Why it stands out

The 2026 GMC Sierra 1500 stands out as the more upscale of GMC’s full-size pickup truck siblings, with styling and powertrains that largely overlap with the Chevrolet Silverado 1500 but are presented with GMC’s near-luxury cabin character. Its appeal is rooted in that blend of capability and polish: the Sierra is described as having upscale design, great trailering capability, good connectivity features, and distinct trim levels with special features aimed at a wide range of buyers.

For this generation, the Sierra 1500 offers a broad spread of powertrains, including a 2.7-litre turbocharged four-cylinder with 310 horsepower and 430 lb-ft of torque, a 4.3-litre V6 with 285 horsepower and 305 lb-ft, a 5.3-litre V8 with 355 horsepower and 383 lb-ft, a 6.2-litre V8 with 420 horsepower and 460 lb-ft, and a 3.0-litre inline-six Duramax turbodiesel with 305 horsepower and 495 lb-ft. Transmission choices include six-, eight-, and 10-speed automatics, and rear- and four-wheel drive are available. The trim range is also broad, stretching from Pro and SLE to Elevation, SLT, Denali, Denali Ultimate, AT4, and AT4X, with the Denali models leaning into luxury, the Elevation and AT4 bringing rugged styling, and the AT4X adding heavy-duty off-road hardware, skid plates, beefed-up dampers, all-terrain tyres, and 16-way power heated and ventilated front seats with a massage feature.

A refresh for the 2022 model year brought updated styling, better infotainment functionality, and availability of the General Motors Super Cruise semi-automated hands-free driving system. The MultiPro tailgate also adds a practical twist, with a smaller hinged gate that pops up from the main tailgate to create different configurations. On the downside, the Sierra can be expensive even used, and its engine and trim lineups can be overwhelming, but buyers looking for a full-size truck with strong capability, upscale presentation, and a wide range of configurations will find plenty to like.
