The 2025 Mercedes-Benz GLS is a petrol SUV with AWD and seating for 7. It belongs to the X167 LCI generation. The GLS 450 4MATIC is the version described here, and the figures below refer to that configuration unless noted otherwise.
Performance
The featured GLS 450 4MATIC version develops 362 hp and 500 Nm (369 lb-ft) of torque. Its listed 0-100 km/h time is 5.9 seconds, which is decisively quick for everyday road use. Top speed is listed at 245 km/h (152 mph). Its power output is about 32% above the peer average. Its 0-100 km/h time is about 19% 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 10.6 L/100km. Fuel-tank capacity is 90.0 litres (23.8 US gallons). Recorded CO2 emissions are 242 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 5,207 mm (205.0 in) in length, 2,030 mm (79.9 in) in width, and 1,823 mm (71.8 in) in height, while the wheelbase measures 3,135 mm (123.4 in). Cargo capacity is listed at 680 litres (24.0 cu ft), expanding to 2,400 litres (84.8 cu ft) with the rear seats folded. The cabin is configured for 7 occupants. Listed curb weight is 2,420 kg (5,335 lb). The recorded braked towing capacity is 3,500 kg (7,716 lb). That cargo volume is about 19% 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 GLS is strongest on towing capacity and power, while price stands 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.
