The GMC Envoy is an SUV from the GMC marque of General Motors. In 2005, a Denali luxury version of the Envoy became available. Both the standard-length wheelbase Envoy as well as the Envoy XL were available with the Denali trim option. The Envoy Denali features the hallmark bullet pattern grille and an upgraded interior with high-end car-like features such as heated power seats, extensive woodgrain trim, and rain-sensing windshield wipers. It also featured the GM Vortec 5.3 liter V8 engine with Displacement on Demand, shutting off four of the eight cylinders when workload was minimal.  Across the range, seating was restyled in hopes to increase comfort and quality of control of driving position. Additionally, a touch DVD navigation system was offered as an option. The option of side airbags evolved from previously just front-seat side curtain airbags to full-length side curtain airbags, covering both rows of seats (in the XL model, all three rows). Â
