Description for 2025 GMC Sierra 1500 AT4 Truck

The 2025 GMC Sierra 1500 AT4 is engineered to meet the demands of off-road capability, interior refinement, and advanced towing technology. Built with a 4WD system and powered by a 3.0L inline-six diesel engine paired with a 10-speed automatic transmission, this truck balances power and efficiency while delivering notable torque for trailering and rough terrain. The exterior is finished in Summit White and features black chrome grille insert bars, red recovery hooks, Off-Road High Clearance Steps, and a factory-applied spray-on bedliner with the GMC logo, underscoring the AT4s rugged design cues.

Inside, the cabin showcases a premium combination of Jet Black leather with Kalahari accents. Comfort and convenience are central themes, with heated and ventilated front seats, heated rear outboard seats, a heated steering wheel, and a dual-zone automatic climate control system. The driver benefits from a 15-inch multicolor head-up display and a digital rear camera mirror, both part of the Technology Package, which also includes HD Surround Vision and rear pedestrian detection for enhanced situational awareness.

The Sierra 1500 AT4 includes both the AT4 Preferred Package and AT4 Premium Package, which collectively add convenience and safety upgrades. Key features include a power-sliding rear window with defogger, power-adjustable steering column, universal home remote, perimeter lighting, and premium floor liners with removable carpet inserts. The premium Bose 7-speaker audio system offers a refined in-cabin listening experience, while the built-in Wi-Fi hotspot, SiriusXM with 360L trial, and wireless charging support connectivity and entertainment needs.

Towing technologies are a strong focus on this model. The integrated trailer brake controller, Hitch Guidance with Hitch View, and Trailer Side Blind Zone Alert assist with safer and more precise trailering. The In-Vehicle Trailering App and trailer camera provisions further enhance towing confidence. Off-road capability is also emphasized through the inclusion of hill descent control, a heavy-duty air filter, and an auto-locking rear differential.

Additional amenities include LED cargo area lighting, rain-sensing wipers, remote vehicle start, push-button start, and numerous USB charging and data ports across both rows. Power windows with express up/down functionality and deep-tinted glass contribute to comfort and privacy.
