27 MPG combined won’t win any hypermiling awards, but for the 2024 Mercedes-Benz GLB250 4matic, equipped with its eager 2.0L turbocharged 4-cylinder, it’s a respectable figure. This isn’t a small hatchback; it’s a stylish, somewhat boxy, and surprisingly practical small SUV. It offers an optional third row, which, while tight, expands its appeal to families who occasionally need to carry more than five passengers. The GLB250 caters to a specific buyer: someone who appreciates the prestige of the Mercedes-Benz brand, needs the versatility of a small SUV, and prioritizes space efficiency over outright fuel savings.

City and highway performance

The EPA estimates the GLB250 4matic achieves 24 MPG in the city and 32 MPG on the highway. The city figure reflects the demands of stop-and-go traffic, where the turbocharger is constantly spooling up and down, and the engine spends more time idling. The highway number demonstrates the engine’s efficiency at a steady cruise. The 8-speed automatic transmission plays a crucial role, keeping the engine in its optimal power band, whether you’re navigating urban streets or covering long distances on the open road.

Annual fuel cost

The EPA estimates that the annual fuel cost for the 2024 Mercedes-Benz GLB250 4matic is $2,150. This figure is based on driving 15,000 miles per year, with 55% of that mileage occurring in the city and 45% on the highway, using national average fuel prices. Individual fuel costs will vary depending on driving habits, location, and current gasoline prices, but this provides a standardized benchmark for comparison. If you primarily drive in the city, expect to spend slightly more; conversely, if your driving is primarily highway miles, you may spend less.

Real-world expectations

While the EPA estimates offer a good starting point, real-world fuel economy can vary significantly. Factors like driving style, terrain, and weather conditions all play a role. Aggressive acceleration, frequent braking, and driving in hilly areas will all negatively impact fuel efficiency. Conversely, smooth, consistent driving, particularly on flat terrain, will help you achieve or even exceed the EPA estimates. Keep an eye on tire pressure as well; properly inflated tires reduce rolling resistance and improve fuel economy.

How it compares

In the competitive landscape of small luxury SUVs, the GLB250 4matic’s fuel economy is generally competitive. The BMW X1 xDrive28i, a direct rival, achieves a combined 28 MPG. The Audi Q3 45 Premium Quattro sits closer to 25 MPG combined. The Volvo XC40 B5 AWD manages around 26 MPG. These differences, while seemingly small, can add up over the life of the vehicle. The GLB250’s appeal isn’t solely based on fuel efficiency; it lies in its unique combination of Mercedes-Benz luxury, clever interior packaging, and available third-row seating, which sets it apart from many of its competitors.

Tips to maximize efficiency

Use the “Eco” driving mode. The GLB250 4matic offers different driving modes that tailor the engine and transmission response to prioritize fuel efficiency. Eco mode will typically soften throttle response, encourage earlier upshifts, and even coast when possible, all contributing to improved MPG.

Maintain a smooth and steady driving style. Avoid aggressive acceleration and hard braking. Anticipate traffic flow and maintain a consistent speed whenever possible. This reduces unnecessary fuel consumption and wear on the vehicle.

Minimize idling. If you’re stopped for more than a minute or two, it’s generally more fuel-efficient to turn off the engine rather than let it idle. Modern engines are designed to start and stop frequently without causing excessive wear.

Ensure proper tire inflation. Check your tire pressure regularly and inflate your tires to the recommended pressure listed on the doorjamb. Underinflated tires increase rolling resistance and reduce fuel economy.

Keep up with scheduled maintenance. Regular oil changes, air filter replacements, and other routine maintenance tasks ensure that your engine is running at peak efficiency. A well-maintained engine consumes less fuel.
