What’s New for 2025
The 2025 GMC Sierra 1500 doesn’t undergo a complete redesign this year, but it does receive several noteworthy updates that keep it fresh in a fiercely competitive segment. GMC has focused on refining the truck’s technology offerings and interior comfort, while maintaining the rugged capability that buyers expect.
Among the most significant changes is an upgraded infotainment system with improved processing speed and enhanced voice recognition. The display remains generously sized at 13.4 inches, but now features sharper graphics and more intuitive menus. Wireless Apple CarPlay and Android Auto continue as standard features, but now operate more seamlessly thanks to improved connectivity.
GMC has also expanded the availability of its Super Cruise hands-free driving technology to more trim levels, making this advanced driver assistance system accessible to a broader range of buyers. The system now works even when towing, a significant convenience for those who frequently haul trailers.
Interior materials see subtle improvements across most trim levels, with higher quality touchpoints and more sound deadening material to create a quieter cabin. The MultiPro tailgate, one of GMC’s signature features, now comes standard on more trims and includes additional functionality for 2025.
On the powertrain front, the Sierra’s engines carry over largely unchanged, but GMC has retuned the 10-speed automatic transmission for improved smoothness and responsiveness. The available adaptive suspension system also receives updated calibration to better balance ride comfort and handling.
Exterior Design: Refined Ruggedness
The 2025 Sierra 1500 maintains GMC’s distinctive design language with its bold, squared-off front end and muscular proportions. The massive grille and C-shaped LED signature lighting continue to make a strong first impression, announcing the Sierra’s arrival with authority.
For 2025, GMC has introduced two new exterior colors—Northern Light Blue Metallic and Desert Sand Metallic—while subtle design tweaks include redesigned wheel options across the lineup. The AT4X trim, Sierra’s off-road specialist, gets new skid plates and slightly revised front-end treatment to enhance its already impressive approach angle.
The MultiPro tailgate remains one of the Sierra’s standout features. This six-function tailgate can transform into a work surface, load stop, or even provide easier access to the bed. For 2025, GMC has made it standard on all but the base Pro trim level, recognizing how popular this innovative feature has become with buyers.
Bed options continue with three choices: a short 5-foot-8-inch box, standard 6-foot-6-inch box, or long 8-foot box, depending on cab configuration. The CarbonPro carbon-fiber composite bed remains available on upper trims, offering exceptional durability without adding weight.
LED lighting is now standard across all trims, including bed lighting that makes working in low-light conditions much more manageable. Higher trims continue to offer power-retractable assist steps that automatically deploy when doors open—a thoughtful touch for a truck that sits relatively high off the ground.
Interior Comfort and Technology
Inside, the 2025 Sierra 1500 continues to elevate what buyers expect from a pickup truck. The cabin design balances functionality with premium materials, particularly in higher trims like the Denali and Denali Ultimate.
The dashboard centers around that 13.4-inch touchscreen, complemented by a 12.3-inch digital instrument cluster. For 2025, GMC has improved the system’s responsiveness and added more customization options for the digital display. Voice commands work noticeably better this year, recognizing natural speech patterns with fewer errors.
Upper trims showcase genuine open-pore wood trim, leather surfaces, and contrasting stitching that wouldn’t look out of place in a luxury SUV. Even mid-range models like the SLT offer comfortable accommodations with durable yet attractive materials. Only the base Pro model feels utilitarian, with its vinyl floors and cloth seats clearly designed for work rather than comfort.
The Sierra’s seats have been redesigned for 2025, with improved bolstering and cushioning to reduce fatigue on longer drives. Front seats in SLT and above trims offer heating and ventilation, while rear seats in crew cab models are spacious enough for adults to sit comfortably on extended trips.
Storage solutions abound throughout the cabin. The center console can swallow laptops and tablets, door pockets easily hold large water bottles, and crew cab models feature underseat storage that keeps valuable items hidden from sight. For 2025, GMC has added more USB-C ports throughout the cabin, recognizing the changing needs of tech-savvy buyers.
The available 15-inch head-up display continues as one of the largest in any production vehicle, projecting speed, navigation directions, and driver assistance information directly in the driver’s line of sight. This feature pairs particularly well with the enhanced Super Cruise system, which now covers over 400,000 miles of mapped highways across North America.
According to J.D. Power’s latest reliability study, GMC has shown improvement in infotainment reliability, addressing what had been a pain point in previous models.
Powertrain Options: Power for Every Purpose
The 2025 Sierra 1500 continues to offer a diverse lineup of engines, allowing buyers to prioritize fuel economy, capability, or performance according to their needs.
The base engine remains a 2.7-liter turbocharged four-cylinder, producing 310 horsepower and a robust 430 lb-ft of torque. This might seem small for a full-size truck, but it delivers surprising punch and reasonable efficiency, making it suitable for buyers who don’t regularly tow heavy loads.
Moving up, the 5.3-liter V8 generates 355 horsepower and 383 lb-ft of torque, providing that traditional V8 soundtrack and linear power delivery that many truck buyers still prefer. For 2025, this engine receives minor calibration updates for slightly improved fuel economy.
The range-topping 6.2-liter V8 pumps out 420 horsepower and 460 lb-ft of torque, delivering authoritative acceleration and confident towing ability. Available only on higher trims, this engine transforms the Sierra into a genuinely quick vehicle despite its size and weight.
The 3.0-liter Duramax turbo-diesel inline-six remains the efficiency champion, producing 305 horsepower and 495 lb-ft of torque while delivering the best fuel economy in the lineup. For 2025, GMC has retuned this engine for slightly more refinement at idle, addressing one of the few complaints about this otherwise excellent powerplant.
