The 2025 Mercedes-Benz GLC is a petrol SUV with AWD and seating for 5. It belongs to the X254 generation. The 300 4MATIC is the version described here, and the figures below refer to that configuration unless noted otherwise.
Performance
The featured 300 4MATIC version develops 258 hp and 400 Nm (295 lb-ft) of torque. Its listed 0-100 km/h time is 6.2 seconds, which is decisively quick for everyday road use. Top speed is listed at 240 km/h (149 mph). Its power output is about 6% below the peer average. Its 0-100 km/h time is about 14% quicker than 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 8.4 L/100km. Fuel-tank capacity is 62.0 litres (16.4 US gallons). Recorded CO2 emissions are 191 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 4,716 mm (185.7 in) in length, 1,890 mm (74.4 in) in width, and 1,640 mm (64.6 in) in height, while the wheelbase measures 2,888 mm (113.7 in). Cargo capacity is listed at 600 litres (21.2 cu ft), expanding to 1,640 litres (57.9 cu ft) with the rear seats folded. The cabin is configured for 5 occupants. Listed curb weight is 1,895 kg (4,178 lb). The recorded braked towing capacity is 2,400 kg (5,291 lb). That cargo volume is about 5% above 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 GLC is strongest on acceleration and towing capacity. 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.
