A popular choice for drivers, 2025 GMC Sierra 1500 makes things challenging for other full-size pickups by combining strong performance and versatility with cutting-edge technology.
Strong Gas and Diesel Engines
Pairing to an eight-speed automatic transmission, this edition's base engine is the 2.7-liter TURBOMAX, which is both fuel-efficient due to its smaller size and turbocharged, allowing it to deliver 310 horsepower. If you plan to tow trailers or campers, two other engines can both pull up to 13,200 pounds when the truck's fully equipped: a 420-horsepower 6.2-liter V8 and a 305-horsepower 3.0-liter turbo-diesel I-6 that offers up to 29 MPG in fuel economy.
The largest engine, a 420-horsepower 6.2-liter EcoTec3 V8, comes standard in Denali models along with an active dual exhaust, which allows you to switch between Quiet Mode for peaceful drives and Sport Mode for a sportier, more aggressive sound. It also comes with a Performance Air Intake System for enhanced response.
Versatile With a Rugged Design
A capable 4x4 system comes standard with the AT4, AT4X, and Denali Ultimate trims and is available for all others. The included Hill Start Assist feature provides more stability on steep inclines, and you can easily tackle snow-filled roads with the available Snow Plow Prep Package. Adaptive on pavement as well, the Denali Ultimate trim comes with Adaptive Ride Control, which can adjust the vehicle's ride height and damping as needed.
Skid plates, off-road tires, a lifted suspension, all-terrain tires, and off-road assist steps can be found on select trims, and recovery hooks are available if you should get stuck or need to bail another vehicle out of trouble. This edition offers the available GMC MultiPro Tailgate, which has multiple load-stop and gating functions for securing cargo.Â
Interior Amenities and Technology
Comfort meets convenience inside, as power windows with rear express-down, assist handles, an outside temperature display, and single-zone climate control with rear air vents come standard in the base trim. Many upper trims have dual-zone climate control instead, as well as heated and ventilated front seats, a heated steering wheel, and heated rear seats. In many of these trims, you can also opt for a console-mounted safe, rear under-seat storage, an auto-dimming rearview mirror, and a rear window defogger.
The heart of this truck's many advanced tech features is its GMC Infotainment System, which lets you stream audio and video from smartphones using a Bluetooth connection. This system also has Google Built-In services in upper trims, and there's a Wi-Fi hotspot in every model that can be used when opting for an internet data plan. StabiliTrak, cruise control, the HD Rear Vision Camera, and Forward Collision Alert with Automatic Emergency Braking are just some of many included driver-assist highlights.
While the features covered are impressive, there's much more to see from behind the wheel. Reach out to us today at Holloway GMC in Portsmouth, NH.
