Meet the 2025 GMC Sierra 2500HD: Heavy-Duty Excellence

Two Potent Drivetrain Options

The Sierra 2500HD offers two powerful and effective engine options, giving drivers a choice between gasoline and diesel power. The standard engine is a gasoline-powered 6.6-liter V8 that’s paired with an Allison 10-speed electronically controlled automatic transmission with overdrive, tow/haul mode, and auto grade braking. It produces 401 horsepower and 464 foot-pounds of torque, which is delivered to either a 2WD or 4WD drivetrain.

For drivers who prefer the smooth torque of a diesel engine, the Sierra 2500HD also offers a 6.6-liter Duramax turbo diesel V8 with a 3.42 rear axle ratio, engine block heater, exhaust brake, and an engine run-after feature for enhanced cooling. It is also mated to an Allison 10-speed automatic transmission and 2WD or 4WD drivetrain. The diesel powerplant churns out 470 horsepower and 975 foot-pounds of torque.

Heavy-Duty Payload and Towing Capability

The Sierra 2500HD puts its tremendous power to work with heavy-duty payload and towing capability. In the popular crew cab configuration, the 2500HD can carry up to six adults, and its 6.8-foot cargo bed offers 69.5 cubic feet of cargo volume and a maximum payload capacity of 4,081 pounds when properly equipped. The 2500HD also has standard cargo tie-downs and bed lighting that make towing simpler.

When the load outweighs the 2500HD’s onboard capacity, it has the towing power to get the job done. With the gas-powered V8, the maximum towing capacity of the 2500HD is 18,700 pounds when properly outfitted. When equipped with the Duramax turbo diesel and other available towing options, the Sierra 2500HD can tow up to 22,070 pounds.

Modern Safety and Infotainment Technology

With modern safety, driver assistance, and connectivity technology, the 2500HD can help drivers arrive safely and maintain connection at any job site. The standard safety features in the 2500HD include automatic emergency braking, following distance indicator, an HD rear vision camera, lane change alert with side blind zone alert, lane departure alert, front pedestrian braking, forward collision alert, and six airbags.

The infotainment and connectivity features considered standard in the 2500HD include Wi-Fi hotspot capability, a 6-speaker audio system, a 3.5-inch driver information center, the GMC Infotainment System with a 7-inch color touchscreen, wireless Android Auto and Apple CarPlay, and Bluetooth streaming.

The GMC Sierra 2500HD offers true heavy-duty excellence in a three-quarter-ton package, with powerful engine options, hard-working hauling capacity, and a robust lineup of premium features.
