General Motors is moving past the “aluminum versus steel” debate by adding a new material to the 2019 GMC Sierra tailgate: carbon fiber.
The box uses a 1-inch composite carbon-fiber thread, with CFRP sheets being molded to allow the plastic to bond and lock with the carbon fiber. The process happens in just one minute. In other words, it’s not a pure carbon fiber weave, which becomes clear upon closer inspection.
GMC believes the material will absorb dents more easily and resist corrosion better. As such, the days of a bed liner could be behind owners that opt for the CarbonPro, which also shaves 62 pounds over a regular steel bed.
The CarbonPro bed won’t be available for fall 2018 launch of the 2019 Sierra, and pricing for the innovative option hasn’t been announced yet.
