19 MPG combined. If you care most about fuel economy, the 2023 Mercedes-Benz AMG E63 S 4Matic Plus isn’t for you. It’s a high-performance car in a luxurious sedan body. It’s built for racetracks, not saving fuel, and those who buy it understand they’re paying for incredible acceleration and driving enjoyment with more trips to the gas station.
City and highway performance
The EPA estimates the AMG E63 S gets 16 MPG in the city and 24 MPG on the highway. These numbers show the impact of driving style. In cities, frequent stops and power bursts reduce fuel economy, as the 4.0L twin-turbo V8 responds quickly even to light pressure on the gas pedal. On highways, the E63 S can go further on a gallon thanks to its advanced engine controls and smooth 9-speed automatic transmission.
Annual fuel cost
The EPA estimates an annual fuel cost of $3,050 for the 2023 Mercedes-Benz AMG E63 S 4Matic Plus. This is based on 15,000 miles per year and national average premium gasoline prices. This significant expense should be part of the cost calculation for potential owners. Keep in mind that real-world fuel costs change based on driving habits, traffic, and the time of year.
Real-world expectations
Don’t count on always getting the EPA numbers. If you drive the E63 S hard, expect fuel economy on the low end of the range. Drivers who are more conservative on the highway might get closer to the EPA highway estimate. The temptation to use the V8’s power will always impact mileage, as this car is built for performance, which uses more fuel.
How it compares
The AMG E63 S offers similar fuel economy to its competitors. The BMW M5 Competition, with its 4.4L twin-turbo V8, gets around 17 MPG city and 25 MPG highway. The Audi RS7, powered by a 4.0L twin-turbo V8, achieves 15 MPG city and 22 MPG highway. These cars prioritize performance over fuel efficiency. If you consider smaller, less powerful options like the Porsche Panamera 4S (21 city/28 highway), you’ll save on gas, with a reduction of power and performance. Buyers looking for all Mercedes Benz fuel economy data can find other options with better efficiency if that’s what they want.
Tips to maximize efficiency
You can minimize fuel use in the AMG E63 S.
Avoid fast acceleration and hard braking, as these significantly reduce fuel economy. Gentle acceleration and braking will make a difference.
Strategically use the car’s driving modes. “Comfort” mode softens the throttle and optimizes the transmission to save fuel. It’s less exciting than “Sport+” or “Race,” but helps conserve fuel during regular driving.
Keep tires properly inflated. Low tire pressure increases rolling resistance, which increases fuel use. Check your tire pressure often and maintain the recommended levels.
Reduce weight in the car. Extra weight requires more energy, more fuel, to move. Remove unnecessary items from the trunk and cabin to reduce the load.
Plan trips to avoid stop-and-go traffic. Constant acceleration and deceleration use a lot of fuel. Routes with fewer traffic lights and less congestion will improve your overall fuel economy in this AMG MPG champ. Or review AMG MPG across all years to see if another choice might be better.
