2007
In 2007 the GMC Yukon and Sierra lines were completely revamped with the Denali included, now with a 6.2L V8 (producing 380 HP / 417 lb/ft) in the Yukon Denali and (producing 380 HP/ 417 lb/ft) in the Sierra Denali), six-speed automatic transmissions, and many new features and options such as power folding second row seats and rear backup camera. Styling was also changed, particularly the controversial grill and headlights, which made the Yukon look much less aggressive than any previous models. The MSRP's of the 2007 models were not increased.
