Four engines, all with a 10-speed automatic: TurboMax (350 HP, 455 lb-ft), the all-new 5.7L V8 (402 HP, 428 lb-ft), the all-new 6.6L V8 (481 HP, 501 lb-ft) and the 3.0L Duramax turbo-diesel (305 HP, 495 lb-ft).

The all-new 6.6L V8 is standard on Denali Ultimate and available on AT4X.

The 5.7L V8 is standard on AT4 and Denali and available on Pro and Elevation. That's from GMC's Build & Price for a Crew Cab short bed; availability can vary by cab and bed. Compare the engines →

Up to 13,500 lbs with the 5.7L V8 on a properly equipped Elevation Double Cab 4WD standard bed with the Max Trailering Package (late availability), and up to 12,100 lbs with the 3.0L Duramax on a properly equipped Elevation Crew Cab short bed 4WD. GMC has not published tow ratings for the TurboMax or the 6.6L V8 yet. Towing varies by engine, cab, bed, drivetrain and equipment.

EPA fuel economy for the 2027 Sierra 1500 has not been published yet. The one figure GMC has shared is for the diesel: a GM-estimated 27 mpg highway for a 2WD Sierra with the 3.0L Duramax, which gives more than 900 miles of highway range with the new available 34-gallon tank. GMC says the new V8s' new throttle body, dual fuel injection and compression ratio improve efficiency, but it has not published their mpg.

Maximum payload is 2,320 lbs (Regular Cab, standard bed, RWD), 2,230 lbs (Regular Cab, long bed, RWD), 2,040 lbs (Double Cab, standard bed, 4WD), 2,020 lbs (Crew Cab, short bed) and 1,950 lbs (Crew Cab, standard bed, 4WD). Payload varies with equipment, engine, drive type and lift.

Three cabs: Regular Cab, Double Cab and Crew Cab. Bed lengths in GMC's Build & Price are 70.15 inches (short bed), 79.68 inches (standard bed) and 98.42 inches (long bed). Crew Cab comes with the short bed (2WD or 4WD) or the standard bed (4WD), Regular Cab with the standard or long bed, and Double Cab with the standard bed. Bed volume is 62.9 cu ft (short) and 71.7 cu ft (standard).

The AT4 (from $70,700) has the 5.7L V8, a 2" factory lift with monotube shocks, 34" all-terrain tires and an auto-locking rear differential. The AT4X (from $82,700) has the 3.0L Duramax (6.6L V8 available), Multimatic DSSV and Jounce Control dampers, front and rear e-locking differentials, 35" mud-terrain tires, the AT4X-only Baja Drive Mode, underbody cameras, 14-way massaging front seats and an 11.5" passenger screen. Both are 4WD only and come with Super Cruise.

The Denali (from $70,900) has the 5.7L V8, Adaptive Ride Control suspension, 12-way heated and ventilated front seats, a 15" Head-Up Display, a panoramic sunroof, 20" wheels and Super Cruise. The Denali Ultimate (from $85,100) has the 6.6L V8 (Duramax available) and adds 14-way massaging front seats, a 16-speaker Bose Premium Series system with head-restraint speakers, an 11.5" passenger display, underbody cameras, 22" wheels and open-pore forged birch wood trim. Denali comes in 2WD or 4WD; Denali Ultimate is 4WD only.

Super Cruise hands-free driver assistance, which works on compatible roads even while trailering, is available on Elevation Crew Cab and standard on AT4, AT4X, Denali and Denali Ultimate with a 3-year OnStar One plan. It is a hands-free driver-assist system, not a self-driving system.

About 212.1 to 242.6 inches long depending on cab and bed (a Crew Cab short bed is about 233.1 inches), 75.2 to 79.6 inches tall depending on trim and drivetrain, and 81.4 inches wide without mirrors (96.9 inches with). It seats up to six.

It depends on timing and what matters to you. The 2026 Sierra 1500 is on our lot today and may qualify for current GM incentives. The 2027 adds the new V8s, more base-engine power, the 16.3" screen and new off-road hardware, but it has not arrived yet. Our team can price both side by side. See the 2026 Sierra 1500 →
