UNLEASHED: THE GMC SIERRA HD AT4 ALL MOUNTAIN

When it comes to legendary locations for winter sport enthusiasts, Vail, Colorado, offers unforgettable experiences for even the most veteran skier — a fitting backdrop to showcase the new, winter adventure-ready GMC Sierra HD AT4 All Mountain concept.

This bold, athletic-looking concept truck celebrates GMC’s ongoing partnership with Vail Resorts®. All Mountain builds off the Sierra HD AT4’s bold, athletic look and off-road capability with purpose-built features to take on harsh winter weather. This includes one of its most visible and unique components — the tracks. These ruggedly capable tracks come from Mattracks® and provide an increased ability to glide through dirt, mud and snow. 

Multiple accessories have also been equipped to the Sierra HD AT4 All Mountain to emphasize the active lifestyle that the AT4 brand embodies. They include three-inch black off-road assist steps, front-mounted light bar, accessory lights in the wheel liners and underbody, tonneau cover, sport bar with accessory lights and speakers, and MultiProTM Tailgate with MultiPro Audio System by KICKER®†. Topping it off is a custom wrap with imagery inspired by Vail’s renowned reputation for winter sports, complementing Sierra HD AT4’s existing strong appearance. 

For those who don’t make it to Vail, additional Sierra HD AT4 All Mountain concept trucks will also be on display at Park City Mountain Resort in Park City, Utah, and Mt. Brighton Ski Area in Brighton, Michigan.

The partnership between GMC and Vail Resorts® and Vail Valley Foundation includes complimentary shuttle services at some of the premier resort company’s 16 mountains and 15 lodging properties. In addition, GMC is also continuing to serve as a sponsor for the GoPro® Mountain games in Vail via a partnership with the Vail Valley Foundation, as well as a presenting sponsor for 8 signature Vail Resorts® events. These events include Noel Nights at Northstar in North Lake Tahoe, Vail Film Festival, Beaver Creek® Blues, Brews & BBQ Festival and the EpicMix Race Series.
