The 2025 GMC Sierra HD is a brawny truck that delivers rugged power while still providing a comfortable interior equipped with smart technology. If you need serious hauling capability but don’t want to compromise on interior features, take a look at the 2025 Sierra HD at your local GMC dealership.
1: Powerful Engine for All Adventures
There are seven different trims for the 2025 Sierra HD for both the 2500 and the 3500. Every trim level includes the same powerful 6.6-liter V8 gasoline engine as standard. This delivers 401 horsepower and 464 lb-ft of torque, so there’s no shortage of muscle for any work activity or weekend adventure. A 10-speed automatic transmission completes the set-up, providing smooth shifts and control, even with heavy loads.
For those looking for even more brute strength, it’s possible to upgrade to a 6.6-liter Duramax Turbo-diesel V8 engine. This increases the capacity to 470 horsepower and 975 lb-ft of torque. For many drivers, the standard gasoline engine provides more than enough power, but for extra-heavy loads or regular weighty hauling, the available diesel engine offers a great alternative.
2: Impressive Towing Capacity
If towing is a priority, then there’s plenty on offer with the 2025 Sierra HD. When equipped with the gasoline engine, the 2500 is capable of towing up to 16,500 lbs when using a gooseneck, while the 3500 can haul a mighty 19,000 lbs. Every model comes with a trailering package as standard, including a trailer brake controller and integrated trailering mirrors. This means you can start towing as soon as the wheels hit the road with no need to upgrade first.
The diesel engine ramps up the towing capability even further on the Sierra HD. The 2500 model can tow up to 22,500 lbs while the 3500 has the capacity to pull a blistering 36,000 lbs when configured with twin rear wheels and a gooseneck.
3: Smart Connectivity as Standard
Even on the entry-level trim, there’s an impressive technical specification included as standard. A 7-inch touchscreen infotainment system ensures that navigation, maps, and media are never more than a finger-swipe away. The system is also compatible with Apple CarPlay and Android Auto, giving you access to all your favorite apps without needing to plug in.
4: Best-in-Class Cargo Space
GMC understands that a good truck needs plenty of cargo space, which is why they’ve fitted the Sierra HD with a best-in-class capacity. A standard bed offers 69.5 cubic feet that can be extended to 83.5 cubic feet with a long bed configuration. As well as being bigger, the cargo box on the Sierra HD also offers robustness with a reinforced bed manufactured from high-strength steel plus tie-down hooks to secure heavy loads.
