Four Engines and Plenty of Pulling Power
The 2.7L TurboMax engine is a smart place to start. It puts out 310 horsepower and 430 lb-ft of torque, which GMC rates as the most standard torque in its class, and teams up with an eight-speed automatic. That's enough muscle to tow up to 9,400 pounds when properly equipped, and GMC backs this engine with a five-year or 100,000-mile Powertrain Limited Warranty. With two-wheel drive, it earns an EPA-estimated 18 mpg city and 21 mpg highway.
If your workload calls for more, the 5.3L V8 comes standard on the SLT and Denali, and the 6.2L V8 powers the Denali Ultimate. Both use a 10-speed automatic. For the heaviest trailers, the Duramax 3.0L Turbo-Diesel is standard on the AT4 and AT4X and can tow up to 13,300 pounds with a Double Cab two-wheel-drive setup, standard bed, Max Trailering Package, and 20-inch wheels. The six-function MultiPro Tailgate also makes loading hay bales or job-site gear easier on your back.
Big Screens, Smart Cameras, and Hands-Free Highway Miles
Starting with the SLE, you get a 13.4-inch touchscreen and a 12.3-inch Driver Information Center, and available upgrades bring the total to over 40 inches of combined driver-focused displays. Google built-in puts voice-driven maps and apps on the dash, while wireless Apple CarPlay and Android Auto bring your phone's music and podcasts onto the big screen.
Long drives across open country get easier with available Super Cruise. It's offered on the Denali and comes standard on the Denali Ultimate with a three-year OnStar One plan, allowing hands-free driving on a growing network of compatible roads. Hitching up gets simpler too, thanks to up to 14 available camera views and the available ProGrade Trailering System, which rolls hitch guidance and trailer monitoring into one setup.
Safety Tech and a Cab Made for Long Days
GMC Pro Safety comes standard on every Sierra, bundling forward collision alert, automatic emergency braking with pedestrian detection, and Lane Keep Assist. Available HD Surround Vision gives you a bird's-eye view around the truck when parking gets tight.
GMC says the Crew Cab has best-in-class standard front headroom and legroom, and the second row gets 43.4 inches of legroom so nobody rides with cramped knees. A heated driver seat, a heated front passenger seat, and a heated steering wheel are standard on the SLE, while the AT4 adds heated and ventilated perforated leather up front. Denali brings authentic wood trim and Forge perforated leather seating, and both the AT4X and Denali Ultimate come with 16-way power front seats with a massage feature.
Comparing Trims on the GMC Sierra near Plainview, TX
The 2026 Sierra lineup has eight trims, so the right fit depends on how you'll use the truck. The Pro handles work duty, the SLE and Elevation add daily conveniences, and the AT4 and AT4X bring factory lifts and off-road hardware for rough ranch roads. Denali and Denali Ultimate sit at the top with the most refined cabins.
