19 MPG combined is what you get with the 2018 Mercedes-Benz AMG C63 Coupe. This car isn’t bought for fuel efficiency. It’s bought for the thunderous sound of its hand-built 4.0L V8, its sharp handling, and its impressive presence on the road. Fuel economy is a distant afterthought, a necessary evil tolerated for the joy this car delivers.

City and highway performance

The EPA estimates this AMG C63 Coupe gets 17 MPG in the city and 23 MPG on the highway. This difference reflects the car’s dual nature. Stop-and-go traffic and the temptation to accelerate quickly in the city will reduce fuel economy. On the open road, the engine RPMs are lower, and the aerodynamics help achieve the estimated highway MPG. These figures reflect the car’s character as a powerful machine.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2018 Mercedes-Benz AMG C63 Coupe at $3,050. This is based on driving 15,000 miles per year, with 45% in the city and 55% on the highway, using the national average fuel price at the time of calculation. For a vehicle of this type, the fuel cost is part of the ownership experience. Many owners accept this expense for the performance and prestige of the AMG C63 Coupe.

Real-world expectations

EPA figures are a benchmark, but actual fuel economy varies based on driving style, traffic, and vehicle modifications. Drivers who often accelerate quickly and enjoy track-inspired handling should expect figures below EPA estimates. If the vehicle is mainly used for long highway drives with steady acceleration, results might be slightly better. Driver behavior has a greater impact on fuel consumption than mechanical factors.

How it compares

The AMG C63’s fuel economy is similar to its rivals in the high-performance coupe segment. The BMW M4, prior to its 2021 redesign, is rated at 19 MPG combined. The Audi RS5, with its 2.9-liter turbocharged V6, gets a slightly better 21 MPG combined. The Lexus RC F, with its naturally aspirated 5.0-liter V8, achieves around 19 MPG combined. The AMG C63’s fuel consumption is normal for its performance segment. Buyers are often more interested in horsepower and handling than fuel efficiency. See AMG MPG across all years.

Tips to maximize efficiency

Avoid accelerating quickly at every opportunity. The AMG C63’s engine is powerful, but frequent, aggressive acceleration will drastically reduce fuel economy. Smooth inputs will allow you to enjoy the car’s performance while saving gas.

Use the car’s drive modes. Comfort mode softens the throttle and makes the transmission shift early, prioritizing efficiency. Using Comfort mode during commutes can make a difference.

Make sure your tires are properly inflated. Underinflated tires increase rolling resistance, requiring more energy. Regularly check tire pressure to optimize fuel economy and tire life. See all Mercedes Benz fuel economy data

Reduce extra weight. Carrying cargo in the trunk or back seats adds weight, which reduces fuel efficiency. Remove unnecessary items to lighten the load and improve MPG.

Plan your routes strategically. Avoid congested areas and choose routes with fewer stops to significantly improve fuel economy. Using navigation systems to find efficient routes can save fuel and reduce stress.
