2020 GMC Sierra 1500 AT4 Crew Cab 4WD

Premium Strength Meets Off-Road Confidence Some trucks are built for pavement. The 2020 GMC Sierra 1500 AT4 4WD is built for drivers who expect more from their pickup. Finished in bold Onyx Black with a distinctive Jet Black interior accented with Kalahari, this Sierra blends serious capability with premium comfort in a way that feels equally at home on rugged trails, job sites, and daily drives. Power comes from the proven 5.3-liter EcoTec3 V8 engine, paired with a responsive 8-speed automatic transmission that delivers smooth, confident acceleration and dependable pulling power. Whether youre towing equipment or heading out for a weekend adventure, the Sierras V8 provides the kind of strength truck owners expect from GMC. Inside, the cabin reflects the AT4s balance of ruggedness and refinement. Supportive leather-appointed seating is paired with both heated front seats and ventilated front seats, keeping drivers comfortable through Michigan summers and Midwest winters alike. The heated steering wheel and driver memory system for seat and mirrors further enhance everyday comfort, ensuring every drive begins exactly the way you like it. Technology in the Sierra is designed to make driving easier and more connected. The intuitive premium GMC infotainment system with navigation keeps routes clear while the rich sound of the Bose premium audio system with subwoofer fills the cabin. Everyday convenience is handled through wireless charging, universal home remote, and remote vehicle start, helping the truck feel as smart as it is capable. Safety and driver awareness are strengthened through the Driver Alert Package II, which includes technologies like forward collision alert and lane keep assist to help monitor the road ahead. Maneuvering the truck in tight areas becomes easier with the combination of front park assist, rear park assist, and the rear vision camera, providing added confidence whether backing into a parking space or navigating crowded areas. Daily drives might carry this Sierra through Coldwater, Marshall, and Jackson along US-12, M-60, and I-94 across Branch County, Calhoun County, and Jackson County. From there the road can stretch south toward Bryan, Wauseon, and Defiance along US-24, State Route 66, and State Route 15 through Williams County, Fulton County, and Defiance County, before continuing west toward Angola, Auburn, and Fort Wayne along I-69, US-6, and State Road 8 across Steuben County, DeKalb County, and Allen County. The result is a truck that combines off-road strength, everyday luxury, and advanced technology into one confident package.
