The 2019 Mercedes-Benz AMG E53 4matic Plus’s 24 MPG combined fuel economy isn’t going to win any green awards, nor is it intended to. This is a performance-oriented machine draped in the elegant lines of the E-Class sedan, a vehicle designed for drivers who prioritize exhilarating acceleration and confident handling above all else. The E53 buyer understands that a strong, turbocharged inline-six with hybrid assist comes at a cost, and they’re willing to pay it.

City and highway performance

The 2019 AMG E53 achieves an EPA-estimated 21 MPG in the city and 28 MPG on the highway. This difference reflects the engine’s tuning and the demands placed upon it. City driving, with its constant stop-and-go, will inevitably use the turbocharger and electric auxiliary compressor more frequently, thus decreasing fuel efficiency. On the open road, the E53 can settle into a more relaxed cruise, taking advantage of its nine-speed automatic transmission to maintain lower engine speeds and optimize fuel consumption. However, the temptation to exploit the engine’s considerable power will always be present, impacting real-world highway MPG.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2019 Mercedes-Benz AMG E53 at $2,400. This figure is based on driving 15,000 miles per year, with a mix of city and highway driving, and using the national average fuel price at the time of calculation. Keep in mind that actual fuel costs will fluctuate depending on individual driving habits, local fuel prices, and the grade of fuel used. While the E53 doesn’t require premium fuel, its high-performance nature benefits from it, and many owners opt for it.

Real-world expectations

Drivers should expect slightly below the EPA estimates. The AMG E53 is a car that encourages spirited driving, and few owners will resist the urge to fully use its 429 horsepower and 384 lb-ft of torque. Expect combined MPG to be somewhere between 20 and 24 MPG in everyday use, with highway figures potentially exceeding the EPA estimate during long, steady cruises. However, frequent bursts of acceleration and enthusiastic cornering will quickly diminish fuel efficiency.

How it compares

Compared to its rivals, the E53’s fuel economy is largely in line with expectations for its performance class. The BMW M550i xDrive, packing a 4.4-liter V8, manages around 17 MPG city and 25 MPG highway. The Audi S6, with its turbocharged V6, is rated at 18 MPG city and 28 MPG highway. The E53’s mild-hybrid system helps it to stay competitive while still delivering an engaging driving experience. These numbers are important to the target buyer, but outright economy is rarely the deciding factor. They want all all Mercedes Benz fuel economy data to be as competitive as possible, but aren’t cross-shopping against hybrids.

Tips to maximize efficiency

Use the car’s drive modes intelligently. Comfort mode prioritizes fuel efficiency by softening throttle response and optimizing gear selection. Reserve Sport and Sport+ modes for occasions when performance is important, as they notably increase fuel consumption.

Take advantage of the E53’s regenerative braking system. Anticipate stops and allow the car to decelerate gradually, maximizing the energy captured by the electric motor. Avoid harsh braking, as it reduces the system’s effectiveness.

Ensure proper tire inflation. Underinflated tires increase rolling resistance, which negatively impacts fuel economy. Check tire pressures regularly and maintain them at the recommended levels, typically found on a sticker inside the driver’s side doorjamb.

Minimize unnecessary weight. Remove any excess cargo from the trunk, as added weight requires more energy to accelerate and maintain speed. Remember that a lighter car is a more efficient car.

Consider that AMG MPG across all years shows incremental improvements as powertrain technology advances. While you are unlikely to buy an AMG for its fuel efficiency, newer models will typically extract more performance for each gallon of fuel.
