The GMC Terrain hit the market in 2010 as GMC’s smallest SUV, but because of its odd size, it lingered between the compact and midsize segments, often being called a “tweener” by some. It soldiered on for six years without any change until 2016 when GMC did a mild update. Even then, it wasn’t up to competing well and common complaints included that it was inferior in terms of technology and design. So, to remain relevant, GMC had to start working on the next-gen model, and it finally debuted at the 2017 Detroit Auto Show as a 2018 model. With the new generation comes a sleeker and stylish exterior design that leaves the SUV’s old, boxy nature in the past. It gets some new technology that includes LED daytime running lights, HID headlamps on some trim levels, and an updated infotainment system that finally brings it into the modern ages. Under the hood, you’ll find the option of three different turbocharged four-bangers, one of which is a diesel and a pair of all-new nine-speed automatic transmission. But, more importantly, it rides on GM’s new D2XX architecture which should mean a lower curb weight and a stronger framework.
