The 2016 Mercedes-Benz AMG E63 S 4matic, with its 5.5L 8-cyl engine, gets 18 MPG combined. This car isn’t a Prius. It’s a hand-built performance sedan, and fuel efficiency isn’t a primary concern for those who buy it. These buyers prioritize fast acceleration and confidence in all weather conditions over saving money at the pump. They want pure performance.

City and highway performance

The EPA estimates the 2016 AMG E63 S gets 15 MPG in the city and 22 MPG on the highway. That’s not surprising, considering the 5.5L twin-turbo V8 under the hood. In stop-and-go traffic, the engine’s power is constantly held back. This results in significant fuel consumption as you accelerate its heavy weight. On the open highway, especially if you’re gentle with the throttle, the engine can cruise more efficiently. This allows you to get close to the EPA’s 22 MPG figure, but driving enthusiastically will quickly reduce that.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2016 Mercedes-Benz AMG E63 S 4matic at $3,200. This is based on driving 15,000 miles per year, with 55% in the city and 45% on the highway, using national average fuel prices. Plan to spend at least $267 per month on gasoline, possibly more if you drive aggressively or if fuel prices increase. The E63 S offers a luxurious experience, but it requires a lot of premium fuel.

Real-world expectations

The EPA provides a standard for fuel economy, but actual MPG can change a lot. Driving style, traffic, and weather all affect it. If you often use the E63 S’s horsepower, expect fuel economy closer to the city rating, or even lower. If you accelerate smoothly and drive at consistent highway speeds, you might get close to, or even slightly exceed the EPA’s highway estimate. To accurately estimate your fuel costs, consider your driving habits and routes. Find all Mercedes Benz fuel economy data on our site.

How it compares

The 2016 AMG E63 S’s fuel economy is typical for high-performance luxury sedans. The BMW M5, for example, gets 17 MPG combined, 14 MPG city, and 22 MPG highway. The Cadillac CTS-V, with its supercharged 6.2L V8, gets 17 MPG combined, 14 MPG city, and 21 MPG highway. The Audi RS 7, known for its design and performance, gets 18 MPG combined. The E63 S’s fuel consumption is a normal cost for this level of power and exclusivity. Before making a decision, see the AMG MPG across all years.

Tips to maximize efficiency

Fuel economy might not be the main concern for E63 S owners, but you can still reduce consumption. Avoid accelerating quickly and braking hard, as these use a lot of fuel. Smooth inputs will help the engine run more efficiently, especially in the city.

Use the car’s drive modes. Comfort mode softens the throttle and changes shift points for better fuel efficiency. Sport and Sport+ modes increase performance, but they also use much more fuel.

Make sure your tires have the right amount of air. Low tire pressure increases rolling resistance, making the engine work harder and burn more fuel. Check and adjust tire pressure regularly.

Reduce the weight in the car. Extra cargo increases the car’s weight, which hurts fuel economy. Remove items you don’t need to lighten the car and remove the roof rack when you aren’t skiing.

On long highway trips, consider using cruise control. Keeping a steady speed can improve fuel consumption. But remember to pay attention and turn off cruise control when needed due to traffic and road conditions.
