The 2.7L TurboMax four-cylinder is standard on the Pro, SLE, and Elevation trims and makes 310 horsepower and 430 lb-ft of torque through an 8-speed automatic. The 5.3L V8 produces 355 horsepower and 383 lb-ft and pairs with a 10-speed automatic. The 6.2L V8 steps up to 420 horsepower and 460 lb-ft on a 10-speed and runs with four-wheel drive. The 3.0L Duramax Turbo-Diesel inline-six makes 305 horsepower and 495 lb-ft, and it is the engine that anchors the lineup, with a max tow rating up to 13,300 lbs when properly equipped.

Towing tops out at 13,300 lbs with the Duramax diesel, properly equipped. The 6.2L V8 tows up to 13,100 lbs, the 5.3L V8 up to 11,200 lbs, and the 2.7L TurboMax up to 9,400 lbs, so even a mid-range trim handles the boat, horse, and equipment trailers common around Marble Falls and the wider Hill Country. Trailering hardware scales by trim and includes an integrated brake controller, Hitch Guidance with Hitch View, and the in-vehicle trailering app. Full numbers by engine and configuration live on the Sierra 1500 towing capacity page.
From the SLE up, the Sierra runs a 13.4-inch GMC Premium Infotainment System with Google built-in, and wireless Apple CarPlay and Android Auto are standard across the lineup. A 12.3-inch driver display, available wireless charging, and an available Bose audio system round out the cabin tech. The GMC MultiPro Tailgate, available across the lineup, folds into six positions for loading, a step, or a work surface. Seating runs from three to six depending on cab and trim, and the Denali Ultimate adds available 16-way heated and ventilated front seats. The 2.7L TurboMax earns an EPA-estimated 20 mpg combined, and the available Duramax diesel stretches that to as much as 25 mpg combined.
Every Sierra 1500 includes automatic emergency braking, forward collision alert, lane keep assist with lane departure warning, and front pedestrian braking as standard, and the truck carries a 5-star overall safety rating from the NHTSA. Higher trims add lane change alert, rear cross traffic braking, and available HD Surround Vision for tight parking and trailer hookups.
