At Mario D'Addario Buick GMC in Shelton, CT, we’re excited to offer the 2026 GMC Sierra 1500—a versatile and robust truck that combines power, advanced technology, and unmatched performance. Whether you need a reliable work vehicle, an off-road warrior, or a comfortable everyday driver, the Sierra 1500 is built to exceed your expectations.

Trim Levels (Exterior)

The 2026 GMC Sierra 1500 comes in several trims, each with its unique style and functionality. The Pro trim delivers a tough yet refined look designed for practicality. For those who prefer a more polished appearance, the SLE and SLT trims feature stylish body-color door handles, 20-inch high-gloss black wheels, and LED fog lights. The Elevation trim offers a sporty, bold aesthetic with black accents and striking 20-inch wheels. Off-road enthusiasts will appreciate the AT4 trim, which is equipped with all-terrain tires, a factory lift, and specially tuned monotube shocks. The AT4X takes it a step further with features like advanced Multimatic DSSV™ dampers, an American Expedition Vehicles front winch bumper, and an AEV steel skid plate. At the top of the range, the Denali trim offers luxury with polished wheels, chrome accents, and exclusive styling, while the Denali Ultimate enhances that with a signature Vader Chrome grille, custom 22-inch wheels, and a lavish interior.

Engine Options and Power

The 2026 GMC Sierra 1500 offers a range of engines designed for a variety of needs. From the TurboMax™ engine delivering 310 hp and an industry-leading standard torque of 430 lbs.-ft., to the available 6.2L V8 engine, which provides outstanding performance for tough jobs. For those needing extreme towing power, the Duramax® 3.0L Turbo-Diesel engine stands out, offering a remarkable maximum diesel towing capacity of up to 13,300 lbs.—perfect for hauling heavy loads or towing a trailer on your weekend adventures.

With its powerful engine options, this truck can tow up to 13,300 lbs. when properly equipped, making it one of the top contenders in its class for towing capabilities. The ProGrade™ Trailering System simplifies towing with integrated tools for hitching and maneuvering. Equipped with up to 14 camera views, the Sierra 1500 offers unmatched visibility to help you navigate tight spaces with ease. Available 4WD, off-road suspension systems, and electronic differentials on off-road trims provide superior traction, ensuring stability and confidence, whether you’re navigating rain, snow, or rugged trails. Add exclusive Salta wheels and AEV off-road rocker panels for an added touch of flair.

Featuring high-end materials such as authentic wood trim and perforated leather seating, this truck ensures every journey is comfortable. The Crew Cab configuration provides Best-in-Class front headroom and legroom, making it a great choice for both work and play. The Denali and Denali Ultimate trims take luxury to the next level, with 16-way power-adjustable heated and ventilated seats with massage functions, premium leather upholstery, and a 12-speaker Bose® Premium sound system. With up to 40 inches of digital display space, including a 13.4-inch touchscreen, you’ll have seamless access to wireless smartphone integration, Google Built-In, navigation, and more.
