96 MPG combined is an extraordinary figure, especially for the 2024 Mercedes-Benz EQS 450 Plus. This electric vehicle (EV) redefines expectations for a flagship luxury sedan. It blends opulent comfort, cutting-edge technology, and a commitment to efficiency, targeting affluent buyers interested in lower fuel costs who want the best of both worlds: a statement of luxury and a nod to sustainable living. They are less concerned with outright cost savings and more driven by the prestige of owning a zero-emission vehicle that doesn’t compromise on performance or amenities.

City and highway performance

The EQS 450 Plus shows its efficiency in both city and highway driving. The EPA rates it at 95 MPG in the city and 98 MPG on the highway, the finely tuned electric powertrain and advanced regenerative braking system deliver these numbers. City driving is where the EQS shines, recouping energy with every stop and start. Highway driving shows the aerodynamic design and electric motor efficiency at sustained speeds. These figures highlight the car’s environmental credentials and translate to considerable savings in energy costs compared to traditional gasoline-powered luxury sedans.

Annual fuel cost

The EPA estimates the annual “fuel” cost for the 2024 Mercedes-Benz EQS 450 Plus is $800. This calculation is based on driving 15,000 miles per year and using the national average electricity prices. This $800 figure is an argument for EV adoption, especially for those accustomed to the hefty fuel bills associated with high-performance luxury vehicles. Keep in mind this figure will vary based on individual driving habits, local electricity costs, and access to free charging.

Real-world expectations

While the EPA estimates offer a benchmark, real-world MPG can vary depending on factors. Aggressive acceleration, frequent climate control, and driving in extreme temperatures can impact efficiency. However, the EQS 450 Plus has driving modes and energy-saving features designed to help drivers maximize their range and maintain efficiency. Drivers who prioritize smooth acceleration, regenerative braking, and pre-conditioning features can expect to see results closer to the EPA estimates.

How it compares

The EQS 450 Plus competes with other luxury electric vehicles, each offering performance, range, and efficiency. The Tesla Model S, for example, achieves around 120 MPGe combined in its Long Range configuration, prioritizing range and performance. The BMW i7 xDrive60, rated at around 87 MPGe combined, offers a luxurious experience with a focus on driving dynamics. The Lucid Air Touring boasts an impressive range and a combined MPGe of around 140. These differences matter to buyers in this segment. Some may prioritize range above all else, while others may value the prestige of the Mercedes-Benz brand or the specific features and comfort it offers. Buyers can explore EQS MPG across all years for a full comparison.

Tips to maximize efficiency

Use the EQS’s regenerative braking system. Experiment with different levels of regeneration to find the setting that best suits your driving style and maximizes energy recovery. Aggressive braking wastes energy and reduces overall efficiency.

Take advantage of pre-conditioning. Before setting off, use the Mercedes-Benz app to pre-heat or cool the cabin while the car is still plugged in. This reduces the energy demand on the battery during your drive, especially on cold or hot days.

Drive in “Comfort” or “Eco” mode. These modes optimize the car’s performance for efficiency, limiting acceleration and adjusting other settings to conserve energy. The default “Comfort” mode is usually a good balance between efficiency and performance for daily driving.

Monitor tire pressure. Underinflated tires increase rolling resistance, which reduces fuel economy. Keep your tires properly inflated to the recommended pressure specified on the doorjamb sticker. Use the car’s built-in system to alert you to pressure changes.

Plan your charging strategy. Look for off-peak charging options to reduce electricity costs. Many utility companies offer lower rates during nighttime hours, which can significantly lower your overall “fuel” expenses. Explore all Mercedes Benz fuel economy data for more efficient models.
