2025 GMC Sierra 1500

The 2025 GMC Sierra 1500 SLT in Volcanic Red Tintcoat offers a premium blend of capability, technology, and refinement. Designed with both everyday usability and serious trailering in mind, this full-size pickup is equipped with the EcoTec3 5.3L V8 engine paired with a 10-speed automatic transmission and four-wheel drive. It balances strong performance with enhanced towing support through the ProGrade Trailering System, which includes integrated trailer brake controller, Hitch Guidance with Hitch View, trailer camera provisions, and an In-Vehicle Trailering System App. The inclusion of the Trailer Side Blind Zone Alert and Rear Cross Traffic Braking provides added reassurance when maneuvering with or without a trailer.

This Sierra SLT features the X31 Off-Road Package, enhancing its all-terrain capability with an off-road suspension, hill descent control, heavy-duty air filter, skid plates, and the X31 Hard Badge. A locking rear differential and front frame-mounted recovery hooks support traction and recovery tasks in challenging conditions. Meanwhile, the dual exhaust system and chrome-accented exterior, including the chrome grille insert bars and wheel-to-wheel assist steps, give the truck a refined yet rugged appearance.

Inside, the crew cab layout offers spacious seating wrapped in Dark Walnut/Slate leather. Front bucket seats are both heated and ventilated, while the second-row outboard seats are heated as well, offering comfort across all climates. The cabin benefits from the SLT Premium Plus Package and the SLT Convenience Package, which combine to add high-end amenities like wireless charging, a premium Bose 7-speaker audio system, navigation, and power-adjustable front seating. Convenience features extend to a power-sliding rear window, dual-zone automatic climate control, and a manual tilt and telescoping steering column with power rake and telescoping capability.

For connectivity and infotainment, the truck includes a 6-speaker audio system with SiriusXM w/360L trial subscription, Wi-Fi hotspot capability, and multiple USB ports across the cabin including data and charge-only Type-C ports. The system integrates smoothly with OnStar services and smartphone-based apps.

Safety and driver assistance features are robust in this configuration. The Sierra Safety Plus Package and additional safety technologies contribute features such as HD Surround Vision, Ultrasonic Front and Rear Park Assist, Rear Pedestrian Detection, Lane Change Alert with Side Blind Zone Alert, and a Safety Alert Seat. These systems collectively enhance situational awareness and help the driver respond to potential hazards. Adaptive Cruise Control and rain-sensing wipers further elevate the driving experience, particularly on longer trips or in inclement weather.

In the bed, practical enhancements include a factory-applied spray-on bedliner with GMC branding, LED cargo area lighting, a 120-volt bed-mounted power outlet, and perimeter lighting for better visibility after dark. Interior cargo support includes rear seat storage and multiple charging ports.
