2027 GMC Sierra 1500 Limited Specs, Engine, Review – The 2027 GMC Sierra 1500 Limited has undergone a meaningful refresh that positions it firmly in the top tier of full-size pickup trucks. GMC retained the core muscular silhouette but sharpened it with updated bodywork, slimmer LED lighting, and a revised grille architecture that changes depending on trim level. The front fascia now features more aggressive chrome accents and integrated C-shaped lighting elements, giving it a commanding stance whether parked or in motion. Wheel designs are new across the lineup, ranging from 18-inch blacked-out alloys on lower trims to 22-inch polished multi-spokes on Denali models. 2027 GMC Sierra 1500 Limited Specs
2027 GMC Sierra 1500 Limited Redesign and Update Plan
Exterior & Interior
Step into the 2027 GMC Sierra 1500 Limited, and the difference is immediate. The cabin now exudes refinement, with updated material quality and reworked layouts that prioritize driver focus. Premium cloth and available perforated leather upholstery feel robust and upscale. Real aluminum accents and soft-touch surfaces are standard across the board. Ambient lighting now threads throughout the dash and door panels, enhancing nighttime driving comfort. Everything inside the cabin feels tighter, quieter, and more intuitively placed.
At the center of it all is a redesigned 13.4-inch horizontal touchscreen running the updated GMC infotainment system. It’s faster, cleaner, and easier to navigate, with customizable split-screen functionality. Google built-in continues to offer native Maps, Assistant, and Play Store access. Pair this with a 12.3-inch digital gauge cluster and an available 15-inch head-up display, and the Sierra Limited becomes a digital powerhouse. Wireless Apple CarPlay and Android Auto come standard, alongside a wireless charging pad and over-the-air update capability.
Seating comfort takes a big leap forward. The new front seats offer up to 16-way adjustment, heating, ventilation, and massaging functions on the higher trims. Rear legroom remains best-in-class, and the back bench can now fold flat for additional cargo versatility. Smart storage has been redesigned throughout the interior with deeper under-seat compartments, dual glove boxes, and a reconfigured center console offering both a sliding tray and a hidden safe compartment. The Sierra’s cabin is built to work hard, relax well, and travel far.
GMC has upgraded the Sierra’s aerodynamics subtly but effectively. The 2027 model incorporates active grille shutters, a reshaped hood with better airflow control, and new underbody paneling. These enhancements help with fuel efficiency and highway stability while maintaining off-road capabilities. There’s also a redesigned tailgate badging scheme, plus more color options, including Redwood Metallic and Thunderstorm Gray. The MultiPro tailgate remains a key feature, now enhanced with a wider load stop and more durable corner steps.
For the Limited version, GMC is focusing on bridging high-end tech with the durability buyers expect from a light-duty workhorse. Expect updated camera systems, trailer integration tech, and an enhanced heads-up display. The Limited trim offers some of the Denali and AT4X features in a more accessible package, appealing to buyers who want luxury-level hardware without going all-in on top-tier pricing. It’s a smarter play on value while still looking and feeling premium.

Engine & Performance
Under the hood, the 2027 GMC Sierra 1500 Limited continues to offer a range of powertrains tailored to various needs, but with new refinements aimed at performance and efficiency. The base 2.7-liter turbocharged four-cylinder has been further revised, now delivering a robust 330 horsepower and 430 lb-ft of torque—plenty for hauling and towing without jumping up in size. It’s mated to an 8-speed automatic transmission that’s been retuned for smoother shifts and better responsiveness under load.
The beloved 5.3-liter V8 remains an option, now with enhanced fuel management and direct injection tweaks that improve both output and economy. Producing 355 horsepower, it comes paired with a 10-speed automatic for better gear spacing. For serious power, the 6.2-liter V8 delivers 420 horsepower and 460 lb-ft of torque, enhanced with an active exhaust system and available magnetic ride control on high trims. This engine is a perfect match for buyers who prioritize towing, off-road dominance, or just raw American grunt.
New for 2027, GMC introduces a second-generation 3.0-liter Duramax diesel, now refined for smoother idle, lower emissions, and a modest power bump to 310 horsepower with 510 lb-ft of torque. It’s whisper-quiet at highway speeds and unmatched for long-haul towing efficiency. All models benefit from an upgraded four-wheel-drive system with new drive modes—Tour, Tow/Haul, Terrain, Off-Road, and Snow—customizing everything from throttle mapping to suspension and braking behavior. 2027 GMC Sierra 1500 Limited Specs
2027 GMC Sierra 1500 Limited Fuel Economy
Fuel efficiency in the 2027 Sierra 1500 Limited sees notable gains across the board. The updated 2.7-liter turbo-four delivers an estimated 21 MPG city and 26 MPG highway, thanks to revised combustion profiles and start-stop tuning. The 5.3L V8 averages around 18 MPG city and 24 highway, while the 6.2L V8 offers a still-respectable 17 MPG combined given its output. The standout, however, is the updated 3.0-liter Duramax diesel, returning an impressive 24 MPG city and 31 highway—excellent numbers for a full-size truck with such high towing capacity.
2027 GMC Sierra 1500 Limited Safety Features
The 2027 Sierra 1500 Limited doubles down on active safety. Every model now includes the updated GMC Pro Safety Plus suite as standard. This package includes forward collision alert with pedestrian detection, lane-keeping assist, lane departure warning, blind zone steering assist, rear cross-traffic braking, and automatic emergency braking. A new drowsy driver detection system and intersection collision alert system make their debut as well, leveraging improved radar and camera tech.
Adaptive Cruise Control is more intuitive than ever, with stop-and-go functionality and smoother acceleration/deceleration profiles. Lane centering now works more effectively in tandem with navigation, adjusting speed before curves or exits. High-resolution surround vision cameras assist with parking, trailering, and off-road maneuvering. The Transparent Trailer feature, which virtually renders a see-through trailer view when towing, has been upgraded with sharper resolution and better low-light performance.
For the 2027 model, GMC adds enhanced trailer safety features like Trailer Side Blind Zone Alert and Hitch Guidance with Auto-Leveling. Also new is a fully integrated dashcam recording system, which works with built-in vehicle cameras and stores data on a removable solid-state drive. On the structural side, the frame now incorporates high-strength steel in key areas, and the side-impact zones have been reinforced. It’s a full-circle safety update that works quietly behind the scenes but makes all the difference when it counts.
