Refined Details

The terrain has been crafted down to its finest details to stand out amongst the crowd. The SLE and SLT see a bold grille whose style reverberates across the rest of the vehicle, while the grille on the Denali trim modifies it through a grille insert and block style with a satin chrome finish.

Lighting Features

Illuminating all of that premium style is the variety of lighting around the SUV. High-Intensity Discharge headlamps are found on the SLE and SLT, while the Denali sees a signature C-shape design on the front. The SLT and Denali add on halogen fog lamps, and in the rear are those classic C-shape lights again.

Premium Wheels

Coming standard are 19-inch bright machined aluminum wheels, finished off with premium Grey painted accents. The SLT invites on 19-inch machined aluminum wheels with Grey painted accents. For a truly bold look, explore ruggedness of the AT4 Terrain, or the luxurious style of the Terrain Denali SUV.

For your friends and family, or to store items up to 8 feet long, the Terrain is ready to exceed your demands.

Premium Interior Touches

The beauty of the Terrain comes down to how it meshes elegance with its utility features. Real aluminum trim and accents on the SLT provide a sumptuous contrast across the interior. Soft touch material as well on the SLT, and a leather-wrapped steering wheel allow for a smooth touch inside the cabin. The Denali puts forth the top of interior luxury with French stitch leather-appointed front seats.

SkyScape Sunroof

Take a break and enjoy the wonders outside of your vehicle, all from the comfort presented inside. The available SkyScape sunroof stretches from the front seats to the second row, so all inside can enjoy the sky above.

Performance & Capability

Engine Power & Efficiency

Efficient and powerful is the Terrain’s engine, a 1.5L gas turbo-charged powertrain that produces 170 horsepower with 203 lb-ft of torque, matched to a 9-speed transmission. On both the FWD and AWD the Terrain stays economical for long trips between gas station visits.

Traction Select System

The Traction Select System on the Terrain allows for quick adjustments when the environment around you changes. FWD models come with a Normal Mode and available Tow/Haul and Snow modes. For tackling tough terrain and conditions, the AWD and Off-Road modes allow you to tune your vehicle to remain stable over everything from ice to gravel to sand and more.

Denali Premium Suspension

The Terrain Denali edition is a premium suspension that delivers an incredibly smooth ride. Its valve internal to the struts and shocks allows for this comfortable drive, while the urethane spring isolators help to cut down on road noise when driving over rough environments.

High Definition Surround Vision

Get a bird’s eye view all around your Terrain with this High Definition Surround Vision system. Multiple cameras combine to create a digital overhead image. It works alongside the Rear Vision Camera, operating at low speeds to detect nearby obstacles and to make your next parking job a breeze.

Automatic Parking Assist

Available is this system that will make your latest journey into a parking lot your best yet. The Automatic Parking Assist can both search for a spot and help you steer into it. Whether parallel or perpendicular, the system steers while you brake and accelerate with guided gear shifting.


GMC Pro Safety (and Plus)

You never know what you may come across on the road, but what you will know is that you’ll always be safe behind the wheel of the Terrain. GMC Pro Safety comes standard, a suite of safety and driver assistance features that help notify you of hazards and help you overcome them. Included are features like Lane Keep Assist, Automatic Emergency Braking, Forward Collision Alert and more. GMC Pro Safety Plus provides for even more safety features.

Lane Change Alert

Change lanes with confidence thanks to the Lane Change Alert, complete with Side Blind Zone Alert. Side mirror visual alerts appear when a vehicle in a neighbouring lane is driving quickly or slides into your blind spot. Avoid unnecessary collision and be aware of all that’s in each lane beside you.

Rear Park Assist

You won’t have to eyeball ever again whether or not you’re close to touching another vehicle when parking. The distance alerts from this Rear Park Assist let you know if you’re close to hitting an object. It activates in reverse when at a low speed.
