hybrid hatchbacks. A Porsche 911 Carrera S (with a dual-clutch transmission) manages around 21 MPG combined, while a Jaguar F-Type R Coupe, another supercharged V8 competitor, earns a similar 18 MPG. An Audi R8 V10 sits around 16 MPG combined. While other options exist, those listed above will be the main competitors for this vehicle. The choice to shop for AMG MPG across all years really boils down to how much one values less gas over pure performance and brand experience.
Tips to maximize efficiency
First, engage the “Comfort” driving mode. While it won’t transform the AMG GT into a Prius, it does soften throttle response and encourages the transmission to upshift earlier, keeping the engine in a more efficient range. Remember though, the aggressive character of the car will still remain present even within its comfort drive modes.
Second, anticipate traffic and avoid unnecessary acceleration and braking. The AMG GT’s powerful brakes can convert kinetic energy into heat quickly. Smooth, consistent driving will not only improve fuel economy but also enhance the overall driving experience.
Third, ensure your tires are properly inflated. Underinflated tires increase rolling resistance, forcing the engine to work harder and burn more fuel. Check your tire pressures regularly and maintain them at the recommended levels. The pressure information is typically found on a sticker inside the driver’s side door.
Fourth, minimize idling. If you’re stopped for more than a minute, turn off the engine. Modern cars are designed to restart quickly and efficiently, and idling for extended periods wastes fuel. This is especially true with a large displacement engine like the AMG GT’s 4.0L V8.
