The 2020 Mercedes-Benz AMG C63 gets an EPA-estimated 21 MPG combined. Let’s be honest: nobody buys an AMG C63 for its fuel efficiency. This is a snarling, tire-shredding performance machine disguised as a luxury sedan or coupe. Its buyers are chasing adrenaline, not range, and they’re willing to pay a premium at the pump for the experience. The AMG C63 is a statement, an experience, and a demonstration of engineering prowess focused on putting a smile on your face with every tap of the accelerator.

City and highway performance

The EPA estimates for the AMG C63 are 18 MPG in the city and 27 MPG on the highway. This difference shows where the C63’s engine performs best. City driving, with its constant stop-and-go, is where the thirsty 4.0L V8 suffers most. Highway cruising allows the engine to settle into a more efficient rhythm and use the 9-speed automatic transmission, which yields much better results. But resist the urge to unleash the car’s immense power, or those highway numbers will quickly fall. This car isn’t about restraint; it’s about controlled aggression.

Annual fuel cost

The EPA estimates that you’ll spend $2,750 per year on fuel with the 2020 AMG C63. This figure is based on driving 15,000 miles per year and using national average fuel prices. Your actual fuel costs will vary depending on your driving habits and where you live. If you spend most of your time carving canyons or drag racing at stoplights, expect to significantly exceed that number, especially since the car requires premium fuel. However, it’s a price most C63 owners are willing to pay for the performance this car delivers.

Real-world expectations

The EPA numbers should be considered optimistic. In real-world driving, especially for those who actually push the AMG C63, expect to see figures closer to 15-16 MPG in mixed driving. The temptation to hear the V8 roar and feel the acceleration is too great to resist. A light foot isn’t a common trait among AMG C63 drivers. Weekend track days and spontaneous backroad blasts will further diminish fuel economy. This isn’t a Prius; it’s a performance beast, so manage your expectations accordingly.

How it compares

The AMG C63 exists in a small segment, but it has competition. The BMW M3 Competition offers similar performance, but manages a slightly better 16 MPG city / 23 MPG highway, according to the EPA. The Audi RS5 Sportback, with its turbocharged V6, achieves 18 MPG city / 26 MPG highway. These differences, while seemingly minor on paper, can add up over time. However, buyers often prioritize the AMG C63’s unique character and V8 soundtrack over marginal fuel savings. To see AMG MPG across all years, check out the MPG chart.

Tips to maximize efficiency

While the AMG C63 isn’t designed for maximum fuel efficiency, a few techniques can help you get a bit more out of each tank. Avoid aggressive acceleration and hard braking whenever possible. Smooth, controlled inputs will reduce fuel consumption, especially in city driving.

Use the car’s drive modes. Selecting “Comfort” mode will tame the throttle response and shift earlier, which promotes better fuel economy during less spirited driving. It’s not going to transform the C63 into a hybrid, but it can make a difference.

Ensure your tires are properly inflated, as underinflated tires increase rolling resistance, which negatively impacts fuel economy. Check your tire pressure regularly and maintain the recommended levels.

Consider your route. Avoiding stop-and-go traffic will greatly improve fuel economy, so opt for routes with less congestion and more consistent speeds if possible. This is especially important in urban environments where the C63’s fuel efficiency suffers the most.
