The 2021 GMC Sierra HD has arrived at Ken Wagner Buick. This pickup comes with an available 6.6-liter turbo-diesel engine and available 10-speed Allison transmission, giving you enough power for heavy towing in and around Wagner. With a fuel economy of up to 16 mpg in city traffic or as much as 22 mpg on the highway, it’s practical enough for everyday driving, as well.


With its advanced camera views, the Sierra HD is designed with your safety and convenience in mind. GMC offers a class-exclusive heads-up display to ensure you never need to take your eyes off the road, along with a host of other safety and driver-assistance features. The multi-function tailgate makes loading and unloading a breeze, while also serving as a bench or additional workspace.




This pickup emulates a sturdy, rugged appearance while still maintaining a great deal of visual appeal inside and out. You’ll find plenty of storage space scattered throughout the well-designed interior, which is capable of seating up to five passengers with ease. The built-in steps provide easy access to cargo, and further enhance the truck’s visual appeal.


The GMC Sierra has won some impressive awards, including Truck Trend’s Pickup of the Year award in 2018 and J.D. Power’s Best Performance for a Large Pickup award in 2018. It offers several “Best in Class” features, including towing capacity and heavy-duty cargo bed volume. The Insurance Institute for Highway Safety gave the truck a “good” rating in nearly every category.
