Outstanding power, a comfortable cabin, a large infotainment screen, and advanced safety technology are some of the reasons you should drive the 2025 GMC Sierra 1500. This versatile light-duty pickup truck is waiting for you at your local GMC dealership in St. Peters.

It Has a Range of Powerful Engine Options
You can choose the level of performance you need from the pickup truck thanks to its four engine options. The base model is powered by a TurboMax inline-4 that churns out 310 hp and 430 lb-ft of torque. While it isn’t the most powerful option in the lineup, the TurboMax engine provides a sharp throttle response for everyday driving and plenty of muscle for towing and hauling.
Drivers who want more power at their disposal can opt for the available 5.3L gas engine, which produces 355 hp and 383 lb-ft of torque, or the 6.2L V8, which produces 420 hp and 460 lb-ft of torque. The Sierra 1500 also offers an available Duramax 3.0L Turbo-Diesel engine with 305 hp and 495 lb-ft of torque. It is an excellent choice for long-distance driving and supports a towing capacity of 13,200 lbs.
It Offers Outstanding Off-Road Capabilities
You can confidently drive beyond the pavement with the Sierra 1500’s off-road trims. The AT4 model offers underbody skid plates, a 2-inch factory lift, an off-road-tuned suspension with Rancho monotube shocks, and a two-speed Autotrac transfer case. Meanwhile, the more extreme AT4X model offers AEV skid plates, front and rear electronic locking differentials, and Multimatic DSSV dampers.
It Has a Luxurious Cabin
The Sierra 1500’s cabin provides outstanding long-range comfort. On select trims, the pickup truck features perforated leather seating surfaces, 16-way power adjustment for the driver and front passenger, heated and ventilated front seats, and heated rear seats. Standard and available in-cabin amenities include dual-zone automatic climate control, wireless phone charging, and a 12-speaker Bose premium audio system.
