26 MPG combined is a reasonable figure for the 2020 Mercedes-Benz GLB250 4matic, a versatile subcompact SUV that prioritizes space and refinement over extreme fuel efficiency. This isn’t trying to compete with a Prius; it’s a small family hauler that delivers a luxury experience while offering the practicality of available third-row seating (though best suited for smaller passengers). Owners accept the GLB250’s fuel economy because they value its unique blend of Mercedes-Benz brand recognition, cargo capacity, and maneuverability in urban environments.

City and highway performance

The EPA estimates the GLB250 4matic achieves 23 MPG in the city and 31 MPG on the highway. The city figure reflects stop-and-go driving, where the GLB’s turbocharged 2.0L engine works harder to get the car moving. The eight-speed automatic transmission (AM8) does its best to keep the engine in its optimal range, but city traffic takes its toll. On the highway, the GLB250 4matic settles into a more efficient cruising speed.

The 31 MPG rating is achievable on long road trips, especially if you maintain a steady speed and avoid aggressive acceleration. The 4matic all-wheel-drive system provides added traction and stability in inclement weather, but it does slightly reduce fuel economy compared to the front-wheel-drive GLB250.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2020 Mercedes-Benz GLB250 4matic at $2,250. This figure is based on driving 15,000 miles per year and using national average fuel prices. This is just an estimate, and your actual fuel costs may vary depending on your driving habits, the type of fuel you use, and where you live.

For example, if you primarily drive in the city and accelerate quickly, you can expect to spend more than $2,250 per year on fuel. If you do a lot of highway driving and are mindful of your speed and acceleration, you could potentially spend less. To see GLB250 MPG across all years, you can browse historical data.

Real-world expectations

While the EPA estimates provide a baseline, your actual fuel economy in the GLB250 4matic will largely depend on your driving style and environment. Owners who prioritize fuel efficiency and spend a lot of time on the highway are likely to get close to the EPA’s 31 MPG highway rating. However, those who frequently drive in stop-and-go traffic or accelerate rapidly might see numbers closer to the 23 MPG city rating, or even lower.

Factors like tire pressure, vehicle maintenance, and even the weight of cargo you are carrying can also affect your fuel economy.

How it compares

In the competitive subcompact luxury SUV segment, fuel economy varies. The BMW X1 xDrive28i manages a combined 27 MPG, slightly better than the GLB250 4matic. The Audi Q3 45 TFSI quattro also achieves 25 MPG combined, placing it in a similar range. The Volvo XC40 T5 AWD offers 26 MPG combined, matching the GLB250. However, vehicles like the Lexus UX 250h, a hybrid, achieve significantly better fuel economy, boasting 42 MPG combined.

Buyers choosing the GLB250 aren’t solely focused on maximizing MPG; they value the Mercedes-Benz brand, interior space (including the optional third row), and overall driving experience, all of which come with tradeoffs.

Tips to maximize efficiency

Maintaining proper tire pressure is one of the simplest ways to improve fuel economy in the GLB250 4matic. Underinflated tires create more rolling resistance, forcing the engine to work harder. Check your tire pressure regularly and inflate them to the recommended levels listed on the doorjamb sticker.

Avoid aggressive acceleration and braking. The GLB250’s turbocharged engine is responsive, but accelerating quickly consumes more fuel. Smooth, gradual acceleration and anticipating traffic conditions can help you conserve fuel.

Reduce unnecessary weight. Carrying heavy items in your GLB250 will reduce fuel economy. Remove any items you don’t need from the cargo area and passenger compartment to minimize the load on the engine.

Consider using the ECO drive mode. The GLB250’s driving mode selector allows you to choose between different driving modes, including ECO. This mode optimizes the engine and transmission settings for maximum fuel efficiency.

Regular maintenance is essential for good fuel economy. Keep your GLB250 in good condition by following the recommended maintenance schedule, including oil changes, filter replacements, and tune-ups. A well-maintained engine will run more efficiently and consume less fuel.
