The 2025 Mercedes-Benz EQB 350 4MATIC achieves an 87 MPGe combined rating. This number shows two things about this compact luxury SUV: it’s electric and efficient for its class. The rating represents a commitment to a premium, zero-emissions driving experience in a functional, family-friendly vehicle. Buyers of the EQB 350 4MATIC are often urban and suburban families or professionals who value Mercedes-Benz luxury, technology, and design. They are also aware of their environmental impact and the cost of traditional fuels. They accept its fuel economy because it is a step forward in sustainable mobility without giving up the brand prestige or all-weather capability they expect.

City and highway performance

The 87 MPGe combined efficiency breaks down to 89 MPGe in the city and 85 MPGe on the highway. These numbers are good for a vehicle the EQB’s size—an estimated 4,700-pound electric crossover with all-wheel drive, designed to seat up to seven passengers. The higher city rating is typical for EVs, where regenerative braking can recover a lot of energy during stop-and-go traffic. Internal combustion engines cannot match this advantage. For the EQB 350 4MATIC’s main buyers, this city efficiency is important. They drive in busy areas, do school drop-offs, and commute daily, activities that benefit from the instant torque and quiet operation of the dual electric motors. The 85 MPGe highway figure, while a bit lower, still means excellent efficiency for sustained speeds, making longer weekend trips economical and reducing range anxiety. This balance makes the EQB a versatile electric vehicle that can handle city driving and open roads with sustainable performance.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2025 Mercedes-Benz EQB 350 4MATIC at a low $850 per year. This is based on driving 15,000 miles per year and national average electricity prices. For buyers switching from a gasoline-powered premium SUV, this is often a strong financial reason to choose an electric vehicle. A comparable gasoline luxury SUV getting 25 MPG combined could easily have annual fuel costs upwards of $2,000 to $3,000 at current national average gasoline prices. The EQB 350 4MATIC’s $850 annual cost saves a lot of money that can be used for other expenses or investments. This predictable and much lower operating cost is a key difference and a major reason why people buy this vehicle, supporting their choice of Mercedes-Benz’s electric future.

Real-world expectations

Official EPA ratings are a good benchmark, but real-world efficiency for the EQB 350 4MATIC will naturally vary. Drivers who often drive fast, use the 288 horsepower (estimated) often, or frequently drive in extreme cold without preconditioning will likely see MPGe figures a bit below the official ratings. On the other hand, those who accelerate gently, use regenerative braking fully, and use the vehicle’s intelligent navigation and pre-entry climate control can often meet or slightly beat the EPA estimates. The EQB’s driver-assistance technologies and configurable driving modes (like Eco mode) help owners get better efficiency without giving up performance. Most EQB owners, used to a premium vehicle, will find its real-world efficiency a pleasant surprise, consistently better than their previous gasoline vehicles.

How it compares

In the growing compact luxury EV SUV class, the EQB 350 4MATIC stands out with its mix of practicality, luxury, and efficiency. Let’s look at some competitors. The Tesla Model Y Long Range, a common benchmark, usually gets around 125 MPGe combined. While higher, the Model Y offers a different look and driving experience, often preferred by those who want raw efficiency and advanced tech over traditional luxury comforts. Another competitor, the Audi Q4 e-tron 50 quattro, generally gets around 95 MPGe combined, offering a more direct comparison in terms of brand and interior refinement, though the EQB often has a more spacious and versatile interior, especially with the optional third row. The Volvo XC40 Recharge Twin Motor, another strong contender, typically posts combined figures in the high 80s MPGe, often around 88 MPGe, making it very similar to the EQB but with a distinctly Scandinavian design. Buyers choose the EQB 350 4MATIC despite slightly lower MPGe figures than some rivals because they value the Mercedes-Benz experience, reliable interior materials, the strong physical and digital interfaces, the three-pointed star on the hood, and the unique proportions that allow for cargo and passenger flexibility.

Tips to maximize efficiency

Getting the most efficiency from your 2025 Mercedes-Benz EQB 350 4MATIC involves a few simple practices for its electric powertrain.

Always pre-condition the cabin while the vehicle is still plugged in, especially in extreme temperatures. This uses grid power to heat or cool the battery and interior, meaning less range is used on these energy-intensive tasks once you start driving. Doing so can significantly extend your practical range and improve overall efficiency.

Use the regenerative braking fully. The EQB has adjustable regeneration levels, often available via paddle shifters. Try the stronger regeneration settings (often called “one-pedal driving”) to learn to coast more and rely on the vehicle to recover energy, instead of using the friction brakes.

Maintain proper tire pressure. Underinflated tires increase rolling resistance, making the electric motors work harder and use more energy. Check your tire pressure regularly, ideally monthly, and keep them inflated to the manufacturer’s recommended specifications found on the door jamb placard.

Drive smoothly and avoid fast acceleration and hard braking. While the EQB 350 4MATIC has good acceleration, frequently using its full power will naturally drain the battery faster. A relaxed driving style saves energy and makes passengers more comfortable in this luxury SUV.

Consider using the vehicle’s Eco driving mode for your daily commutes. This mode often softens accelerator response, optimizes climate control settings, and encourages efficient driving without severely limiting comfort or utility.
