2018 GMC Terrain vs 2016-2017: 2nd vs 1st generation differences

The GMC Terrain has shifted to a new platform, and a new look. See all the changes between the first and second generations in this side-by-side comparison.

Like the 2018 Chevrolet Equinox, the new GMC Terrain moves from the old Theta platform to the D2XX platform. Both cars are considerably smaller than their outgoing counterparts, and significantly lighter too.

With square blistered wheel arches, the first-generation GMC Terrain always seemed like it was trying too hard to imitate the look of the GMC Sierra pickup truck.

With the second-generation Terrain, GMC has toned down the Sierra overtones, with less prominent arches, rounder shape, and softer details. It's better, but not entirely successful, with the C-shaped headlights and tail-lights looking rather forced.

By the end of the first-generation Terrain's run, the dashboard and interior were looking rather dated. The new one pushes the tough, I'm related to the Sierra and Canyon angle, but the 2018 Chevrolet Equinox's interior is much more appealing to us. At least the infotainment system is up-to-date.

Go for the top-of-the-range Denali trim, and there's a lot of chrome, especially on the grille. Under the bonnet, the Terrain has 1.5- and 2-litre turbocharged 4-cylinder petrol engines, and 1.6-litre turbo-diesel. The last two options make the Terrain really stand out against its sibling, the Chevrolet Equinox, which only has the 1.5-litre engine.
