The 2025 Mercedes-Benz GLB is a petrol SUV with AWD and seating for 7. It belongs to the X247 LCI generation. The 250 4MATIC is the version described here, and the figures below refer to that configuration unless noted otherwise.
Performance
The featured 250 4MATIC version develops 221 hp and 350 Nm (258 lb-ft) of torque. Its listed 0-100 km/h time is 6.9 seconds, which is responsive rather than outright performance-focused. Top speed is listed at 236 km/h (147 mph). Its power output is about 19% below the peer average. Its acceleration is close to the peer average. The figures establish its straight-line performance on paper, but they do not substitute for measured braking, handling or ride-quality tests.
Fuel economy and range
The listed fuel consumption is 8.1 L/100km. Fuel-tank capacity is 51.0 litres (13.5 US gallons). Recorded CO2 emissions are 185 g/km. Consumption, emissions and range can be measured under different regional procedures, so like-for-like comparisons should use the same market and test cycle.
Dimensions and practicality
Its exterior dimensions are 4,634 mm (182.4 in) in length, 1,834 mm (72.2 in) in width, and 1,659 mm (65.3 in) in height, while the wheelbase measures 2,829 mm (111.4 in). Cargo capacity is listed at 500 litres (17.7 cu ft), expanding to 1,680 litres (59.3 cu ft) with the rear seats folded. The cabin is configured for 7 occupants. Listed curb weight is 1,650 kg (3,638 lb). The recorded braked towing capacity is 1,800 kg (3,968 lb). That cargo volume is about 12% below the peer average. The measurements are useful for comparison, although seat comfort, access and the shape of the load area still need to be judged in person.
In perspective
Compared with nearby petrol SUV models from the same period, the 2025 Mercedes-Benz GLB is strongest on price, while power and towing capacity stand out as the principal numerical compromise. That conclusion is drawn from the recorded specifications rather than a road test. A final choice should also account for local pricing, equipment, comfort and a test drive.
