Vast Engine Options
Whether you’re looking for efficient commuting power or seeking heavy-duty towing, there’s an engine option for you. Standard on lower trims is a 2.7L TurboMax I-4 that produces 310 hp and 430 lb-ft of torque. It’s the most efficient of the bunch, with up to 22 mpg on the highway. An available 5.3L V8 delivers 355 hp, while a 6.2L V8 (standard in top trims) generates up to 420 hp and is 4WD only.
An available 3.0L Duramax Turbo Diesel I-6 produces 305 hp and 495 lb-ft of torque. This torquey engine enables a maximum towing capacity of 13,200 pounds in RWD models.
Drive in Comfort
The Sierra 1500 has multiple trim-specific interiors that range from utilitarian to ultra-luxurious. Most trims can be optioned in Regular Cab, Double Cab, or Crew Cab configurations to meet your space needs. Pro and SLE trims focus on practicality, offering durable cloth seating, manual to 10-way power driver seats, and strategically placed storage bins.
Mid-tier trims such as Elevation and SLT introduce premium cloth or leather-appointed seating, soft-touch materials, and dual-zone automatic climate control. Top-tier Denali and Denali Ultimate trims offer real open-pore wood, aluminum accents, and full-grain leather seating with heated, ventilated, and massaging front seats.
Rugged Looks Meets Versatility
While styling varies across each of the Sierra 1500’s eight trims, all models have a rugged and imposing look that matches the truck’s proficient capabilities. AT4 and AT4X models have off-road hardware such as red recovery hooks, LED fog lamps, skid plates, and standard or optional 33-inch Goodyear Wrangler Territory MT tires.
The Sierra 1500 is offered with three bed lengths, ranging from 5’8″ to 8’0″. The available CarbonPro composite bed is resistant to scratches and corrosion and includes integrated tie-downs. The MultiPro Tailgate, standard on SLT and above, offers six different functions to improve bed access and workability.
Technology Makes Work Easier
Starting with the SLE trim, all models include a 13.4-inch infotainment touchscreen. It features Google Built-In, Alexa Built-In, and wireless Apple CarPlay/Android Auto. The touchscreen is complimented by physical knobs and buttons for ease of use. A 12.3-inch digital gauge cluster is standard on Elevation and above, while a 15-inch Head-Up Display is standard on Denali and Denali Ultimate.
