87 MPGe combined makes the 2025 Mercedes-Benz EQB 300 4MATIC a remarkably efficient small luxury electric SUV. This isn’t a vehicle designed for shock-and-awe acceleration, but rather for refined urban and suburban living, where its efficiency directly translates to fewer charging stops and lower running costs. The EQB 300 4MATIC targets a demographic that values technology, safety, and the prestige of the Mercedes-Benz badge, but who also prioritize practicality and lower fuel costs in their daily commute and weekend excursions. They recognize that an electric vehicle inherently offers superior “fuel” economy compared to gasoline counterparts, and the EQB delivers on that promise without compromises in luxury or capability.

City and Highway Performance

The EPA rates the 2025 EQB 300 4MATIC at 89 MPGe in the city and 85 MPGe on the highway. This near-even split between city and highway efficiency is characteristic of well-engineered electric vehicles; unlike internal combustion engines that often thrive on consistent highway speeds, electric motors maintain high efficiency across a broader range of operating conditions. In city driving, the EQB benefits significantly from regenerative braking, which captures kinetic energy typically lost as heat during deceleration and converts it back into usable electricity, effectively extending its range. This regeneration is particularly noticeable and beneficial in stop-and-go traffic, where the EQB feels most at home. On the highway, the 85 MPGe figure is still excellent, though high-speed aero drag and the continuous power demand means the vehicle is working harder than it would during urban cruising. The 4MATIC all-wheel-drive system, which provides enhanced traction and stability, has a minimal impact on these figures thanks to intelligent power distribution.

Annual fuel cost

The EPA estimates an annual fuel cost of $850 for the 2025 Mercedes-Benz EQB 300 4MATIC. This figure is derived by assuming 15,000 miles of driving per year and using national average electricity prices. This is a strong indicator of the financial benefits of owning an EV. For the EQB buyer, this remarkably low annual cost is a significant draw. They are often coming from luxury gasoline SUVs that might incur annual fuel bills of $2,500 or more. The $850 cost directly contributes to the vehicle’s value, demonstrating a tangible return on the investment in electric vehicle technology. This low annual expenditure frees up budget for other luxury amenities or simply reduces the overall cost of ownership, making the premium EQB more accessible in the long run.

Real-world expectations

While the EPA ratings provide an excellent baseline, real-world fuel economy can always vary. The 87 MPGe combined figure for the EQB 300 4MATIC is highly achievable for most drivers, particularly those who typically use their vehicle for daily commuting and weekend errands. Factors such as aggressive driving, frequent use of climate control, extreme external temperatures, and hauling heavy loads will naturally reduce efficiency. However, the EQB’s target audience, typically responsible and conscious drivers, tends to operate their vehicles in a manner conducive to maintaining optimal efficiency. The reliable range estimation and accurate range predictor in the MBUX infotainment system also help drivers manage their expectations and avoid range anxiety. The EQB’s relatively compact size and aerodynamic profile further contribute to its real-world efficiency, ensuring that the EPA numbers are not merely theoretical benchmarks but practical guidelines for everyday driving.

How it compares

The 2025 EQB 300 4MATIC stands out in the burgeoning compact luxury EV SUV segment. Consider its closest competitors. The Audi Q4 e-tron 50 quattro, for instance, typically achieves around 95 MPGe combined, slightly better than the EQB, but often at a higher price point and with a different driving dynamic. The Tesla Model Y Long Range, a perennial benchmark, boasts an impressive 123 MPGe combined, significantly surpassing the EQB in pure efficiency metrics. However, the EQB buyer isn’t necessarily just chasing the highest MPGe. They are drawn to the distinct Mercedes-Benz interior and exterior design language, the tactile quality of the materials, and the familiar user interface of the MBUX system.

While the EQB 300 4MATIC might not lead the pack in raw MPGe, its 87 MPGe is still a highly competitive figure that offers substantial savings over internal combustion alternatives, combined with the classic Mercedes luxury experience. Drivers seeking EQB MPG across all years will find the 2025 model a strong performer.

Tips to maximize efficiency

Gentle acceleration and deceleration are key to maximizing the EQB’s range. Abrupt inputs significantly drain the battery, whereas smooth driving allows the regenerative braking system to recover more energy more effectively. Using the Eco driving mode also fine-tunes accelerator response and climate control settings to prioritize efficiency, making it ideal for daily commutes where dynamic performance isn’t the primary concern. Pre-conditioning the cabin while the vehicle is still plugged in allows the EQB to use grid power for heating or cooling, rather than drawing energy from its battery. This is particularly effective in extreme weather conditions. Maintaining proper tire pressure is a simple yet crucial step; underinflated tires increase rolling resistance and reduce efficiency. Finally, avoid carrying unnecessary weight in the vehicle, as every extra pound requires more energy to move, impacting the EQB’s overall electric economy.
