2025 GMC Sierra 1500 Specs, Features, and Pricing
The 2025 GMC Sierra 1500 excels with strong towing power, versatile powertrains, and endless configurations. It offers a spacious cabin with excellent rear legroom, a large bed with multiple tie-down points, and an easy-to-use touchscreen. The Denali and Denali Ultimate trims add premium materials and advanced features for top-tier luxury.
Engine Options and Performance
The GMC Sierra 2025 has four engines and two transmission options. Rear-wheel drive is standard, and four-wheel drive is available. The Sierra 1500 allows you to customize the towing power, efficiency, and performance based on what tasks you’re looking to do. Depending on the engine, the 2025 Sierra 1500 can easily beat the Ram 1500 in brute power.
The standard setup is a 310 hp 2.7-liter four-cylinder engine, paired with an 8-speed automatic transmission. There are two V8 engines: a 355 hp 5.3-liter and a 420 hp 6.2L V8. The fourth engine is a turbo diesel 3.0-liter six-cylinder engine that produces 305 horsepower and 495 lb-ft of torque. The V8s and diesel engines are paired with a 10-speed automatic transmission.
Ride and Handling
The 2025 GMC Sierra 1500 delivers solid performance on the road and the trail. While its ride can feel firm over uneven surfaces, especially compared to competitors like the Ram 1500, the Sierra remains stable and composed during highway cruising.
For off-road enthusiasts, the AT4 and AT4X trims offer advanced features like locking differentials, skid plates, and specialized dampers.
