82 MPG combined makes the 2024 Mercedes-Benz AMG EQS 4matic Plus a performance car with near-unheard of efficiency. This vehicle is a technological tour de force priced north of $150,000, aimed at hyper-connected executives and early adopters who prize quiet operation, blistering acceleration, and a certain sense of environmental responsibility (or at least the image thereof). For this buyer, fuel economy is not the primary concern, but rather an unexpected and welcome element in a vehicle that already delivers so much.

City and highway performance

The EPA estimates the AMG EQS 4matic Plus achieves 79 MPG in the city and 85 MPG on the highway. These figures reflect the efficiency of its electric powertrain and regenerative braking system. The city figure benefits from the frequent opportunities for regeneration, allowing the vehicle to recoup energy during stop-and-go traffic. The highway figure, perhaps surprisingly higher, demonstrates the car’s aerodynamic efficiency and optimized power management at cruising speeds. These numbers are impressive for an AMG product and impressive compared to virtually anything with four wheels and a steering wheel, regardless of performance aspirations.

Annual fuel cost

According to EPA estimates, the annual fuel cost for the 2024 Mercedes-Benz AMG EQS 4matic Plus is a mere $900. This figure is based on driving 15,000 miles per year and using national average electricity prices. While individual electricity costs will vary depending on location and charging habits, this $900 figure highlights the potential for significant savings compared to a traditional gasoline-powered AMG vehicle. This is pocket change for the target demographic, but it’s another selling point in a vehicle brimming with them.

Real-world expectations

While the EPA estimates provide a valuable baseline, your actual fuel economy will depend on many factors. Driving style, ambient temperature, and terrain all play a role. Aggressive acceleration, frequent use of the car’s prodigious power, and consistently high speeds will all reduce your MPG. Conversely, gentle acceleration, using regenerative braking whenever possible, and optimizing climate control settings will help you achieve figures closer to the EPA estimates.

As with any electric vehicle, preconditioning the cabin while still plugged in can also improve range, especially in colder weather. Pay attention to the vehicle’s energy consumption monitor, which provides real-time data to help drivers adjust their behavior for optimal efficiency.

How it compares

Compared to other high-performance luxury vehicles, the 2024 AMG EQS 4matic Plus sits in a league of its own. The Porsche Taycan Turbo S, an all-electric competitor, manages only 68 MPG combined. The Tesla Model S Plaid, another performance EV, achieves 116 MPGe combined. However, the Model S Plaid delivers its performance with a different aesthetic and ethos.

Shifting to gasoline-powered rivals shows an even starker contrast. A Mercedes-AMG S63, for example, achieves around 18 MPG combined. This comparison illustrates the fuel economy advantage of the AMG EQS 4matic Plus and the shifting landscape of performance vehicles in general. Buyers now expect performance and efficiency, and the AMG EQS 4matic Plus delivers both. See all Mercedes Benz fuel economy data for more comparison.

Tips to maximize efficiency

Use the regenerative braking system. The AMG EQS 4matic Plus offers adjustable regenerative braking settings. Experiment with these settings to find the level that best suits your driving style and maximizes energy recovery. In many situations, the “one-pedal driving” mode will allow you to slow down and even come to a complete stop without using the brake pedal, capturing kinetic energy and feeding it back into the battery.

Optimize your climate control settings. Heating and cooling the cabin can consume a significant amount of energy. Use the pre-conditioning feature to warm or cool the cabin while the car is plugged in, reducing the energy demand on the battery. When driving, use the seat heaters and ventilated seats instead of cranking up the HVAC system. Strategically positioning air vents can also improve efficiency.

Monitor tire pressure. Maintaining the correct tire pressure reduces rolling resistance and improves fuel economy. Check your tire pressure regularly, especially during temperature fluctuations, and inflate your tires to the recommended pressure listed on the doorjamb or in the owner’s manual.

Plan your routes strategically. Avoid unnecessary stops and starts, and choose routes with smoother traffic flow whenever possible. Use the navigation system to identify the most efficient route to your destination, taking into account traffic conditions and elevation changes. Predict traffic conditions and drive accordingly.

Resist the urge to unleash full power for every stoplight sprint. While the AMG EQS 4matic Plus offers incredible acceleration, frequent use of the car’s maximum power will quickly deplete the battery. Reserve the full acceleration for when you truly need it, and adopt a more mellow driving style for everyday commuting. This simple change can dramatically improve your overall range.
