96 MPG combined is an impressive figure, but understanding what it represents in the 2022 Mercedes-Benz EQB 350 4matic requires acknowledging that this is an all-electric vehicle. Buyers drawn to the EQB 350 prioritize emissions-free driving and the convenience of home charging above all else. For them, a high “MPG” equivalent is simply confirmation of the EV’s inherent efficiency, not the primary decision driver. This is a vehicle for eco-conscious families who need space and practicality, but are not ready to sacrifice the luxury and technology associated with the Mercedes-Benz brand.

City and highway performance

The EPA rates the 2022 Mercedes-Benz EQB 350 4matic at 98 MPG in the city and 93 MPG on the highway. These numbers reflect the EQB’s electric powertrain, which excels in stop-and-go traffic where regenerative braking captures energy that would otherwise be lost. The slightly lower highway figure is typical for EVs, as aerodynamic drag and the lack of regenerative braking at higher speeds consume more energy. Both figures demonstrate the unwavering efficiency one can expect in this vehicle.

Annual fuel cost

The EPA estimates the annual fuel cost, or more accurately, electricity cost, for the 2022 Mercedes-Benz EQB 350 4matic at $800. This calculation assumes 15,000 miles of driving per year, using the national average electricity price. Individual costs will vary depending on local electricity rates, driving habits, and the percentage of charging done at home versus at public charging stations. Home charging is cheaper, and public charges will vary depending on provider.

Real-world expectations

While the EPA figures provide a standardized benchmark, real-world energy consumption can vary. Factors like ambient temperature, driving style, and usage of climate control can affect the overall range. Aggressive acceleration and frequent use of the air conditioning will reduce range and increase your effective cost per mile. Maintaining a moderate speed and using the EQB’s ECO driving mode will help you achieve closer to the EPA estimates. For more information, check out EQB MPG across all years.

How it compares

The Audi Q4 e-tron, another compact electric SUV, achieves a combined rating of 95 MPGe, mirroring the EQB’s efficiency. Tesla’s Model Y Long Range surpasses both with a 122 MPGe combined rating. However, the EQB differentiates itself with its boxier design and available third-row seating, catering to a specific buyer who values practicality and Mercedes-Benz refinement over outright efficiency. While the Kia Niro EV achieves a combined 113 MPGe, the prestige of the Mercedes-Benz badge and the more reliable standard all-wheel drive of the 350 4matic justify the slightly less favorable numbers for many buyers.

Tips to maximize efficiency

Pre-conditioning is useful. Use the Mercedes-Benz Me app to pre-heat or pre-cool the cabin while the EQB is still plugged in. This draws power from the grid, minimizing the energy needed from the battery once you start driving, especially during extreme weather.

Regenerative braking can be adjusted. Experiment with the different levels of regenerative braking to find the setting that best suits your driving style and local traffic conditions. Increased regeneration puts more energy back into the battery, but can take some getting used to.

Tire pressure matters even more with an EV. Regularly check and maintain the recommended tire pressure. Underinflated tires increase rolling resistance, which decreases and increases energy consumption. Refer to the sticker on the driver’s side doorjamb for the correct pressure.

Consider limiting use of cabin heat. Heating the cabin can be a significant energy draw, especially in cold weather. Use seat heaters and steering wheel heaters to stay comfortable without heavily relying on the climate control system.
