The 2020 GMC Sierra HD represents a complete overhaul and redesign with the fourth-generation model. In addition to the many changes and updates, including the switch to GM’s T1 platform and the addition of the all-new Sierra AT4 HD model, the nameplate also adds four new exterior color options to its palette: Pacific Blue Metallic, Dark Sky Metallic, Brownstone Metallic, and Carbon Black Metallic. Here’s our first look at the new Carbon Black hue.
Assigned color code GCI and touch-up paint code WA-621D, Carbon Black Metallic is one of two black hues available for the 2020 GMC Sierra HD, along with Onyx Black. It is also one of five dark hues, and one of five metallic color options.
