The 2027 GMC Terrain keeps its mechanical foundation straightforward while allowing its 3 trims to head in noticeably different directions. Elevation covers the core compact-SUV brief, AT4 adds hardware for rougher surfaces, and Denali concentrates on comfort and equipment. For Clinton Township, MI, and Detroit area drivers, all 3 combine seating for 5, a turbocharged engine, substantial standard driver-assistance technology, and up to 63.5 cu. ft. of cargo capacity.
One Turbocharged Engine Across the Lineup
Every 2027 Terrain uses a 1.5L Turbo 4-cylinder producing 175 hp, paired with an 8-speed automatic transmission. Elevation offers available AWD, while AT4 and Denali include AWD as standard. Properly equipped models with the available Trailering Package provide up to 1,500 lbs. of towing capacity and include an In-Vehicle Trailering App. Selectable drive modes are also available, with AT4 adding an exclusive Terrain Mode.
Three Trims Take Different Approaches
Elevation starts with heated front seats, a heated steering wheel, a 15-inch diagonal Premium GMC Infotainment System, an 11-inch diagonal Driver Information Center, and more than 16 standard safety and driver-assistance technologies. AT4 changes more than the appearance, adding standard AWD, a lifted ride height, off-road-tuned suspension, Hill Descent Control, a front skid plate with steel underbody protection, red recovery hooks, and 17-inch wheels with all-terrain tires. Denali takes the opposite route, pairing standard AWD with premium suspension tuning, heated and ventilated front seats, heated rear outboard seats, HD Surround Vision, a Rear Camera Mirror, and 19-inch machined-face aluminum wheels, with 20-inch wheels available.
The Cabin Makes Good Use of Its Compact Dimensions
The Terrain accommodates up to 5 passengers and provides 29.8 cu. ft. of cargo capacity behind the second row. Lowering the 60/40-split rear seat increases maximum cargo capacity to 63.5 cu. ft., while an underfloor storage compartment gives smaller belongings a separate place to live. That combination is particularly handy in a compact SUV because it allows the main cargo area to remain open for larger luggage, shopping, or equipment instead of filling it with loose smaller items.
Large Displays Are Standard
Every Terrain receives a 15-inch diagonal Premium GMC Infotainment System and an 11-inch diagonal Driver Information Center. Buyers can also add a panoramic sunroof, and an AutoSense Power Liftgate, which can open when the driver approaches the rear of the vehicle with the key fob.
Driver Assistance Is Extensive From the Start
More than 16 safety and driver-assistance technologies are standard, including Rear Park Assist, Teen Driver, Side Bicyclist Alert, Adaptive Cruise Control, and Rear Cross Traffic Braking. This means moving through the trim range isn't simply a case of paying upward to acquire the basic assistance systems.
