2027 GMC Sierra 1500

The 2027 GMC Sierra 1500 is offered in six trims: Pro, Elevation, AT4, AT4X, Denali and Denali Ultimate. Every model wears a more upright front end with machine-precise forms, a vertical grille and GMC’s evolved seven-shaped headlamps and taillamps. Available welcome and farewell lighting animations add a ceremonial element, while available illuminated GMC signature lighting and quad exhaust outlets give upper trims a more conspicuous road presence. The Pro establishes the range with a utilitarian exterior intended for commercial assignments, fleet use and everyday work. Chrome grille elements, black molded mirror caps, black recovery hooks and 17-inch silver steel wheels produce a purposeful appearance without superfluous ornamentation. Available cab and bed configurations allow Pro buyers to tailor the truck to specific work requirements. The Elevation advances into a darker, more contemporary idiom. High-gloss black grille components, black mirror caps and black recovery hooks are complemented by 20-inch machined-aluminum wheels with Dark Android accents. Available quad exhaust outlets reinforce its athletic personality. The enhanced MultiPro Tailgate is standard, providing six functional positions, four newly integrated tie-downs and an embedded ruler system. The AT4 is configured for drivers who want substantial off-road equipment without abandoning premium comfort. It features a two-inch factory-installed lift, monotube shocks, 34-inch all-terrain tires and an automatic locking rear differential. Its high-gloss black grille, red recovery hooks and available 20-inch machined-aluminum wheels immediately distinguish it from road-oriented Sierra models. The AT4X is the most off-road-capable model in the range. Its specialized hood, illuminated GMC emblem, Shadow grille inserts and horizontal red recovery hooks impart a more bellicose countenance. Thirty-five-inch mud-terrain tires, a two-inch factory lift and first-in-class available front and rear underbody cameras further communicate its intent. The available AT4X AEV Edition adds stamped-steel skid plates, AEV front and rear bumpers, black sport steps, recovery hooks and 18-inch beadlock-capable wheels. Luxury takes precedence with Denali. Signature chrome grille details and multidimensional 20-inch polished-aluminum wheels create a stately exterior without diminishing the truck’s inherent strength. Denali Ultimate goes further with Shadow grille components, an illuminated front GMC emblem, MultiPro Power Steps and 22-inch six-spoke diamond-cut aluminum wheels with Dark Android accents. It is opulent but not diffident. The redesigned cargo bed is equally considered. Elevation, AT4, AT4X, Denali and Denali Ultimate include the enhanced MultiPro Tailgate and a class-leading total of 16 tie-down locations. Four tie-downs are built into the tailgate itself, with each rated at 250 pounds. Depending on configuration, bed capacity ranges from 62.9 cubic feet with the short bed to 89.1 cubic feet with the Regular Cab long bed.

The 2027 GMC Sierra 1500 offers four engines, and each is paired with a 10-speed automatic transmission. The standard TurboMax engine has been thoroughly enhanced, producing 350 horsepower and a best-in-class standard 455 pound-feet of torque. Compared with its predecessor, output increases by 40 horsepower and 25 pound-feet. A redesigned turbocharger, upgraded fuel injection, revised pistons and improved thermal management contribute to that broader performance envelope. The available 5.7-liter sixth-generation Small Block V8 generates 402 horsepower and 428 pound-feet of torque. New dual-fuel injection combines direct and port injection, while a larger throttle body, revised compression ratio and tuned intake manifold help the engine deliver both immediacy and sustained strength. When the Sierra is properly equipped, this engine enables a maximum available trailering capacity of 13,500 pounds. For drivers seeking the most powerful gasoline engine in the lineup, the new 6.6-liter sixth-generation Small Block V8 produces 481 horsepower and 501 pound-feet of torque. GMC identifies it as the most powerful naturally aspirated V8 in its class and the most powerful half-ton V8 the brand has offered. It is standard on Denali Ultimate and available on AT4X and Denali. The available Duramax 3.0-liter Turbo-Diesel supplies 305 horsepower and 495 pound-feet of torque. Its torque-rich character is well suited to towing, highway travel and drivers who want diesel efficiency without moving into a heavy-duty truck. When paired with the available approximate 34-gallon fuel tank, the Duramax can provide more than 900 miles of GM-estimated highway driving range on a full tank. Official EPA estimates may differ. Engine availability varies by trim. Pro and Elevation receive the enhanced TurboMax as standard equipment and offer additional powertrains. AT4 and Denali use the 5.7-liter V8 as their standard engine, while AT4X receives the Duramax diesel as standard. Denali Ultimate begins with the 6.6-liter V8 and offers the Duramax as an alternative. At Stadium Buick GMC, we can help shoppers distinguish between maximum horsepower, diesel torque, towing requirements and anticipated annual driving before choosing a powertrain.

