• The 2025 GMC Sierra 2500HD AT4X Crew Cab is built for drivers who need serious capability without giving up comfort. Finished in Summit White with an Obsidian Rush interior, this heavy-duty truck pairs a bold off-road-focused presence with the roomy crew cab layout that makes long days and full passenger loads easy to manage.Under the hood is the Duramax 6.6L turbo-diesel V8, rated at 470 horsepower and 975 lb-ft of torque, matched to a smooth-shifting automatic transmission. Four-wheel drive puts that power to the ground whether you're towing a heavy trailer, hauling a full bed, or heading well past the end of the pavement.As the AT4X trim, this Sierra 2500HD sits at the top of the off-road lineup, blending rugged hardware with the premium finishes GMC is known for. The diesel powertrain also delivers the kind of low-end pulling strength and highway confidence that make it a strong choice for work and recreation alike.If a capable, well-equipped heavy-duty truck is on your list, this one is worth a closer look.
