84 MPG combined is a stellar figure, but it’s crucial to recognize what the 2016 Mercedes-Benz B250e is: an all-electric hatchback designed for urban commuting and short-range trips. It’s a city car that sips electrons instead of gasoline, appealing to a specific buyer who prioritizes lower fuel costs and low running costs above all else. The B250e isn’t about setting land speed records, but rather about quietly and efficiently navigating congested streets.

City and highway performance

The B250e’s EPA ratings highlight its urban strengths. An impressive 85 MPG in the city reflects the regenerative braking system’s effectiveness in stop-and-go traffic, recapturing energy and extending the car’s range. The 82 MPG highway rating, though still excellent, underscores the inherent limitations of electric vehicles at higher speeds, where aerodynamic drag becomes a significant factor. For the B250e driver, this means maximizing efficiency by sticking to reasonable speeds on the open road and using the immediate torque for confident merging and passing maneuvers within its designed operating parameters.

Annual fuel cost

The EPA estimates an annual fuel cost of just $900 for the 2016 Mercedes-Benz B250e. This calculation is based on driving 15,000 miles per year, with a mix of city and highway driving, at the national average electricity prices when the vehicle was new. The key here is the electricity cost. Unlike gasoline vehicles susceptible to volatile pump prices, the B250e driver enjoys significantly more stable and predictable energy expenses. Charging at home overnight, particularly during off-peak hours, can further reduce these costs, making this all-electric hatchback an incredibly economical choice for daily commuting.

Real-world expectations

While the EPA provides a standardized benchmark, real-world fuel economy can vary depending on several factors. Driving style, ambient temperature, terrain, and even the use of air conditioning or heating can all impact the B250e’s actual mileage. Aggressive acceleration and high-speed driving will deplete the battery faster, while gentle acceleration and anticipatory braking can extend the range. Pre-conditioning the cabin while the car is plugged in can also help preserve battery life, ensuring that the energy is used for propulsion rather than climate control. As with any electric vehicle, monitoring energy consumption and a conscious effort to optimize driving habits are essential for achieving the best possible mileage.

How it compares

When considering all-electric alternatives from 2016, the B250e faced competition such as the BMW i3 and the Nissan LEAF. The BMW i3, with its quirky styling and optional range extender, achieved approximately 124 MPGe combined. The Nissan LEAF, a more mainstream electric hatchback, was rated around 114 MPGe. While on paper these numbers appear higher than the B250e’s 84 MPG, it’s important to consider the B250e’s brand. Buyers of the B250e were often drawn to the Mercedes-Benz image, the higher quality interior compared to the LEAF, and the overall driving refinement expected of a Mercedes-Benz product. They were willing to accept slightly lower efficiency for a taste of German luxury and engineering in an electric package. View all Mercedes Benz fuel economy data.

Tips to maximize efficiency

Use the B250e’s regenerative braking system. Anticipate stops and coast whenever possible, allowing the system to recapture energy and extend your range. Avoid abrupt acceleration and braking, as these actions consume more energy. Smooth, consistent driving is the key to maximizing efficiency.

Pre-condition the cabin while the car is plugged in. Heating and cooling the interior while still connected to the charging station prevents the battery from being drained to regulate the temperature when you start driving. This is especially useful in extremely hot or cold weather, as it helps maintain optimal battery performance.

Monitor your tire pressure regularly. Under-inflated tires increase rolling resistance, which in turn reduces fuel efficiency. Maintaining the recommended tire pressure ensures optimal performance and extends the life of your tires, ultimately saving you money and reducing energy consumption.

Optimize your route to avoid unnecessary stops and starts. Planning your trips in advance and choosing routes with less traffic congestion can reduce energy consumption and extend your range. Consider using the B250e’s navigation system to find the most efficient route, taking into account real-time traffic conditions.
