Chevrolet GMC of Corsicana - What to Know About the 2026 GMC Sierra 1500
The 2026 GMC Sierra 1500 brings work-ready strength, premium comfort and modern connectivity together in a full-size pickup that feels at home on job sites, ranch roads and weekend getaways. At Chevrolet GMC of Corsicana, we help drivers match the right Sierra to their daily needs — from V8 power and diesel towing confidence to hands-free tech that makes long drives easier. As a local truck resource serving Navarro County, Ennis, and Waxahachie, our team is ready to guide you through trims, packages and must-have options.
What stands out first is choice. Sierra 1500 spans hardworking Pro and SLE models, the bold Elevation and well-appointed SLT, the trail-focused AT4 and AT4X, and the ultra-refined Denali and Denali Ultimate. Across the lineup, you get the solid feel of a boxed steel frame, clever bed solutions and a cabin that puts information and control right where you expect it.
- Powertrains: TurboMax engine with 310 hp and 430 lb-ft of best-in-class standard torque; available 5.3L and 6.2L V8s; available Duramax 3.0L Turbo-Diesel.
- Towing: Up to 13,300 lbs available when properly equipped, plus trailering tech that simplifies hitching and monitoring.
- Tailgate: Available MultiPro six-function tailgate to load, step, stop and work with flexibility.
- Bed: High-strength steel with available CarbonPro composite bed for rugged, dent-resistant utility.
- Off-road: AT4 with factory lift and skid plates; AT4X with DSSV dampers and front and rear e-lockers for advanced traction.
- Confidence: Stabilitrak stability control, Hill Descent Control on select trims and selectable drive modes.
- Driver assist: Available Super Cruise for compatible roads, plus a rich suite of camera and trailer views.
Trim differences are meaningful. Pro, SLE and Elevation cover the essentials with smart tech like a large touchscreen and a digital driver display available, plus bed tie-downs and practical storage. SLT adds upscale touches — think chrome exterior details and available trailering upgrades — while keeping costs approachable. Denali and Denali Ultimate shift into luxury pickup territory with signature grilles, premium materials, quiet-tuned cabins and advanced driver assistance features for effortless miles.
If you plan to tow frequently, consider the Duramax 3.0L Turbo-Diesel for its torque-rich pull and long-range efficiency. Pair it with the Max Trailering Package for hardware like a heavy-duty rear axle, enhanced cooling and revised shock tuning. The integrated Trailer Brake Controller and available ProGrade Trailering System help with trailer profiles, maintenance reminders and on-screen checklists, so you spend less time setting up and more time moving confidently.
Tech-forward is an understatement inside the Sierra. An available 13.4-inch Premium GMC Infotainment System with Google built-in puts maps, voice assistance and apps a tap or phrase away. A 12.3-inch Driver Information Center can be configured to show what matters — navigation, towing data, or off-road metrics — and an available 15-inch Head-Up Display keeps key info in your line of sight. Wireless phone integration, multiple USB ports and available premium audio round out a cabin designed to work as hard as you do.
For off-pavement adventures, AT4 provides a factory 2-inch lift, off-road suspension and underbody protection, making rocky two-tracks and muddy leases easier to tackle. Step up to AT4X for next-level control: Multimatic DSSV dampers soak up hits at speed, while front and rear electronic locking differentials help you keep momentum when surfaces get uneven. Add the AEV Edition for stamped-steel bumpers and extra skid protection to explore deeper with confidence.
Shopping smart starts with your use case. Daily driver with occasional towing — look to SLE or Elevation with TurboMax power. Mixed commute and weekend boating — SLT or Denali with the Duramax diesel is a refined, efficient fit. Frequent trail days — AT4X brings the hardware you will appreciate most. No matter the path, our team can walk you through bed lengths, cab configurations and packages that align with your needs.
When you are ready, explore in-stock inventory, compare trims side by side and schedule a hands-on test drive. We can also evaluate your trade and outline purchasing or leasing options, then help you reserve the exact combination of powertrain, color and features you want. From first look to first tow, we will make your Sierra experience straightforward and enjoyable.
