2025 GMC Sierra 1500

GMC's 2025 Sierra 1500 lineup consists of the Pro, SLE, Elevation, SLT, AT4, AT4X, Denali, and Denali Ultimate trims. Each features the six-function MultiPro tailgate as standard. This clever design switches between a regular tailgate, workspace, cargo extender, or step — perfect for both jobsite tasks and family outings.

The Pro trim offers practicality with clean styling. The SLE and Elevation add nicer wheels and matching exterior elements, while the SLT brings chrome touches and LED lighting for a classier appearance. Off-roaders will love the AT4 and AT4X, which tackle rough terrain with raised suspension, skid plates, and trail armor. Their 2-inch lift improves clearance and gives them a tougher appearance. The Denali and Denali Ultimate crown the lineup with premium chrome details, signature grilles, and advanced lighting.

The Pro, SLE, and Elevation trims pack the 2.7-liter TurboMax I-4 engine. It cranks out 310 horsepower and 430 pound-feet of torque and can pull up to 9,500 pounds. It's zippy in city traffic yet handles weekend adventures with ease. Available from the Pro to Denali trims, the 5.3-liter EcoTec3 V-8 delivers classic truck power with that V-8 sound that drivers love.

The Duramax 3.0-liter Turbo Diesel I-6, available on the SLE through Denali Ultimate, blends muscle with efficiency. Its steady torque tackles heavy loads while saving fuel on long trips. For raw power, the 6.2-liter EcoTec3 V-8 on higher trims delivers confident acceleration, passing on highways or merging with ease.

When properly equipped, the Sierra 1500 can tow up to 13,300 pounds — boats, campers, and trailers are no problem. With 8,920 pounds of max payload capacity, it tackles both workweek loads and weekend toys with equal confidence. Its stout frame and cooling systems keep performance steady even during steep climbs in hot weather. Trailer side blind zone alert covers the length of your trailer, spotting dangers your mirrors can't see.

On compatible highways, Super Cruise™ takes over steering while you supervise, even while towing — something few trucks offer. With fourteen camera angles, including a "see-through trailer" view, tight spots are easier to handle. Smart suspension tuning delivers comfort whether empty or loaded, adapting to road surfaces and cargo weight automatically.

The Sierra's cabin combines comfort and tech for work and play. The SLE and higher trims feature a 13.4-inch touchscreen, while all models include wireless Apple CarPlay and Android Auto for instant connectivity. The 12.3-inch driver information center displays everything from fuel data to trailer info with customizable layouts.

The cab offers best-in-class front headroom and legroom, seating eight passengers comfortably. The Denali Ultimate includes premium leather and real wood trim worthy of luxury vehicles. The 12-speaker Bose system fills the cabin with clear sound, and OnStar® Connected Services helps with emergencies and navigation, adding peace of mind to every trip.

Every Sierra 1500 includes forward collision alert with automatic emergency braking to help avoid front-end crashes. It monitors traffic ahead, warning you of dangers and braking when necessary. Lane-keep assist and lane departure warning nudge you back into your lane if you drift — a lifesaver during long trips.

Higher trims add adaptive cruise control that keeps pace with traffic — great for highway drives. Front and rear park assist spots hidden hazards such as short posts or curbs when parking. Together, these features protect everyone on board.
