Design

The strong, angular C-shaped LED headlamps found on the 2021 GMC Sierra 1500 perfectly complement its rugged exterior and muscular hood (along with the power found underneath). A wide, athletic stance offers up serious attitude, while best-in-class crew cab front head and leg room ensures that the Sierra’s interior offers up just as much comfort. However, truck drivers are after one thing—utility—and this GMC pickup offers it in spades thanks to the available, world’s first Six-Function MultiPro Tailgate and a cargo bed with class-leading cargo volume. The industry first carbon-fiber composite bed is another option you won’t want to miss out on, while the SLT trim and up all feature premium, leather-appointed heated front seats. Rounding out the Sierra 1500’s impressive utility is the available 15” diagonal Head-Up Display, and first-in-class Rear Camera Mirror.
