The GMC Sierra 1500 is a full-size pickup offered in Regular Cab, Double Cab, and Crew Cab configurations, with four engines: a 2.7L TurboMax, a 5.3L V8, a 6.2L V8, and a 3.0L Duramax turbo-diesel. With eight trims, from the work-ready Pro to the luxury-focused Denali Ultimate, the right Sierra depends on what you tow, haul, and drive every day. This guide covers the 2026 specs, the differences between trims, towing and payload numbers, and the questions we hear most from drivers in Saint Cloud, Kissimmee, and Poinciana. If you prefer a more compact truck, compare it with the GMC Canyon, and for heavier work, see the GMC Sierra HD.

Start with how you use the truck. The Pro and SLE cover work and daily driving with the standard 2.7L TurboMax engine, and the Elevation adds a Jet Black interior and available Bose audio. The SLT moves up to a standard 5.3L V8 with 10-way power front seats and perforated leather appointments. The AT4 and AT4X are built for off-road driving, with a factory lift, underbody skid plates, and the Duramax turbo-diesel as the standard engine. The Denali and Denali Ultimate focus on luxury, with authentic wood trim, upgraded leather seating, and available Super Cruise, which is standard on the Denali Ultimate along with the 6.2L V8. The trims table above lists the starting MSRP and standard engine for each. GMC describes every trim on its Sierra 1500 page.
The 2.7L TurboMax makes 310 horsepower and 430 lb-ft of torque and is standard on the Pro, SLE, and Elevation. The 5.3L V8 makes 355 horsepower and 383 lb-ft and is standard on the SLT and Denali. The 6.2L V8 makes 420 horsepower and 460 lb-ft and is standard on the Denali Ultimate. The 3.0L Duramax turbo-diesel makes 305 horsepower and 495 lb-ft and is standard on the AT4 and AT4X. The other engines are available on select trims, so ask our team which combinations are offered on the truck you want. GMC lists each engine on its engines page.
GMC rates the 2026 Sierra 1500 to tow up to 13,300 pounds on a Double Cab 2WD standard bed with the available Duramax 3.0L Turbo-Diesel, the available Max Trailering Package, and 20-inch wheels and tires. With the TurboMax engine, GMC lists towing of up to 9,400 pounds, and fifth-wheel or gooseneck towing of up to 9,900 pounds is available on a Double Cab 2WD with the 5.3L V8 and Max Trailering Package. Ratings for every engine and configuration are in GMC’s 2026 Sierra 1500 trailering charts. GMC recommends a tongue weight of roughly 10 to 15 percent of the loaded trailer’s weight, and that weight counts against payload. The Max Trailering Package, available on the SLE, Elevation, and SLT, adds a 9.76-inch rear axle, enhanced cooling, heavier-duty rear springs, and a 220-amp alternator, and the available ProGrade Trailering System helps streamline hitching and towing.
Maximum available payload depends on the cab and bed: up to 2,020 pounds for a short bed Crew Cab, 1,950 pounds for a standard bed Crew Cab, 2,040 pounds for a standard bed Double Cab, and 2,230 pounds for a Regular Cab with either bed. Your truck’s actual payload depends on the engine, 2WD or 4WD, a lifted suspension, and options, and the label in the driver’s door jamb shows the exact figure for that truck. GMC lists the maximums on its Sierra 1500 page.
Every trim is available as a Crew Cab. The Double Cab is offered on the Pro, SLE, and Elevation, and the Regular Cab only on the Pro. Beds come in short, standard, and long lengths, with cargo bed volume up to 89.1 cubic feet, and seating is available for up to six. A Crew Cab with the standard bed has a 157.0-inch wheelbase and 43.3 inches of rear legroom. The available MultiPro Tailgate is a six-function tailgate designed to make loading and working from the bed easier. See GMC’s Sierra truck sizes page for overall dimensions.
EPA-estimated fuel economy in city, highway, and combined mpg is 18/21/20 for the 2.7L TurboMax in 2WD and 17/20/18 in 4WD. The 5.3L V8 is rated 16/20/17 in 2WD and 15/18/16 in 4WD, the 6.2L V8 is rated 15/19/16 in 4WD, and the 3.0L Duramax turbo-diesel is rated 23/28/25 in 2WD. Ratings vary with tires and equipment, and trucks with mud-terrain tires rate lower. You can compare specific configurations on fueleconomy.gov.
The available 13.4-inch infotainment touchscreen has Google built-in and pairs with a 12.3-inch driver information center. Up to 14 camera views are available, and a 15-inch head-up display is available on select trims. Super Cruise hands-free driver assistance is available on the Denali and standard on the Denali Ultimate with a 3-year OnStar One plan, and it works on a growing network of compatible roads. Driver assistance features do not replace the driver’s responsibility to operate the vehicle safely. GMC details the Denali equipment on its Sierra 1500 Denali page.
Both include a factory-installed lift, a two-speed Autotrac transfer case, underbody skid plates, and the Duramax turbo-diesel as the standard engine. The AT4X adds front and rear electronic locking differentials, Multimatic DSSV dampers, an AEV stamped steel front bumper with winch capability, and standard 33-inch mud-terrain tires. GMC lists ground clearance of 11.0 to 11.1 inches on the AT4 depending on bed and 11.5 inches on the AT4X, with a 34.0-degree approach angle and 24.4-degree departure angle on the AT4X. An AT4X AEV Edition is also available. More detail is on GMC’s AT4 and AT4X page.
The Sierra 1500 is GMC’s full-size light-duty pickup. The GMC Canyon is a midsize truck that tows up to 7,700 pounds and is easier to park and maneuver, while the GMC Sierra HD is built for heavier towing and hauling. If your loads fall between those two, the Sierra 1500 is often the fit, and our team can help you compare them side by side.
GMC’s new vehicle limited warranty includes bumper-to-bumper coverage for 3 years or 36,000 miles, whichever comes first. GMC’s Sierra 1500 page also lists a 5-year, 100,000-mile powertrain limited warranty, and GMC lists typical rust-through protection of 6 years or 100,000 miles. Terms can vary by vehicle, so confirm the coverage that applies to the specific truck on GMC’s warranty page or ask our team.
GMC has announced a next-generation 2027 Sierra 1500 with new 5.7L and 6.6L V8 engines rated at 402 horsepower and 428 lb-ft and 481 horsepower and 501 lb-ft, an enhanced TurboMax rated at 350 horsepower and 455 lb-ft, and the Duramax turbo-diesel carried over.
