New 2027 GMC Terrain Redesign and Update Plan
Exterior & Interior
The exterior design of the 2027 GMC Terrain strikes a careful balance between ruggedness and elegance. A taller stance, wider fender flares, and bold wheel designs—ranging from 18 to 20 inches—give it a commanding presence on the road. The grille design changes slightly across trims, with the Denali receiving a chrome mesh pattern and the AT4 getting a blacked-out, more aggressive version. Roof rails are now integrated more seamlessly into the design, and optional two-tone paint finishes enhance personalization.
Step inside, and the cabin immediately reflects GMC’s push toward a more premium SUV experience. The seating layout has been refined to provide better thigh support, and new upholstery options include ventilated leather, perforated suede, and stain-resistant cloth for more rugged trims. The AT4 variant boasts all-weather floor mats, contrast stitching, and bronze accents, while the Denali goes for a more sophisticated palette of soft-touch leather, laser-etched detailing, and a suede headliner.
Rear passengers also see improvements, with increased legroom thanks to a re-sculpted floor pan and slimmer seatbacks. The panoramic sunroof is now larger, flooding the cabin with natural light. GMC has expanded storage solutions, introducing a sliding rear seat option and a configurable cargo floor for better versatility. Combined with a hands-free power liftgate and wider cargo opening, the Terrain remains a practical choice for both family use and adventurous lifestyles.
Inside, GMC takes the Terrain to a new level of luxury and convenience. The dashboard has been reworked with a cleaner layout, integrating a massive 12.3-inch infotainment display seamlessly into the center stack. New ambient lighting options, softer materials, and a wider use of real aluminum and wood trim elevate the cabin experience. The 2027 model also introduces more personalized features, such as customizable driver profiles and a refreshed digital gauge cluster that adapts based on driving mode.
Beyond aesthetics, the redesign focuses heavily on practicality and efficiency. Weight reduction through advanced materials improves fuel economy, while chassis tuning enhances ride comfort. Updated suspension geometry and a more refined steering system improve handling without sacrificing ride quality. The 2027 Terrain also benefits from upgraded noise insulation, ensuring a quieter and more premium cabin experience even at highway speeds.