The 2027 Sierra 1500 can tow up to 13,500 pounds when properly configured with the 5.7-liter V8. Maximum capacity requires specific cab, drivetrain, wheel, tire and trailering equipment, and the weight of passengers, cargo and accessories can reduce the amount a particular truck can tow. Payload capacity reaches as high as 2,320 pounds in the appropriate Regular Cab configuration. Available drive modes allow the Sierra to adapt its responses to different roads, loads and terrain. Depending on configuration, selections can include Normal, Sport, Off-Road, Tow/Haul, Terrain and the new customizable My Mode. The AT4X substitutes its exclusive Baja mode for Sport. Baja mode calibrates throttle response, gear selection, damping, traction control and stability management for assertive off-road driving over hard-packed sand, dirt, gravel and other loose surfaces. AT4 strikes a useful equilibrium between everyday drivability and trail capability. Its two-inch lift, monotube shocks, 34-inch all-terrain tires and automatic locking rear differential support travel across imperfect job sites, muddy access roads and unpaved recreational areas. Super Cruise with trailering capability is standard, adding hands-free driving assistance on compatible roads when operating conditions and system requirements are met. AT4X is more specialized. A two-inch factory lift works with Multimatic DSSV dampers and new Multimatic Jounce Control Dampers to manage severe impacts while maintaining body control. Front and rear electronic locking differentials give drivers the ability to secure traction at both axles—a combination GMC states is not offered by another competitor in the class. Thirty-five-inch mud-terrain tires further improve clearance and grip over pronounced obstacles. Available front- and rear-facing underbody cameras act as virtual spotters by supplying real-time views beneath the truck. Integrated washers help clear mud and debris from the lenses. Across the broader lineup, up to 19 available camera views can assist with parking, hitch alignment, trailering and off-road placement. The Sierra’s trailering technology is equally consequential. Available views can include Hitch View, Transparent Trailer View, Rear Camera Mirror and underbody perspectives. The In-Vehicle Trailering App supports trailer profiles and trailer-focused tasks, while the industry-first available Trailer Brake Gain Assistant can help simplify brake-gain adjustment. These technologies do not increase the physical rating of the truck; they help the driver use available capability with greater information and precision.

Every 2027 Sierra 1500 receives a redesigned cabin anchored by a 16.3-inch diagonal center infotainment display and a 12.2-inch Driver Information Center. The new GMC interface integrates compatible Apple CarPlay and Android Auto functions with native vehicle controls. Google built-in can provide access to Google Maps, Google Play applications and Google Gemini, allowing supported vehicle, media and navigation functions to be managed through voice or touchscreen input. The Driver Information Center offers multiple layouts, including Clean, Minimalist, Central Gauge and Tow/Haul configurations. Equipped models add a Dynamic display associated with Super Cruise. An available articulating center touchscreen conceals a storage compartment, while an available 11.5-inch passenger display uses polarized technology intended to keep entertainment content visible to the passenger rather than the driver. More than 60 inches of combined digital display area are available in the upper reaches of the lineup. news.gmc.com Pro retains an industrious arrangement with standard vinyl seating, available cloth upholstery and a 40/20/40 front bench. Covered armrest storage and under-seat compartments preserve useful space for paperwork, tools and personal items. Elevation introduces bucket seats, a 10-way power-adjustable driver’s seat, heated front seats, a heated steering wheel, dynamic ambient lighting and the Sierra-first MultiPro Center Console. Its workstation and integrated storage can make the cabin more functional between appointments or at a job site. AT4 adopts a Forest Storm interior with heated and ventilated 12-way power front seats, heated rear outboard seats, a heated flat-bottom steering wheel and dynamic ambient lighting. Its panoramic sunroof is standard. AT4X uses a richer Timber Mahogany treatment with carbon-fiber accents, enhanced seat bolstering and 14-way heated, ventilated and massaging front seats. A 16-speaker Bose Premium Series system incorporates class-exclusive front head-restraint speakers. Denali offers three interior colorways, detailed stitching, Birch Wood accents and 12-way heated and ventilated front seats with lumbar support. Denali Premium Suspension with Adaptive Ride Control complements the cabin by refining the truck’s on-road comportment. Denali Ultimate is the most elaborate expression. Its Stealth Black interior uses engineered open-pore forged birch wood, contrasting piping and Ultimate-specific details. Fourteen-way heated, ventilated and massaging front seats accompany heated rear outboard seats, a heated steering wheel, a 16-speaker Bose system and the 11.5-inch passenger screen. A 15-inch Head-Up Display, Rear Camera Mirror, articulating center display and standard panoramic sunroof complete a cabin that feels purpose-built rather than merely decorated. GMC Cab selection remains important. Crew Cab models can seat up to six and offer best-in-class standard front headroom and legroom. Double Cab models provide seating for up to five, while Regular Cab trucks seat up to three. Configuration availability will expand as production progresses.

The 2027 GMC Sierra 1500 introduces a broader standard safety foundation across the lineup. Standard technologies include Adaptive Cruise Control, Forward Collision Alert, Enhanced Automatic Emergency Braking, Intersection Automatic Emergency Braking, Front Pedestrian and Bicyclist Braking, Side Bicyclist Alert and Blind Zone Steering Assist. Additional standard systems include Rear Cross Traffic Braking, Reverse Automatic Braking, Rear Pedestrian Alert, Front and Rear Park Assist, IntelliBeam automatic high beams, a Safety Alert Seat and an HD Rear Vision Camera. These features can provide alerts, braking assistance or steering support under certain conditions, but they do not absolve the driver of responsibility for controlling the truck and monitoring the surrounding environment. Adaptive Cruise Control can maintain a driver-selected following gap from a detected vehicle ahead. Front and Rear Park Assist supplies proximity warnings when maneuvering in confined areas. Rear Cross Traffic Braking can alert the driver and apply emergency braking when it detects a vehicle crossing behind the Sierra while the truck is reversing. Side Bicyclist Alert monitors for an approaching cyclist near a side blind zone and can continue providing alerts briefly after the truck has been parked. Front Pedestrian and Bicyclist Braking can warn the driver and provide braking assistance when it detects a pedestrian or cyclist directly ahead within its operating range. Super Cruise hands-free driver-assistance technology with trailering capability is standard on AT4, AT4X, Denali and Denali Ultimate and available on Elevation. On compatible roads, the system can manage steering, acceleration and braking while the driver remains attentive. Automatic Lane Change and Turn Signal Initiated Lane Change are supported on equipped models when the truck is not trailering.
