The GMC Sierra 1500 has a long and illustrious history that began in 1999. This formidable light-duty pickup truck was originally available in three-bed lengths, cab sizes, and engine options.
Over the years, the Sierra 1500 has undergone several upgrades, from exterior redesigns to updated engine options. Here’s an in-depth look at what this exceptional truck offers in 2025.
Like the previous year’s model, the 2025 GMC Sierra 1500 is available in eight trims. The base Pro trim features a 12V front power outlet and 12 cargo tie-downs, while the next trim in the lineup, the SLE, comes with a heated steering wheel, a heated front-outboard passenger seat, and a 10-way power-adjustable heated driver’s seat.
The Elevation trim comes with most of the features of the SLE but stands out for its monochromatic exterior with gloss-black mesh inserts in the front grille. It also features LED fog lamps and rides on larger 20-inch gloss-black painted aluminum wheels. The next trim is the SLT, which features a chrome grille, door handles, and front and rear bumpers. This trim offers 10-way power outboard seats with power lumbar support.
The next highest trims are the AT4 and AT4X, each offering unique off-road performance features. For instance, the AT4 has a 2-inch factory lift and features off-road suspension and Rancho monotube shocks. The AT4X is the only trim in the lineup with front and rear electronic locking differentials. This enhancement lets you lock the wheels on each axle together so they rotate at the same speed, providing better traction, particularly on wet and muddy roads.
The top-of-the-range Denali and Denali Ultimate trims are remarkable beasts on the Fort Worth roads. The 2025 GMC Sierra 1500 Denali features the signature Denali grille with a chrome header and wheel-to-wheel assist steps. It also offers well-cushioned, perforated leather seating surfaces. The driver and front passenger seats have lumbar support and are power-adjustable 12 ways.
The 2025 GMC Sierra 1500 Denali Ultimate features a 16-way power-adjustable heated and ventilated driver and front passenger seats with a massage feature. It also has a signature Denali Vader Chrome grille and rides on exclusive seven-spoke Ultra-Bright 22-inch machined aluminum wheels with Bright Chrome accents.
The 2025 GMC Sierra 1500 has four robust engine options for your off-road excursions and towing needs. The standard engine is a 2.7-liter TurboMax inline-four that outputs 310 horsepower and 430 lb-ft of torque. When paired with an eight-speed transmission system, this engine delivers a maximum towing capacity of 9,500 pounds.
The 2025 Sierra 1500 also offers a 3.0-liter Duramax turbo-diesel engine capable of producing 305 horsepower and 495 pound-feet of torque. This engine has a built-in electronically controlled variable-geometry turbocharger that provides more responsive acceleration. It features an Active Thermal Management system that helps keep the engine temperature optimal. This engine is matched with a 10-speed automatic transmission system, delivering a maximum towing capacity of 13,200 pounds.
In addition to these engines, the 2025 Sierra 1500 has two V-8 options. The 5.3-liter V-8, standard on the SLT and Denali trims, churns out an impressive 355 horsepower and 383 lb-ft of torque. Combined with the standard 10-speed automatic transmission, it can tow trailers weighing up to 11,200 pounds.
The other V-8 engine offered on the Sierra 1500 is a 6.2-liter, which is exclusively standard on the Denali Ultimate but available on the SLT, AT4, AT4X, and Denali trims. This engine cranks out an incredible 420 horsepower and 460 lb-ft of torque. It pairs with a 10-speed automatic transmission system and boasts a maximum towing capacity of 13,000 pounds. The 6.2-liter V-8 engine also stands out for its Dynamic Fuel Management system, which improves fuel efficiency by switching off the cylinders when not required.
The GMC Sierra 1500 is a truck widely renowned for its technological innovation, and the 2025 model carries this banner forward. Base trims are outfitted with a 7-inch intuitive infotainment display, while higher trims get a 13.4-inch high-resolution touchscreen. The larger display has built-in wireless Android Auto and Apple CarPlay integration and Google software, providing you with seamless access to maps, a voice assistant, and an app store.
The 2025 Sierra 1500 offers other entertainment and connectivity features, such as the 12-speaker Bose premium sound system, so you can immerse yourself in your favorite songs. At the same time, wireless charging pods ensure your phone never runs out of juice while driving around Fort Worth.
Every 2025 Sierra 1500 trim is equipped with GMC’s Pro Safety suite to ensure your safety on the road. Some notable features in this system include front pedestrian braking, automatic emergency braking, lane-keep assist with lane departure warning, and Intellibeam. While front and rear park assist come standard on the AT4, AT4X, Denali, and Denali Ultimate trims, it’s available as an add-on safety feature on all lower trims.
