GM has taken the wraps off the 2015 GMC Sierra HD and the Chevrolet Silverado which are both based on the 1500 version of each company but are distinguished by a chrome front bumper made from one piece, along with a power dome hood, while at the back there’s a CornerStep bumper, as well as an EZ Lift and Lower tailgate. The flagship Sierra Denali comes with LED-infused headlights, polished stainless steel exhaust tip, body-colored bumpers and a different front grille. Other goodies include a Bose sound system, heated & cooled seats, Intellilink system and GPS.
