“With the all-new next-generation Sierra 1500, GMC isn’t simply raising the bar – we’re redefining it.”
Michael MacPhee, global vice president, Buick & GMC
Built for How Central Wisconsin Uses a Truck
Around here, a half-ton has to haul hay in July, get you to the stand on opening weekend, and start every January morning. The 2027 Sierra 1500 was built for exactly that kind of work.
All-New V8 Power
Two all-new sixth-generation Small Block V8s lead the lineup. The available 6.6L V8 makes 481 horsepower and 501 lb-ft of torque. It’s the most powerful naturally aspirated V8 in its class and the most powerful half-ton V8 GMC has ever built.
Tow the Camper, the Boat, or the Equipment Trailer
When properly equipped with the 5.7L V8, the Sierra 1500 tows up to 13,500 lbs. It also comes standard with 16 cargo-bed tie-downs, the most in its class, so you can secure feed, firewood, or gear. Available front and rear underbody cameras help you see what’s under the truck on a two-track or while you line up a trailer.
Diesel Range for Long Wisconsin Miles
The 3.0L Duramax Turbo-Diesel with the available 34-gallon tank can go more than 900 miles on the highway. That covers a lot of trips to Wausau, Stevens Point, and up north.
A Cabin That Works as Hard as You Do
The 16.3-inch center screen is the largest in the segment, and there’s an available 11.5-inch passenger display. You also get up to 19 camera views, which help when you’re hooking up a trailer in the dark, and a new interface built around truck tasks.
Super Cruise, Standard on Four Trims
The AT4, AT4X, Denali, and Denali Ultimate all come standard with Super Cruise hands-free driver assistance.