All engines pair with a 10-speed automatic transmission that has been recalibrated for 2025. Shifts are smoother and more decisive this year, particularly when towing or climbing grades. Rear-wheel drive comes standard on most trims, with four-wheel drive optional or standard depending on the model.
Towing capacity ranges from 9,100 pounds with the four-cylinder engine to a maximum of 13,300 pounds with the diesel when properly equipped. These figures keep the Sierra competitive, though they fall slightly short of the class-leading Ford F-150.
Driving Experience: Comfort Meets Capability
On the road, the 2025 Sierra 1500 balances the competing demands of comfort, handling, and capability remarkably well. The independent front suspension and either leaf-spring or available adaptive air suspension at the rear deliver a ride that’s more composed than you might expect from a full-size truck.
For 2025, GMC has retuned the electric power steering for better feedback, though it remains light enough for easy maneuvering in parking lots. The brake pedal feels firm and inspires confidence, even when towing heavy loads.
Wind and road noise are well controlled at highway speeds, particularly in higher trims with their additional sound insulation. The diesel engine produces some characteristic clatter at idle, but once underway, it settles into a distant hum that’s hardly noticeable.
The standard Sierra handles well for its size, but the AT4X trim transforms the truck’s off-road capability with Multimatic DSSV dampers, increased ground clearance, and underbody protection. New for 2025, the AT4X features updated terrain modes that adjust throttle response, transmission behavior, and stability control intervention based on the selected surface.
Super Cruise continues as GMC’s flagship technology, allowing true hands-free driving on compatible highways. The system has been expanded for 2025 to include automatic lane changes and trailering capability, making long-distance journeys significantly less fatiguing. The implementation feels polished and inspires confidence, with clear indicators showing when the system is active and when driver intervention is required.
Fuel economy varies widely depending on engine choice and drivetrain. The diesel leads the pack with EPA estimates of up to 23 mpg city and 30 mpg highway with rear-wheel drive. The turbocharged four-cylinder isn’t far behind, while the V8 engines trade efficiency for power, delivering around 15-17 mpg combined depending on configuration.
Trim Levels and Pricing
The 2025 Sierra 1500 continues GMC’s practice of offering a wide range of trim levels to serve different buyer needs and budgets:
The base Pro trim (starting around $37,000) serves as the work-focused option, with vinyl flooring, cloth seats, and fewer convenience features. It gains standard LED headlights for 2025 but remains fairly basic.
The SLE (starting around $45,000) adds more creature comforts including the MultiPro tailgate, upgraded infotainment, and cloth bucket seats.
The Elevation (starting around $49,000) brings a more distinctive appearance with monochromatic styling, 20-inch wheels, and additional convenience features.
The SLT (starting around $55,000) steps into premium territory with leather seating, heated front seats, and upgraded interior materials.
The AT4 (starting around $62,000) focuses on off-road capability with a 2-inch lift, skid plates, and off-road tuned suspension.
The AT4X (starting around $77,000) takes off-road performance even further with Multimatic DSSV dampers, front and rear locking differentials, and additional off-road technology.
The Denali (starting around $67,000) emphasizes luxury with premium leather, open-pore wood trim, and nearly every technology feature available.
The Denali Ultimate (starting around $84,000) tops the range with unique styling elements, the highest grade leather trim, standard 6.2L V8 or diesel engine, and every available technology feature.
All prices increase by approximately $2,000-$3,000 when equipped with four-wheel drive (where optional), and choosing the larger 6.2L V8 or diesel engine typically adds $2,500-$3,500 to the price.
Technology and Safety Features
Safety technology continues to improve across the Sierra lineup for 2025. Standard on all trims are automatic emergency braking, lane-keeping assist, and automatic high beams. Higher trims add blind-spot monitoring, rear cross-traffic alert, and a 360-degree camera system that’s particularly useful when parking or hitching a trailer.
The aforementioned Super Cruise system remains one of the most advanced driver assistance features available in any pickup. For 2025, it’s available on more trim levels, starting with the SLT rather than being restricted to Denali models.
GMC’s trailering technology suite continues to impress, with up to 15 camera views available to make hitching and towing safer and easier. The system can store profiles for different trailers and even check that lights are functioning properly before you depart.
The infotainment system supports wireless smartphone integration and over-the-air updates that can add features and fix bugs without a dealer visit. For 2025, remote software updates have been expanded to cover more vehicle systems, including certain powertrain calibrations.
A research study from the Highway Loss Data Institute indicates that the Sierra’s driver assistance systems have contributed to lower insurance claim rates compared to previous generations, suggesting real-world safety benefits from this technology.
Practical Considerations: Cargo, Towing, and Utility
The Sierra’s bed options provide flexibility for different needs. The innovative MultiPro tailgate enhances utility with its multiple configurations, though some owners report it can be temperamental in very cold weather.
Inside the bed, the Sierra offers tie-down points, available 120-volt power outlets, and LED lighting. The optional CarbonPro composite bed resists dents and scratches better than traditional steel, though it commands a significant price premium.
For those who tow regularly, the available Technology Package includes a trailer brake controller, hitch guidance with hitch view, and an integrated trailer brake controller. When equipped with the Max Trailering Package, the Sierra can pull up to 13,300 pounds, though this requires specific configuration choices.
Payload capacity ranges from approximately 1,530 to 2,240 pounds depending on configuration, with the lower figures typically applying to crew cab models with four-wheel drive and larger engines.
Pros and Cons
The 2025 Sierra 1500 offers many strengths that justify its position in the market. Its interior quality in higher trims is genuinely impressive, with materials and design that rival luxury vehicles. The MultiPro tailgate continues to be one of the most useful innovations in the truck market, offering genuine utility advantages. The diverse engine lineup means there’s a powertrain for nearly every need, from efficient daily driving to serious towing capability. The Super Cruise system, where available, provides technology that many competitors still don’t offer.
