A silver 2021 GMC Sierra 1500 is angled left.

The GMC Sierra has been a staple on American roads since its introduction in the early 1960s. As one of GMC’s best-selling trucks, the Sierra built its reputation for offering impressive power and performance without sacrificing fuel economy or luxury. That’s exactly the reputation that continues today with the new 2021 GMC Sierra 1500.

With drivers placing even greater demands on trucks, whether working at construction sites and on ranches to weekend projects around the house, GMC has consistently delivered with the Sierra 1500. For 2021, GMC focused on the rise in trailering and towing in American culture and included a new suite of technology to give drivers more confidence behind the wheel. This innovative technology includes everything from Jack-Knife Alert to Rear Trailer View and so much more.

The updates to the Sierra 1500s trailering suite, in addition to its many comfort and convenience features, make the GMC an even more capable workhorse. Its power and capability give drivers peace of mind whether they’re driving to work or towing a camper or boat for a fun-filled weekend at the lake. The Sierra 1500 can truly do it all!
