2027 GMC Sierra 1500: What's New, Trims, Specs, and Features
The 2027 GMC Sierra 1500 introduces two all-new sixth-generation V8 engines and over 60 inches of combined digital displays, the most in its class. This is the most significant Sierra redesign in years, with a reimagined interior and four distinct powertrain choices. This page covers every trim, spec, and new feature, with links to current inventory at ASA Auto Plaza.
What's New for 2027
The headline change on the 2027 Sierra 1500 is the addition of two all-new sixth-generation Small Block V8 engines. The 5.7L V8 and the 6.6L V8 join the lineup alongside the enhanced 2.7L TurboMax four-cylinder and the Duramax 3.0L Turbo-Diesel Inline-6, giving buyers four powertrain options. GMC states the 6.6L V8 is the most powerful naturally aspirated V8 in the light-duty truck class.
Inside the cab, GMC has rebuilt the interior from the floor up. A 16.3-inch articulating central touchscreen leads the redesign. It is the largest center display in the class and adds a hidden storage compartment behind it. A 12.2-inch digital driver information center, a 15-inch color head-up display, and an 11.5-inch front passenger touchscreen round out a system that combines for more than 60 inches of total screen real estate, a class-first figure.
The MultiPro Center Console is also new to the Sierra lineup, adding a foldable workstation with integrated storage and premium materials. The AT4X trim receives Multimatic Jounce Control Dampers and standard 35-inch Goodyear Wrangler Territory MT tires, giving it a stronger off-road footing than any previous Sierra AT4X.
The 2027 model is available late 2026. Preproduction models are shown in GMC's materials, and actual production models may vary on some features.
Trim Lineup
The 2027 Sierra 1500 offers six trims. They are listed below in order from base to range-topping.
PRO
PRO is the entry point. It delivers the core Sierra platform with the 2.7L TurboMax engine, 10-speed automatic transmission, and the choice of RWD or 4WD. It is built for buyers who need a capable workhorse without additional luxury content.
Elevation
Elevation adds style-focused exterior upgrades over the PRO. It is a strong pick for Austin, MN buyers who want a truck that works hard without sacrificing street presence.
AT4
AT4 is GMC's off-road-focused trim. It adds off-road suspension tuning, skid plates, and available 4WD hardware designed for drivers who take the truck beyond the pavement on a regular basis.
AT4X
AT4X is GMC's extreme off-road configuration, sitting above the AT4 in capability. Standard equipment includes front and rear e-locking differentials, Multimatic Jounce Control Dampers, a 2-inch suspension lift, 35-inch Goodyear Wrangler Territory MT tires, and real carbon fiber interior trim. An available AEV Edition package pushes capability further for serious off-road use.
Denali
Denali is the comfort and technology flagship for buyers who prioritize cabin refinement. It adds premium interior materials, additional technology content, and the refined aesthetic the Denali nameplate is known for.
Denali Ultimate
Denali Ultimate is the range-topping configuration. It adds open-pore forged birch interior trim, Super Cruise hands-free driver assistance with trailering (standard with a 3-year subscription), and the full suite of available luxury content.
Performance and Powertrain
The 2027 Sierra 1500 is offered with four engines, all paired to a 10-speed automatic transmission.
- 2.7L TurboMax Turbocharged 4-cylinder: The 2.7L TurboMax Turbocharged 4-cylinder is the standard engine across the lower trims. GMC has enhanced this engine for 2027 relative to the outgoing version, improving the output characteristics that made it the default choice for fuel-conscious buyers.
- 5.7L V8 (sixth-generation Small Block): The 5.7L V8 (sixth-generation Small Block) is an all-new addition to the Sierra lineup. It delivers the V8 character and broad torque curve that truck buyers have historically expected from a GMC half-ton.
- 6.6L V8 (sixth-generation Small Block): The 6.6L V8 (sixth-generation Small Block) is also all-new and sits at the top of the gasoline powertrain options. GMC positions it as the most powerful naturally aspirated V8 in the light-duty truck segment. GMC Sierra powertrain claims
- 3.0L Duramax Turbo-Diesel Inline-6: The 3.0L Duramax Turbo-Diesel Inline-6 remains the only available diesel engine in its class, according to GMC. It is suited for buyers who prioritize low-end torque and long-haul fuel efficiency, particularly for trailer-towing duty.
Drivetrain choices span rear-wheel drive and four-wheel drive across the lineup.
Interior, Comfort, and Cargo
GMC rebuilt the Sierra 1500 interior for 2027 with an emphasis on material quality and functional design. The MultiPro Center Console is new to the Sierra lineup and operates as a foldable workstation with purposeful storage. On the Denali Ultimate, interior surfaces include open-pore forged birch wood trim. The AT4X uses real carbon fiber trim throughout the cabin.
Seating materials scale with trim. Upper trims receive perforated leather and contrast stitching. A panoramic sunroof is available across select trims, adding light and airflow to the cabin. Available welcome and farewell headlight and taillight animations add a premium feel to everyday entry and exit.
The MultiPro Tailgate continues as a bed feature, offering a bed step, bed extender, and workbench configurations in one integrated system.
Technology and Infotainment
The 2027 Sierra 1500 carries more screen real estate than any prior Sierra.
The 16.3-inch articulating center touchscreen is class-exclusive in its size and pivoting function, and it conceals a storage compartment behind it when open. The 12.2-inch driver information center is configurable and presents clean instrumentation. A 15-inch color head-up display projects key information onto the windshield, reducing eyes-off-road time.
The 11.5-inch front passenger touchscreen, the largest in class, sits behind a retractable cover that keeps it concealed from the driver's line of sight. A Bose Premium Series 16-speaker audio system is available, including class-exclusive front head restraint-mounted speakers in the headrests, a configuration unique to the Sierra at this level.
An 8.5-inch Rear Camera Mirror is available, expanding rearward visibility when hauling or trailering. Super Cruise hands-free driver assistance with trailering capability is standard on the Denali Ultimate with a 3-year subscription included. OnStar Basics provides remote commands, automatic crash response, and in-vehicle apps.
Safety and Driver Assistance
The 2027 Sierra 1500 carries GMC's full suite of available driver assistance technology. Super Cruise, the hands-free driver assistance system with trailering capability, is available on upper trims and is standard on the Denali Ultimate. The Rear Camera Mirror provides an 8.5-inch live view of the trailer and road behind the truck, which is especially useful for buyers in Austin, MN who tow boats or trailers through tight areas.
The standard GMC warranty provides a 3-year / 36,000-mile bumper-to-bumper coverage period and a 5-year / 60,000-mile powertrain warranty. GMC warranty terms
Who It's For vs. the Prior Year
Buyers who ordered a 2026 Sierra 1500 for V8 power are the primary target for this update. The addition of the all-new 5.7L and 6.6L sixth-generation Small Block engines addresses the segment's most-requested powertrain upgrade directly. The rebuilt interior, with over 60 inches of combined displays and the new MultiPro Center Console, puts the 2027 Sierra cabin in a stronger position against the Ram 1500 and Ford F-150 than any previous Sierra generation.
For off-road buyers, the AT4X's new Multimatic Jounce Control Dampers and standard 35-inch MT tires represent a genuine capability jump over the prior AT4X. For luxury buyers, the Denali Ultimate's open-pore forged birch and standard Super Cruise raise the bar above what the 2026 model delivered.
If you drove a pre-2027 Sierra and wanted more engine options or a more refined cab, this is the model year built for you.
