Coastal Dune has already been one of GMC’s most popular color options, and now they’ve brought it over to the Sierra EV and Hummer EV lineup.
It’s easy to see why. It has that perfect mix of clean and aggressive. A color that looks simple at first, but completely changes depending on the light.
On the Hummer EV, it gives it that rugged, almost military-style look. On the Sierra EV, it brings out the body lines in a completely different way.
Every Coastal Dune Sierra EV we’ve had has sold, and now with GMC adding it to more of the lineup, it’s only getting harder to ignore.
