21 MPG combined is what you get for serious performance in the 2017 Mercedes-Benz AMG C63. No one buys a C63 expecting Prius-level less gas. This is a car designed to thrill, to deliver explosive acceleration and a symphony of V8 sound. The relatively modest impact on your wallet at the pump is simply a compromise most owners are willing to make for that experience. These buyers prioritize power, handling, and the prestige of the AMG badge far above saving a few dollars at the gas station. They understand the inherent trade-off, and they accept it willingly.

City and highway performance

The EPA estimates the 2017 AMG C63 achieves 18 MPG in the city and 25 MPG on the highway. While these numbers represent ideal conditions in a laboratory setting, they provide a useful benchmark for comparing the car against its rivals. The city figure reflects the stop-and-go nature of urban driving, where the powerful engine and aggressive throttle response inherently lead to increased fuel consumption. The highway figure, while better, is still indicative of the car’s performance-oriented nature; even at cruising speeds, the engine is always ready to unleash its considerable power. The 7-speed automatic transmission, while offering smooth and responsive shifts, is geared for performance rather than ultimate fuel economy.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2017 Mercedes-Benz AMG C63 is $2,750. This figure is based on driving 15,000 miles per year, with a 55/45 split between city and highway driving, and using the national average fuel price. While your actual fuel costs may vary depending on your driving habits and local fuel prices, this number provides a good indication of the ongoing expenses associated with owning a high-performance vehicle like the C63. If you drive less than 15,000 miles annually, or if you live in an area with lower fuel prices, your actual cost could be lower; conversely, aggressive driving or higher local fuel costs will increase it accordingly.

Real-world expectations

While the EPA estimates provide a baseline, real-world fuel economy for the C63 can vary widely based on driver behavior. Those who frequently engage in spirited driving, using the car’s full performance potential, will likely see figures considerably lower than the EPA estimates. Drivers who adopt a more conservative driving style, minimizing hard acceleration and maintaining consistent speeds, may be able to approach the EPA numbers. Factors such as traffic conditions, weather, and even tire pressure can all influence fuel consumption. It’s sensible to expect something in the range of 16-20 MPG combined for most drivers under normal conditions.

How it compares

Compared to its direct competitors, the 2017 AMG C63’s fuel economy is about what you’d expect. The BMW M3, for instance, is rated at 20 MPG combined. The Audi RS5 manages 19 MPG combined. These variations are often secondary to the performance and driving experience offered by each respective model. For the buyer, the subtle differences in MPG figures are less consequential compared to the subjective factors like handling characteristics, engine sound, and overall brand appeal.

Tips to maximize efficiency

Resist the urge to constantly use the engine’s power. The AMG C63 is incredibly responsive, and its intoxicating exhaust note encourages aggressive acceleration. However, easing off the throttle and maintaining a steady speed will significantly improve fuel economy. Use the car’s cruise control on the highway whenever possible.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, which requires the engine to work harder and consume more fuel. Check your tire pressure regularly, using a quality gauge, and inflate them to the recommended levels as indicated on the tire placard.

Limit short trips. Cold starts are particularly fuel-intensive, as the engine requires extra fuel to reach its optimal operating temperature. Combining short errands into a single trip can help reduce fuel consumption.

Consider using a lighter touch. Driving with a “feather foot” can make a surprisingly large difference in fuel economy. Anticipate traffic flow, avoid sudden acceleration and braking, and maintain a smooth, consistent speed. You can research AMG MPG across all years.
