What’s new for the 2018 GMC Terrain?

Available at six trim levels (SL, SLE, SLE Diesel, SLT, SLT Diesel, and Denali), the 2018 GMC Terrain comes new and improved. The 2017 GMC Terrain was available at five trim levels, making the 2018 model even more customizable. The exterior of the vehicle has new, defined contouring to give it a leaner, sleeker look. The wheels have been slimmed down from last year’s 18-inch alloy wheels to new 17-inch aluminum wheels for a lighter touch.

In addition to the standard safety features on the 2018 Terrain, the new model comes with an extremely important feature: an electronic rear seat reminder. This feature allows a notification to pop up on your dashboard, as seen above, to remind you to check the backseat before you get out of the car. This feature is to help prevent animals, children, or other items from being left in the back seat unattended. The vehicle also comes with Teen Driver Mode, allowing parents to set restrictions and other controls for their teenager’s time behind the wheel, even when the parents are not in the car.
