The 2024 Mercedes-Benz EQS 450 Plus SUV has an EPA-estimated 86 MPG combined, a very good figure highlighting its position as a leading electric SUV. This means premium driving with potentially lower fuel costs, avoiding the typical environmental impacts of large luxury vehicles. The EQS 450 Plus SUV appeals to affluent buyers who value lower fuel costs, cutting-edge technology, design, and the convenience of home charging, as much as they appreciate the Mercedes-Benz branding and the EQS’s comfortable interior.

City and highway performance

The EQS 450 Plus SUV gets an estimated 88 MPG in the city and 83 MPG on the highway. This slight advantage in urban driving reflects the efficiency of electric motors at lower speeds when regenerative braking is more effective. City driving, often involving stop-and-go traffic, provides plenty of opportunities for the EQS to recapture energy and extend its range. On the highway, aerodynamic drag has a greater impact, which reduces efficiency slightly, but 83 MPG is still exceptional for a vehicle of this size.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2024 Mercedes-Benz EQS 450 Plus SUV is $850. This estimate assumes 15,000 miles of driving per year, using national averages for electricity costs. This demonstrates the potential savings compared to traditional gasoline-powered SUVs, where annual fuel costs can easily exceed $3,000 or more. The specific cost for each driver will depend on their local utility rates and driving habits, but the $850 figure demonstrates the substantial economic benefit of choosing an all-electric vehicle like the EQS.

Real-world expectations

Getting the EPA-estimated 86 MPG in real-world driving requires a conscious effort to optimize energy consumption. Electric powertrains are naturally efficient, so these numbers are generally attainable. Factors such as driving style, ambient temperature, and the use of climate control can impact efficiency. Aggressive acceleration and high-speed driving will deplete the battery faster, while moderate speeds, smooth acceleration, and careful regenerative braking will help maximize range. Colder temperatures may also reduce battery performance, as is the case with most EVs.

How it compares

The EQS 450 Plus SUV stands out in the growing field of all-electric luxury SUVs. The Tesla Model X Long Range achieves around 102 MPGe combined, even with its performance focus. The BMW iX xDrive50, a key competitor, returns around 86 MPGe combined, closely matching the EQS. The Audi e-tron (discontinued after 2024) achieved around 78 MPGe combined in its final year. These comparisons are important for buyers because range and efficiency are key considerations alongside luxury features and brand cachet. Each vehicle offers a unique driving experience and set of features, and the EQS 450 Plus SUV is competitive in terms of efficiency and running costs.

Tips to maximize efficiency

Effectively use the EQS’s regenerative braking system. The vehicle offers adjustable levels of regeneration, letting you customize the braking force when you lift off the accelerator. Experiment with the different settings to find what works best for your driving style. Try to anticipate traffic flow to get the most energy back.

Precondition the cabin while the vehicle is plugged in, especially during very hot or cold weather. This lets you heat or cool the interior using grid power instead of the battery, saving range for driving. The Mercedes-Benz Me app offers remote control of climate settings.

Pay attention to tire pressure. Properly inflated tires reduce rolling resistance, improving efficiency and extending range. Check your tire pressure often and keep it within the recommended range on the door jamb sticker.

Keep extra weight out of the vehicle. Carrying excessive cargo can reduce efficiency, so remove items you don’t regularly need. Every pound affects the range of an electric vehicle.
