The 2025 GMC Sierra 1500 is a petrol pickup with RWD and seating for 6. It belongs to the Gen 4 LCI generation. The SLE 2.7L Turbo is the version described here, and the figures below refer to that configuration unless noted otherwise.
Performance
The featured SLE 2.7L Turbo version develops 310 hp and 583 Nm (430 lb-ft) of torque. Its listed 0-100 km/h time is 6.5 seconds, which is decisively quick for everyday road use. Top speed is listed at 180 km/h (112 mph). Its power output is about 11% 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 10.2 L/100km. Fuel-tank capacity is 91.0 litres (24.0 US gallons). Recorded CO2 emissions are 233 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 5,887 mm (231.8 in) in length, 2,062 mm (81.2 in) in width, and 1,917 mm (75.5 in) in height, while the wheelbase measures 3,745 mm (147.4 in). The cabin is configured for 6 occupants. Listed curb weight is 2,340 kg (5,159 lb). The recorded braked towing capacity is 4,173 kg (9,200 lb). 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 SLE 2.7L Turbo and Denali 6.2L V8. Across the range, the specifications span 310 hp to 420 hp and 6.0 s to 6.5 s, while listed starting prices run from $44,900-$65,200. 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 pickup models from the same period, the 2025 GMC Sierra 1500 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.
