Exterior Design & Features

Bold Attention to Detail

What’s a better first impression than delivering a stunning front fascia? The SLE and SLT trim both feature a bold wide grille, setting the tone for the rest of the exterior, while the premium multidimensional grille on the Denali trim reflects light in a stunning fashion thanks to its block style and satin chrome finish.

Brighten Up Your Drive

Brightening up the darkest of roads is the premium lighting group featured on the 2021 GMC Terrain. High-Intensity Discharge headlamps are found on the SLE and SLT, while the Denali receives a unique C-shape design. Both the SLT and Denali trims feature halogen fog lamps, and the Terrain’s tail lamps also feature the same signature C-shape design.

Roll in Style

You’ll find 17” silver painted aluminum wheels standard on the base SLE model, however, if you wish to upgrade your wheels, you’ll have plenty of options.

For a truly premium feel, the Denali features 19-inch bright machined aluminum wheels with premium Grey painted accents. Lastly, the Terrain Elevation Edition features daring 19-inch gloss-black painted aluminum wheels.
