2025 GMC Sierra 1500

The Sierra 1500 offers a diverse lineup that balances rugged performance with upscale styling, making it as comfortable pulling trailers down Highway 57 as it is pulling up to downtown Milwaukee. At its foundation, the Pro trim delivers clean, muscular lines with LED lighting, 17-inch aluminum wheels, and a practical suite of bed features, including 12 cargo tie-downs and the signature MultiPro Tailgate. The Elevation trim strikes a more urban tone, featuring 20-inch gloss-black aluminum wheels and a darkened grille for a stealthy, assertive look. Meanwhile, off-road variants such as the AT4 and AT4X bring adventure-ready style with a factory 2-inch lift, Rancho® monotube shocks, and robust skid plate protection. For serious trail enthusiasts, the AT4X AEV Edition goes even further with AEV-stamped steel bumpers, boron steel construction, and enhanced front-end shielding. At the top of the lineup sits the Denali Ultimate—unapologetically luxurious. It features distinctive Vader Chrome finishes, elegant 22-inch machined wheels, and power-retractable assist steps.

The Sierra 1500's engine lineup speaks to every kind of driver—from those tackling worksites in Ozaukee County to those towing up to 13,200 lbs. to the shores of Lake Michigan. Standard power comes from the robust 2.7L TurboMax™ engine, generating 310 hp and a Class-Leading 430 lbs.-ft. of torque. For those seeking a more traditional V8 experience, the 5.3L V8 offers 355 hp, while the available 6.2L EcoTec3 V8 elevates the experience with 420 hp and 460 lbs.-ft. of torque—ideal for confidently navigating steep grades or highway merges. The 3.0L Duramax® Turbo-Diesel completes the range, delivering an impressive 495 lbs.-ft. of torque and remarkable fuel efficiency. Whether you’re hauling a horse trailer through rural Wisconsin or heading north for the weekend, the diesel variant provides unwavering pulling power.

Brawn is only part of the equation; the Sierra 1500 also delivers intelligent, adaptable performance. GMC’s ProGrade® Trailering System, available across much of the lineup, includes up to 14 unique camera views and a trailering app that simplifies hitching, towing, and diagnostics. It’s a valuable companion on job sites or when maneuvering heavy loads on winding county roads. For those who veer off the pavement, the AT4X stands ready with Multimatic® DSSV dampers, locking front and rear differentials, and advanced off-road tuning. Every system works in concert to maintain balance and control, even when the terrain turns challenging.

Inside, the Sierra 1500 sheds any notion of utilitarian compromise. Its cabin is designed more like a high-end lounge than a traditional pickup interior. Best-in-Class front head and legroom establish a spacious foundation, while the choice of materials—open-pore wood, brushed aluminum, and stitched leather—imbue upper trims with undeniable sophistication. Denali and AT4X models offer 16-way power front seats with heat, ventilation, and massage functionality—features rarely found outside luxury sedans. The technology suite is equally polished, anchored by a 13.4-inch center touchscreen and a 12.3-inch digital driver display. Wireless smartphone integration, built-in Google compatibility, and Alexa integration are all standard. An available 15-inch Head-Up Display and Bose® Premium Sound System ensure that your senses are engaged at every turn.

GMC’s approach to safety is as thorough as its approach to engineering. Every Sierra 1500 comes equipped with the GMC Pro Safety suite, which includes Forward Collision Alert, Automatic Emergency Braking, and Lane Keep Assist. As you move up the trim ladder, features like HD Surround Vision, Rear Cross Traffic Braking, and Front and Rear Park Assist bring added assurance to tight parking situations or busy intersections. Super Cruise®—available on higher trims—adds a layer of semi-autonomous sophistication, allowing for hands-free driving on compatible roads throughout Wisconsin and beyond. It’s a forward-looking system that combines precision, safety, and serenity into every mile.
