GMC launched the updated third-generation Terrain last year with just one trim on offer, but now it’s catching up. The 2026 GMC Terrain is now available in three trim flavors, now with a more rugged AT4 model and a luxurious range-topping Denali model going into production in Mexico. On top of an expanded lineup, the Terrain also gets more standard features for the new model year, as well, and thankfully, there doesn’t seem to be an immediate tariff impact on pricing.
