GMC Press Release:
GMC Sierra HD Denali
GMC’s Denali brand represents the most premium and powerful models of the Sierra, Yukon, Yukon XL and Envoy lineups, but the Denali badge has never been applied to a heavy-duty truck – until now. Designers and engineers developed the Sierra HD Denali concept todemonstrates how the
Denali ethic translates to GMC’s most capable trucks. They started with a Sierra 2500HD crew cab and infused it with all of the features and accoutrements expected of a Denali, including unique exterior styling and an enhanced interior. The Sierra HD Denali is powered by the powerful 6.6L Duramax diesel V-8 engine and rides on custom 20-inch wheels.
