The 2023 Mercedes-Benz GLB250, with its EPA-estimated 27 MPG combined, is acceptable for its target audience. It’s chosen for its Mercedes-Benz brand, flexible interior, and better driving experience compared to mainstream compact SUVs, not necessarily for excellent fuel economy. Families who want space, technology, and a premium badge are okay with fuel economy that’s respectable but not groundbreaking.

City and highway performance

The GLB250 gets an EPA-estimated 24 MPG in the city and 32 MPG on the highway. The city figure reflects the stop-and-go driving many GLB250 drivers experience when driving kids to school, running errands, and navigating cities. The highway figure, while decent, could be better. The GLB’s boxy shape and standard all-wheel drive (optional on the base model) create some aerodynamic drag at higher speeds. The 2.0L turbocharged engine and smooth-shifting 8-speed automatic transmission (AM8) work well to provide acceptable efficiency across different driving conditions. For more information, you can see GLB250 MPG across all years.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 Mercedes-Benz GLB250 at $2,150. This is based on driving 15,000 miles per year, using the national average fuel price when calculated. Your actual fuel expenses will depend on your driving, location, and fuel prices. The $2,150 figure gives a standard to compare the GLB250’s fuel costs to other vehicles in its class. This number is helpful when budgeting for vehicle ownership costs.

Real-world expectations

EPA estimates are a starting point, but real-world fuel economy varies. GLB250 drivers who like quick acceleration or often carry passengers and cargo might see numbers closer to the low 20s in mixed driving. Drivers who drive conservatively and mainly drive on the highway might get numbers closer to, or slightly above, the EPA’s 32 MPG estimate. Tire pressure, temperature, and air conditioning also matter. The GLB250’s computer shows real-time and average fuel data, letting drivers track their efficiency and change their driving.

How it compares

The GLB250’s fuel economy competes in the compact luxury SUV segment, but there are differences. The BMW X1 xDrive28i has a similar EPA combined rating of 28 MPG. The Audi Q3, depending on the trim, gets around 25 MPG combined. The Lexus UX, while smaller, offers much better fuel economy in its hybrid version, exceeding 40 MPG combined. For those considering the Mercedes-Benz brand, all Mercedes Benz fuel economy data shows a range of options with varying MPGs. Ultimately, the GLB250 buyer accepts its fuel economy as part of a package that includes luxury features, advanced technology, and a third-row seat option, which many competitors don’t have.

Tips to maximize efficiency

Use the GLB250’s selectable drive modes. “Eco” mode will change the throttle and shift points to prioritize fuel efficiency, for smoother acceleration and earlier upshifts. This mode works well during slow city driving.

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

Reduce unnecessary weight. Extra cargo in the GLB250 adds weight, increasing fuel use. Remove unneeded items from the vehicle to reduce the load on the engine.

Avoid fast acceleration and braking. Gentle acceleration and smooth braking save fuel. Look ahead and keep a steady speed when you can, rather than constantly accelerating and decelerating.

Think about using cruise control on the highway. Keeping a consistent speed on the highway with cruise control helps optimize fuel efficiency. Pay attention to traffic and don’t use cruise control in hilly or congested areas.
