2027 GMC Sierra 1500 Limited Review, Interior, Specs – The 2027 GMC Sierra 1500 Limited enters the new model year with significant revisions that elevate it beyond just a placeholder between generations.

2027 GMC Sierra 1500 Limited Redesign and Update Plan
Exterior & Interior
The exterior of the 2027 GMC Sierra 1500 Limited is unmistakably bold, commanding attention with every angle. A more sculpted hood gives the front end a stronger profile, while integrated hood air ducts offer a functional touch, improving cooling and aerodynamics. The side profile remains clean yet muscular, with flared fenders and new 20- and 22-inch alloy wheel designs, available in gloss black or machined aluminum. Optional power-retractable running boards have been enhanced to lower more quickly in response to door openings and now feature embedded lighting for easier nighttime access.
Step into the cabin, and the Sierra 1500 Limited sets a new benchmark in premium pickup interiors. Depending on trim, you’ll find options ranging from hard-wearing vinyl and durable cloth to high-end full-grain leather and real wood accents. The dashboard layout has been revised with better button placement and a new 13.4-inch infotainment screen that blends into the center console with a horizontal orientation. Wireless Apple CarPlay and Android Auto come standard, along with Google Built-In, which seamlessly integrates navigation, Assistant, and vehicle settings into the interface.
Seating comfort has been notably improved. Front-row seats are now available with 16-way adjustability, heating, cooling, and a massaging function on the Denali Ultimate trim. Rear passengers enjoy increased legroom and new storage compartments beneath the seat bottoms. GMC also introduces a dual-zone climate control system with rear HVAC vents on more trim levels, addressing one of the previous model’s criticisms. Quietness is another standout—enhanced soundproofing in the headliner and door seals results in a cabin that rivals some luxury SUVs in refinement.
Beneath the surface, the Sierra 1500 Limited gets a reinforced high-strength steel frame with updated rear leaf spring tuning to better absorb payload impacts and improve towing stability. GMC has also introduced new dampening mounts that reduce vibration transmission through the cabin—especially noticeable when towing or hauling over long distances. Even the truck bed has seen improvements, now featuring stronger corner tie-downs rated up to 500 pounds and expanded MultiPro tailgate capabilities with enhanced load-stop features and a built-in kicker audio system available on Denali and AT4 trims.
In terms of tech updates, the 2027 Sierra 1500 Limited now comes equipped with the latest version of GMC’s digital architecture, enabling over-the-air updates, faster connectivity, and a customizable digital driver display. New software integration allows improved trailer profiles and towing diagnostics, making this truck smarter on and off the job. While not a full generational leap, the 2027 refresh provides real-world enhancements that users will appreciate daily.
2027 GMC Sierra 1500 Limited Specs
Engine & Performance
The 2027 GMC Sierra 1500 Limited offers a powertrain lineup designed to satisfy both everyday drivers and heavy haulers. The base engine is a 2.7-liter turbocharged four-cylinder, which has been retuned to produce 325 horsepower and 430 lb-ft of torque—numbers that rival V8s from just a few years ago. Paired with an 8-speed automatic transmission, this engine now benefits from better low-end response and reduced turbo lag, making it surprisingly capable for a base model. It’s ideal for light towing and urban driving, where torque delivery is instant and fuel economy more favorable.
For more demanding needs, the 5.3-liter V8 and 6.2-liter V8 engines remain available. The 5.3-liter delivers 355 horsepower, while the 6.2-liter pushes 420 horsepower and 460 lb-ft of torque, making it the best option for buyers prioritizing towing and payload. These engines come mated to a 10-speed automatic that has been recalibrated for smoother downshifts when under load. All V8 models now include Dynamic Fuel Management, enabling the engine to seamlessly deactivate cylinders under light load for improved efficiency without sacrificing performance.
The Duramax 3.0-liter inline-six turbodiesel returns stronger than ever, with a power bump to 305 horsepower and 495 lb-ft of torque. It’s the go-to engine for long-distance towing, offering up to 13,000 pounds of max towing capacity when properly equipped. GMC also introduces an updated exhaust brake system and a smart trailer control module that works in tandem with a camera suite to monitor sway, jackknifing potential, and trailer light diagnostics. Regardless of engine, the 2027 Sierra 1500 Limited delivers confident, composed performance across every trim and terrain. 2027 GMC Sierra 1500 Limited Review
2027 GMC Sierra 1500 Limited Fuel Economy
GMC has made fuel efficiency a priority across the 2027 Sierra 1500 Limited lineup. The 2.7-liter turbo-four returns an estimated 21 mpg city and 24 mpg highway in 2WD form, while the 3.0-liter Duramax diesel achieves up to 26 mpg highway—an impressive figure for a full-size pickup. Even the 6.2-liter V8, thanks to improved fuel management and a new engine stop/start calibration, delivers a respectable 17 mpg city and 22 mpg highway in mixed driving. Optional off-road packages like AT4X will naturally impact mileage slightly but remain efficient for their segment.
2027 GMC Sierra 1500 Limited Safety Features
The 2027 GMC Sierra 1500 Limited brings a full suite of advanced safety tech across the board, making driver confidence a standard feature rather than an optional add-on. All trims now include Forward Collision Alert with Automatic Emergency Braking, Lane Keep Assist with Lane Departure Warning, and Front Pedestrian Braking. GMC has also enhanced the camera system with a new high-definition 360-degree view, trailer-specific views, and a rear camera mirror that gives drivers an unobstructed view even with cargo blocking the rear window.
New for 2027 is the inclusion of the Super Cruise hands-free driving system on the Denali and Denali Ultimate trims. It works on more than 400,000 miles of compatible roads across North America and includes trailer-towing capability. The system also features automatic lane changes, adaptive cruise with full stop-and-go, and real-time driver monitoring to ensure attention remains on the road. For those who spend hours behind the wheel, Super Cruise transforms long hauls into less fatiguing experiences.
Other notable features include rear cross-traffic braking, blind-spot monitoring with trailer coverage, and Intersection Assist, which detects cross-traffic hazards when turning at intersections. A new post-collision braking system automatically applies the brakes after an initial impact to prevent secondary collisions. Combined with a structurally fortified frame and advanced airbag system, the 2027 Sierra 1500 Limited offers peace of mind for both work and family use, making it one of the safest full-size pickups in its class.
