The heart of this Sierra is the EcoTec3 5.3L V8 engine paired with a 10-speed automatic transmission and 4WD, delivering the power needed for towing and hauling while returning 16 mpg city and 21 mpg highway. The AT4 package elevates this truck with genuine off-road features including an off-road suspension tuned for uneven terrain, auto-locking rear differential, and hill descent control for confident trail navigation.

Inside, the cabin reflects GMC's commitment to comfort and connectivity. The premium infotainment system with navigation keeps you oriented, while Apple CarPlay and Android Auto integration puts your smartphone's functionality at your fingertips. The Bose audio system delivers quality sound throughout the cabin, enhanced by SiriusXM's extensive programming.

Practicality defines this truck's design. The spray-on bed liner with AT4 logo protects your cargo area, while the integrated trailering system with hitch guidance and in-vehicle trailering app simplifies towing tasks. Multiple power outlets—including 120-volt options in the bed and instrument panel—power your tools and equipment wherever the job takes you.

Comfort features abound for daily driving and long journeys. Heated and ventilated front seats maintain your preferred temperature, while the power sunroof adds natural light and fresh air. The remote vehicle starter means your cab is ready when you are, and wireless charging keeps your devices powered.
