Conquer demanding workdays and weekend adventures with this 2026 GMC Sierra 2500 AT4 4WD, powered by a robust 6.6L V8 engineered for torque and towing confidence. The AT4 trim blends purposeful off-road capability with refined comfort: an advanced four-wheel-drive system, factory skid plates, and an off-road-tuned suspension deliver composed handling over rough terrain, while hill-descent control and selectable drive modes make challenging conditions more manageable.
The exterior presents a bold, confident stance with functional design cues—integrated tow hooks, heavy-duty bumpers, and premium lighting that enhance visibility and presence. Inside, premium materials and supportive seating create a work-ready cabin that doesn’t compromise on comfort. Technology features include a large infotainment touchscreen with smartphone integration, multiple USB ports, and an available premium audio system for connectivity and entertainment on the go. Safety and convenience are elevated with driver-assist systems such as blind-spot monitoring, rear cross-traffic alert, and an available surround-view camera to aid maneuvering and hitching.
Capable of handling substantial payloads and trailering needs, this GMC Sierra 2500 AT4 balances serious capability with everyday usability. It’s an ideal choice for drivers who require heavy-duty performance without sacrificing modern amenities and confidence-inspiring features.
