The GMC Terrain is a popular choice in the compact SUV segment, offering a blend of style, capability and technology. For the 2026 model year, the GMC Terrain gains some exciting updates and enhancements over the 2025 version. At Musson Patout GMC in New Iberia, LA, we're thrilled to showcase the differences between the 2025 and 2026 GMC Terrain to help you find the best fit for your lifestyle.
One of the biggest changes for 2026 is the addition of two new trims - the rugged AT4 and the luxurious Denali. These join the returning SLE and SLT trims to provide Terrain shoppers with even more options to fit their needs and preferences.
2026 GMC Terrain AT4: Adventure-Ready
The first-ever Terrain AT4 is engineered to take you off the beaten path. Featuring standard all-wheel drive, it's powered by a 1.5-iter turbocharged 4-cylinder engine making 175 hp and paired with a smooth-shifting 9-speed automatic transmission. A front steel skid plate and Goodyear Sport Terrain tires provide extra protection and traction when the pavement ends.
Unique AT4 exterior details include a black chrome grille, black roof rails, and exclusive 17-inch gloss black wheels. Inside, you'll find AT4-embroidered front head restraints, Jet Black leather-appointed seating, and red accent stitching.
If you're seeking a compact SUV that's as capable traversing trails as it is comfortable for the daily commute in New Iberia, the 2026 GMC Terrain AT4 delivers.
2026 GMC Terrain Denali: Pinnacle of Premium
Sitting at the top of the GMC Terrain lineup, the 2026 Denali trim surrounds you with elevated materials and amenities. A unique Denali grille with satin chrome accents provides an unmistakable look of luxury. 19-inch diamond-cut machined aluminum wheels add an extra touch of sophistication.
The Denali-exclusive interior boasts leather-appointed seating surfaces with unique Denali piping and French-stitched seams. Authentic ash wood trim and brushed aluminum accents further enhance the premium cabin. And with the Bose premium 7-speaker sound system, you can enjoy your music like never before.
Additional luxury and convenience features on the Denali include a hands-free programmable power liftgate, HD Surround Vision camera system, ventilated front seats, and more. For the height of GMC Terrain opulence, Denali delivers.
Bold New Colors for 2026
The 2026 GMC Terrain also gains two new exterior paint options to really make it stand out. Downpour Metallic is a rich, deep blue, while Glacier White Tricoat provides a bright, crisp look. These join other popular color choices like Ebony Twilight Metallic, Summit White, and Cayenne Red Tintcoat.
Well-Equipped Across the Board
No matter which 2026 GMC Terrain trim you choose, you'll benefit from a generous list of standard equipment. Every Terrain includes amenities like keyless open and start, wireless Apple CarPlay/Android Auto, heated front seats, LED headlamps and taillamps, and the GMC Pro Safety Plus suite of driver assistance technologies.
With seating for up to five, a maximum cargo capacity of 63.3 cubic feet, and a 1,500-pound towing capacity when properly equipped, the GMC Terrain is versatile enough for everything from errand running to weekend getaways. And fuel economy ratings of up to 26 mpg city/28 mpg highway mean you can go further between fill-ups.
