The 2024 GMC Sierra 1500 is a petrol pickup with AWD and seating for 6. It belongs to the Gen 4 LCI generation. The AT4 3.0L Diesel is the version described here, and the figures below refer to that configuration unless noted otherwise.
Performance
The featured AT4 3.0L Diesel version develops 305 hp and 620 Nm (457 lb-ft) of torque. Its listed 0-100 km/h time is 7.0 seconds, which is responsive rather than outright performance-focused. Top speed is listed at 180 km/h (112 mph). Its power output is about 15% below the peer average. Its 0-100 km/h time is about 9% slower 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 91.0 litres (24.0 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 5,887 mm (231.8 in) in length, 2,062 mm (81.2 in) in width, and 1,930 mm (76.0 in) in height, while the wheelbase measures 3,745 mm (147.4 in). The cabin is configured for 6 occupants. Listed curb weight is 2,470 kg (5,445 lb). The recorded braked towing capacity is 5,987 kg (13,199 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.
In perspective
Compared with nearby petrol pickup models from the same period, the 2024 GMC Sierra 1500 is strongest on towing capacity, while price 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.
