The 2026 GMC Sierra 1500

The 2026 GMC Sierra 1500 is one of the most capable full-size pickups in its class. It starts at $38,300 MSRP and tows up to 13,300 lbs with the available Duramax diesel. The Sierra 1500 handles a horse trailer to Oaklawn, a boat to Lake Catherine, or a work crew across Hot Springs with the powertrain choice and technology to back it up.

At Allen Tillery Buick GMC in Hot Springs, we carry the full 2026 Sierra 1500 lineup, from the work-ready Pro to the off-road AT4X and the flagship Denali Ultimate. This guide covers the engines, trims, drivetrain options, technology, and capability that define the new Sierra, with a focus on what matters for Arkansas drivers.

2026 Sierra 1500 Engine Options

The 2026 Sierra 1500 offers four engine choices across its trim lineup. The Pro trim is the only one limited to gas options. Every other trim lets buyers choose between gas and diesel based on how they'll use the truck — neither is more "standard" than the other in practice.

2.7L TurboMax I4

Offered on Pro, SLE, and Elevation. Produces 310 horsepower and 430 lb-ft of torque, which GMC notes is class-leading standard torque. Pairs with an 8-speed automatic transmission. EPA-estimated fuel economy is 18 MPG city / 21 MPG highway in 2WD configurations, dropping to roughly 17/20 with 4WD. Available max towing reaches 9,400 lbs properly equipped.

5.3L EcoTec3 V8

Offered on Pro, SLE, Elevation, SLT, and Denali. Produces 355 horsepower and 383 lb-ft of torque through a 10-speed automatic. The V8 character without stepping up to the 6.2L.

6.2L EcoTec3 V8

Offered on SLT, AT4, AT4X, Denali, and Denali Ultimate. Produces 420 horsepower and 460 lb-ft of torque through the 10-speed automatic. The performance engine of the gasoline lineup.

3.0L Duramax Turbo-Diesel I6

Offered on SLE, Elevation, SLT, AT4, AT4X, Denali, and Denali Ultimate. Produces 305 horsepower and 495 lb-ft of torque through the 10-speed automatic. Unlocks the Sierra 1500's maximum 13,300-lb towing capacity when properly equipped with a Double Cab 2WD standard bed, Max Trailering Package, and 20" wheels. Also the most fuel-efficient engine in the lineup at EPA-estimated 23 MPG city / 28 MPG highway in 2WD configurations. The Pro is the only Sierra 1500 trim where the Duramax is not offered.

Drivetrain and Four-Wheel Drive Availability

Six of the eight Sierra 1500 trims offer both rear-wheel drive (2WD) and four-wheel drive (4WD) configurations. The off-road and flagship trims come exclusively in 4WD.

• 2WD standard, 4WD available: Pro, SLE, Elevation, SLT, Denali
• 4WD-only configuration (no 2WD option offered): AT4, AT4X, Denali Ultimate

4WD adds approximately $3,000-$4,500 to the configuration depending on trim. For most Arkansas drivers, 2WD is sufficient for daily driving and light towing. Choose 4WD if you regularly tow heavy loads, drive into the Ouachita National Forest, or face winter conditions in the hill country.

Technology and Connectivity

The 2026 Sierra 1500 brings serious technology, especially from the SLE up. Over 40" of combined driver-focused digital displays (which GMC calls class-leading) anchor the cabin on higher trims, with a 13.4" multicolor touchscreen and 12.3" Driver Information Center standard from the SLE up.

Available Super Cruise hands-free driver assistance technology is the headliner. It lets you take your hands off the wheel on a growing network of compatible roads, including stretches of I-30 between Hot Springs and Little Rock and the broader interstate system across Arkansas. Standard on the Denali Ultimate (with a 3-year OnStar One plan). Available on the Denali as a $2,200 upgrade. Not offered on Pro, SLE, Elevation, SLT, AT4, or AT4X.

The available ProGrade Trailering System on SLT and higher includes trailer light tests, trailer electrical diagnostics, an integrated trailering app, and up to 14 available camera views — useful for backing a fifth-wheel into a tight spot or maneuvering a boat trailer at Lake Catherine on a busy summer weekend.

The six-function MultiPro Tailgate (primary gate, primary gate load stop, easy access step, inner gate, inner gate load stop, inner work surface) is standard on SLT, AT4, AT4X, Denali, and Denali Ultimate. Optional on Pro, SLE, and Elevation when equipped with Regular Cab or Crew Cab. Not available on Double Cab for 2026 (a change from prior model years).

Premium materials, available leather, heated and ventilated seats, and massage functions on AT4X and Denali Ultimate make this a truck you can live in for long highway drives across Arkansas without fatigue.

The available Max Trailering Package on SLE, Elevation, and SLT includes a 9.76-inch rear axle, enhanced cooling radiator, revised shock tuning, heavy-duty rear springs, and 220-amp alternator.

Off-Road Capability

For Arkansas drivers who actually use their trucks off-pavement (hunting the Ouachita National Forest, heading into the Caddo backcountry, or running farm and ranch property near Malvern and Hope), the AT4 and AT4X trims are purpose-built and come in 4WD-only configurations.

Both feature factory 2" suspension lifts, off-road tires, underbody skid plates, and AT4-tuned suspension. The AT4 uses Rancho monotube shocks. The AT4X steps up to Multimatic DSSV dampers and adds front and rear electronic locking differentials for true rock-crawling capability. The AT4X also runs 33" Goodyear Wrangler Territory mud-terrain tires versus the AT4's all-terrain setup.

Terrain Mode is selectable on 4WD models with single-speed transfer cases and is built for very rough roads, grassy fields, low-traction situations, and slow off-road driving. Hill Descent Control is also available, providing controlled descent on steep grades, useful in the hill country south and west of Hot Springs.

Safety and Driver Assistance

GMC Pro Safety comes standard on every 2026 Sierra 1500, including collision-avoidance and driver assistance technologies. Available HD Surround Vision provides a bird's-eye view around the vehicle, and available Front and Rear Park Assist helps with tight maneuvering.

The available Technology Package ($1,525 on AT4, $1,275 on Denali) adds additional driver-assist systems. Super Cruise hands-free driver assistance is available on Denali and standard on Denali Ultimate as detailed above.
