Exterior & Interior
Inside, the 2027 Sierra 1500 takes a decisive leap forward, offering luxury-level materials even in its mid-tier trims. The dashboard is now dominated by a 16.1-inch curved digital display, integrating both infotainment and the instrument cluster in a seamless glass panel. Google Built-In is standard across the lineup, alongside wireless Apple CarPlay, Android Auto, Amazon Alexa, and over-the-air software updates. A new head-up display projects turn-by-turn navigation, safety alerts, and trailering info directly into the driver’s field of view.
Cabin quality has gone up across the board, with authentic open-pore wood, brushed aluminum accents, and premium leather in Denali trims. Front-row seating includes 16-way power adjustability with massage, heating, and cooling. Rear-seat legroom improves thanks to a flatter floor and revised seat geometry. Under-seat storage bins and modular console space make better use of cabin volume. For those who work on the go, GMC offers a fold-out mobile workstation embedded in the center console, complete with wireless charging and USB-C connectivity.
Functional enhancements include a revamped MultiPro tailgate with improved load sensors and a newly integrated workbench mode. The cargo bed uses upgraded composite material that resists dents and scratches better than ever. Towing-focused trims like the Denali HD and AT4X gain active rear steering, similar to GM’s Super Cruise-enabled SUVs, boosting low-speed maneuverability and trailering precision. A new panoramic roof option and expanded cab configurations allow greater flexibility for buyers looking to tailor the Sierra 1500 to lifestyle, work, or luxury use.

The 2027 Sierra 1500 delivers unmatched versatility with its range of updated engines. The base powertrain is a turbocharged 2.7-liter inline-4 with 340 hp and 420 lb-ft of torque, tuned for improved fuel economy and mid-range torque.

A reworked 3.0-liter Duramax inline-6 diesel offers 305 hp and a robust 495 lb-ft of torque, catering to long-haul efficiency and towing strength.
New for 2027 is a plug-in hybrid variant producing an estimated 450 hp and 500 lb-ft of torque, pairing a V6 gas engine with dual electric motors. It features a 30-mile electric-only range and is targeted at fleet users looking to reduce emissions without sacrificing capability. The Sierra’s 10-speed automatic transmission has been retuned for quicker shifts and smoother low-speed operation. Towing capacity peaks at 13,300 lbs, and payload hits nearly 2,500 lbs in properly equipped models. The AT4X variant brings locking front and rear differentials, Multimatic DSSV dampers, and 35-inch off-road tires for serious trail competence. 2027 GMC Sierra 1500 Review
