The 2024 Mercedes-Benz EQB 250 Plus achieves a combined fuel economy rating of 107 MPGe (miles per gallon equivalent), a major selling point for this compact, all-electric SUV. This number reflects the EQB 250 Plus’s core mission: to provide a practical, luxurious, and relatively affordable entry point into electric Mercedes-Benz ownership. The EQB 250 Plus is designed for urban professionals, young families, and anyone seeking a premium EV that can handle daily commutes and occasional longer trips without constantly needing a charge.

City and highway performance

The EPA breaks down the 107 MPGe combined rating into 114 MPGe in the city and 100 MPGe on the highway. This difference highlights the EQB 250 Plus’s strength in stop-and-go traffic. Electric vehicles generally excel in city environments due to regenerative braking, which captures energy during deceleration and feeds it back into the battery. This significantly reduces energy consumption compared to combustion engines that lose energy to heat during braking. Constant speeds on the highway minimize regenerative braking opportunities, so efficiency dips slightly. Still, 100 MPGe is an impressive number likely to make gasoline vehicle owners jealous of the money saved by going electric. Higher city MPGe is relevant to prospective buyers who do most of their driving in urban environments. For those who consistently log longer highway miles, understanding that slight drop in efficiency is key to managing range expectations.

Annual fuel cost

According to the EPA, the annual fuel cost for the 2024 Mercedes-Benz EQB 250 Plus is estimated at $700. This figure is based on driving 15,000 miles per year and national average electricity prices. Your own electricity costs might be higher or lower depending on your location and charging habits, of course. Charging at home during off-peak hours will drastically reduce the cost per mile. The EPA’s $700 estimate provides a standardized benchmark for comparing the EQB 250 Plus to other vehicles, both electric and gasoline-powered. Even with potentially higher personal electricity costs, it’s reasonable to expect significant savings over a comparable gasoline vehicle.

Real-world expectations

EPA numbers provide a useful baseline, but real-world fuel economy can vary based on several factors. Driving style, ambient temperature, terrain, and cargo weight all play a role. Aggressive acceleration and high speeds will drain the battery faster, while gentler driving and pre-conditioning the cabin temperature while the car is plugged in can improve efficiency. Cold weather can also reduce the range of electric vehicles, as the battery’s chemical processes slow down in lower temperatures. The EQB’s energy management system and selectable drive modes help mitigate these effects. Drivers can select “Eco” mode to prioritize efficiency, limiting power output and adjusting climate control settings to conserve energy. The vast majority of EQB 250 Plus drivers will likely get very close to the official ratings, as the vehicle isn’t likely to be used for heavy hauling or extreme driving.

How it compares

The Mercedes-Benz EQB 250 Plus competes in a crowded segment of electric SUVs. The Volvo XC40 Recharge, for instance, is rated at 118 MPGe combined, making it superficially more efficient than the EQB 250 Plus. The Tesla Model Y Long Range achieves 122 MPGe combined and often sets the standard for electric vehicle efficiency in this segment. But the EQB offers a luxury experience and a more traditional SUV design that appeals to buyers who aren’t necessarily chasing the absolute top spot when evaluating all all Mercedes Benz fuel economy data. The Kia EV6 offers a combination of performance and efficiency, with the Long Range RWD model achieving 117 MPGe combined. The Hyundai IONIQ 5 Long Range RWD matches the Kia EV6’s efficiency for those prioritizing ultimate range. Choosing between these options often comes down to brand preference, styling, and specific feature sets. Be sure to check out the EQB MPG across all years to see how the model holds up over time.

Tips to maximize efficiency

The EQB 250 Plus has regenerative braking, which harvests energy when you lift off the accelerator. Experiment with the different levels of regeneration to find a setting that suits your driving style. Maximizing regenerative braking can significantly improve your overall efficiency, especially in stop-and-go traffic.

Pre-conditioning the cabin while the EQB 250 Plus is plugged in can save battery power. Instead of using battery energy to heat or cool the car when you’re ready to drive, pre-conditioning allows you to start your journey with a comfortable cabin temperature without impacting range.

Use the EQB’s Eco driving mode in appropriate situations. Eco mode limits power output and adjusts other settings to maximize efficiency. While it might not be ideal for spirited driving, Eco mode is perfect for city commutes and highway cruising when range is a priority.

Keep your tires properly inflated. Underinflated tires increase rolling resistance, which reduces efficiency. Check your tire pressure regularly and inflate them to the recommended levels listed on the doorjamb sticker.

Minimize unnecessary weight. Carrying extra cargo can reduce efficiency, even in an electric vehicle. Remove any unnecessary items from your car to lighten the load and improve your range.
