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: Dark Sky Metallic, Brownstone Metallic, Carbon Black Metallic, and Pacific Blue Metallic. Here’s our first look at the new Pacific Blue hue.
Assigned color code GA0 and touch-up paint code WA-619D, Pacific Metallic is the only blue hue available for the 2020 GMC Sierra HD. It is also one of five dark hues, and one of five metallic color options.
The Pacific Blue Metallic color option is not included in the base price of the all-new Sierra HD, and costs an additional $495, and is available in conjunction with all interior color combinations and trim levels.
