The 2019 Mercedes-Benz AMG GT C Coupe gets 17 MPG combined, so it’s not winning any awards for fuel efficiency. But let’s be honest, nobody shopping for a hand-built, twin-turbo V8-powered exotic coupe is prioritizing trips to the pump. This car is for making a statement, for tearing up backroads, and for experiencing the intoxicating blend of performance and luxury that only AMG can deliver. The fuel bill is simply part of the cost of admission.

City and highway performance

The EPA estimates 15 MPG in the city and 21 MPG on the highway for the AMG GT C Coupe. The city figure reflects stop-and-go traffic, where the powerful 4.0L V8 works harder to accelerate the car’s considerable mass. The highway number is more palatable, but still reflects the engine’s high-performance tuning and the AMG’s aerodynamic profile, optimized for downforce rather than ultimate efficiency. The automatic (AM7) transmission contributes to fuel efficiency as much as possible, given the engine’s output, but this car is built for speed and responsiveness above all else.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2019 Mercedes-Benz AMG GT C Coupe at $3,400. This figure is based on driving 15,000 miles per year and using national average fuel prices for premium gasoline, which the AMG GT C requires. It’s a substantial sum, no doubt. However, prospective buyers are likely more concerned with the car’s six-figure price tag and potential maintenance costs than an extra few hundred dollars in fuel each year. They choose this car for what it *is*, not what it saves them.

Real-world expectations

In the real world, expect to see numbers close to the EPA estimates if you drive conservatively. But, let’s be real, nobody buys an AMG GT C Coupe to drive conservatively. The temptation to unleash the engine’s full potential is simply too strong. Aggressive acceleration, frequent use of the paddle shifters, and spirited driving on winding roads will all lead to lower fuel economy. Expect to see numbers closer to 12-14 MPG in mixed driving if you regularly enjoy the AMG GT C’s capabilities. Check out AMG MPG across all years to explore fuel efficiency across the AMG lineup.

How it compares

It is impossible to ignore other vehicles’ fuel economy. Consider the Porsche 911 Carrera S, a comparable performance coupe, which achieves an EPA-estimated 20 MPG combined. Audi’s R8 V10 Performance gets around 16 MPG combined. The BMW’s M8 coupe, another competitor in this segment, earns about 17 MPG combined. While the AMG GT C is on the lower end of the spectrum, these differences are often negligible for the target buyer who prioritizes performance and driving enjoyment over fuel savings. Buyers should explore all Mercedes Benz fuel economy data for a broader reference.

Tips to maximize efficiency

While the AMG GT C Coupe isn’t exactly known for its fuel efficiency, there are a few things you can do to squeeze a bit more range out of each tank. Avoid rapid acceleration and hard braking. Gradual inputs will help the engine operate more efficiently and reduce fuel consumption.

Use the car’s drive modes strategically. The “Comfort” mode will soften the throttle response and optimize the transmission for fuel efficiency, while the “Sport” and “Sport+” modes will prioritize performance. Consider switching to “Comfort” during highway cruising or in stop-and-go traffic.

Ensure that your tires are properly inflated. Under-inflated tires increase rolling resistance, which can negatively impact fuel economy. Check your tire pressure regularly and inflate them to the recommended levels.

Minimize aerodynamic drag by removing any unnecessary cargo from the car and avoiding the installation of aftermarket accessories that increase drag. While a roof rack might look cool, it can significantly reduce fuel efficiency, especially at higher speeds.
