The 2024 Mercedes-Benz EQB 350 4matic’s 87 MPG combined rating places it squarely in the electric vehicle (EV) realm, a necessary attribute for this compact seven-seater chasing family duty while wearing the three-pointed star. This is an electric, all-wheel-drive crossover aimed at urban families and eco-conscious buyers who need flexible passenger and cargo configurations without sacrificing luxury or brand cachet. Acceptance of this “fuel economy” depends less on squeezing every last mile and more on transitioning to a world free from gas stations.

City and highway performance

The EPA estimates the EQB 350 4matic to deliver 89 MPG in the city and 85 MPG on the highway. These figures reflect the electric motor’s strengths: instant torque for city driving and consistent efficiency at highway speeds. Electric motors perform well in stop-and-go conditions, where regenerative braking recovers energy, contributing to that higher city MPG. It’s important to remember these are estimates. Real-world conditions, driving style, and even ambient temperature can significantly impact the actual range and efficiency. The more conservative you are as a driver, the more likely you are to achieve these figures.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2024 Mercedes-Benz EQB 350 4matic at $850. This figure is based on driving 15,000 miles per year and using national average electricity prices. Considering that traditional gasoline vehicles easily surpass this annual expenditure, the EQB presents a strong case for long-term savings. Electricity prices vary considerably by location and time of day, so your actual cost will depend on your local utility rates and charging habits. Those who can charge at home during off-peak hours will likely see even lower annual costs.

Real-world expectations

While the EPA provides a standardized way to compare vehicles, real-world range will always determine EV ownership satisfaction. The EQB 350 4matic’s range is an important factor for many buyers.

Factors like aggressive acceleration, sustained high speeds, running the air conditioning or heater, and carrying heavy loads all reduce range. Owners who adapt their driving styles and pre-condition the cabin while plugged in will be closer to the EPA estimates than those who don’t. For a deeper dive, explore EQB MPG across all years.

How it compares

The Audi Q4 e-tron, another luxury electric crossover, achieves a combined EPA rating of around 95 MPG, offering slightly better efficiency. The Tesla Model Y Long Range boasts a notably higher 122 MPGe combined. These differences highlight the competitive landscape and underscore the importance of considering range and efficiency alongside price and features. The EQB may not lead in pure efficiency, but it provides Mercedes-Benz’s renowned interior quality and brand prestige. The BMW iX, while larger and more expensive, delivers around 86 MPGe, demonstrating that efficiency doesn’t directly correlate with size or price, but rather, specific powertrain design and optimization. Comparing all Mercedes Benz fuel economy data against other brands shows how the EQB balances luxury, practicality, and electric efficiency within the Mercedes lineup.

Tips to maximize efficiency

Regenerative braking is helpful. The EQB allows adjustment of regen levels via paddles on the steering wheel. Maximize regen in city driving to recapture energy that would otherwise be lost as heat, thereby extending your range. Experiment with different regen settings to find what suits your driving style best, and anticipate stops to maximize energy recovery.

Pre-condition the cabin while plugged in. Heating or cooling the interior while the vehicle is connected to a charger draws power from the grid instead of the battery, preserving your driving range. This is especially important in extreme temperatures, as HVAC systems can significantly impact EV efficiency.

Maintain optimal tire pressure. Under-inflated tires increase rolling resistance, forcing the electric motor to work harder and reducing efficiency. Regularly check and maintain the recommended tire pressure, typically found on a sticker inside the driver’s side doorjamb. This simple act can have a noticeable impact on your range.

Limit aggressive acceleration and high-speed driving. Electric motors deliver instant torque, making rapid acceleration tempting. However, frequent bursts of speed consume energy quickly. Similarly, aerodynamic drag increases significantly at higher speeds, reducing efficiency. Adopt a smoother, more consistent driving style to maximize your range.

Use the car’s energy consumption display. Familiarize yourself with the EQB’s energy consumption display, which provides real-time and historical data on your driving efficiency. Use this information to identify areas where you can adjust your driving habits to improve efficiency. You may notice that certain routes or driving conditions consistently result in higher energy consumption, allowing you to plan accordingly.
