We showed you the pictures yesterday, and now we've got some video to go along with the Denali XT unveiling. While GMC started the unveiling with the introduction of the 2009 Silverado hybrid, you can tell that GMC is more interested in the Denali XT than that standard truck. The XT is a more exciting vehicle - even if it's just a concept - and you can see GMC North America design head Bryan Nesbitt's excitement in the Denali XT's look as he introduces it. Sure, every time a vehicle is unveiled at an auto show, enthusiasm is the rule; I'm just sayin'. Why listen to me, though, when you can watch the event itself in the video above?
