The 2025 GMC Terrain is poised to introduce a brand-new third generation for the crossover nameplate, bringing with it a long list of changes and updates. Now, GM Authority spy photographers have caught the upcoming 2025 GMC Terrain testing on public roads as a camouflaged prototype, giving us an early look at what’s to come in terms of exterior styling.
Although this 2025 GMC Terrain prototype is draped in heavy vinyl covers, there’s still quite a few interesting design elements to pick out.
The front end, for example, shows a new front fascia with revised lighting. Unlike the two-tiered lighting seen on the 2025 Chevy Equinox, this 2025 GMC Terrain prototype appears to incorporate a new version of GMC’s signature C-shaped headlamps, including a singular lighting cluster around the upper corners of the fascia. The grille was also updated, sticking to the broad design seen on other GMC products, while around the upper section of the grille, there’s a rectangular section that likely accommodates the requisite GMC badge.
The side view looks as though it’s somewhat similar to that of the next-gen 2025 Chevy Equinox, with a tall, utility vehicle design and flat roofline. Under the heavy black camo in the rear, the 2025 GMC Terrain is expected to incorporate a flying-buttress design for the C-pillar. In the corners, we spot a set of thin-spoked wheels.
The rear end is also draped in black vinyl camo, but we can expect to see revamped tail light clusters, the shape of which is hinted at by placeholder units on this prototype. The taillights will likely incorporate further C-shaped housings to bookend with the headlights, as well as additional lighting on the tailgate. Twin exhaust outlets are seen under the rear bumper.
The overall appearance will be more rugged and truck-like than that of the current model, as confirmed by GM President Mark Reuss. Under the hood, the third-gen 2025 GMC Terrain is expected to cradle a new small-displacement turbocharged engine.
