2025 GMC Sierra 2500

The 2025 Sierra 2500 is GMC's heavy-duty pickup, built for serious towing and hauling duty with a choice of work-oriented and luxury trims. It competes head-to-head with the Ford F-250 Super Duty and Ram 2500 in the heavy-duty segment. Despite its size, the Sierra 2500 steers with surprising precision, and the diesel pulls hard when you need it. The ride is firm when unladen, which is the price of its payload capacity, but the cabin stays quiet and composed on the highway. Inside, the Sierra 2500 offers a spacious crew cab with a large infotainment screen, and the Denali trims add premium materials and a luxurious feel. The off-road suspension and unique front fascia set the AT4 apart from the SLT and Denali trims, giving it a more aggressive look and better capability on rough terrain. Under the hood, the 6.6L V8 pairs with an automatic transmission and four-wheel drive, delivering consistent power for heavy loads without the diesel's extra cost.
