83 MPG equivalent combined might seem like a misprint for a large luxury SUV, but that’s precisely what the 2024 Mercedes-Benz EQS 580 4matic achieves. This isn’t your typical gas-guzzling behemoth; it’s a fully electric SUV designed for buyers who prioritize sustainability without sacrificing luxury or performance. This shopper values a quiet cabin, rapid acceleration, and cutting-edge technology, and they understand that electric vehicles offer a different kind of “fuel economy” than their gasoline counterparts.

City and highway performance

The EPA rates the EQS 580 4matic SUV at 85 MPG equivalent in the city and 81 MPG equivalent on the highway. This slight edge in city driving reflects electric vehicles’ inherent efficiency in stop-and-go traffic. Regenerative braking captures energy during deceleration, feeding it back into the battery and minimizing energy waste. On the highway, aerodynamic drag becomes a more significant factor, impacting the efficiency of all vehicles, even EVs. However, the EQS’s advanced aerodynamics and efficient powertrain minimize this effect, resulting in a still-impressive 81 MPG equivalent.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2024 Mercedes-Benz EQS 580 4matic SUV at $900. This figure is based on driving 15,000 miles per year and using the national average electricity prices. Your actual costs may vary depending on electricity rates in your area and your individual driving habits. However, the $900 figure provides a valuable benchmark for comparing the running costs of the EQS 580 with those of gasoline-powered luxury SUVs. Comparing all Mercedes Benz fuel economy data can provide additional insight.

Real-world expectations

While the EPA estimates provide a standardized comparison, real-world range and efficiency can vary. Factors like driving style, ambient temperature, and the use of climate control can all impact the EQS 580’s actual performance. Aggressive acceleration, frequent use of “Sport” mode, and consistently driving at high speeds will deplete the battery faster.

Similarly, extremely cold temperatures can reduce battery capacity and range. With mindful driving and proper charging habits, most owners can expect to achieve numbers close to the EPA estimates. Dive into the EQS MPG across all years to better understand long-term electric performance.

How it compares

The EQS 580 4matic SUV occupies a unique space in the luxury SUV market. The gasoline powered Mercedes-Benz GLS 450, for example, achieves just 23 MPG combined, making the all-electric EQS a far more environmentally friendly option. Another all-electric SUV competitor, such as the BMW iX xDrive50, achieves a comparable 86 MPG equivalent combined. The Rivian R1S, another three-row electric SUV, is rated at 76 MPG combined. These comparisons are important for the environmentally conscious luxury buyer who wants to minimize their carbon footprint without compromising on prestige or performance. These buyers are acutely aware of the trade-offs and actively seek out alternatives like the EQS 580.

Tips to maximize efficiency

Use regenerative braking to its fullest potential. The EQS 580 offers adjustable regenerative braking modes. Experiment with different settings to find the one that best suits your driving style and maximizes energy recovery. Coasting whenever possible allows the vehicle to slow naturally, capturing kinetic energy instead of wasting it through friction braking.

Precondition the cabin before you drive. While the EQS is plugged in, use the Mercedes me connect app to preheat or precool the cabin. This reduces the energy drain on the battery once you’re on the road, preserving range, especially in extreme temperatures.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, which reduces efficiency. Regularly check your tire pressure and inflate them to the recommended levels. This simple step can have a noticeable impact on your EQS 580’s range.

Minimize accessories that draw power. Reduce your use of energy-intensive features like seat heaters, auxiliary lights, and high audio volume, especially during long trips. While these features provide comfort and convenience, they also draw power from the battery and decrease overall efficiency.

Plan your routes and charging stops carefully. Use navigation apps to identify charging stations along your route and factor in charging time when planning long journeys. This proactive approach minimizes range anxiety and ensures a smooth and efficient driving experience.
