The 2025 GMC Terrain is a petrol SUV with AWD and seating for 5. It belongs to the Gen 3 generation. The Denali is the version described here, and the figures below refer to that configuration unless noted otherwise.
Performance
The featured Denali version develops 252 hp and 370 Nm (273 lb-ft) of torque. Its listed 0-100 km/h time is 7.5 seconds, which is responsive rather than outright performance-focused. Top speed is listed at 195 km/h (121 mph). Its power output is about 8% 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 9.0 L/100km. Fuel-tank capacity is 60.0 litres (15.9 US gallons). Recorded CO2 emissions are 206 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 4,658 mm (183.4 in) in length, 1,890 mm (74.4 in) in width, and 1,724 mm (67.9 in) in height, while the wheelbase measures 2,744 mm (108.0 in). Cargo capacity is listed at 648 litres (22.9 cu ft), expanding to 1,810 litres (63.9 cu ft) with the rear seats folded. The cabin is configured for 5 occupants. Listed curb weight is 1,730 kg (3,814 lb). The recorded braked towing capacity is 1,588 kg (3,501 lb). That cargo volume is about 14% 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.
The model range
The recorded line-up consists of AT4 and Denali. Across the range, the specifications span 252 hp and 7.5 s, while listed starting prices run from $38,400-$42,200. Drivetrain, battery or engine choice, wheels and market equipment can all change the final figures, so the version table should be used when choosing between them.
In perspective
Compared with nearby petrol SUV models from the same period, the 2025 GMC Terrain is strongest on price and cargo capacity, while towing capacity and power 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.
