The 2026 GMC Sierra 1500 can tow a maximum of 13,300 pounds when properly equipped. This metric strictly requires the 3.0L Duramax Turbo-Diesel or 6.2L V8 engine, the Max Trailering Package, and specific 2WD or 4WD cab configurations.

Yes. GMC has introduced Glacier White Tricoat and Coastal Dune, replacing previous gray and white variants.

Models equipped with the 6.2L EcoTec3 V8 feature a recalibrated active exhaust system that delivers an enhanced acoustic profile when the vehicle is shifted into Sport Mode.

The four available powertrains include the 2.7L TurboMax I4, the 5.3L EcoTec3 V8, the 6.2L EcoTec3 V8, and the 3.0L Duramax Turbo-Diesel I6.

The highest available payload rating is 2,260 pounds. To achieve this, the truck must be configured with the 2.7L TurboMax engine. Heavier engines like the V8 and diesel reduce total available payload.

Available on the Denali and Denali Ultimate, Super Cruise utilizes LiDAR map data, real-time GPS, and a driver attention monitoring system to allow hands-free driving and automated lane changes on over 400,000 miles of compatible highways.

Stepping up to the SLE, SLT, AT4, or Denali trims equips the truck with a 13.4-inch diagonal center touchscreen featuring Google built-in compatibility.

Yes. Achieving the 13,300-pound maximum requires the Max Trailering Package, which includes a heavier-duty rear axle, upgraded cooling radiator, revised shock tuning, and a higher capacity alternator.

The standard baseline service interval is every 7,500 miles, which includes an oil change, tire rotation, and comprehensive fluid and brake inspections.

The six-function MultiPro Tailgate is standard on the SLT, AT4, Denali, and Denali Ultimate trims, and is available as an option on lower trims.
