The 2024 Mercedes-Benz EQS 580 4matic achieves a combined fuel economy of 96 MPG, an exceptional figure that redefines what’s possible in a flagship luxury sedan. Because the EQS 580 is fully electric, this is an MPGe rating that represents how many miles the car can travel on the equivalent of one gallon of gasoline. The EQS 580 is designed for buyers who demand opulent comfort, groundbreaking technology, and a commitment to sustainability. For them, that 96 MPGe is a significant selling point alongside the massage seats and Burmester sound system.

City and highway performance

The EPA estimates the 2024 Mercedes-Benz EQS 580 4matic at 95 MPGe in the city and 98 MPGe on the highway. This minimal variation between city and highway driving shows the efficiency of electric powertrains, which are less susceptible to the stop-and-go penalties that affect internal combustion engines. In dense urban settings, the EQS 580 uses regenerative braking, capturing energy during deceleration and feeding it back into the battery pack. This explains the high city rating. The slightly higher highway rating suggests optimal efficiency at consistent cruising speeds, minimizing energy expenditure related to frequent acceleration.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2024 Mercedes-Benz EQS 580 4matic to be $800. This calculation is based on driving 15,000 miles per year and using national average electricity prices. This $800 figure makes the EQS 580 very economical to “fuel” compared to other vehicles of similar size and luxury appointments. This figure is tied to national averages; specific charging habits and electricity rates can easily influence real-world costs, either positively or negatively.

Real-world expectations

The EPA’s 96 MPGe provides a useful benchmark, but real-world fuel economy in the EQS 580 4matic depends on various factors. Aggressive driving, frequent use of climate control, and carrying heavy loads all impact energy consumption. However, using the vehicle’s driving modes and pre-conditioning the cabin while plugged in can help optimize range. Someone living in a region with extreme temperatures will likely see a decrease in the range as well.

How it compares

The EQS 580 4matic compares well to other electric luxury sedans in efficiency. The Tesla Model S Long Range achieves an EPA-estimated 120 MPGe combined, giving it a slight edge in overall efficiency, but in a car that is arguably less focused on outright luxury. The Porsche Taycan 4S comes in at around 79 MPGe combined, offering a sportier driving experience but with compromised efficiency. For buyers prioritizing the luxurious experience synonymous with the Mercedes-Benz badge, the EQS 580 balances efficiency and lavishness. For a broader perspective, consider checking EQS MPG across all years.

Tips to maximize efficiency

Take advantage of the EQS 580’s regenerative braking settings. Experiment with different levels of regeneration to find a mode that suits your driving style and maximizes energy recovery. More aggressive regeneration allows the car to slow down considerably when lifting off the accelerator, which further helps improve the MPGe.

Pre-condition the cabin while the vehicle is plugged in, especially during extreme temperatures. This allows you to heat or cool the interior using grid power, reducing the energy demand on the battery when you start driving. This maximizes efficiency.

Pay attention to tire pressure. Properly inflated tires reduce rolling resistance, which translates into improved MPGe. Consult the sticker on the driver’s side doorjamb for the recommended tire pressure.

Limit aggressive acceleration and high-speed driving. Rapid acceleration depletes the battery quickly. Maintaining a smooth, moderate pace not only extends the vehicle’s range but also enhances the overall driving experience in a luxury sedan like the EQS 580.

Use the car’s driving modes and select the “Eco” mode, which optimizes various vehicle systems for efficiency. This mode usually reduces throttle response and adjusts climate control settings to conserve energy, allowing an additional bit of range.
