GMC Terrain 2021 is an SUV of the “K2” class with front-wheel or all-wheel drive. The second generation of the model debuted at the Detroit Motor Show on January 10, 2017.

The second generation of the GMC Terrain is built on the new modular D2XX platform. Externally, the SUV is practically not similar to its predecessor. The masculine silhouette of the Terrain stands out with many well-thought-out stylistic solutions, which together harmonize perfectly with each other. First of all, attention is drawn to the “floating roof” effect, achieved thanks to blacked-out rear pillars and an extended window line. The corners of the front part are framed by stylish C-shaped Bi-functional HID headlights, and between them shines a massive octagonal chrome grille. Completing the picture is a shiny decorative strip connecting the small fog lights.

The rear area is distinguished by similar C-shaped lights located on the large tailgate, under which a chrome decorative insert and a pair of rectangular exhaust outlets are placed. Due to the reduction of the internal cargo volume, the new model became slightly more compact; its overall dimensions L/W/H are now 4630/1839/1661 mm, respectively, and the wheelbase is 2725 mm.
