25 MPG combined is a reasonable figure for the 2022 Mercedes-Benz GLB250 4matic, reflecting a practical balance between its size, good cargo space, and the all-wheel drive system. It’s not a fuel-sipping hybrid, nor is it trying to be. It’s a premium subcompact SUV designed for city drivers who occasionally need to haul more than groceries and want reassurance in bad weather, all wrapped in the Mercedes-Benz brand.

City and highway performance

The EPA estimates 22 MPG in the city and 30 MPG on the highway for the GLB250 4matic. The city figure reflects the demands of stop-and-go traffic, where the 2.0L turbocharged four-cylinder engine is constantly accelerating from a standstill. The highway number demonstrates that, even with all-wheel drive, the GLB250 can achieve respectable fuel economy when cruising at consistent speeds. The eight-speed automatic transmission helps with this, keeping the engine in its most efficient rev range at higher speeds. While some may want higher highway numbers, 30 MPG offers a good mix of confidence and comfort.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2022 Mercedes-Benz GLB250 4matic is $2,300. This is based on driving 15,000 miles per year and using national average fuel prices. This is just an estimate, your actual fuel costs will depend on your driving, the type of fuel you use, and local fuel prices. Someone who drives mainly in the city and accelerates quickly will likely spend more, while a driver who mainly takes long highway trips and drives carefully may see a lower annual fuel bill.

Real-world expectations

EPA estimates are a helpful benchmark, but real-world fuel economy can vary. GLB250 4matic owners often report numbers close to the EPA’s estimates, but individual results can differ. Your MPG can be impacted by factors like driving style, traffic, and even tire pressure. Consistent hard acceleration, frequent short trips, and neglecting maintenance will likely reduce fuel efficiency. On the other hand, smooth driving, regular servicing, and properly inflated tires can help you achieve or even exceed the EPA’s figures. Visit FuelEconomyHub.com to see GLB250 MPG across all years.

How it compares

The GLB250 4matic is in a competitive segment where fuel economy is considered, but not always first. The BMW X1 xDrive28i, a direct competitor, gets about 25 MPG combined. The Audi Q3 45 TFSI quattro also mirrors that combined number. While these vehicles offer similar levels of luxury and performance, those wanting to save the most on gas might consider something like the Lexus UX 250h, a hybrid SUV that gets around 42 MPG combined. However, the UX has less cargo space and less performance to achieve that efficiency. The GLB250 4matic strikes a reasonable balance, and its fuel economy is acceptable if you want space, all-weather confidence, and the Mercedes-Benz brand. See all Mercedes Benz fuel economy data.

Tips to maximize efficiency

Use the GLB250’s driving modes. “Eco” mode will change the throttle and shift points to prioritize fuel efficiency. Even a small change in driving style can make a difference over time.

Make sure your tires are properly inflated. Underinflated tires increase rolling resistance, which reduces fuel economy. Check your tire pressure often and inflate them to the pressure recommended on the sticker inside the driver’s side door.

Avoid unnecessary idling. If you’re stopped for more than a minute or two, turn off the engine. Modern engines are designed to restart quickly and efficiently, and idling wastes fuel and increases emissions.

Keep up with routine maintenance. A well-maintained engine runs more efficiently. Follow the manufacturer’s maintenance schedule, including oil changes, air filter replacements, and spark plug replacements.

Reduce aerodynamic drag. Remove any unneeded items from the roof rack or cargo carrier when not in use. These items increase aerodynamic drag, which reduces fuel economy, especially at highway speeds.
