Seventy-seven MPG combined: that figure alone should tell you the 2022 Mercedes-Benz AMG EQS 4matic Plus is not your average AMG. This is an all-electric performance flagship, and those 77 miles per gallon represent its gasoline-equivalent fuel efficiency, a crucial metric for buyers who demand both thrilling acceleration and lower fuel costs.

City and highway performance

The EPA numbers reveal a consistent energy consumption profile for the AMG EQS. Its 76 MPG city rating and 78 MPG highway rating demonstrate that its electric powertrain delivers fairly stable efficiency across varying driving conditions. Electric cars often achieve similar MPG in city and highway environments because they rely on regenerative braking in stop-and-go traffic, unlike gasoline-powered vehicles. The AMG EQS uses this capability to recapture energy during deceleration, feeding it back into the battery to extend driving range. This near-identical rating reinforces that the AMG EQS 4matic Plus can handle any driving situation, which is important to buyers in this segment.

Annual fuel cost

The EPA estimates that the annual fuel cost for the 2022 Mercedes-Benz AMG EQS 4matic Plus is $1,000. This figure is based on driving 15,000 miles per year and using national average electricity prices. It is a great number for prospective owners, because while the initial investment might be significant, the long-term savings on fuel can be substantial compared to high-performance gasoline-powered alternatives. Consider that someone covering 15,000 miles in a performance sedan achieving, say, 20 MPG, could easily spend three to four times that amount on gasoline over the course of a year.

Real-world expectations

While the EPA estimates provide a valuable benchmark, real-world fuel economy can vary depending on several factors like driving style, weather conditions, and terrain. Aggressive acceleration and high speeds will drain the battery faster, reducing overall efficiency. However, gentle acceleration and using regenerative braking effectively can extend the driving range beyond the EPA estimates. Keep in mind that external temperatures can also impact battery performance, with extreme cold potentially reducing range, and the type of charger used can also factor into how long it takes to charge the vehicle which can impact the overall economy of the vehicle. Even with a few less MPG, it’s easy to see why people would be interested in all Mercedes Benz fuel economy data.

How it compares

Compared to other high-performance electric vehicles, the AMG EQS is competitive in terms of efficiency. The Porsche Taycan Turbo S, for example, offers exhilarating performance but achieves a lower combined MPGe of 69. The Audi e-tron GT, another close competitor, is rated at 82 MPGe combined. The AMG EQS stands out because of its blistering acceleration, luxurious interior, cutting-edge technology, and a relatively efficient electric powertrain. These vehicles share similar purposes though, so be sure to review AMG MPG across all years. Buyers in this segment aren’t solely focused on ultimate efficiency; they prioritize a combination of performance, luxury, and lower fuel costs. They are willing to accept a slightly lower MPG number than some competitors in exchange for the unique AMG experience and brand cachet.

Tips to maximize efficiency

One of the most effective ways to improve the AMG EQS’s fuel economy is to use regenerative braking efficiently. Anticipate stops and coast whenever possible, allowing the car to recapture energy and recharge the battery. Learn to modulate the accelerator pedal smoothly for optimal efficiency.

Preconditioning the battery and cabin while the car is plugged in can also improve efficiency, especially in cold weather. This reduces the energy demand on the battery once you start driving, maximizing range. Many owners also take advantage of scheduled charging to take advantage of off-peak electricity rates.

Driving in the appropriate drive mode also drastically changes the MPG of the vehicle. Comfort or Eco modes optimize for energy conservation, while Sport or Sport+ modes deliver maximum performance, at the expense of range.

Use the car’s advanced navigation system to plan your routes efficiently. The system can factor in traffic conditions and elevation changes to optimize energy consumption and estimate arrival times accurately.
