The 2022 Mercedes-Benz EQB 300 4matic gets 101 MPGe combined, moving the compact electric SUV beyond just being an obligation and making it a real option for families who want to drive responsibly while still enjoying a luxury experience. This is about enjoying the comforts and prestige of a Mercedes-Benz while using less gas.

City and highway performance

The EQB 300 4matic’s EPA ratings show what its electric powertrain can do. The 104 MPGe city rating shows how well the regenerative braking system works in cities, capturing energy when you stop and start often. The 98 MPGe highway rating, while a bit lower, is still very efficient for long trips. These numbers indicate a car that’s great for city life, but also well-suited for longer road trips.

Annual fuel cost

The EPA estimates that it will cost $750 per year to power the 2022 Mercedes-Benz EQB 300 4matic. This is calculated assuming 15,000 miles of driving per year, a set split between city and highway driving, and the national average electricity cost. For drivers who usually pay much more for gasoline, this is a big saving and a real financial advantage of owning an EV. This calculation also doesn’t include possible savings from charging during off-peak hours, which can lower running costs even more.

Real-world expectations

EPA ratings give a standard for comparison, but actual MPGe can change based on how you drive, the temperature outside, and the type of roads you’re on. If you accelerate hard, use the climate control often, and drive on hills, efficiency will go down. But if you drive gently, pre-condition the cabin while plugged in, and use the car’s Eco mode, you can get close to or even better than the EPA estimates. The EQB’s “D Auto” recuperation mode adjusts regenerative braking based on traffic, and helps save energy while you drive. Most EQB drivers will find their real world MPGe settles somewhere close to the official figure.

How it compares

The EQB’s efficiency is similar to other electric SUVs in its class. For example, the Audi Q4 e-tron has an EPA-estimated 100 MPGe combined, while the Volvo XC40 Recharge is around 85 MPGe. The Tesla Model Y Long Range gets a slightly higher 122 MPGe. The EQB stands out because it has the luxury you expect from Mercedes-Benz and optional third-row seating, which is rare in this class. If you want the most range and efficiency possible, the Tesla might be better, but if you want a luxury experience in a smaller package, you’ll like the EQB’s balance. Compare EQB MPG across all years to the competition for a more complete picture.

Tips to maximize efficiency

Pre-condition the cabin while the vehicle is plugged in. This heats or cools the interior using grid power instead of the battery, preserving range, especially in extreme temperatures. Using the heated seats and steering wheel instead of the cabin heater can also save energy, as these localized heating elements are more efficient.

Use the EQB’s regenerative braking system well. Think ahead and ease off the accelerator early to get the most energy back. Try out the different regenerative braking modes to find the one that works best for you.

Keep your tires properly inflated. This reduces rolling resistance and improves how efficiently the car drives. Check the sticker on the driver’s side doorjamb for the correct pressure. When it’s time to replace your tires, think about getting low-rolling-resistance tires. For all Mercedes Benz fuel economy data, be sure to check out our related pages.

Drive smoothly and don’t accelerate or brake hard. Quick changes in speed use more energy. Keep a steady pace and watch the traffic to avoid wasting energy.

Reduce how aerodynamic drag. Take off anything you don’t need from the roof rack or cargo carrier, because this can really increase drag and lower efficiency, especially at highway speeds. If you often need to carry large items, think about using a more aerodynamic cargo carrier.
