The 2025 GMC Sierra 1500 is a well-rounded pickup truck with brawny performance and a great array of tech and driver assistance features. Whether you need a vehicle for work or off-road adventures, this year’s lineup has trim levels for everyone.

Pro

Building your perfect work truck is easy with the Sierra 1500 Pro. You can mix and match three cab styles and three bed lengths, all of which come standard with a 310-horsepower TurboMax engine. With a towing capacity of up to 9,500 pounds in the regular cab, rear-wheel drive configuration, this model can handle whatever the jobsite throws its way.

SLE

The SLE trim is a great choice for those who need a work truck with next-gen tech features. A 12.3-inch driver information display and a 13.4-inch infotainment touchscreen with Google apps create a digital dash for easy navigation, connectivity, and entertainment. An auto-locking rear differential enhances handling on rough trails, while heated front seats with 10-way power adjustments and lumbar support on the driver’s side enhance comfort.

Elevation

With the standard High Capacity Suspension Package, the Elevation trim is ready to handle heavy loads. This model also comes with LED fog lamps for improved visibility in adverse weather and on trails that kick up dust.

SLT

If you need a higher towing capacity or more power, check out the SLT trim. This model comes with a 355-horsepower 5.3L V8 engine that allows you to tow up to 11,200 pounds with the available Max Trailering Package. Two front recovery hooks are standard, and you can effortlessly manage cargo after dark thanks to the standard bed LED lighting.

AT4

Aboard the AT4, you can explore the most rugged backcountry roads. A 3.0L Duramax turbo-diesel engine with 305 horsepower and 495 lb-ft of torque is standard, delivering the road-gripping traction power that you need. All-terrain tires, off-road suspension with a factory-installed two-inch lift, and Rancho monotube shocks deliver an unrivaled driving experience.

AT4X

The AT4X is even more rugged with Multimatic DSSV dampers and front and rear electronic locking differentials. You’ll also get first-class comfort with 16-way power, heated, ventilated, and massaging front seats.

Denali

The Denali trim is the perfect truck for drivers seeking more luxury. Unique styling elements pair with practical features, such as wheel-to-wheel assist steps. The interior has 12-way power-adjustable front seats, while the authentic open-pore wood and patterned aluminum trims bring visual appeal.

Denali Ultimate

For enhanced performance, unrivaled luxury, and next-gen tech, opt for the Denali Ultimate. This model gets power from a 6.2L V8 engine and comes with an array of high-end features, such as standard Super Cruise hands-free driving.
