20 MPG combined is what you can expect when driving a 2015 Mercedes-Benz AMG C63. Owners accept this number, perhaps grudgingly, because it’s the price for handcrafted AMG performance, thunderous V8 sounds, and visceral excitement few other sedans offer. This isn’t a car bought for efficiency; it’s a car bought for the experience. The low MPG simply becomes a footnote.

City and highway performance

The EPA estimates the AMG C63 gets 18 MPG in the city and 24 MPG on the highway. These figures are for comparison, but your actual MPG will depend on how you drive. The city MPG will drop if you often use the 4.0L twin-turbo V8’s instant torque. The highway MPG is possible if you resist passing everyone. The 7-speed automatic transmission, while smooth and responsive, is geared for performance more than saving gas. A lighter foot will get better results, but judicious throttle use isn’t a priority for most AMG C63 drivers.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2015 Mercedes-Benz AMG C63 at $2,900. This is based on driving 15,000 miles per year, with 55% in the city and 45% on the highway, using the national average fuel price for premium gasoline, a requirement for this high-performance engine. While a significant expense, C63 owners likely expect higher running costs, considering the car’s premium tires, maintenance, and insurance. Understanding the $2,900 annual fuel cost helps set expectations for ownership.

Real-world expectations

While the EPA figures are a baseline, real-world MPG for the 2015 AMG C63 often varies. Drivers in congested cities who frequently drive aggressively can expect numbers closer to the city MPG, maybe even lower. Those who use the car for longer highway trips and drive conservatively may achieve or exceed the EPA’s 24 MPG highway estimate. Many C63 owners probably don’t obsessively track fuel consumption; the performance and driving enjoyment are more important.

How it compares

The 2015 AMG C63’s fuel economy is similar to its rivals. The BMW M3 of the same era, with its turbocharged inline-six engine, gets about 17 MPG city and 26 MPG highway. The Audi RS5, with a naturally aspirated V8, gets about 16 MPG city and 26 MPG highway. These small differences probably won’t sway buyers because performance and brand are more important than minor MPG gains. However, those considering other options can see AMG MPG across all years.

Tips to maximize efficiency

The AMG C63 isn’t designed for hypermiling, but here are some ways to improve its fuel efficiency. First, anticipate traffic and minimize hard acceleration and braking. Smooth driving reduces fuel use, especially in city traffic. Remember that the car’s power can tempt you to drive less efficiently.

Make sure your tires are properly inflated. Underinflated tires increase rolling resistance, which lowers fuel economy. See the sticker on the driver’s side doorjamb for the recommended tire pressure. This is a simple way to improve MPG without losing driving enjoyment.

Avoid carrying extra weight in the car. Extra weight increases the engine’s workload and lowers fuel economy. Remove unnecessary items from the trunk or passenger area. For example, remove your golf clubs if you aren’t going to the course.

Carefully select the car’s driving modes. While “Sport” and “Sport+” modes improve performance, they also burn more fuel. Choose “Comfort” mode when cruising on the highway or in low-demand situations. Being aware of driving modes will affect mileage.
