The 2023 Mercedes-Benz GLB250 4matic with its 2.0L 4-cylinder engine should get around 25 MPG combined. It’s not outstanding fuel economy, but it’s acceptable for a small, premium SUV that prioritizes versatility and refined driving over pure efficiency. The GLB250 is for buyers who need a compact size but also want the option of a surprisingly usable third row (though best for children) and the confidence of 4MATIC all-wheel drive. Fuel economy is a consideration, but other practical features are often more important.
City and highway MPG
The EPA estimates the 2023 GLB250 4MATIC achieves 22 MPG in the city and 30 MPG on the highway. The city figure reflects the demands of stop-and-go driving, where the GLB’s turbocharger works to provide adequate low-end torque. The 8-speed automatic transmission keeps the engine in its optimal range. On the highway, the GLB250 is great, delivering a comfortable and fuel-efficient cruising experience. The tall gearing lets the engine run at lower RPMs at higher speeds, contributing to the impressive 30 MPG rating.
Annual fuel cost
The EPA estimates the annual fuel cost for the 2023 Mercedes-Benz GLB250 4matic is $2,300. This is based on driving 15,000 miles per year and using national average fuel prices. What you actually spend will depend on your driving habits, local fuel prices, and the type of fuel used. The GLB250 doesn’t require premium fuel, but using it may slightly improve performance and fuel economy.
Real-world MPG
While the EPA estimates offer a standardized comparison, real-world fuel economy often differs. GLB250 owners often report numbers close to the EPA’s estimates. Many see slightly lower numbers in city driving and might exceed 30 MPG on long highway trips. Aggressive driving, frequent use of Sport mode, and carrying extra weight can all hurt fuel economy. Using a smooth driving style and Eco mode can help maximize MPG. You can browse GLB250 MPG across all years to get a fuller sense of how the car performs.
How it compares
The GLB250’s fuel economy is competitive within its class, but other choices exist. The BMW X1 xDrive28i, a direct competitor, gets an EPA-estimated 28 MPG combined. The Audi Q3 45 TFSI quattro gets about 25 MPG combined. The Volvo XC40 B5 AWD has a combined rating of 26 MPG. These small MPG differences probably won’t be the only factor for most buyers. They might care more about brand, features, and how the car drives. See all Mercedes Benz fuel economy data for a full comparison.
Tips to maximize MPG
The Eco mode softens the accelerator and sets the transmission to shift for maximum fuel efficiency. It works well for city driving and highway cruising. Leaving the vehicle in Comfort or Sport mode for more spirited driving will reduce your MPG.
Check your tire pressure often. Underinflated tires increase rolling resistance, which uses more fuel. Check the sticker on the driver’s side doorjamb of the GLB250 for the correct tire pressure.
Don’t idle too long. If you expect to be stopped for more than a minute, turn off the engine. Modern engines restart fast, and avoiding idling can save fuel.
Don’t drive aggressively. Accelerating quickly and braking hard uses more fuel than smooth driving. Watch traffic and keep a steady speed to save gas.
