The 2024 GMC Sierra 2500HD AT4 makes a bold first impression with an athletic, trail-ready silhouette that perfectly blends rugged capability and premium style. Its aggressive AT4 styling cues, elevated ride height, and bold LED lighting give it a presence built for exploration and heavy-duty performance alike. Riding on durable off-road wheels with confidence-boosting stance, this Sierra projects capability from every angle.
Power comes from a 6.6 L Duramax turbo-diesel V8 engine paired with a 10-speed automatic transmission and full-time four-wheel-drive capability. The result is immense torque, steady low-end power, and confident control that feels composed on highways, gravel roads, and steep terrain alike — turning heavy towing and tough duty into everyday confidence.
