2025 GMC Sierra 1500 interior

GMC trucks are legendary for the rugged styling, hard-working capability, and elevated features that distinguish the brand from its competitors. The 2025 GMC Sierra 1500 opens the next chapter of automotive excellence from GMC’s line of light-duty full-size trucks, providing many impressive details that set it apart from the crowd.  

Versatile Power and Efficiency Thanks to Four Engine Options

Thanks to four versatile engine options, the Sierra 1500 is perfect for any purpose, whether it’s traveling around town or hauling heavy loads to the jobsite. The base engine is the innovative and efficient TurboMax, which generates 310 horsepower and 430 foot-pounds of torque when paired with an 8-speed electronically controlled automatic transmission. Available in either RWD or 4WD, the Sierra can handle any task required with power and efficiency.

For those who prioritize V8 power, there’s a 5.3-liter EcoTec3 V8 that churns out 355 horsepower and 383 foot-pounds of torque, and an even larger 6.2-liter V8 that produces 420 horsepower and 460 foot-pounds of torque. Both V8 powerplants are paired with a 10-speed electronically controlled automatic transmission. There’s even a 3.0-liter Duramax turbo diesel available for diesel aficionados that offers 305 horsepower and 495 foot-pounds of torque.

Impressive Towing and Payload Hauling Capabilities

The towing and payload capabilities of the Sierra 1500 are impressive, whether you’re transporting people and gear in the cab, hauling a bed full of building materials, or towing a boat to the nearest body of water. The Sierra comes with a standard 6.5-foot bed that offers 71.7 cubic feet of cargo volume and a maximum payload capacity of 2,530 pounds when properly outfitted.

The towing capacity of the Sierra 1500 gives it the power to pull heavy loads with ease, with a maximum capacity of up to 13,300 pounds with the proper equipment. A robust lineup of tow-friendly features and accessories streamlines the task of trailering even further, and those features include options like the ProGrade Trailering System, hitch guidance, hitch view, an in-vehicle trailering app, built-in trailer hardware, and auxiliary trailering cameras.  

Incredible Infotainment and Driver Assistance Technology

Modern technology is thoroughly embraced in the Sierra 1500 through its many safety, driver assistance, and infotainment systems. It includes many innovative driver assistance features, which helped it secure a 5-star overall safety rating from the National Highway Traffic Safety Administration. Those features include the Pro Safety system, forward collision alert, lane keeping assist, automatic emergency braking, and following distance indicator.

The infotainment features in the Sierra 1500 include the GMC Premium Infotainment System, built-in Google compatibility, a 7-inch color touchscreen display, a 3.5-inch driver information center, Wi-Fi hotspot capability, and Apple CarPlay and Android Auto connectivity.

The Sierra 1500 embodies everything a driver could want in a full-size truck, with multi-purpose power, rugged good looks, and a range of helpful features that keep occupants safe and connected. Contact Sommer’s Buick GMC of Mequon, WI, today to schedule a test drive.
