20 MPG combined isn’t going to win the 2016 Mercedes-Benz AMG C63 any fuel-sipping awards, but that’s not the point. This is a fire-breathing, German-engineered muscle car disguised as a luxury sedan. The target demographic here is a driving enthusiast who values performance and pedigree over Prius-like efficiency. They prioritize the guttural roar of the hand-built 4.0L V8 and the precise handling over saving money at the pump. They are willing to trade MPG for the experience this AMG machine delivers.

City and highway performance

The EPA estimates suggest 18 MPG in the city and 24 MPG on the highway. The city figure reflects the constant stop-and-go driving typical of urban environments, situations where the C63’s strong power is often restrained but the engine is still consuming fuel. The highway number offers a slightly rosier picture, as consistent speeds allow the engine to settle into a more efficient rhythm, although aggressive use of the accelerator will quickly negate any gains. These are just estimates; your mileage will vary depending on your driving style and road conditions. Those who embrace the AMG lifestyle and consistently use the car’s performance capabilities will likely find their real-world numbers closer to the city rating, regardless of where they spend most of their time.

Annual fuel cost

The EPA estimates that owners of the 2016 Mercedes-Benz AMG C63 will spend approximately $2,900 per year on fuel. This figure is based on driving 15,000 miles annually, with a mix of city and highway driving, using the national average fuel prices at the time of calculation. This is just an average; fluctuating fuel prices and individual driving habits will significantly influence the actual amount spent. A lead-footed driver racking up primarily city miles will see a substantially higher annual cost, while someone with a lighter touch and longer highway commutes might fare a bit better. Given the premium fuel requirement typical of performance vehicles, expect to pay a noticeable sum at each fill-up.

Real-world expectations

While official EPA estimates provide a baseline, real-world mileage for the AMG C63 is often lower, especially if you frequently engage in spirited driving. Aggressive acceleration, frequent braking, and prolonged idling can drastically reduce fuel economy. Owners who primarily use the vehicle for short trips in urban environments will likely observe numbers closer to the 15-17 MPG range. However, with careful driving and a focus on maintaining steady speeds on the highway, it’s possible to achieve figures approaching the EPA’s 24 MPG estimate. Buying an AMG C63 and consciously trying to maximize fuel efficiency is, for most owners, a contradiction. Most are willing to accept the fuel bill as part of the price for owning such a potent machine.

How it compares

Compared to its peers, the 2016 AMG C63’s fuel economy is generally in line with other high-performance sedans. For instance, a comparable BMW M3 with the automatic transmission delivers around 17 MPG city and 24 MPG highway. The Cadillac ATS-V, another competitor, posts figures similar to the BMW. Given the performance bracket they occupy, these cars aren’t vying for efficiency; their focus is on delivering exhilarating driving experiences. Someone considering all Mercedes Benz fuel economy data will not find class-leading fuel economy here. The buyer looking at AMG MPG across all years knows this trade-off. They accept that fuel economy is secondary to the raw power and dynamic handling that these vehicles offer.

Tips to maximize efficiency

While the AMG C63 isn’t designed for frugality, there are a few techniques that can help get slightly better fuel economy. Avoid aggressive acceleration and hard braking. A smooth, consistent driving style will significantly reduce fuel consumption, especially in city driving.

Use the “Comfort” driving mode when you’re not actively seeking performance. This mode typically softens throttle response and optimizes shift points for efficiency, allowing the engine to operate in a more economical range.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, which reduces fuel economy. Check your tire pressure regularly and inflate them to the manufacturer’s recommended specifications.

Minimize idling. Idling consumes fuel without covering any distance. If you’re stopped for more than a minute, it’s generally more efficient to turn off the engine and restart it when you’re ready to go. This is especially true with a larger displacement engine like the AMG’s V8.

Keep up with routine maintenance. A well-maintained engine runs more efficiently. Regular oil changes, air filter replacements, and spark plug checks can help optimize fuel economy.
