Available at Mario D'Addario Buick GMC, this full-size pickup is designed to meet the demands of both work and recreation, delivering exceptional towing power, off-road capabilities, and a comfortable, high-tech cabin.

Trim Levels (Exterior)

The 2025 Sierra 1500 comes in several trims, each designed to meet different needs. If you're looking for a straightforward, work-ready truck, the Pro trim has you covered with its no-nonsense functionality. The SLE adds some flair with chrome accents and upgraded tech features.

It’s the perfect mix of sophistication and strength.

Engine (Power)

The 2025 GMC Sierra 1500 offers four engine options to suit different performance needs. The standard engine is the 2.7L TurboMax I-4, producing 310 horsepower and 430 lb-ft of torque, paired with an 8-speed automatic transmission. For more power, the 5.3L EcoTec3 V8 provides 355 horsepower and 383 lb-ft of torque, coupled with a 10-speed automatic transmission. The 6.2L EcoTec3 V8 engine is the most powerful, delivering 420 horsepower and 460 lb-ft of torque, also paired with a 10-speed automatic transmission.

These engine options provide a range of choices to meet various needs, whether you're looking for performance, towing power, or fuel economy.

Performance

The 2025 GMC Sierra 1500 excels in both ride quality and towing performance. Built on a solid body-on-frame construction with independent front and semi-elliptic rear suspension, the Sierra 1500 offers a stable and smooth ride. For those who require maximum towing capacity, the Sierra 1500 can tow up to 13,200 pounds when properly equipped with the 3.0L Duramax turbo-diesel engine and the Max Trailering Package on a 2WD Double Cab model. The AT4 trim, designed for off-road enthusiasts, includes a factory-installed two-inch lift, off-road suspension, Rancho shocks, and an electronic locking rear differential. The AT4X trim takes this even further with front and rear electronic locking differentials, Multimatic DSSV dampers, and optional AEV skid plates and bumpers, making it ideal for the most challenging terrains. For higher trims like Denali, Adaptive Ride Control is available, which electronically adjusts the damping for a smoother, more responsive ride, ensuring comfort and control across a variety of driving conditions.

Interior

The 2025 GMC Sierra 1500 offers a refined and spacious interior, designed with both luxury and practicality in mind. Premium materials, such as leather seating, real wood accents, and brushed metal trim, are used throughout the cabin, especially in higher trims like the Denali. The front seats are power-adjustable and come with heating and ventilation options, ensuring comfort in all seasons. The rear seats offer plenty of legroom, making it ideal for passengers on long drives. The truck’s infotainment system includes a large touchscreen that integrates Apple CarPlay, Android Auto, and Bluetooth connectivity, keeping you connected and entertained. Higher trims also feature a 12-inch digital display and premium audio systems, enhancing the driving experience. Thoughtful storage solutions, including under-seat storage and ample console space, ensure that you can keep your belongings organized while on the go.

Additional available features such as Adaptive Cruise Control, Rear Cross Traffic Alert, and the Surround Vision camera system, which provides a 360-degree view around the truck, enhance the driver’s ability to safely navigate various driving conditions. With its high-strength steel frame and multiple airbags, the Sierra 1500 is built to provide additional protection in the event of a collision, ensuring peace of mind on every journey.
