GMC showed off the 2021 Terrain AT4, but it didn’t reveal any specific details and only stated that it “will feature a rugged exterior, confident capability and advanced technology.”
We can already see that the Terrain AT4 will look a bit more rugged thanks to its black grille, unique wheels and body cladding. We can also see that the entire 2021 Terrain lineup is also getting a slight facelift with restyled headlights and a slightly restyled grille.
With the introduction of the Terrain AT4, that means that every model in the GMC lineup will be available this fall with an AT4 version. The 2021 GMC Terrain AT4 is scheduled to arrive this fall.
