For long diesel hauls, the available Duramax® 3.0L Turbo-Diesel is engineered for confident torque and an available max diesel towing capacity of up to 13,300 lbs.

Key Features of the 2026 GMC Sierra 1500
TurboMax™ Engine
The standard TurboMax™ engine pairs 310 horsepower with best-in-class standard 430 lb.-ft. of torque, giving you the low-end pull that matters when you’re merging onto US-12 with a trailer in tow or crawling up a rutted two-track. It’s tuned to deliver confident power without drama, and it’s backed by engineering that emphasizes durability for the long haul. The result is a powertrain that shrugs off daily commuting and weekend hauling with equal ease, while offering available max towing up to 9,400 pounds, when properly equipped. For shoppers who want robust performance without stepping up to a larger-displacement engine, TurboMax™ hits a sweet spot of thrust, efficiency-minded engineering, and long-term dependability.
Duramax® 3.0L Turbo-Diesel
For extended towing or high-mileage road warriors, the available Duramax® 3.0L Turbo-Diesel brings quiet confidence and strong torque delivery. Paired with a 10-speed automatic, this diesel option is designed to keep revs low and power on tap, especially useful on rolling grades with a boat or camper in tow. When properly equipped, the Sierra 1500 with the Duramax® 3.0L Turbo-Diesel offers an available max diesel towing capacity of up to 13,300 lbs., making it a standout for serious weekenders and light commercial use. It also integrates seamlessly with available trailering features like the ProGrade® Trailering System and Trailer Brake Controller to help keep your load stable and under control.
Super Cruise®
Available Super Cruise® hands-free driver assistance technology brings next-level convenience to compatible roads. With precise lane centering, automatic speed control, and an attentive driver monitoring system, Super Cruise® can reduce fatigue on long stretches of divided highway. Select trims, including Denali and Denali Ultimate, make Super Cruise® available so you can enjoy a more relaxed drive between job sites or weekend destinations. Built to work alongside other driver-assist technologies, Super Cruise® serves as an enhancement for well-marked routes while keeping you engaged and in command. For shoppers who log serious highway time, this single feature can redefine how a truck supports daily life.
MultiPro™ Tailgate
The available MultiPro™ Tailgate brings six functional positions that reshape how you load, step up, secure, and work around the bed. Convert it to a full-width step for easy bed access, a load stop to help keep longer cargo in place, or a work surface that doubles as a jobsite desk. Add the available MultiPro Tailgate Audio System by KICKER for campsite sound without running the engine. Pair these tailgate innovations with the high-strength-steel bed and available CarbonPro® composite bed for a durable, scuff-resistant cargo area designed to take real work in stride. For many owners, this tailgate alone becomes a daily advantage that adds efficiency to every task.
13.4" Diagonal Premium GMC Infotainment System
Inside, the available 13.4" diagonal Premium GMC Infotainment System with Google built-in compatibility places navigation, voice assistance, and your favorite apps within easy reach. The large color touchscreen operates with smartphone-like fluidity, while the available 12.3" diagonal Driver Information Center puts critical info directly in view. Available features like a 15" Head-Up Display, in-vehicle Trailering App, wireless phone projection, and an available Bose Premium audio system broaden functionality and comfort. It’s all part of a cabin designed to work as a connected command center, whether you’re managing multiple trailers or winding down after a long day.
5 Buying Considerations Before You Choose Your GMC Sierra 1500
- Cab and bed configuration: Decide among Regular, Double, and Crew Cab, then match the bed length to your cargo needs and parking realities.
- Powertrain priorities: Choose TurboMax™ for all-around punch, Duramax® 3.0L Turbo-Diesel for frequent towing, or an available V8 for classic pickup muscle.
- Trailering hardware: Add the available Max Trailering Package, ProGrade® Trailering System, and an available integrated Trailer Brake Controller if you’ll pull regularly.
- Off-road needs: AT4 or AT4X add a factory lift, off-road suspension, underbody protection, and advanced components for serious backroad use.
- Technology and safety: Consider available Super Cruise®, the 13.4" infotainment system with Google built-in, and driver-assistance features that fit your driving routine.
Use your daily routine as the anchor for these decisions. If your week involves tight downtown parking and occasional runs to Hells Gate State Park, a Crew Cab with the short bed and TurboMax™ engine could be ideal. If your life is built around longer hauls and a heavier trailer, the Duramax® 3.0L Turbo-Diesel with trailering packages is the smart play. Off-road explorers will appreciate AT4 or AT4X hardware on muddy access roads and rocky overlooks.

Step-by-Step Tips for Test Driving the 2026 GMC Sierra 1500
- Confirm seating and ergonomics: Adjust the driver’s seat, steering wheel, and mirrors; explore storage, visibility, and control placement.
- Sample the tech: Pair your phone, explore the 13.4" infotainment system, test voice commands, and review the 12.3" Driver Information Center layouts.
- Evaluate ride and handling: Drive over mixed pavement and a few imperfect surfaces to feel suspension composure and cabin isolation.
- Assess engine response: Perform a couple of rolling accelerations to note TurboMax™ torque response and transmission shifts.
- Practice trailering tools: If available, preview the ProGrade® Trailering System menus and camera views; review hitch guidance.
- Use the bed and tailgate: Operate the MultiPro™ Tailgate positions and inspect tie-down points and bed lighting.
- Check driver-assist settings: Review available settings like Adaptive Cruise Control, lane features, and camera systems for clarity and ease of use.
A thoughtful test drive should mirror your real life—urban errands, a highway merge, a rougher cut-through, and a quick stop to deploy the MultiPro™ Tailgate. If off-road capability matters, consider an AT4 or AT4X demo route that includes a graded dirt road to feel suspension tuning and traction aids at work.
