2020 Mercedes-Benz GLB-Class fuel economy by version
EPA city/highway/combined estimates for each engine, transmission and drive combination. Annual fuel cost is EPA's estimate for 15,000 miles a year (55% city, 45% highway) at EPA's current fuel-price assumptions; your cost will vary.
Source: FuelEconomy.gov (U.S. DOE and EPA), file dated Sep 29, 2026. Each version links to its FuelEconomy.gov record.
EPA estimates come from standardized lab tests so cars can be compared fairly; real-world mileage depends on speed, weather, load, tires and driving style.
2020 Mercedes-Benz GLB-Class crash-test ratings
NHTSA 5-Star Safety Ratings for the tested versions. More stars mean a lower chance of serious injury in that type of crash. Rollover risk is NHTSA's estimated chance of rolling over in a single-vehicle crash.
Source: NHTSA 5-Star Safety Ratings (New Car Assessment Program), checked Oct 26, 2026.
Star ratings compare vehicles of similar size and weight; a frontal rating for a large pickup is not directly comparable with one for a small car.
