If you’re searching for a dependable truck that works for tough jobs and off-road trips, then the 2025 GMC Sierra 2500 HD should be top of your test-drive list. It handles heavy work with ease and tackles any terrain you throw it at.
Most of the seven trim levels use a 6.6L V8 gas engine with 401 horsepower, which is matched to a 10-speed Allison automatic transmission for smooth power delivery. That’s nothing to sneeze at, but, of course, you can get even more with an optional 6.6L V8 turbo diesel engine that gives you a massive 470 horsepower.
That engine also comes standard on the top Denali Ultimate. Go for the diesel if you want better efficiency, torque, towing, and grip. The base Pro trim starts with rear-wheel drive, but you can add four-wheel drive on any model.
Built for Tough Jobs
This truck is made to carry and tow big loads. It has a standard gross vehicle weight rating of 10,450 pounds, so you can load up the bed with all the heavy gear you have. With the right setup and the diesel engine, it can tow as much as 20,000 pounds, which means you’ll be ready for handling all kinds of trailers.
On all trims except the Pro, the In-Vehicle Trailering App is either available or standard. This app makes it simple to monitor your trailer’s condition and upkeep.
Options for Every Crew
Choose from different cab setups to fit your group. The Regular Cab comes only with a long bed for max cargo space and seats up to three people. Double Cab and Crew Cab give you standard or long bed choices, with room for up to six passengers.
Modern Features
The infotainment system makes controlling the truck easy. Hands-free calling is standard, and you can connect your phone using Apple CarPlay or Android Auto for apps and music. The Pro trim includes remote keyless entry, and higher trims add keyless entry and start. Select models come with built-in SiriusXM and a free trial.
Standard Safety Tools
The Pro Safety package includes lots of driver aids, like automatic emergency braking. A high-definition rear camera helps when you’re reversing or parking, and there’s even a teen driver mode included to support young drivers in building safe habits.
