The 2025 GMC Sierra 1500 continues to prove why it’s one of America’s most respected full-size pickup trucks. With around 33,288 units sold in the first half of 2025, this powerhouse pickup dominates the market thanks to its versatility, premium comfort, and strong towing capacity.
Starting at $38,300 MSRP and climbing up to $84,200 for the top-end Denali Ultimate, the Sierra offers a wide range of trims suitable for every kind of driver — from everyday haulers to luxury-focused executives.
Performance and Power
The 2025 Sierra 1500 offers four robust engine options, including a turbocharged 3.0-liter diesel delivering 305 horsepower and 495 lb-ft of torque. The Sierra can tow up to 13,200 pounds, making it one of the most capable trucks in its class.
Drivers can choose between rear-wheel drive (RWD) or four-wheel drive (4WD), and models like the AT4 and AT4X take off-road adventures to the next level with a 2-inch lift, locking differentials, and off-road dampers.
Whether you’re towing equipment for business or heading off the grid, the Sierra 1500 delivers the perfect mix of muscle and refinement.
Fuel Economy and Efficiency
While full-size trucks often sacrifice fuel economy, the Sierra manages to stay efficient. The diesel version returns an impressive up to 26 mpg combined, making it a standout in the segment.
The gas-powered V8s offer between 15–18 mpg combined, and the turbo four-cylinder variant performs admirably at 16–19 mpg.
Interior and Comfort
Inside, the 2025 GMC Sierra 1500 boasts one of the most spacious and luxurious cabins in its class. The Denali and Denali Ultimate trims come equipped with premium leather upholstery, a 13.4-inch touchscreen, 12.3-inch digital gauge cluster, and an 11-speaker Bose audio system.
The Crew Cab configuration is particularly roomy, offering ample legroom and supportive seats for up to six passengers. GMC’s innovative MultiPro tailgate and available bed-view camera system make loading and hauling easier than ever.
Safety and Technology
Safety remains a top priority in the Sierra 1500. It includes forward collision alert, automatic emergency braking, lane-keep assist, and the optional Super Cruise semi-autonomous driving system available on the Denali Ultimate.
The truck earned a five-star overall rating from the National Highway Traffic Safety Administration (NHTSA), reaffirming GMC’s commitment to driver protection and reliability.
