New 2027 GMC Terrain Redesign and Update Plan
Exterior & Interior
The exterior of the 2027 GMC Terrain strikes a perfect balance between rugged durability and refined elegance. Up front, the new C-shaped LED DRLs frame the slim adaptive matrix headlights, while the multi-dimensional grille boasts intricate mesh patterns that differ between trims. Lower bumper air inlets and integrated fog lights have been restyled to improve airflow and off-road readiness. The rear receives slimmer taillights with dynamic turn signals and a hands-free liftgate that now responds faster to foot gestures.
Inside, GMC delivers a tech-forward and premium experience. A new 12.3-inch fully digital instrument cluster pairs with a 15-inch central infotainment touchscreen running GMC’s latest infotainment OS, offering faster response times and enhanced customization. Soft-touch surfaces, real wood or brushed aluminum accents, and contrast stitching elevate the cabin’s visual appeal. Ambient lighting with selectable color themes enhances nighttime driving comfort, while improved seating ergonomics support longer journeys with less fatigue.
Practicality remains a priority, with expanded cargo capacity thanks to a flat-folding front passenger seat and a split rear bench. Rear passengers enjoy increased legroom due to the stretched wheelbase, along with reclining seatbacks for added comfort. Optional ventilated rear seats and a dual-pane panoramic sunroof further enhance the sense of space and luxury. GMC’s Denali trim takes things up a notch with quilted leather upholstery, genuine open-pore wood, and a 14-speaker Bose premium audio system tuned specifically for the Terrain’s interior acoustics.
For 2027, GMC has also integrated advanced aerodynamics into the Terrain’s redesign, with functional air curtains, a reshaped rear spoiler, and flush-mounted door handles. The SUV’s stance appears more planted thanks to wider track dimensions, while available 20-inch alloy wheels with new finishes give the Terrain a premium presence. Special edition trims, such as the Denali Black Diamond and AT4 Adventure, will bring exclusive exterior touches, including gloss-black accents, roof rails, and rugged skid plates.
GMC’s update plan for the Terrain also focuses on sustainability. The brand has confirmed that the model incorporates more recycled and lightweight materials in its construction, from interior panels to sound-deadening insulation. This approach not only helps reduce the SUV’s carbon footprint but also enhances cabin quietness. The 2027 Terrain is part of GMC’s broader plan to electrify portions of the lineup, and while a fully electric Terrain isn’t here yet, the platform is designed with EV adaptability in mind.

Engine & Performance
Under the hood, the 2027 GMC Terrain offers an evolved powertrain lineup designed for efficiency, capability, and choice. The base engine is a refined 2.0-liter turbocharged inline-four producing around 255 horsepower and 275 lb-ft of torque, paired with an updated 9-speed automatic transmission for smoother shifts and better acceleration. Front-wheel drive is standard, with an advanced twin-clutch all-wheel-drive system available on higher trims for enhanced grip and performance in varied conditions.
For drivers seeking greener performance, GMC introduces a hybrid option using a 1.5-liter turbocharged engine paired with dual electric motors, delivering an estimated combined output of 220 horsepower while significantly improving fuel economy. This hybrid setup utilizes regenerative braking to extend electric assist, and can operate in EV-only mode at low speeds. Towing capability remains strong, with gasoline-powered versions rated up to 3,500 pounds when properly equipped, ensuring the Terrain remains a versatile companion for both city life and weekend adventures.
Driving dynamics are a highlight of the new Terrain, with chassis refinements, upgraded suspension tuning, and optional adaptive dampers for models like the Denali. Steering precision has been improved through recalibrated electric power steering, and noise insulation upgrades make the cabin quieter at highway speeds. For off-road enthusiasts, the AT4 variant includes all-terrain tires, hill descent control, and a dedicated Off-Road drive mode that optimizes throttle response, transmission mapping, and AWD power distribution for challenging terrain.
New 2027 GMC Terrain Fuel Economy
Efficiency is a clear focus for the 2027 GMC Terrain, with the base turbocharged gasoline engine expected to achieve around 27 mpg city and 33 mpg highway in FWD form, while AWD versions see only a modest drop in ratings. The hybrid variant is projected to return an impressive 38 mpg combined, making it the go-to choice for economy-minded buyers. GMC’s engine stop-start technology is smoother than before, and aerodynamic enhancements further reduce drag to maximize efficiency.
New 2027 GMC Terrain Safety Features
The 2027 GMC Terrain comes fully loaded with GMC Pro Safety Plus, a comprehensive suite of advanced driver assistance systems. Standard features include automatic emergency braking with pedestrian and cyclist detection, lane keep assist with lane departure warning, forward collision alert, and a high-definition rearview camera. Blind zone steering assist and rear cross-traffic braking further enhance awareness in crowded environments, while traffic sign recognition keeps drivers informed of changing speed limits.
GMC has also expanded semi-autonomous driving capabilities with the latest version of Super Cruise, available on higher trims. This hands-free driving system supports lane changes on compatible highways and now works in more mapped areas across North America. Enhanced camera and radar integration improves detection accuracy in adverse weather, while a driver attention system ensures engagement for safety. The Terrain’s adaptive cruise control with stop-and-go function also works more smoothly, making long commutes less tiring.
To further improve crash safety, the 2027 Terrain’s structure incorporates additional high-strength steel and redesigned crumple zones that better absorb impacts. Ten standard airbags cover all seating positions, including a new front-center airbag to protect against occupant-to-occupant collisions. An available 360-degree HD surround-view camera with transparent trailer view is a welcome feature for those who tow or navigate tight spaces. All these updates position the Terrain as one of the most safety-conscious SUVs in its class. New 2027 GMC Terrain Engine
